Prove
Evidence Sprint
We design and build one core flow as a working app on a live URL, test it with 5 to 8 people from your user group, and give you a fixed price for the full build.
- Price
- From €9,500
- Length
- 3 to 4 weeks
- Step
- Prove
Before you spend months and a lot of money on a build, a working version can settle the question faster than going through round after round of reviews. We build the flow you're least sure about, about 5 to 8 screens, on a live URL with seeded or real data, and with live AI calls where the flow needs them. Then we put it in front of real users and write down what happened. At the end, you decide if it's worth building, and you know what the build will cost.
Who it’s for
- Teams that need to see a flow working before they commit engineering time
- Founders who want evidence before they raise or build
Scope
What’s included, and what isn’t.
You get
- A working prototype of one core flow, about 5 to 8 screens, on a live URL
- Testing sessions with 5 to 8 people from your user group
- A written test report with what worked and what didn't
- A fixed price for the full build, or a recommendation to stop
Not included
- A full product or an MVP ready for paying customers
- A multi-feature app, a social network, or a marketplace
- A production backend, security hardening, auth, or payments
- A second flow, or ongoing maintenance
If the sprint shows the idea works, we scope the full build separately, and the price you get at the end of the sprint is the price you pay.
How it runs
What happens after you book.
- Week 1
We interview your team and a few users, and agree on the one flow to build.
- Week 2
We design and build the flow as a working app on a live URL, in your design system or a clean token set.
- Week 3
We run the testing sessions and record what people do and say.
- Week 4
You get the test report, the decision, and a fixed price for the build.
What we need from you
- One decision-maker on your side
- Help reaching 5 to 8 people from your user group
