How this works

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships fractional cto that used to need a four-person team. 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 fractional cto is hard in 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.

Hiring one senior leader here is a ~$200K year-one outlay and a 60–90 day search. Our fractional cto engagement starts at $4,000 with a first deploy in Monthly engagement.

FAQ

Common questions about fractional cto in London

How much of your time do we get?

+
Plans typically range 10–30 hours/month depending on scope. We're not your only commitment, but we set a fixed window every week that's yours — same day, same hours.

Is the price really flat?

+
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Can you hire engineers for us?

+
Yes — full hiring loop: writing the JD, sourcing channels (we have a network), screening, technical take-home design, final-round interview. Most CTOs we've helped hire run their first sprint inside a month of starting.

Will you keep coding if we hire a full CTO later?

+
Happy to. Many founders bring on a full-time CTO and keep us as senior IC for 2–3 months while they ramp. No ego — we'll happily report to whoever you hire.

Who owns the code?

+
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
