ProofStack

An evidence audit of your product

Everything this site does automatically -- pricing benchmarks, search demand, competitor playbook teardowns -- re-run against your product and verified line by line by a human. $99, delivered in 48 hours, at most three per week. Every figure carries its source.

Delivery first, payment after: you pay once the report is in your inbox and you have checked its sources. If it is not worth it to you, you owe nothing.

See exactly what you get: a complete public sample audit (RSS + AI readers) — every number carries its source and observation date.
