Ten Tenths Consulting Limited launched a complete production webapp in Lean 4, including passwordless sign-in, SQL migrations, telemetry, LLM assistant panel, MCP endpoint, and IaC deployment to AWS.

Ten Tenths provides technical due diligence targeted at early- to mid-stage startups (up to 50 employees, up to £5m investments, up to £50m valuations). Engagements range from “kicking the tyres” conversations to in-depth investigations lasting 5 days or more. The resulting report will normally cover the full range of software development activities, but the approach can be extensively customised to concentrate on areas of particular concern.
