What you can build
A multi-tenant web app with logins, a dashboard, billing, and a custom domain. Real production code. Real paying customers.
Why this matters now
What used to require a technical cofounder, $50K, and three months now requires a clear idea and an afternoon. The bottleneck isn't building anymore — it's deciding what's worth building.
