Your AI-built app works. Now make it safe to launch.
Lovable, Bolt, Cursor and Replit get a working product in front of users fast. The gaps show up when real users, real data and real money arrive.
What we usually find
- Database rules that let any logged-in user read other users' data.
- API keys shipped to the browser.
- Payments that work in test mode but don't handle failed cards, refunds or webhooks.
- No backups, no error monitoring, no staging environment.
- One very long file per screen, so every new feature breaks an old one.
What the hardening sprint covers
- Security review and fixes: auth, row-level access, secrets, input validation.
- Data: schema clean-up, migrations, backups you can actually restore.
- Payments: Stripe webhooks, failed payments, refunds, invoices.
- Deploys: staging and production, CI, error monitoring and alerts.
- A short written report of what was fixed and what to watch next.
| Engagement | Price | Timing |
|---|---|---|
| Hardening sprint | from €5,000 | 2–4 weeks, fixed price after a free first look at the code |
| Rebuild on a clean codebase | from €19,500 | When the prototype has proven demand and the code can't carry the next stage |
Industry write-ups in 2026 describe most AI-built apps as needing a 2–4 week hardening sprint in the $5,000–15,000 range, not a full rebuild.
