Proof, not pitch

We have already done the hard part.

Twelve engagements across the UK, Europe and further out. Two where the work itself was AI or agentic, and ten where it was delivery, PMO and operating-model work inside organisations most consultancies find impossible. We think the second group is why the first one worked.

Read these at the scope we held. The budgets were in scope of the roles held rather than governed by us, the 500-team operating model was designed and piloted with rollout due in 2026, and the 1.5M hours a year is a projection from a proof of concept.

How to read this page

Twelve engagements, two different kinds of evidence

Two are AI engagements and ten are delivery work. The split is drawn here, before the cards, because it decides what each one is evidence of.

Read together, the two halves are one capability. The delivery side includes the co-design and pilot of a 500-team operating model at HSBC; the agentic side is working proofs of concept built inside live regulated estates. AI-native organisation design, the structure, roles, decision rights and governance rebuilt around agents, is those two disciplines run by the same people, and the engagement that sells the combination is the Agentic Design Team.

Every engagement also has a page of its own. Each one narrows the caveats to that single piece of work, sets out what a UK regulator expects of an AI programme in that sector, and uses the words buyers arrive with: a fractional head of AI, an interim AI programme director, an AI delivery partner willing to govern a programme somebody else is building. If you are shortlisting an AI consultancy in the UK for agentic work, those are the pages to read sceptically.

The agentic and AI work

Engagements where AI was the deliverable rather than the lens. Both are proofs of concept.

A working proof of concept in two weeks: PDFs in, business intelligence out on Azure, covering ground that had previously taken this business roughly twelve months. We pair-programmed the entire fortnight with one of the client's own engineers, who ended it saying they were 70% confident they could run the process without us. Month one was the audit that pulled us across the whole programme; month two was this build.

The challenge

A specialty insurance business was running a complex multi-workstream programme with delivery stalling in the gaps between product, engineering and platform. Data quality issues were blocking development and testing, a security gate was approaching with no coordination owner, delivery tooling was split across Azure DevOps boards and GitHub, and the leadership team wanted an AI strategy that amounted to more than a set of tool licences. The immediate need was momentum; the underlying need was a different way of building.

What we did

Month one was an audit, and it took us across far more of the programme than a readout exercise would have. We took ownership of whatever was actually blocking delivery: unblocking the data issues holding up development and testing, supporting disaster-recovery failover planning and release governance, and leading the migration from Azure DevOps boards to a GitHub-based delivery model with agent-assisted workflows. In parallel, on the operating-model workstream, we contributed to the workshops shaping product vision, data strategy and the AI operating model, and produced the structured outputs defining MVP focus, data foundations and AI strategy. The value of doing it that way is that by the end of the month we understood the estate from the inside rather than from a survey.

Month two went after the capability the business had been circling for roughly a year: getting information out of PDFs and turning it into business intelligence. We ran our AI-engineering-first method. Every requirement (PDFs, diagrams, images) became structured markdown, AI built a knowledge map across the corpus, and a gap-and-contradiction pass surfaced ambiguities the business had not realised were ambiguous, before a line of code was written. Those went back to the subject-matter experts and were resolved in conversation rather than in rework.

Only then did the build start, from a blank repository on Azure, with high-level prompts against the whole requirement set and a security review roughly every fifth prompt. This was greenfield. It replaced work that had stalled rather than changing a running system with existing behaviour to preserve, and the two-week figure should be read in that context. The pipeline itself is set out stage by stage below.

The entire fortnight was pair-programmed with one of the client’s own engineers, because a proof of concept nobody internal can reproduce is a demonstration rather than a capability.

The pipeline, stage by stage
  1. 1
    Extract to markdownEvery source document is converted to markdown before anything else happens, so what the model actually read stays inspectable by a human rather than disappearing into an embedding.
  2. 2
    Narrow to the key fieldsThe markdown is reduced to the fields the business needs, rather than carrying whole documents forward and paying for them at every later step.
  3. 3
    NormaliseFields are normalised into consistent shapes and units, so downstream logic compares like with like instead of guessing.
  4. 4
    Enrich against third-party APIsRecords are enriched from external sources, and each enrichment carries the provenance of the source it came from.
  5. 5
    Add semantic context and thematic groupingRelated records are grouped and given the context a person would otherwise add by hand when reading them side by side.
  6. 6
    Apply business logicThe client's own rules run over the enriched record. This is the layer that is theirs, not ours, and it is the layer that changes most often.
  7. 7
    Land in the dashboardOutput lands in an internal dashboard the business already uses, rather than in a tool that only exists while we are there.
Confidence score, as an input to routing
  • Source provenance. How much the source of a given enrichment is worth trusting.
  • Model certainty. What the model itself reports about the extraction or the match.
  • Search cross-check. An independent search-based check against the value that was produced.

Those three produce a confidence score on the record, and the score is an input to routing rather than a display value. Review is routed by confidence and consequence together, so a low-confidence field on a high-consequence record reaches a human first and a high-confidence field on a low-consequence one does not generate work. That is a routing rule, not an assurance framework, and it has not been through a regulator or an audit.

The outcome

In two weeks the proof of concept was working: PDFs in, structured and enriched data out, business intelligence on a dashboard the business could use, covering ground that had previously taken roughly twelve months. A separate AI data-quality proof of concept on Azure OpenAI demonstrated that entity-resolution output could be validated and scored automatically, with human review prioritised rather than queued.

The number we care about most is the softest one. At the end of the fortnight we asked the client engineer who had paired on the whole build how confident they were that they could follow the process and deliver the next outcome without us. They said 70%, and 70% after two weeks is the difference between having bought a proof of concept and having started to acquire a capability.

The two-week build is a proof of concept, not a production deployment. Month three stands up an adjacent agent-led engineering team to productionise it against the organisation’s security standards, on a four-to-six week target.

What we cannot publish, and what we will show you on a call

The architecture in detail, the model and platform choices, the prompt and review approach, and the working history of the fortnight sit under client confidentiality, alongside the client's name. You should expect the same treatment of your name and your estate if you engage us.

Why we think it carries over

What transfers is the whole shape of the engagement: one senior person accountable from month one, the operating-model outputs produced alongside the build, a monthly cadence with something real at the end of each month, and a handover built into the build rather than bolted onto the end of it. What does not transfer yet is production. This is a working proof of concept built inside the client's regulated estate, month three is productionising it against the client's security standards, and the result will be published here, dated, when it lands.

PoC
The challenge

Across HSBC, millions of hours of calls and meetings were captured but never analysed. Insight about customers, inefficiency, and risk was buried in voice data while manual note-taking drained staff time. The task was to turn that data into usable intelligence with privacy, accuracy, and scale intact.

What we did

Joining the Innovation Portfolio to lead an AI-led Voice Insights platform, James translated business problems into deliverable AI capability, combining natural language processing, sentiment analysis, and entity recognition. We built prototypes that auto-generated meeting summaries, detected emerging themes, and surfaced real-time dashboards, while coordinating innovation, operations, and risk for adoption readiness.

The outcome

The proof of concept showed potential to remove 1.5M+ hours of manual administration annually and proved voice data could become a new source of business intelligence, shaping the bank's strategic direction on AI platforms.

Why we think it carries over

What transfers is the AI engineering itself: natural language processing, sentiment analysis and entity recognition applied to enterprise voice data inside a regulated bank, with innovation, operations and risk in the room from the start. What does not transfer is production. It reached proof of concept, the 1.5M hours a year is a projection rather than a saving anyone has banked, and nobody has run this at scale.

Before you count the twelve

What this page does not claim

Every one of these is in the engagements themselves. Collected here so nobody has to find them, and so nothing on this page is a surprise to your analyst.

  1. 01

    Ten of the twelve are not AI work.

    They are delivery, PMO and operating-model engagements: story points, forecasting, portfolio governance, agile ceremonies, workflow design. We group them separately below rather than counting them towards an agentic track record.

  2. 02

    Nothing agentic is in production yet.

    The specialty insurance build is a working proof of concept, and month three stands up an agent-led engineering team to productionise it against the client's security standards. The HSBC Voice Insights platform was a proof of concept, and its 1.5M hours a year is a projection rather than a measured saving.

  3. 03

    The HSBC operating model has not been rolled out.

    It was designed, piloted with selected teams and validated against real feedback. Global rollout across the 500 teams is due in 2026.

  4. 04

    The 70% is one engineer's own estimate.

    It is what the client engineer who pair-programmed the build said when we asked how confident they were of running the process without us: self-reported, after two weeks, not a benchmark. We report it because handover is the measure we care about most.

  5. 05

    Some of this was James, personally.

    Where an engagement was held as an individual role rather than delivered by a Tenhaw team, the narrative says James, not we.

  6. 06

    We will ask for a reference, and tell you if it is declined.

    Before you sign, we will go to the client behind any engagement on this page and ask them for a reference call. Some will say yes and some will not, and the confidential one may well not. If they decline, we will tell you.

If that list rules us out, it should rule us out now rather than in month three.

Group two of two · 10 engagements

The delivery and operating-model work

A decade of Scrum Master, agile coaching, PMO and operating-model engagements. None of these were AI projects. They are here because an agentic operating model is installed on top of exactly this: visible work, measured throughput, clear ownership and decisions made on data.

spun out as a standalone leader
First Mode
The challenge

Anglo American formed an ambitious internal startup to prove mining operations could run on hydrogen-powered trucks with hydrogen produced on-site. It needed a digital framework that would hold up under scrutiny, decisions made on data, and aligned teams across three continents, with no precedent to copy from.

What we did

Tenhaw set up and ran digital teams specialising in Data, Simulation, and DevOps. We installed a lightweight, scalable agile blueprint so high-calibre specialists (Cambridge PhDs among them) could onboard fast and stay aligned across the UK, Australia, and the USA. Delivery ran async by necessity, throughput data fed Monte Carlo simulations, and outcome-based milestones replaced traditional project plans so the largest risks were attacked first.

The outcome

The work underpinned a £40bn business case and produced the decisive insight that hydrogen trucks were not yet cost-competitive, letting leadership invest with eyes open. The internal startup spun out as First Mode, now a leader in heavy-industry decarbonisation.

Why we think it carries over

What transfers is standing up a delivery function with no precedent and forecasting from throughput rather than opinion. What does not transfer is anything about agents. There were none on this engagement.

The challenge

Discovery+ had a hard launch date announced by the CEO and six teams that needed to redesign and merge content. The visual rebrand team Tenhaw was asked to run was badly overloaded relative to the time available.

What we did

We moved delivery onto a data-driven footing, recalibrating Story Points to reflect actual capacity after completion rather than optimistic estimates. Across three sprints we presented Head of Delivery with Happy, Normal, and Sad path forecasts, made the probability of missing the date undeniable, and issued daily recommendations to lift speed and quality.

The outcome

Discovery+ and Eurosport got the clarity to manage delivery under real constraints and hit the launch. By the end of the engagement both teams could run those forecasting and tracking practices autonomously.

Why we think it carries over

Probabilistic forecasting and confidence intervals are exactly what leadership needs to govern an agentic transformation: not a single guessed date, but a range you can plan and intervene against.

predictability extended across functions
Dev + security + support
The challenge

Yondr's global digital teams delivered inconsistently, so the business could not plan beyond a quarter. That unpredictability was most damaging in the UK and USA, where reliable delivery was critical to scaling data centre operations.

What we did

We introduced accurate Story Point estimation, adjusted post-completion to reflect real capacity, and embedded the agile ceremonies that were missing: retrospectives, planning, and active backlog management. The work ran remotely across three regions, reinforced with on-site workshops.

The outcome

Within three months development teams were producing consistent output every sprint. By six months that predictability had reached support and security teams, and the business could finally plan holistically.

Why we think it carries over

What transfers is the baseline. You cannot state an automation improvement in a system whose human throughput nobody can currently state to within a factor of two, and this is the work of getting to that number. What does not transfer is any AI content: there were no models and no agents here, and predictability is a precondition for automation rather than evidence of it.

Tech debt
The challenge

Greggs launched a mobile app so customers could order and earn rewards, but the rushed setup of technical ways of working created friction with Marketing and other departments. They needed Scrum Master support for two squads plus broader agile coaching across the business.

What we did

We refined Story Points for capacity-based tracking, coached Product on data-driven prioritisation, and ran prioritisation workshops and alignment sessions that taught non-technical teams how agile actually works. We used data to prove the payback of addressing tech debt.

The outcome

Delivery became predictable, confidence in the technical department recovered, and prioritisation conversations became realistic and focused. The data showing tech debt accelerated timelines strengthened collaboration across departments.

Why we think it carries over

Cross-functional trust and a shared, data-backed language for value are prerequisites for agentic change. Agents amplify whatever operating culture they land in, so the culture has to be sound first.

PMO
The challenge

Tecknuovo, a consultancy, needed a centralised Portfolio Management Office to oversee 19 diverse projects, including critical public-sector engagements, and wanted its junior staff upskilled in best practice.

What we did

We built a PMO function from the ground up, implemented portfolio frameworks for tracking and managing delivery, and provided hands-on coaching to junior team members in portfolio management and agile delivery while overseeing the live portfolio.

The outcome

Tecknuovo gained a fully functional PMO with real visibility and control, a markedly more capable junior delivery team, and reinforced credibility on high-profile public-sector work.

Why we think it carries over

What transfers is the function itself: a standing register of what is being built, who owns it, what it was permitted to do and what happened when it was reviewed, which is where model governance ends up living in most organisations. What does not transfer is any AI governance claim. Nothing in this portfolio was a model, and we have never run an AI or model register in production.

The challenge

After Colart merged its Global Marketing, Development, and Business Intelligence teams, the new Digital Team lacked alignment, communication channels, and consistent delivery, stalling key transformation work including a new e-commerce site.

What we did

We designed agile processes for a cross-functional team, aligned Jira workflows to how the business actually worked, established clear communication channels, matured the backlog to cut downtime, used data to guide prioritisation, and escalated critical issues to senior leadership when needed.

The outcome

The Digital Team became cohesive and predictable, transformation work progressed consistently, and the e-commerce website shipped successfully.

Why we think it carries over

What transfers is that an agent needs exactly what this merged team needed: an unambiguous definition of a piece of work, a state model to move it through, and somewhere to escalate when it cannot. What does not transfer is the technology. This was process, workflow and backlog design, and there is no AI anywhere in the deliverable.

The challenge

Salmon was re-platforming YNAP's e-commerce solution to IBM WebSphere Commerce. The scale demanded tight coordination across five agile teams against strict client deadlines, while managing staff transitions and operational logistics.

What we did

We ran a dual Scrum Master and PMO model: facilitating agile delivery across five teams, managing onboarding logistics and equipment, streamlining communication between the client PMO and internal teams, and maintaining transparency through weekly reporting and travel coordination.

The outcome

The programme progressed efficiently, teams met client deadlines with a high standard of collaboration, and tight operational processes produced a well-executed project and strong client satisfaction.

Why we think it carries over

Multi-team coordination with a single source of truth is the same problem agentic transformation faces at scale: many actors, shared dependencies, one operating rhythm everyone trusts.

Days, not weeks
The challenge

HSBC's CIO and ExCo had no shared mechanism to track and manage critical strategic initiatives. Visibility was poor, milestones slipped, blockers persisted without escalation, and confidence in the function's ability to deliver had eroded across 150+ teams and a $102M budget.

What we did

Operating effectively as a Scrum Master for the executive team, James designed a lightweight governance model around a live Kanban of all work, planned initiatives, and dependencies. He introduced daily executive stand-ups, removed obstacles directly, and established a review and planning cadence that created a common language across technology, operations, and transformation.

The outcome

Executive alignment and decision speed improved sharply. Annual planning completed ahead of schedule for the first time in years, C-suite visibility increased, delivery cadence stabilised, and blockers that once took weeks were routinely cleared in days.

Why we think it carries over

Agentic transformation lives or dies in the executive room. This is exactly the operating discipline an Embedded Agentic Lead installs at the top: visible work, fast decisions, and accountability that holds.

The challenge

HSBC's Global Payment Solutions division had no consistent operating model across 500 teams and a $450M budget. Every region had its own processes, creating fragmented delivery, unclear ownership, and unpredictable outcomes with little leadership visibility.

What we did

Brought in as Delivery Lead, James co-led the design, piloting, and refinement of a new target operating model with select GPS teams: standardised roles, governance and reporting; agile practices tailored for product delivery at scale; and metrics and dashboards for progress, dependencies, and value. The model was tested against real-world feedback with executive alignment throughout.

The outcome

Pilots validated the model, with improved predictability, clear ownership, and faster decisions. Blockers and dependencies surfaced earlier, and the framework is fully designed, tested, and ready for global rollout across all GPS teams in 2026.

Why we think it carries over

What transfers is the operating model work: defining roles, governance, reporting and value metrics once, so the fifty-first team to adopt a capability is cheap rather than a fresh negotiation. What does not transfer is proof at scale. The model was designed, piloted and validated against real feedback, global rollout is due in 2026, and nothing here has been through a rollout yet.

The challenge

Globelynx had long delivery timelines, inconsistent coordination, and little operational insight. Teams could not prioritise effectively, and decisions across Operations, Partnerships, and Client Management lacked actionable data.

What we did

We introduced iterative planning, stand-ups, and retrospectives across 16 client deliveries and one internal change project, coordinated timelines and dependencies, renegotiated supplier engagements to cut cost and improve performance, and continuously collated operational data into trends leadership could act on.

The outcome

Within six months delivery lead times fell by 60%, client satisfaction rose, supplier relationships strengthened, and data-driven insight let teams make sharper strategic decisions, positioning Globelynx for scalable growth.

Why we think it carries over

What transfers is the habit of baselining a process before claiming an improvement to it, and of counting the running cost of a change rather than only the cost of building it. What does not transfer is anything agentic. This was agile delivery, supplier negotiation and operational reporting, with no AI in it at all.
