Founders validating an idea
MVP Lite builds one core flow without payments in 7 days, so you can put a real product in front of users and learn whether the idea holds. What users do with it tells you what to build next.
AI & Automation
A working product on your domain in weeks, not quarters
You have an idea and a deadline, and agencies quote quarters and €40k. We ship a real production app on your domain: Next.js 14, Supabase, Stripe, authentication and CI, all in your accounts from day one. Not a prototype and not a Figma file — a product people can sign up to and, from the Pro tier, pay for.
Who it is for
Teams ready to sell
Pro adds user accounts, payments and 3–5 features — enough to charge the first customers and see whether they pay.
Products with several user roles
Scale covers multiple user roles, integrations and advanced features for products that need more than one type of user from the start.
How it works
- 01
Scope in a short SOW
We lock the scope in a short statement of work where every line is a verifiable outcome. New ideas during the sprint go to the backlog for the next one, which is what keeps the date.
- 02
Build in your accounts
Code goes to your GitHub, hosting to your Vercel, data to Supabase and payments to Stripe. You can follow progress from the first day. Nothing has to be transferred at the end.
- 03
Launch on your domain
The app goes live on your domain with authentication, CI/CD and, from Pro, working payments.
- 04
Handover
Signed source and infrastructure handover at the end of the sprint. A retainer is optional — we don’t trap you.

Questions
How much does an MVP cost?
MVP Lite is €6,990, Pro €12,990 and Scale €24,990, fixed and excluding VAT. A 50% deposit locks the build window; the balance is due on go-live. Classical agency quotes for a comparable MVP usually start around €40k.
How long does it take?
7 days for Lite, 14 days for Pro and 21–28 days for Scale. If the production deploy does not happen on the date in the SOW, half of the fee is refunded automatically.
Who owns the code?
You do, from the moment the SOW is signed: source code, documentation, configuration and the intellectual property in them. The repository and infrastructure sit in your accounts, and we have no right to reuse or resell your code.
Is the product GDPR-ready and hosted in the EU?
We host on EU infrastructure, set up row-level security in the database and include a data processing agreement. If your product will handle sensitive personal data, tell us at the start so the required controls are part of the scope.
What do you need from us?
A clear description of the core flow, your brand assets if you have them, GitHub, Vercel, Supabase and Stripe accounts in your name (or permission to create them) and one decision-maker available during the sprint. Fast answers from that person keep the date safe.
