Sonu Goswami (SaaS content writer B2B) SaaS Founders: Fix How You Validate Product Ideas
The Book That Saved My SaaS Friends Months of Work
Author (Book Review)
Not a founder here — I come from the marketing side. But after working with enough early-stage SaaS teams, I’ve seen the same trap: they think they’re validating, but really, they’re just getting polite lies.
You know the kind:
Oh, that’s cool!Yeah, I’d use that.
Sounds promising — keep me posted!
Then… silence. No signups. No usage. Just a bunch of good vibes and a false sense of progress.
That’s why The Mom Test by Rob Fitzpatrick hit home for me.
It’s a tiny book with a brutally honest message:
If you ask bad questions, people will lie to you — not because they’re bad people, but because you made it easy for them to lie without even realizing it.
What This Book Taught Me (and Should Teach Every SaaS Founder)
- Don’t ask: Would you use this?✅ Ask: When’s the last time you had this problem?
- Don’t explain your app first.✅ Ask what they’re already doing today.
- Sounds cool* means nothing.*✅ A messy workaround they’ve created? That’s real interest.
Why This Book Matters So Much for SaaS
I’ve watched people spend months building what someone *said* they wanted — only to launch it and get nothing but tumbleweeds.
This book doesn’t promise to fix your idea. But it will fix the way you talk to users — and that alone can save you months of wasted work.
It helps you stop fishing for compliments and start digging for truth.
Visual Recap
Here’s a quick visual summary of the core lessons from *The Mom Test*:
Find people to talk to, request a meeting, prep your top 3 questions.
- Before: Find a people talk to you, Request a meeting, Prep the 3 top questions.
- During: Ask good questions, take good notes, ask for a commitment.
- After: Do a team review, update your data/goals, make it count.
- Don’t seek validation, don’t ask for opinions, don’t lead the witness.
- Smart discovery: Focus on past behaviors, dig into specifics, listen more than you talk.
- Gather real insights: Look for pain points, workarounds, and motivations.
Polite feedback leads to wasted effort.
- The Solution: Ask about past behaviors and real problems, not hypothetical futures.
Read It Before You Waste Time
It’s short. No fluff. Just solid, real advice.
If you’re building something — or helping someone who is — *The Mom Test* might be the most useful hour you’ll spend this month.
