DiscoverySprint.

Five working days. A written architecture brief, a working spike on the riskiest piece, and a fixed-price proposal you can take to procurement. No discovery-call gauntlet — you pay for senior engineering time, you get senior engineering output.

01 / Day by day

Monday to Friday

MON

Kickoff

45-min call to align on outcomes, constraints, and the shape of the answer you need by Friday.

TUE

Architecture

We draft the system. Data flow, components, integration points, deployment topology.

WED

Spike

We build the riskiest piece — the part you'd be wrong to commit a quote on without proof.

THU

Review

We share the work-in-progress and adjust based on your feedback. Open dialogue, no surprises.

FRI

Delivery

Final brief, prototype, risk register, and a fixed-price proposal for the full build.

03 / Deliverables

What you walk away with

  • Architecture brief

    12–24 pages, written for your CTO
  • Technical spike

    Working code on the riskiest module
  • Risk register

    What we don't know yet, and how to find out
  • Fixed-price proposal

    Milestones, dates, deliverables, total
  • Credit toward full build

    The £4,800 reduces your final invoice
02 / Who it's for

Four kinds of engagements

Custom-scope automotive work

ADAS programs, embedded software, V2X — projects too specific to price by configurator.

Bespoke AI systems

Domain-specific fine-tuning, novel agent architectures, complex retrieval setups.

Replacing legacy systems

Migration audits, modernization roadmaps, brownfield re-architectures.

Enterprise procurement requires a SOW first

Procurement teams that need a written statement-of-work before any commitment.

04 / Common questions

The short version

Is the sprint fee credited if I proceed?

Yes. The full £4,800 reduces the first invoice of the project we scope together. If you don't proceed, you keep the brief and proposal — they're yours.

What if you can't deliver a proposal?

Rare. If we genuinely can't scope it in five days — for example, you discover the problem is fundamentally different mid-sprint — we deliver what we have and refund the unused portion.

Who's the engineer?

One senior person, named upfront. Same person from kickoff to delivery, with the right vertical background for your project.

Can we run the sprint under NDA?

Yes. We sign mutual NDAs before any work. For regulated industries we operate with segregated infrastructure and audit logging.

Sprint spec

One week.
A real plan.

£4,800 paid up front, refunded against the first milestone if you commission the full build. No discovery-call gauntlet — you pay for senior engineering output.
