Clapperton Labs

Applied AI engineering for complex, regulated domains.

We design, build and ship production AI systems — from document intelligence to agentic automation.

01 / What we do

  • Document & data intelligence

    LLM extraction pipelines that turn unstructured documents into accurate, structured data — with accuracy you can measure.

  • Agentic systems

    Agents that detect, diagnose and remediate errors in production workflows, built to act safely inside real business processes.

  • Platform integration

    AI embedded into existing production systems — not greenfield toys. We work inside your stack, your constraints, your compliance.

  • Evaluation & accuracy

    Benchmarks and evals wired into delivery, so every improvement is provable and every regression is caught.

02 / How we work

  1. Prove it small

    Every engagement starts with a scoped pilot against your real data — success criteria agreed up front, so you find out quickly whether the approach holds.

  2. Ship it properly

    Production code inside your existing stack and constraints — reviewed, feature-flagged, reversible. Not a research prototype left at the door.

  3. Measure, then expand

    Benchmarks and evals decide what gets built next. When accuracy moves you can see it move — and when it doesn’t, you find out early.

03 / Data & security

Built for domains where a wrong answer has consequences. These are the defaults on every engagement:

  • No training on your data

    Client data is never used to train models — ours or anyone else’s. Model providers are configured accordingly.

  • Least-privilege access

    We work inside your environments with the minimum access needed — granted on day one, revocable on day one.

  • NDAs as standard

    Confidentiality first. We’re happy to work under your paper or provide ours.

  • Auditable by design

    Changes to AI behaviour are benchmarked and logged, so you can show a regulator what changed, when, and why.

04 / Founder

Founded by Theo Clapperton

Theo is a technical lead and engineering manager who ships production software at national scale: an award-winning mobile healthcare platform, and retail systems running in stores across the UK.

His recent work is in applied AI — building multi-agent LLM systems and guiding responsible AI adoption in regulated healthcare. He has delivered across healthcare, retail, and customs: domains where correctness isn’t optional.

05 / Working with us

How do engagements start?

With a scoped pilot against your real data — fixed deliverables and success criteria agreed up front, so you find out quickly whether the approach works before committing further.

Who owns the work?

You do. Code, prompts, evals and documentation are delivered into your repositories, and IP assigns to you on payment.

Do you work with in-house teams?

Yes — we build inside your stack and your processes, and everything ships with documentation and handover so your team can run it without us.

How do you price?

Fixed, milestone-gated scopes for delivery work — you pay for outcomes, not hours. Advisory work is day-rate.

What if AI isn’t the right answer?

Then we’ll tell you, with the eval results to back it up. The pilot exists to prove or kill the approach cheaply — that’s the point of it.

06 / Contact
