MVP Development Agency UK
From idea to product
From idea to product
in 8–12 weeks.
We build MVPs for founders, startups, and internal product teams who need to move fast and get it right. Fixed scope, predictable delivery, full code ownership — and engineers who've done this before.
50+ MVPs shipped
10+ years average experience per engineer
Fixed scope, fixed price
Full code ownership from day one
UK-based, global clients
Our approach
An MVP is a product, not a prototype.
A minimum viable product isn't a rough demo or a mockup — it's the smallest version of your product that real users can use to do a real job. It needs to be stable, secure, and maintainable, because you're going to iterate on it. Cutting corners at this stage costs you more in the next.
Every MVP we build is production-grade from day one: tested, documented, and built on infrastructure you can scale. The "minimum" in MVP refers to scope, not quality.
- Discovery sprint to nail scope before a line of code is written
- Web, iOS, Android — or all three, depending on your audience
- Cloud infrastructure set up correctly from the start
- Code review, automated testing, and CI/CD pipeline included
How it works
From first call to shipped product
We follow a repeatable process that keeps scope tight and delivery predictable.
01
Week 1 — Discovery
Define what you're building and why
A focused discovery sprint where we map out your users, their problems, the core user journey, and the smallest set of features that proves the value. We come out with a clear scope document and a realistic timeline and cost estimate.
02
Weeks 2–3 — Design
Design the product, not just the screens
We design the information architecture, user flows, and UI with your target user in mind. The goal is a design you can put in front of real users for feedback before build begins — not a pixel-perfect mockup nobody ever validates.
03
Weeks 4–10 — Build
Build in short, visible iterations
We build in one-week sprints with a working demo available at the end of every sprint. You see progress every week, can reprioritise as you learn, and are never waiting for a big reveal. Infrastructure, testing, and CI/CD are set up in sprint one.
04
Weeks 10–12 — Launch
Ship it and learn from real users
We handle App Store / Play Store submission, production deployment, and any pre-launch hardening. At handover you receive the complete codebase, infrastructure access, documentation, and a recorded walkthrough of the architecture for your team.
What we build
Common MVP types we've shipped
Consumer mobile apps
iOS and Android apps built with React Native or Flutter — with App Store and Play Store submission handled.
AI-powered products
Products with LLM-powered features at the core — built with the evals, guardrails, and cost controls to survive production.
Marketplaces & platforms
Two-sided marketplaces, booking platforms, and products with both supply and demand sides to design for.
Internal tools
Custom dashboards, workflow tools, and internal systems that replace spreadsheets and duct-taped SaaS stacks.
API products & integrations
Developer-facing products, data integrations, and backend platforms designed to power other applications.

Questions
FAQ
How long does MVP development take?
Most MVPs we build ship in 8–12 weeks from the end of the discovery sprint. Simpler products (a focused SaaS tool or internal app) can be faster; products with mobile apps, AI features, or complex user flows take longer. We scope before we commit to a timeline.
Do I need a technical co-founder or CTO?
No. We're comfortable working directly with non-technical founders. Part of our job is to translate business goals into technical decisions and to make sure you understand what's being built and why. Many of our best client relationships are with founders who don't write code.
What do I own at the end?
Everything. Source code, infrastructure configuration, documentation, design files — all transferred to you at handover. No vendor lock-in, no ongoing licensing fees to us, no black boxes. You can take it to any other agency or hire your own team and they'll be able to hit the ground running.
Can you help after launch?
Yes — we offer ongoing support and maintenance plans, and many clients continue with us for the next phase of development after their MVP validates the idea. We're not trying to build something and disappear.
We already have a design / some code / a prototype — can you work with that?
Usually yes. We'll review what you have as part of the discovery sprint and work out what's usable, what needs rethinking, and what we can build on top of. We're not precious about starting from scratch if there's already good work done.
How is this different from using a no-code tool?
No-code tools are great for validating an idea cheaply, and we often recommend them for very early exploration. But they have real limits: performance, customisation, scalability, and the ability to build features that don't fit the tool's model. If you've outgrown no-code, or you know from the start you'll need something more capable, custom development is the right path.
