"Stop the leak" is about the moment right after signup where new users quietly disappear before they ever get value — the highest-leverage fix in an early SaaS, because keeping a signup you already earned is cheaper than winning a new one.
Free Builder's scaffold already wires the hard parts — auth, payments, frontend, backend — so the leak is almost never "we don't have login." It's friction: too many steps before the user sees anything useful. You fix it the same way you build everything else: you direct an AI worker, you don't hand-code it.
A fast pass looks like this:
- Pull your signup-to-first-action funnel and find the step where people drop off.
- Tell your AI worker the exact step and ask for a shorter path inside your existing scaffold.
- Have it implement the fix — usually a redirect, a sensible default, or a field you can cut.
- Review the change yourself, the way an editor reads a manuscript without writing it.
- Ship it and watch the next batch of signups.
That's the operator posture the whole framework runs on: your judgment decides what's worth fixing, the AI worker does the work. Onboarding fixes like this are exactly the kind of thing operators trade in the community — bring your version, take someone else's.
