What if I have zero customers?
That’s a valid input and a common one. Zero customers is itself a signal: the diagnosis focuses on the earlier stages to show where people are dropping out before they ever reach payment.
Is it a subscription?
No. The funnel diagnosis is free. The Full Founder Triage is a single $39 payment. There is nothing recurring to cancel.
Does it guarantee my startup will work?
No. Nothing can. Founder Triage tells you where to look first and why, so you stop spending months on the wrong fix. What you do with that — and whether the market wants your product — is still up to you and your customers.
