Proof
What a senior lead and AI actually ship.
Every figure below is counted directly from each codebase and its git history by our measure tool: production code, tests, pages, AI capabilities, commit cadence. Client names are withheld; the engineering is not.
PropTech · Client engagement · Senior lead + AI
A market-intelligence platform for letting agents
A public directory and multi-source data engine: it ingests and reconciles property listings across multiple portals, enriches them against company, EPC and registration data, and grades them with AI. A public site, a data pipeline, and an AI proof-of-concept, delivered end to end.
A traditional team is estimated at £241k-270k for the counted scope. Delivered in 68 working days by a senior lead directing AI, as a deliberately subsidised founding engagement, priced outside our standard band.

Scope for money
Two products built with the same model. Each benchmark is an estimate of a traditional team's cost for the counted scope, from sourced per-component market rates; the range reflects per-row confidence. Set against our published fixed-price ranges, that is typically 4-6 times our price for the same scope. For ventures we believe in, we can share in the upside instead of charging full price. Price the days at your own senior day rate; the arithmetic is yours.
Cyber security · SaaS · Senior lead + AI
A cyber-security guidance and posture platform
A multi-tenant SaaS with RAG-grounded AI security guidance and automated risk suggestions across a large application surface.
£509k-£566k
traditional-team benchmark for the counted scope

Recursive legal-issue decomposition with structured tool use, and case-law retrieval grounded in vector embeddings.

How this is possible
A senior lead directing AI, with specialists pulled in where scope needs them, produces what used to take a coordinated department.
- AI writes the code, tests and documentation. The lead directs and reviews, applying 20+ years of engineering judgment to every decision.
- Specialists join for the work that needs them, design, security, data, under the same single accountability.
- Builds start on infrastructure patterns already proven in production, so work moves on day one.
- Fixed price against a signed done-test, with the delivery risk on us.
How we measure
The scale figures (code, tests, pages, AI capabilities, commits, cadence, working days) are counted directly from each project's git history and infrastructure by our measure tool. Nothing is estimated.
The traditional-team benchmark is an estimate of a traditional team's cost for the counted scope, from sourced per-component market rates; the range reflects per-row confidence. Set against our published fixed-price ranges, that is typically 4-6 times our price for the same scope. For ventures we believe in, we can share in the upside instead of charging full price.It is a benchmark for the counted scope, not a record of anyone's invoice.
Working days are git-counted; days spent across multiple projects are counted in full against each, so correcting the overlap only strengthens the comparison.
AI API spend, third-party vendor spend, and documentation effort are tracked separately and are not included in these figures.
