We rebuild how your organisation works around AI agents.
Anyone can buy AI tools. The hard part is getting thousands of people to work differently around them.
Tenhaw is a UK AI consultancy and AI delivery partner, based in London and working with enterprises across the UK, Europe and the US. We embed forward-deployed operators inside large organisations to redesign the operating model, build the agents, and make the change stick. We advise and we implement, because handing the build to someone else is where most programmes lose a year.








What clients say about the delivery and coaching work
References for delivery transformation and agile coaching, the work Tenhaw has done for a decade. The agentic evidence is in the case studies.
“Tenhaw was able to balance both the needs of the client and the teams psychological safety to consistently deliver on time. Their unique playful approach to teaching agile concepts landed with teams that previously struggled to grasp them. Genuinely a pleasure to work with and would highly recommend for both coaching and delivery work.”

“If you're looking for advice from on how to set up a delivery function from scratch, train your staff and put out all the fires, whilst keeping an infectious, positive attitude throughout - then Tenhaw is your delivery partner!”

“I trust Tenhaw to train, lead, and set direction on how to create tech Agile teams the business is happy with! I love working with people who understand that "Agile" is not a framework, but a mindset of delivering fast, efficient, and without BS.”

“If you're after top-notch Agile Management, Tenhaw are as good as it gets. Not only will they ensure your work is delivered effectively, but they'll also make the process genuinely enjoyable. Listen to Tenhaw - you won't regret it.”

We have already done the hard part.
A decade landing transformation at organisations everyone else finds impossible, plus the agentic engagement running right now. Twelve are written up in full, including where the answer was no.
The labels are exact. The agentic evidence is working proofs of concept: the flagship was built in two weeks inside a live London specialty insurance business, pair-programmed with the client's own engineer, passed its security gate, and is now being productionised.

Why AI transformations stall at exactly the same point.
The technology changes and the organisation does not. Every one of these is an operating-model problem wearing a technology costume.

How we ask to be held to account
You get working software in production every month, not a distant go-live. Each month the team commits to something measurable reaching production and reports against it. A month with nothing in production is reported as a failed month. Hold us to that from month one.
And we build to leave. The software ships to your infrastructure and your repositories. Your permanent people pair-program with ours for the whole build. The exit is contractual, thirty days' notice either way, with all deliverables, documentation and code owned by you on payment.

We have strong opinions.
A decade of landing change at the world's hardest organisations, codified. Three things we are uncompromising about.
Org design is the lever. And we are hands-on with it.
We redesign how the organisation is wired before anyone touches a tool, and we do it embedded alongside your people, not from a deck. Get this wrong and no platform saves you.
- Forward-deployed: in your rooms, your decisions, your org chart
- Roles defined by the decisions they own, not the tickets they move
- Accountability mapped before a single agent is deployed
- Governance that makes agent decisions auditable, not theoretical
- Built to run without us in the room
Predictable delivery beats heroic delivery, every time.
Delivery should be a forecast you can stake a budget on, not a vibe. We are uncompromising about how teams ship.
- Forecast with probabilities, not finger-in-the-air dates
- No SAFe, no sprint theatre, no annual plans that rot by Q2
- Flow and team health measured continuously, acted on early
- Ship value slices, not feature factories
If you cannot price the outcome, you cannot manage it.
Every piece of work earns its place by moving a number the business cares about. Activity is not progress.
- Every initiative carries a measurable business outcome
- Value tracked in currency, on every item, end to end
- Work that will not move a metric is killed before it starts
- Leadership sees return, not a burndown chart

Built by someone who knows how to land change.
I'm James Rooney. I've spent a decade landing delivery transformation across HSBC, Microsoft, Sky, F1, Discovery and Anglo American, advising 150+ teams at HSBC against a $102M budget. The hardest part was never the tools. It was getting people to change how they work. I'm personally accountable for every engagement we run, and I'll tell you on the first call if we're the wrong firm for what you need.
Read the standard before you read the pitch.
Three artefacts, all public. If you are going to send this page to someone who will judge us on how we build, send them these.

Written to be enforced by an AI agent rather than remembered by a human, because a model will happily write code that passes tests and violates every convention your team holds. Free to adopt whether or not you ever hire us.

Thirteen steps, published in full
Every requirement converted to markdown, a knowledge map built across the corpus, then a gaps-and-contradictions pass before a line of code exists. Build at maximum reasoning against the whole requirement set, with a security review roughly every fifth prompt.

The pipeline, stage by stage
PDFs in, business intelligence out, from a blank repository on Azure. Extract to markdown so the output stays inspectable, then narrow, normalise, enrich against third-party APIs and apply business logic. Confidence is scored from source provenance, model certainty and a search cross-check, and routes human review by consequence, not as a queue.

What Tenhaw is
The four answers most buyers want before booking: what we are, whether we advise or build, what it costs, and how we differ from a large consultancy.
What is Tenhaw?
Tenhaw is a UK AI consultancy and AI delivery partner, based in London and registered in England and Wales. It embeds forward-deployed squads of three (an agentic lead, an engineer and an adoption lead) inside large organisations to redesign how they work around AI agents: the operating model, the systems that get built, and the adoption that makes the change stick. Engagements deliver a monthly production increment, not a distant go-live. Tenhaw sells professional services, not software.
Is Tenhaw an AI consultancy or a delivery partner?
Both, and refusing to pick is the point. The consultancy half is diagnostic: a fixed-price Agent-Readiness Audit that establishes where agents create value, what your data estate and platform can actually support, and what evidence your risk function will need. The delivery half is that the same people then build it, inside your estate and your repositories, alongside your engineers. Most AI consultancies stop at the recommendation. An implementation partner usually arrives after somebody else has decided what to build. That gap is where enterprise AI programmes lose a year. Tenhaw is an agentic AI consultancy that ships, and it will equally run a programme other suppliers are building, with no requirement that it builds any of it. It is not a body shop selling undirected engineering capacity by the head. The decade of track record is delivery and transformation; the agentic evidence is a working proof of concept built in two weeks inside a live, regulated London insurance business, now being productionised. The case studies label which is which.
How much does Tenhaw cost?
Tenhaw publishes both its engagement prices and its day rates. Day rates: partner (James Rooney) £1,560, senior practitioner £1,250, associate £950, all excluding VAT. Engagements: Agent-Readiness Audit £30,000–£90,000 fixed; Agentic Proof of Concept £20,000–£55,000 fixed over 2–4 weeks; Agentic Design Team £35,000–£55,000 per month; Agentic Build Team £70,000–£85,000 per month; Programme and Delivery Management £18,000–£35,000 per month. Every engagement price is derived from the rate card at twenty billable days a month, so you can check the arithmetic yourself.
How is Tenhaw different from a large consultancy?
Team shape and accountability. Tenhaw deploys a small number of senior operators who build alongside your people, publishes its prices, commits to a production increment every month and reports against it, and writes a contractual exit date and permanent-team recruitment into the scope. Large consultancies offer scale, multi-domain regulatory depth and brand safety that Tenhaw cannot match. If you need 200 people across twelve countries, they are the right call.
