Why most launches stall
Most founders lose their first month rebuilding auth, billing, and email. A saas starter kit hands you all of that on day one, so the only thing left is the part that actually makes you money.
The weekend path
Fork the kit, rebrand it, wire Stripe, point your domain. That is the whole loop, and none of the steps take longer than an afternoon.
Ship it
Run one real checkout, then announce. The moment money moves, you are a real business and everything after that is iteration.
