Agentic transformation

Rebuild how your organisation works around AI agents.

Anyone can buy AI tools. Rebuilding how thousands of people work around agents, and making it stick, is the hard part. That is the whole practice of an AI transformation partner, and every price for it is published on this page.

Led by the founder

James Rooney, branded a “delivery firefighter” for landing transformations at the world's most complex organisations, now embedded as an Agentic Lead.

150+ teams advised at HSBC against a $102M budget, and the target operating model he co-led the design of, prepared for global rollout to 500 teams. He is currently embedded as interim Agentic Lead inside a London specialty insurance business. That is the operator you get, and he provides partner oversight on every engagement Tenhaw takes.

AI Readiness Audit

Find where AI could make work better. Test the possibilities with your team.

Investment
Fixed price · £44,000
4 weeks

The AI Readiness Audit gives you four weeks to explore where AI could help across your product, internal processes, operations and software delivery. We work with your team to test two or three promising workflows as working prototypes against your real data, inside your own tenancy. The fee is £44,000 fixed, excluding VAT. Bring the work your people know best, including the exceptions that make it interesting. Their examples and feedback shape what we test. You leave with the prototypes and a costed plan in three-month increments, capped at twelve months, ready for your board to decide what to fund. The code lives in your repositories; you own the deliverables on payment, whether or not you continue with us.

What you get
  • Two or three working prototypes, built with your engineers against real data in your tenancy, with measured accuracy, an assessment of confidence in the results and an estimated run cost for each
  • A heat map of opportunities across product, internal processes, operations and software delivery, ranked by expected return and feasibility
  • A record of data, platform, risk and regulatory constraints, including what would need to change
  • A view of how AI could improve software delivery, using your current delivery data as the baseline
  • A practical assessment of the skills, time and support your people need to use the proposed workflows
  • Changes to roles, decisions, incentives and working practices that would help adoption
  • A costed plan in three-month increments, capped at twelve months, with dependencies and review points
  • An investment case your finance team can examine, with assumptions and confidence attached to the figures
  • Prototype code and written findings you own on payment of the applicable fees, with production work scoped separately
Who turns up

James Rooney leads every audit personally, with a senior operator exploring the work alongside your teams and a build engineer developing the prototypes with your engineers.

02Fastest proof

Agentic Proof of Concept

Pick the workflow. Two to four weeks later, look at a working thing.

Investment
Fixed price · £20k–£55k
2–4 weeks

An Agentic Proof of Concept takes one real workflow and gives you a working agentic system against it, at a fixed price, in two to four weeks. Your engineers pair-program with ours throughout, running our published AI-engineering-first method, so the capability stays with you. On a recent engagement that meant a working proof of concept in two weeks, extracting information from PDFs into business intelligence on Azure, ground that had previously taken roughly twelve months.

What you get
  • A working agentic system against one real workflow, in your environment
  • The full requirement corpus as structured markdown, yours to keep and extend
  • A documented gap-and-contradiction analysis, surfaced before any code was written
  • Your own engineers able to run the method, measured, not assumed
  • An assessment of what productionising it would take, scoped and costed
Who turns up

One or two Tenhaw engineers, pair-programming with your people throughout.

Full detail, week by week, and the fit test →
03Design first

Agentic Design Team

A pair who design the AI-native operating model, and the agentic systems to run it at scale.

Investment
£35k–£55k / month
2–4 months

An Agentic Design Team is a pair of senior Tenhaw practitioners, one operating-model lead and one agentic architect, who design what your organisation needs to run agents at scale. The work is AI-native organisation design: the target operating model and the technical architecture are designed together, deliberately, because separating them is why scaling stalls. It runs at £35,000–£55,000 per month, typically over two to four months.

What you get
  • Target operating model for an AI-native organisation, with roles defined by the decisions they own
  • Agentic system and infrastructure architecture: platform, data foundations, integration and security
  • Governance framework making agent decisions auditable rather than theoretical
  • Accountability mapped across the model before a single agent is deployed
  • Human-in-the-loop boundaries defined per decision class, with escalation paths
  • A sequenced build plan your teams, ours, or a third party could execute
Who turns up

Two senior practitioners, an operating-model lead holding the interim Head of AI seat and an agentic architect.

04Full delivery

Agentic Build Team

A team of three who build and ship it, under partner oversight.

Investment
£70k–£85k / month
6–12 months

An Agentic Build Team is three forward-deployed Tenhaw practitioners, an interim agentic lead, an engineer and an adoption lead, who build and ship agentic systems inside your estate under partner oversight from James Rooney. You get working software in your estate every month, not a distant go-live, and the team pair-programs with your own people so the capability stays behind. It runs at £70,000–£85,000 per month. In role terms it is an interim head of AI delivery and the team under them, supplied as an engagement rather than three permanent hires.

What you get
  • Agentic workflows built and shipped inside your estate, delivering measurable value every month
  • Adoption owned explicitly and measured
  • Your own engineers pair-programmed into the method, with the transfer measured
  • Governance, audit trails and human-in-the-loop gates built in rather than retrofitted
  • Partner oversight from James Rooney, not an account-management layer
  • A dated exit with the capability owned by your permanent team
Who turns up

Three forward-deployed practitioners (interim agentic lead, engineer, adoption lead) under partner oversight from James Rooney.

05Supplier-agnostic

Programme & Delivery Management

We will govern the programme whether or not we are building any of it.

Investment
£18k–£35k / month
Programme duration

Tenhaw provides programme and delivery management for agentic transformation programmes, including programmes delivered entirely by other suppliers. In the words most buyers use, you are hiring an AI programme director, an interim delivery director or a fractional AI delivery lead, supplied as an engagement rather than a permanent hire or an agency placement. We will govern a mixed estate of systems integrators, internal teams and specialist vendors as readily as we own the full stack, and we will say when another supplier is better placed to build something. It draws on a decade running delivery at HSBC, Anglo American and Discovery, and runs at £18,000–£35,000 per month.

What you get
  • Programme governance a board will actually steer with, not a status pack
  • Probabilistic delivery forecasting from real throughput, not single invented dates
  • Cross-supplier dependency management, including where we are one of the suppliers
  • Supplier performance reporting to one standard, Tenhaw's own workstreams included
  • Risk and issue management with escalation that resolves rather than records
  • Benefits tracking against outcomes priced in currency
Who turns up

One senior programme lead, an AI programme director or delivery director depending on the shape of the programme, with partner oversight from James Rooney and scaling with programme size. Available fractionally, from around three days a week.

This is not for you if

You want a tool and nothing else.

  • You want tooling procured and nothing else changed.
  • You are looking for a deck-writing consultancy with no hands on the keyboard.
  • Your leadership is not ready to redesign roles around agents.

How we work

Forward-deployed. Outcome-priced. Yours to run when we leave.

Every engagement is backed by forward-deployed product engineers who embed with your teams and build the real thing. Strategy decks do not change how people work, working systems do.

  • Engineers in your repos, your Slack, your stand-ups
  • Working systems your engineers helped build, not a slide deck
  • Bespoke internal systems built around your data

James Rooney provides partner oversight on every engagement, and leads the audits personally. Every person on your engagement is senior, with no pyramid of juniors behind them. How the associate model works.

The engineering standard we build to is open source: 72 rules with stable identifiers and RFC 2119 severities, written to be enforced by an agent rather than remembered by a human. You can read it before you hire anyone. Read the handbook on GitHub →

01

Forward-deployed

Our engineers and operators sit in your Slack, your stand-ups, your decision rooms. We are not consultants writing decks.

02

Priced before you commit

Fixed scope, fixed outcome, defined price, with what “done” means written down before we start. Every figure derives from a published rate card.

03

Sustainable handover

Every engagement ends with your team owning the agentic capability, not us holding the keys.

04

Built on The Tenhaw Way

A decade of landing change at the world’s hardest organisations, codified into a method and now pointed at agentic transformation.

05

Designed to end

Retainers run on 30 days’ notice from either side. You own all work product and documentation produced up to the point of exit, including any code written inside your estate. The exit date is agreed at kickoff rather than negotiated at the end.

If forward-deployed is not how your organisation buys, say so on the call.

How we staff it

Two team shapes. Two or three senior people.

The operating model, the engineering and the adoption have to move together, so we staff them in one embedded squad. No pyramid of juniors, and the people who pitch are the people who deliver.

Everyone on the engagement is someone James Rooney has already delivered alongside, screened to BS7858 standard before any client access, and not substituted without your written agreement. Cover levels, and the assurance still in progress, are published on our security page.

Measurable value delivered every month

We agree a target value in currency for every outcome. Each month, we commit to a share of that value and report what was delivered and what changed in the work. A month with no measurable value is reported as a failed month. Your team can use those findings with us to decide what to improve next.

Which shape you need depends on scope. Thirty minutes is enough to say.

What is Tenhaw?

Tenhaw is a UK AI consultancy and AI delivery partner, based in London and registered in England and Wales. We help large organisations redesign how work gets done with AI, connecting the operating model, the systems people use and the support they need to work differently. Our forward-deployed teams embed two or three senior people in your organisation; a build team typically brings an agentic lead, an engineer and an adoption lead. Your team's knowledge of the work shapes what we design, build and test together. We commit to measurable value delivered every month and report against it, giving you evidence to review as the work progresses. Tenhaw provides professional services rather than a software product.

Is Tenhaw an AI consultancy or a delivery partner?

Both. Tenhaw helps you decide where AI could improve the work, then provides the people to design and deliver the change within an agreed scope. The consultancy work can begin with a fixed-price AI Readiness Audit. It examines your product, internal processes, operations and software delivery, what your data estate and platform can support, and the evidence your risk function needs before a system can be relied on. Your team's examples and constraints help us choose which possibilities to test.

If you continue into a build, our people carry that understanding into delivery inside your estate and repositories, alongside your engineers. We connect the technical work with decisions about roles, ownership and adoption, so your people can help shape the system and learn how to improve it. You can also engage Tenhaw to run a programme built entirely by other suppliers. We agree responsibility for the work and its outcomes; you do not have to buy engineering capacity from us to get programme support.

Our decade of experience is in delivery and transformation. The agentic evidence includes a working proof of concept built in two weeks inside a live, regulated London insurance business, paired throughout with a client engineer. That system is now being productionised as a separate stage. The case studies distinguish the established delivery record, the proof of concept and the work still under way.

We do not use the word agentic. What kind of firm is Tenhaw?

An AI consultancy and an AI delivery partner. The same firm answers to generative AI consultancy, enterprise AI consultancy, and digital transformation consultancy where the programme in question is an AI one. Three categories it is not: a staffing agency, because nobody is placed by the day into someone else's plan; a compliance or assurance consultancy, because it builds audit trails into systems rather than certifying anyone against a standard; and a product vendor, because there is no tool underneath the advice.

What does an AI delivery partner actually do?

An AI delivery partner takes responsibility for getting an agreed system into production and helping people use it in their working day. The scope matters: an audit or proof of concept answers earlier questions, while a production build includes the work needed to make the system ready for live use.

In practice, delivery connects five jobs. First, decide with your team which workflows AI could help with, what order to tackle them in and what each improvement is worth in currency. Second, design the operating model: whose work changes, which decisions an agent can make, who remains accountable and what happens when it gets something wrong. Third, build inside your estate and repositories alongside your engineers, so they learn how the system works as it develops. Fourth, specify and test the evidence during design: evaluations, audit trails, escalation routes and the points where a person checks or approves an action. Fifth, help people use and improve the new workflow, measuring adoption and inviting their feedback.

Ask what you will be able to review in the first thirty days. Tenhaw commits to measurable value delivered every month and reports a month that delivers none as a failed month. That gives you a clear point to examine the evidence, understand any obstacle and decide what should happen next.

What does Tenhaw actually do?

Tenhaw offers five services across three tracks: explore a possibility, design and build the change, or manage delivery. There are two ways to start exploring. The AI Readiness Audit is £44,000 fixed over 4 weeks, examining your product, internal processes, operations and software delivery and ending in working prototypes. An Agentic Proof of Concept costs £20k–£55k fixed over 2–4 weeks and builds a working system against one real workflow; productionisation is a separate scope.

For the next stage, an Agentic Design Team of two senior practitioners costs £35k–£55k per month and designs the operating model and agentic architecture together. It produces the design and a build plan that you can take forward with your own team, another supplier or us. An Agentic Build Team of three under partner oversight costs £70k–£85k per month and builds and ships the system alongside your people.

Programme and Delivery Management is available separately at £18k–£35k per month. We can govern a programme delivered entirely by other suppliers, with no requirement that Tenhaw builds any of it. All prices exclude VAT. The right starting point depends on what you already know and the work you want help taking forward.

How much does Tenhaw cost?

Tenhaw publishes its engagement prices and the day rates behind them. The partner rate for James Rooney is £1,560 a day, a senior practitioner is £1,250 and an associate is £950. All fees exclude VAT.

The AI Readiness Audit is £44,000 fixed over four weeks. An Agentic Proof of Concept is £20,000–£55,000 fixed over 2–4 weeks. Monthly fees are £35,000–£55,000 for an Agentic Design Team, £70,000–£85,000 for an Agentic Build Team, and £18,000–£35,000 for Programme and Delivery Management. The rate card uses twenty billable days a month to calculate monthly prices. Fixed-price engagements have an agreed fee for a defined scope. We agree what will be delivered and carry the risk of delivering that scope at the agreed fee.

Your proposal sets out the team, scope and fee so your finance team can see what it covers. Budget separately for any pre-agreed expenses charged at cost and model or platform use on your own accounts. Monthly engagements can end on 30 days' written notice from either side.

Who runs Tenhaw?

James Rooney, founder and Transformation Director. He has spent a decade working on delivery transformation at HSBC, Microsoft, Sky, F1, Discovery and Anglo American, including programmes with $100M+ budgets in scope. At HSBC he co-led the design and piloting of the target operating model prepared for global rollout to 500 teams.

James has brought that experience into a published methodology called The Tenhaw Way. He leads every AI Readiness Audit personally and provides partner oversight on every engagement, with personal accountability for the outcome. Your proposal makes the delivery roles clear, so you know who will work alongside your team and which decisions to bring to James.

What is a forward-deployed operator?

A forward-deployed operator is a senior practitioner who works inside your organisation with an agreed reporting line and real decision rights. They join the work where it happens: your meetings, your systems and the decisions your team needs to make.

At Tenhaw, the role connects understanding the workflow with taking responsibility for changing it. Depending on the engagement, that can mean designing roles and approval routes, building systems alongside your people, or coordinating delivery across suppliers. Your colleagues contribute the exceptions and practical knowledge that shape the work. Agreeing the operator's responsibilities and authority at the start helps everyone know which decisions they can take and when to involve you.

Is Tenhaw a software product?

No. Tenhaw provides professional services for agentic transformation, embedding senior operators in your organisation to work alongside your people. You engage a team for a fixed-price piece of work or a monthly engagement. There is no Tenhaw seat count, software licence fee or software renewal. Any model or platform use in your environment is charged separately on your own accounts, so include that when planning the running cost of a system.

Tenhaw previously developed delivery-management software, and some third-party directories still describe that earlier product. The business today is a consultancy selling professional services. If you found us through one of those listings, the services and pricing pages explain the work available now.

How is Tenhaw different from a large consultancy?

Tenhaw's team shape suits work where a small number of senior operators can build alongside your people and take clear responsibility for delivery. We publish our prices, commit to measurable value delivered every month and report against it. On an Agentic Build Team engagement, the scope includes a contractual exit date and support for recruiting your permanent team, so you can plan who will carry the work forward.

The case studies show how that has worked in practice. At Tecknuovo, we established a Portfolio Management Office from scratch and ran it across 19 projects, including public-sector delivery for HMRC, the MOD and Thames Water. Our role was portfolio governance; Tecknuovo's teams delivered the projects. In a separate engagement, we built a London specialty insurer's PDF-to-business-intelligence workflow on Azure as a two-week proof of concept, paired throughout with one of its engineers. Productionisation is a separate stage.

A large firm may be the better fit when you need 200 people across twelve countries. Compare the team each proposal names, the responsibilities it takes on and the capacity you have internally. That gives you a practical way to judge which arrangement suits your work.

What size of organisation does Tenhaw work with?

Typically organisations from 500 to 100,000+ people where agentic transformation requires changing how many teams work, not just adopting a tool. That work has been delivered inside HSBC, Microsoft, Sky, F1, Discovery, Anglo American, Greggs, Yondr and YOOX NET-A-PORTER.

Do you work with UK enterprises only?

No. Most Tenhaw engagements are with UK enterprises, and we also work across Europe and the United States. Past work has been delivered in the UK, Australia, the USA and Singapore. Tenhaw LTD is registered in England and Wales and based in London. For a British buyer, that means a UK contracting entity, invoicing in sterling and a team available for on-site work without an international flight. Associates complete screening to BS7858 standard, including right-to-work checks, before any access to your estate.

What matters for an embedded engagement is being available for your team's work and decisions. We agree the on-site time and working-hour overlap your people need, including access to the colleagues who understand the process and can review what we build. We can take work wherever that involvement is practical, and will tell you on the first call if we cannot provide it. Outside the UK, expect a UK-based team travelling to you: Tenhaw has no local office. Travel requirements and costs are agreed with you before they are incurred.

Where is Tenhaw based and where does it work?

Tenhaw LTD is registered in England and Wales and based in London, and delivers across the United States, the United Kingdom and EMEA. Engagements run across the United Kingdom, Europe and the United States, and past work has been delivered across the UK, Australia, the USA and Singapore.

How do we start working with Tenhaw?

A 30-minute discovery call with James Rooney. You leave with a rough scope whether or not you engage Tenhaw. Most organisations then start with the fixed-price AI Readiness Audit, which is deliberately sold as standalone work with its own deliverable and no obligation to continue.

Why do most AI transformations fail?

Because the technology changes and the organisation does not. A pilot succeeds inside one team that has been given permission to work differently, then fails to scale because scaling requires redefining roles, moving decision rights and rewriting governance across functions the pilot team has no authority over. Adoption typically plateaus around 30%, the people who were always going to adopt, and more training does not move it, because awareness was never the constraint. That plateau is a pattern we have observed across the engagements we have run rather than a published statistic.

Our Copilot rollout stalled, what now?

Diagnose why before buying anything else. Stalled Microsoft 365 Copilot and Gemini rollouts usually fail on workflow, not licences. The assistant sits beside the work instead of inside it, so nothing measurable changes and the renewal gets hard to defend. The AI Readiness Audit traces the real workflows, prototypes two or three candidates against your own data, and hands your board a sequenced, costed plan. Four weeks, £44,000 fixed. A recommendation to stop is a valid outcome.

We have shadow AI across the business, where do we start?

With an inventory, because you cannot govern what nobody has counted. People reached for consumer tools because the sanctioned route was slower than the work, which normally makes shadow AI a symptom rather than a discipline problem. The AI Readiness Audit establishes what is genuinely in use across functions, which workflows depend on it and what data it touches, then separates what to sanction from what to stop and what to rebuild properly. Four weeks at a fixed price, with the constraints written up for your risk function.

How do we assess our AI maturity?

Not with a score out of five. A maturity model tells you where you sit against other organisations, which is interesting and rarely actionable. The AI Readiness Audit answers the question underneath it: which workflows AI could take, across the product, the internal processes, operations and the development process itself, what your data estate and risk appetite genuinely allow, where your workforce is ready and where it is not, and what to do first, second and third with costs attached. The output is a costed plan in three-month increments, capped at twelve months, rather than a maturity score.

We have bought five AI tools that do not talk to each other

That is tool sprawl, and usually a buying problem before it is an integration problem. Separate functions bought overlapping point solutions against separate business cases, a contact centre assistant here and a document tool there, with nobody owning the whole. The AI Readiness Audit maps what each tool was bought to do, where two of them cover the same job, and what each costs to run, then sequences what to keep, what to retire, and which workflow nothing you own currently covers. Vendor consolidation is an output of that, not the starting question.

What should AI due diligence cover?

Five things, in this order: what is genuinely in production against what is still a pilot, whether the claimed benefit is measured or asserted, what the systems cost to run at current volume, what data and model risk has been accepted and by whom, and whether the capability sits with named employees or with one supplier. Tenhaw runs this as an AI Readiness Audit scoped to the target or the business unit under review. It is an operational read, not legal or financial due diligence.

How does Tenhaw staff an engagement?

In forward-deployed teams of two or three senior people. On a build team that is an Agentic Lead who owns the operating model and decision rights, a Forward-Deployed Engineer who builds and ships inside your estate, and an Adoption Lead who helps your people use and improve the new workflow. Squads are founder-led, with James Rooney personally accountable for every engagement. Associates come through work he knows at first hand or referrals from people he has delivered with, and every practitioner on your engagement is senior.

How often does Tenhaw deliver something?

Measurable value is delivered every month. That is the monthly cadence engagements are structured around, and it means you can judge the work on evidence within the first thirty days rather than at a milestone months away. The squad commits to it and reports against it; a month that delivers no measurable value is reported as a failed month. Hold us to that from month one. It is why engagements are retainer-shaped, not milestone-shaped.

Are HSBC, Microsoft and Sky Tenhaw clients or the founder's previous employers?

Both, and the distinction matters. James Rooney worked inside HSBC, Microsoft, Sky, F1 and Discovery in delivery and transformation roles, on contract and in permanent positions. Other engagements (including Anglo American, Yondr, Greggs, Colart, Tecknuovo and Globelynx) were delivered under the Tenhaw banner. Several predate the company's incorporation and were delivered by James personally on contract; we will walk you through which is which on the call. Case studies name the client wherever we have their permission; our current agentic engagement is confidential at the client's request and is written up unnamed, and every one states where an outcome was a pilot or proof of concept rather than a production rollout.

Does the audit price change with the size of our organisation?

No. The AI Readiness Audit is £44,000, fixed in writing before the engagement starts, and it does not move with the number of business units in scope, how much prototyping is involved, or how many sites need time on the ground. Those things shape what goes into the four weeks and what comes out of them, which is what the scoping conversation settles. They are not a lever on the price. If the work genuinely will not fit inside four weeks, we say so before you commit rather than repricing halfway through.

What happens if the engagement is not working?

Retainer engagements run on 30 days' notice from either side, and the fixed-price audit is a defined deliverable rather than a subscription. You own all work product and documentation produced up to the point of exit, including any code written inside your estate. Tenhaw would rather stop a bad engagement at month two than defend it to month nine.

What happens when Tenhaw leaves?

You own the capability. Recruiting your permanent team is a stated deliverable of the retainer and programme engagements, the exit date is agreed at kickoff rather than negotiated at the end, and on a build engagement the final sixty days are a documented handover with a decreasing-involvement taper. The commercial model is designed so that the engagement ends.

How does Tenhaw avoid supplier lock-in?

Structurally, in four ways. First, working software is deployed on your infrastructure, in your repositories, under your controls and your organisation's policies, so nothing needs migrating off Tenhaw's estate when the engagement ends. Second, your own permanent people are upskilled by pair-programming with ours for the whole build, and that transfer is measured rather than assumed. Third, the method is published in full and free to adopt without hiring us. Fourth, the exit is contractual: thirty days' notice either way, the exit date and taper agreed at kickoff, and you own all deliverables, documentation and code on payment.

How does a forward deployed engineer work inside our teams?

A forward deployed engineer works from inside your organisation rather than from a supplier's office: in your repositories, your Slack, your stand-ups and the rooms where decisions actually get made. They build against your data, ship through your own pipelines and pair with your engineers while doing it, so what lands is a system your people helped write rather than one delivered over a wall. On a build team the engineer sits alongside an agentic lead and an adoption lead, under partner oversight from James Rooney, and everyone is screened to BS7858 standard before any client access. They are accountable for shipping, not sitting in an advisory seat.

What does month one with a UK AI delivery partner look like?

Kickoff, access, and something built before the month is out. A UK AI delivery partner should spend week one settling what the outcomes are, what each is worth to your business in currency, who owns which decisions once an agent takes part of the work, and when the engagement ends, with the exit date agreed at kickoff rather than negotiated later. Screening and account provisioning run alongside that, because access is usually the practical constraint. From there the team works in your stand-ups and your repositories rather than behind a discovery phase, and you should be able to judge month one on something working rather than on a plan.

Is it too early to engage if our leadership will not redesign roles yet?

It depends whether they have refused or simply have not been convinced. If leadership has ruled out changing roles and decision rights, we are the wrong firm, because every engagement moves who owns the decisions an agent now makes and no amount of tooling substitutes for that. If they are unconvinced rather than opposed, that is what the AI Readiness Audit is for, four weeks at £44,000 fixed, ending in working prototypes against your own data and a costed sequence your board can argue with. A recommendation to stop is a valid outcome, and week four is a cheap place to reach it.

Can you just roll out the tools without changing how people work?

No, and it is the clearest item on our not-for-you list. Procuring licences and configuring a tenancy is work a reseller or your existing licensing partner will do faster and more cheaply than we will. What Tenhaw sells is the harder half: deciding which workflows go to agents, redesigning the roles and decision rights around them, building the systems inside your estate, and getting people to actually work the new way. If the tools are already bought and nothing has changed yet, that is a different conversation, and the fixed-price audit is where it starts.

Do we get documentation as well as working software?

Both, though the documents exist because someone needs them rather than to fill a deliverables list. The audit ends in working prototypes against your own data alongside a sequenced plan with costs attached; a design engagement produces the target operating model, the architecture underneath it and the governance around agent decisions; a build engagement ends in a documented handover as well as a running system. What you will not get is a strategy deck with nothing behind it, because a deck does not change how anyone works. You own all of it, code and documentation alike, up to the point of exit.

Why are your engagements retainers rather than milestone payments?

Because a milestone pays for a plan being defended and a retainer pays for value arriving. The delivery engagements are retainer-shaped. The team commits to a measurable amount of value every month and reports against it, and either side can end the arrangement on 30 days' written notice, so your protection is a monthly exit rather than a payment schedule to argue over. The two ways in are the exception and are genuinely fixed price, the £44,000 AI Readiness Audit and the £20k–£55k Agentic Proof of Concept, because both end on a date with a defined deliverable and the scope risk sits with us.

Can you deliver something useful in a week?

Not usefully, and we say plainly that a one-week quick fix is not what we sell, because a week is long enough to demo something and far too short to change how anyone works. The smallest real thing we sell is an Agentic Proof of Concept, £20k–£55k fixed over two to four weeks, which builds a working system against one live workflow rather than a demo assembled outside your systems. The AI Readiness Audit runs four weeks at £44,000 fixed and ends in working prototypes against your own data. If a result inside a week is genuinely the requirement, we are the wrong call and will say so.

Are VAT and travel costs on top of your published prices?

Yes, and that is the whole list. Every published figure, day rate and engagement price alike, is exclusive of VAT, and expenses are pre-agreed before they are incurred and charged at cost rather than marked up. There is no management fee, no licence, no seat count and no annual uplift hidden underneath, because every price derives from three published day rates at twenty billable days a month and you can check the arithmetic yourself. Where travel is going to be material, weeks on a site well away from London for instance, we agree it as part of the scope rather than surfacing it later.

Do we need to free up our own engineers during the build?

Yes, and it is the single biggest variable you control. Your engineers pair with ours for the whole build rather than for a handover fortnight at the end, so the people you nominate are working on the real system while it is being built, and the transfer is measured rather than assumed. If nobody can be freed up you still get the delivery, but the capability leaves when we do, which is the one outcome the model exists to prevent. Agreeing who is being freed up at kickoff is a better conversation than discovering in month five that nobody was.

Can we see the engineering standards your engineers build to?

Yes, before you hire anyone. The standard is 72 open-source rules with stable identifiers, RFC 2119 severities and the rationale for each, published as an engineering handbook on GitHub and written to be enforced by an agent rather than remembered by a human. It is what our engineers build to inside your repositories, so your own reviewers can hold the work against a public document rather than a supplier's private conventions. The method above it, The Tenhaw Way, is published in full and free to adopt without hiring us.

How can a team of three change the way thousands of people work?

It cannot on its own, and it is not designed to. Two or three senior people carry the design, the build and the adoption, but the change itself is carried by your own managers and engineers, which is why the decision rights move inside your management structure rather than sitting with a supplier, and why adoption is somebody's named job and gets measured rather than hoped for. The team does not grow as the programme does. If what you need is hundreds of people mobilised across a dozen countries next quarter, a large consultancy is the right call and we will say so on the first call.

How do you know whether people are actually using what you build?

Somebody owns the number and reports it every month. On a build team the adoption lead owns the part that usually fails, getting people to work the new way, and adoption is measured against a baseline taken from your own systems before the change rather than inferred from licence counts or training completions. Usage that does not move is treated as a delivery problem rather than a people problem, which usually means the workflow was redesigned around the agent on paper but not in the roles, the handoffs and the targets people are actually judged on. That is fixable while we are still in the building.

Is Tenhaw credible for a group-wide AI programme?

Judge it on the scale James Rooney has already worked at, and on how cheaply you can stop. He co-led the design and piloting of HSBC Global Payment Solutions' target operating model for 500 teams and a $450 million budget, due for global rollout in 2026, and advised 150+ teams against a $102 million budget at HSBC. The agentic evidence is younger and labelled as such, a two-week proof of concept inside a live London specialty insurance business, now being productionised. The £44,000 audit runs four weeks and stands alone, so the first commitment is small. If your constraint is coverage, a dozen workstreams wanting people at once, a larger firm sells that better.

Who should not hire Tenhaw?

Three buyers, and better said now than in month two. If you want licences procured and a tenancy configured with nothing else changed, your licensing partner will do that faster and for less. If the plan is already written and you want hands to work through it, hire contractors directly and keep the margin, because what we sell is a directed team of two or three that owns the outcome. And if you want a supplier to run the system for you for years, buy a managed service, because our exit date is agreed at kickoff and recruiting your permanent team is a stated deliverable. For those three jobs, the alternative is the better buy.

How can we verify Tenhaw's track record independently?

Start with the twelve case studies, because each one states its own evidence basis. They say whether the work was Tenhaw's or a role James Rooney held inside the organisation, as the three HSBC studies and the Discovery+ launch were, whether a number was measured, projected or a scope figure, and whether it reached production or stopped at a pilot. Nine of the ten organisations behind them are named, so anyone in your network who was in the room can be asked without us in the middle. The exception is the current agentic engagement, confidential at the client's request and written up as a proof of concept rather than offered as a reference call.

What are we actually buying when we hire Tenhaw?

Two or three senior seats, decision rights that sit inside your own management structure, and terms you can hold us to. A build team is three practitioners at £70k–£85k a month and a design pair is two at £35k–£55k, both derived from published day rates at twenty billable days a month. Partner oversight from James Rooney sits inside that fee rather than as an account-management layer on top, and the fee is flat rather than billed against timesheets. Each month carries a value target in currency, and a month that moves none of it is reported as a failed month. A larger firm's fee buys coverage and brand safety instead; where that is the requirement, buy that.

Is Tenhaw a real registered company we can contract with?

Yes. Tenhaw LTD is registered in England and Wales, company number 12735685, incorporated 10 July 2020, VAT registered and based in London, with the register entry linked from the contact page, so you contract with a UK entity and are invoiced in sterling. Every engagement runs under a signed Statement of Work, with a Master Services Agreement where your legal team needs one, and the contract and data protection documents are standing templates rather than things drafted per deal. The commercial terms are published rather than negotiated late: retainers run on 30 days' written notice either way, the exit date is agreed at kickoff, and you own all work product, documentation and code produced up to the point of exit.

What is agentic AI?

Agentic AI is software in which a model plans and acts over several steps towards a goal, calling tools and adapting to what comes back rather than answering a single prompt. Tenhaw embeds teams of two or three senior people to design and build those systems inside a client's own estate, and publishes its method, The Tenhaw Way, in full. Inside a large organisation the model is rarely the hard part. The operating model around it is: who owns the decisions the system now makes, what it is permitted to touch, how autonomous it is allowed to be, and how a wrong call gets caught.

What is an AI agent?

An AI agent is a system that pursues a goal by choosing its own sequence of steps and using tools to carry them out, checking each result before deciding what to do next. Tenhaw's forward-deployed engineers build them inside the client's own repositories, to a 72-rule open-source engineering handbook published on GitHub. A chatbot answers questions; an agent acts on systems of record. Robotic process automation follows a fixed script and breaks when the form changes; an agent reasons about the change. To run safely in a business it needs four things beyond the model: tools with scoped permissions, memory of what it has already done, evaluation against known-good cases, and a named human escalation path.

Do we pay in advance, and when are your invoices due?

Retainers in advance, fixed-price work against milestones, and thirty days to pay. Tenhaw's published terms set out all three: retainer engagements such as an Agentic Design Team at £35,000–£55,000 a month are invoiced monthly in advance, fixed-price engagements such as the £44,000 AI Readiness Audit are invoiced against agreed milestones, and invoices are payable within 30 days. Fees are set out in the Statement of Work rather than in a separate schedule, so what you sign and what you are invoiced against are the same document. Which milestones a fixed-price engagement bills against is settled in that document, so they are worth agreeing alongside the scope rather than after it.

How do scope changes get agreed once the work has started?

In writing, before the additional work starts. A Tenhaw fixed-price fee does not change unless you request a change of scope. The £44,000 AI Readiness Audit and the £20,000–£55,000 Agentic Proof of Concept fix the deliverable as well as the number, and details such as how many prototype workflows get built are settled before kickoff rather than argued in week three. On a monthly retainer the team does not grow, so a new priority is traded against an existing one inside the same monthly value commitment. What a month can absorb without dropping something depends on what you already asked for that month, so the trade is made with your sponsor rather than quietly.

What does the executive sponsor actually have to do?

Nominate one, empower them, and expect them to decide things, because Tenhaw's terms make that your side of the engagement rather than a courtesy. The sponsor does three jobs. They clear timely access to the people, systems, data and decision-makers identified in the Statement of Work, and where a delay there affects the timeline we flag it in writing at the time rather than at the end. They make the calls when decision rights move, once an agent takes part of the work. And they take the monthly report of value committed against value delivered, including any month reported as a failed month. How much of their week that takes depends on how contested those decisions already are.

Can we pause an engagement if our budget is frozen?

Tenhaw publishes no pause rate, so a retainer either runs or it stops. Retainers are invoiced monthly in advance and end on thirty days' written notice from either side, so a freeze means notice now and nothing invoiced beyond it rather than a holding fee for people who are not working. A fixed-price engagement also ends on written notice, with fees payable for work performed and committed costs incurred to that point. The code and documentation are already in your own repositories, so stopping is cheap by design. What a restart costs is mostly the context your own people were holding, which is why the pairing during the build matters more here than the notice clause does.

Can we hire one of your people when the engagement ends?

Ask first, because Tenhaw's published terms carry a mutual non-solicitation clause. During an engagement and for six months afterwards, neither party will knowingly solicit the other's personnel who were directly involved, except through a general public advertisement not targeted at them. It runs both ways, so your people are covered on the same basis as ours. Worth knowing that recruiting your own permanent team is a stated deliverable of the retainer and programme engagements, so the intended destination is your people in post rather than ours. Which roles you actually need to recruit into is an output of the operating model work rather than something that clause settles.

Is the value you commit to each month contractual?

The warranty and the commitment are different instruments, and Tenhaw publishes both. The contract warrants that services are performed with reasonable skill and care by suitably qualified personnel, and stops short of warranting a specific business outcome unless an outcome-linked fee is expressly defined in your Statement of Work, which the terms allow for. Liability is capped at the figure named in that document. The monthly value target sits outside the warranty, a reported commitment you judge month by month, backed by thirty days' notice either way rather than by a damages claim. Whether an outcome-linked fee fits depends on whether the value lands inside a period both sides can measure.
