Your AI prototype looks good. What's behind it?
Built with Lovable, v0 or Bolt? It usually breaks here:
No solid base
No real backend, database or security.
Not ready for the stores
Apple and Google reject it.
Hard to update
Every update is a risk.
Can't grow
Fine with 5 users. Breaks at 500.
We take what you have and make it ready for real users.
What we do
New app
One app for iOS, Android and web, from the first idea to the app stores.
Prototype rescue
We add the backend, security and tests, and make sure Apple and Google approve it.
AI features
Voice, chat, document search, automatic reports. We check how accurate they are and what they cost.
Made in Germany. Ready for EU rules.
We plan for privacy and EU law from day one, not at the last minute.
GDPR from day one
Every app asks for consent, can delete user data and has a privacy plan.
EU hosting
Your users' data can stay on servers inside the EU.
Accessible
Built to EU accessibility rules, so more people can use your app.
Team in Germany
We speak English, German and Turkish and work on Berlin time.
