Ten interventions · two commercial routes
Clear outcomes. Written boundaries. Work you own.
Every engagement begins by defining what must be true at the end. Most work is fixed-price; qualifying product builds can instead use revenue share.
Architecture Review
An evidence-backed review of system boundaries, data ownership, failure modes, scale limits and operating cost.
£12,000↗S2Agentic-Ready Codebase Analysis
Find out whether AI agents can change your code safely: we test repository structure, specification reachability, gate quality and test independence.
£8,000↗S3Depth Audit (is it actually done?)
Independent verification of a claimed-complete build, looking for hollow tests, simulated critical paths and work marked done without evidence.
£6,000↗S4Technical Due Diligence
Technical due diligence for acquirers and investors, connecting architecture to cost-to-serve, key-person risk, licensing, data protection and recovery.
£15,000↗S5Spec Compile & Build Plan
Turn a product idea or existing specification into an execution-ready plan with explicit decisions, dependencies, acceptance checks and coverage evidence.
£10,000↗S6Feature-Complete Product Build
A complete production product, built from the agreed plan and delivered with verification, runbooks and operational handover.
from £60,000↗S7Technical Recovery / Refactor
Stabilise, refactor or replatform a system without stopping delivery by proving behavioural equivalence before switching over.
from £25,000 or £1,400/day↗S8Verification Harness Build
Build a verification harness that generates demanding cases, compares behaviour and uses deliberate faults to prove the tests can fail.
£18,000↗S9Fractional CTO / Architecture Lead
Named product or architecture leadership on a retainer: design authority, hiring standards, board reporting and AI adoption measured against delivery outcomes.
£1,500/day; retainers £6,000 / £11,000 / £20,000 per month for 4 / 8 / 16 days↗S10AI-Native Delivery Enablement
