Launch Integrations That
Deliver.
We ship products with all launch-critical integrations pre-built — authentication, payments, email, analytics, and monitoring — so your launch isn't delayed by integration work that should have been done in week one.
Start GrowingWhat holds teams back
Billing integration always the last thing done
Stripe gets added in the final week. It's rushed, untested, and the source of most launch-day bugs.
Auth built from scratch every time
Teams spend a week on authentication that could be integrated in a day with the right patterns.
How Greta delivers it
Launch integration bundles — pre-built patterns for auth (Clerk/Auth.js), payments (Stripe), email (Resend), analytics (GA4), and monitoring (Sentry) — all connected and tested as part of the MVP build.
How we build it
Integration selection
Choose the right tool for each integration based on your stack and scale.
Pre-built pattern setup
Implement using proven patterns that eliminate common integration bugs.
End-to-end testing
Test every integration flow — signup, payment, email — before launch.
Monitoring and alerts
Add health checks for every integration so failures surface instantly.
