MVP development in 14 days

We design, build and launch a working MVP in fourteen days at a fixed price. What that includes, what it leaves out, and when you need more than a sprint.

An MVP is the smallest version of your product that does its one job well enough for real users to use it. We design, build, and ship one in fourteen days.

Most UK agencies quote £20,000 to £60,000 and three to four months for an MVP. We work differently, and the difference is not a shortcut. It is scope: we build the one thing your product has to do, and we build it properly.

What you get

Everything below is in every sprint, at either price point.

  • A working iOS and Android appReal native builds, submitted to both stores. Not a wrapped website.
  • User accounts and loginSign up, sign in, password reset, session handling.
  • An admin dashboardSo you can see what is happening without asking us.
  • Push notificationsSet up and working, not a to-do for later.
  • The full source codeYour repository, your accounts, your stores. No licence fees.
  • Store submissionWe handle App Store and Play Store listings, screenshots, and review.
  • 30 days of support after launchWhile your first real users arrive and find the things nobody predicted.

What is not included

How the fourteen days actually run

  1. Day 1

    Kick-off and scope

    We go through your goals, your users, and the one job the app has to do. Everything that is not that job goes on a version-two list.

  2. Days 2 to 3

    Design

    Screens, flows, and the look of the thing. You review and revise until you sign off. Nothing gets coded until you have.

  3. Days 4 to 10

    Build

    Front end, backend, accounts, notifications, admin dashboard. You see working builds as they land rather than a reveal at the end.

  4. Days 11 to 12

    Test and fix

    Real devices, real data, edge cases. This is where most of the unglamorous work happens.

  5. Days 13 to 14

    Submit and launch

    Store listings, screenshots, privacy details, and submission to the App Store and Play Store. Then 30 days of support while your first users arrive.

The part that surprises people is day one. Most of the value in a two-week build comes from deciding what not to build, and that decision gets made properly, in writing, before anything else happens.

When an MVP sprint is the right call

  • You have a clear idea of the one job the product does.
  • You need something real in front of users soon, not a perfect thing eventually.
  • You would rather learn from real usage than from more planning.
  • Your budget is closer to £3,000 than £30,000.

When it is not

  • You need continuous development for years. Hiring in-house will cost less over that horizon.
  • Your product is a game, or depends on heavy real-time infrastructure. We do not build those, because they genuinely need months.
  • You are in a regulated space that requires formal clinical or financial certification before launch.
  • You do not yet know what problem you are solving. That is not a build problem, and a sprint will not fix it.

Common questions

How long does MVP development take?

Fourteen days with us, from kick-off to store submission. The UK market average for an agency-built MVP is three to four months. The difference is scope discipline, not shortcuts.

What counts as an MVP?

The smallest version of your product that does the one job it exists to do, well enough that real users will use it and tell you what to build next. Not a demo, and not a prototype.

Do I own the MVP code?

Yes. Full source code, your accounts, your store listings, from day one. No licence fees and no lock-in.
