HowMuchDoesItCosttoBuildanMVPforaUKStartup?

The single biggest lever is scope: how many distinct user-facing flows the MVP needs before it can be tested with real users. A second lever is platform — a web-only MVP is cheaper and faster to ship than native iOS and Android apps built in parallel, and for most early-stage products a single web app (or a Flutter app that covers both mobile platforms from one codebase) is the more capital-efficient starting point.

The third lever is who builds it. London day rates for contract developers commonly run high because of the local cost of living and demand from well-funded scale-ups, and agencies layer account management and multiple specialists on top of that. A senior remote developer working directly with the founder removes both of those cost layers without removing the engineering quality.

For a well-scoped MVP with one core flow, fixed-price work in this range starts from USD 500 and scales with the number of flows and third-party integrations (payments, email, analytics). Hourly billing runs USD 25–45/hr with a 10-hour minimum, which works well for a UK founder who wants to keep adjusting the build as user feedback comes in during a beta.

If your MVP needs to demonstrate something specific to satisfy an investor milestone — a working payment flow, a live data pipeline, a functioning matching algorithm — say so explicitly during scoping. That's the part of the build that actually needs the senior attention; everything else can often be simpler than founders initially assume.

London sits roughly 5 hours 45 minutes behind Kathmandu (4 hours 45 minutes during British Summer Time), which in practice means a solid midday overlap for calls, with build work continuing into the UK evening. For founders juggling fundraising and product simultaneously, that extra runway is often more valuable than a same-timezone hire who can only work 9-to-5 alongside you.

Get a written scope and a fixed-price or capped-hourly agreement before work starts — that document is also useful to show investors that the MVP budget was planned, not guessed at.
