MVP Development London a technical partner, not an agency queue
London has no shortage of development agencies, and most quote MVPs the same way they quote enterprise projects — long discovery, layered account management, and a day rate that assumes a team of six. For a pre-seed or seed-stage product that structure burns runway on coordination rather than code. I work the opposite way: one senior person across scoping, design and build, so decisions take hours rather than a fortnight of stakeholder alignment.
I'm based in Windsor, about half an hour from Paddington, which means in-person scoping days in central London are straightforward when they earn their keep — kick-off workshops, investor-deck prep, or a whiteboard session when the data model is contested. Everything else runs remotely with twice-weekly demos, so you always see working software rather than a status report.
Most London MVPs I build are B2B SaaS, marketplaces, or internal-ops platforms replacing a spreadsheet that has outgrown itself. Budgets typically land between £25,000 and £60,000 over 8 to 14 weeks, fixed price after a scoping week. You own the repository and the IP from day one, which matters when a due-diligence process starts asking questions.
Everything you need to launch
What London founders usually need built
Three patterns cover most of the MVP work coming out of London right now.
B2B SaaS for a niche you know
Founders leaving finance, legal, property or agency life to productise the workflow they ran manually. Usually £30,000–£55,000.
SaaS MVP developmentMarketplace or matching platform
Two user types, vetting, messaging and payouts. Heavier than it looks — typically £35,000–£80,000 for a credible version one.
Custom web appsInternal ops platform
Replacing spreadsheets and email threads with a real system, often the fastest to fund because the ROI is already measurable. From £15,000.
Custom CRM buildsHow it works
Scoping week
Optional in-person day in London, then a fixed price and a feature list you've agreed to cut.
Design
Prototype of the core journey and admin, signed off before build starts.
Build
6–10 weeks with twice-weekly demo links, so nothing is a surprise at the end.
Launch
Beta cohort, analytics, investor demo environment, then a prioritised version-two backlog.

Frequently asked questions
How much does MVP development cost in London?+
London agencies commonly quote £60,000 to £150,000 for an MVP because of team size and overhead. Working with me, most MVPs land between £25,000 and £60,000 over 8 to 14 weeks, fixed price after a scoping week.
Are you based in London?+
I'm based in Windsor, about 30 minutes from Paddington, and travel into central London for kick-off workshops, scoping days and investor prep. Day-to-day delivery runs remotely with twice-weekly demos.
Can you work alongside our in-house developer?+
Yes. I often build the first version and hand it over to an in-house hire, or work alongside a technical founder who wants to own part of the codebase. Code review, documentation and a walkthrough recording are part of handover.
Do you help with investor materials?+
I build the demo environment investors will actually click through, and can support the product and roadmap sections of a deck with realistic timelines and costs. I don't write the financial model.
What if we need to move fast for a funding deadline?+
Tell me the date in the first call. Sometimes the answer is a tighter scope rather than a faster build — a smaller MVP that works beats a bigger one that half-works in a demo.
Do you sign NDAs?+
Yes, happily, before any detailed discussion of your idea.
