Fractional AI & automation leadership · for UK founders & operators

Build the AI.
Run the business.

Sitting on AI pilots that never shipped? I'm the operator-engineer who finds the one system worth building, puts it into production, and proves it moved the P&L.

I'm an engineer.
The unusual part is the range.

I build the production AI a business runs on, and I run the business it's built for. Most engineers optimise the system in front of them. I get to choose which system is worth building, because I'm also the one reading the P&L it feeds.

No translation layer

Every other hire is a handoff. Strategy passes to a PM, who passes to an engineer, who passes back something nobody measured against the P&L. I'm all of those people. One head decides which system is worth building, builds it, and owns whether the number moved. Nothing gets lost in translation, because there's no translation.

The problems I close

The things founders actually say to me, and how I fix each one. Hover or tap a card.

What I do

Two sides of the same job. I build it, then I run it.

Build

AI & engineering

Production AI, not demos. And I prove it works.

  • Production LLM / RAG systems & AI agents
  • Workflow automation & systems integration
  • Full-stack: TypeScript, Python, Postgres, Cloudflare
  • Evaluation & governance: evals, grounding, guardrails
Run

Business & operations

I carry the number, not just the code.

  • Budgeting, forecasting & P&L / board reporting
  • Executive & strategic decisions: growth, M&A, incentives
  • Operations leadership & process design
  • Team leadership & cross-functional delivery
A dark, minimal command-centre workspace

One operator. The whole stack.

I run the business and build the AI it depends on, from the same desk.

How I move the numbers

I think in the numbers that run a business, and build the AI that moves each one. Leads → conversion → value → margin → profit.

Leads
AI-assisted SEO, content and multi-channel attribution, so spend goes where demand actually comes from.

Conversion

Anatomy of one system

Depth isn't ten projects named. It's one, shown completely.

01 · Diagnosis

The retrieval engine behind day-to-day operations was nearly blind: about 0.05 recall. It didn't need a bigger model. It needed someone to measure it and admit it was failing.

02 · Decision

So I rebuilt retrieval as a hybrid system (vector plus keyword, with reranking) and engineered it to trustworthy, not just plausible. The model was the easy part; the measurement was the job.

03 · Verification

Recall@5 went from ~0.05 to ~0.85 on a hand-labelled golden set, now regression-gated in CI, with a human-in-the-loop critic that refuses to auto-trust new facts. Under board review and external audit, that's not optional; it's the build.

Shipping under scrutiny

I run production AI where wrong outputs carry real financial and legal weight, under board review and external audit. Governance isn't a slide; it's how I already work.

Eval gates

Nothing ships that regresses

Every prompt or model change runs against a golden set; CI aborts on a regression before it reaches anyone.

Grounding

Answers tied to sources

Responses cite the source records they came from, not the model's memory, so they're checkable.

Human-in-the-loop

People sign off the big calls

The system flags; a person approves anything consequential. Every automated decision is logged and traceable after the fact.

Selected systems

Production systems in daily use. Figures banded for confidentiality.

AI Platform · built hands-on

A multi-step LLM knowledge platform

An organisation-wide retrieval system that turns scattered business knowledge into grounded, cited answers: Postgres + pgvector, hybrid retrieval and reranking, an automated eval harness and a human-in-the-loop critic gating what's trusted.

Your first 90 days

What hiring me actually buys: a diagnosis, a shipped system, and a number that moved.

Days 1-30 · Find the gap

I read the numbers before I touch the stack. Where's the money leaking, and which single lever moves profit most? You get a diagnosis of the binding constraint, not a tool wishlist.

Days 31-60 · Ship against the leak

One production system, built at that lever and measured against a baseline: the first automation live and real hours handed back to the team.

Days 61-90 · Make it govern itself

Evals, guardrails and a repeatable cadence, so it keeps working after I stop watching it: a measurable quality number on every change, not a demo that quietly rots.

The 2-week AI profit lever

I audit your stack and your P&L and hand you the one system worth building first, fully spec'd and costed. Fixed fee. You keep the roadmap whether or not we work together after.

A written diagnosis of the one constraint holding you back
A costed build spec for the first system worth shipping
An ROI / payback estimate against a real baseline
A clear go / no-go, delivered two weeks from kickoff
If the diagnostic doesn't surface a system worth building, you don't pay. And on any build after: one shipped, P&L-measured system within 90 days, or we part ways, no question.

Questions founders ask

Will this work in a business you don't already run?
Yes. That's exactly what the 2-week diagnostic is for: to learn an unfamiliar operation fast. I read the P&L, find the binding constraint, ship at one lever, and measure it. The method is business-agnostic, and the fixed fee de-risks the learning.
What does it cost?
The diagnostic is a fixed fee. I'll share the exact figure on the call. It's deliberately priced to cost less than one stalled pilot or one wrong senior hire. Any build after runs on a simple monthly retainer, scaled to scope.
Isn't a smaller services business too small, or not technical enough?
That's the sweet spot. You don't need an AI department. You need one lever found and shipped. Smaller, ops-heavy businesses are exactly where a single well-chosen system moves the number fastest.
You clearly run a company, so are you actually available? Any conflict?
I take on a small number of fractional engagements. Clean hands, no conflict, and everything is documented and handed to your team, with no lock-in and no single point of failure.
We've been burned by consultants. How is this different?
You get a shipped, P&L-measured system, not a slide deck. It's a fixed fee, and you keep the costed roadmap whether or not we work together after.
Self-taught: can I trust the depth?
Everything I've built has run in production for years, under external audit and monthly board review, not coursework. And the eval harness behind it is public: github.com/CharlieHulme/rag-eval-harness.

How I work

One loop, owned end to end: decision to P&L.

Decide Spec Build Eval Ship Measure the P&L
01

Evals, not vibes

Golden-set evals, regression checks and grounding gates: reliability is measured, not assumed.

02

Tied to the P&L

Every build starts from the business outcome and has a number it's meant to move, and I own whether it moved.

03

Systems over heroics

Owner-dependent → system-led: documented processes, governance and automation so nothing depends on one person.

Don't get left behind

The cost isn't the AI. It's standing still while your competitors compound.

Every quarter, the businesses that adopt this get a little faster, a little cheaper, a little harder to beat. The real risk isn't a failed AI project. It's the efficiency gap that opens when they move and you don't. I close that gap, and keep it closed.

Charlie built and runs the AI and systems our business depends on: instant quoting, forecasting, and the board reporting they feed. He's the rare person who can ship the engineering and own the number it moves. Genuinely transformative for how we operate.

Let's build something that moves the number.
