“Can a solo contractor-founder, armed with AI coding tools, ship a tier-one construction back-office platform priced for SMB contractors?”
Construction AI is a UK vertical-SaaS platform for contractors, built by a construction manager (Stephen Mckenna, MCIOB) using AI coding tools over roughly 12 months. It bundles tenders, project management, RAMS, site management, and financials — including UK Construction Act-compliant payment applications and CVR — under one canonical data model exposed via REST API and MCP. There is no evidence of external funding; the company is priced as a self-serve SaaS from £130/month with a BYOK model for the AI assistant (customers bring their own Claude API key, avoiding AI markup).
Construction AI was founded by Stephen Mckenna and is founded in 2024, headquartered in Gerrards Cross, England, UK.
