How this works
One AI-native engineer.
The output of a team.
One senior engineer plus AI agents now ships what four engineers used to. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.
The local read
Why this works for London
London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.
Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.
