VERDICT

Should I use The Mom Test?

How to talk to customers & learn if your business is a good idea when everyone is lying to you. - momtestbook.com

Worth it. Buy it if you're building any product and will talk to customers — it's cheap, short, and consistently recommended across founder communities. Skip it if you want software that runs or automates discovery, or you've already mastered lean customer interviews.

Confidence

High. Based on ~30 public sources: reviews, summaries, and community threads; no security findings.
