Why Open Startup?

Most startups hide their numbers until they have something impressive to share. We believe transparency builds trust — especially when you are asking developers to trust your tool with their database schemas.

📡 Real-time updates
This page is updated whenever we ship something meaningful. No quarterly reports. No spin.
🤝 Accountability
Publishing our metrics keeps us honest. If we say we are building something, you can verify it here.
🎓 Learning in public
Other builders can learn from our wins, losses, and pivots. The $100 AI Startup Race is a shared experiment.
