LaunchFlow Sprint
Validate your idea with a working prototype
From £3,500 · 2–4 weeks
What you get
LaunchFlow Sprint is for founders who have an idea but need to prove it works before investing in a full build. In 2–4 weeks, you get a working web prototype you can put in front of real users.
Working web prototype
A real app your users can interact with — not a static mockup or slide deck.
Shareable URL
Send it to test users, investors, or your team. No app store, no downloads — just a link.
Core feature set
We focus on the features that matter most for validating your idea — nothing extra, nothing wasted.
Signups and payments
Add real user signups and payment flows to gather proof of demand.
Built for expansion
Uses the same React Native and Expo codebase as LaunchFlow Complete — nothing gets thrown away.
How it works
Kickoff call
We define the core problem, target users, and the minimum feature set needed to validate your idea.
Build sprint
I build the prototype with daily or weekly check-ins so you can steer the direction as it takes shape.
User testing
Share the prototype with real users and gather feedback. We refine based on what you learn.
Decision point
You now have evidence. Continue to LaunchFlow Complete, pivot the concept, or walk away — with clarity either way.

- → Founders who want to test an idea before committing to a full build
- → Startups preparing for funding who need a working demo
