You're building the wrong thing and nobody around you will tell you!

Unpopular opinion:

Тhe #1 reason startups build features nobody uses isn't lack of user research. It's lack of disagreement.

I've founded four companies. And the pattern that killed features -sometimes entire products was always the same. Not "we didn't talk to users." We did. The problem was that I filtered everything users said through what I already wanted to build. And there was nobody around me with a different lens to say "you're hearing what you want to hear."

Here's what I mean. A user says "I wish the dashboard was easier to use." A founder hears "redesign the dashboard." A CFO would hear "how much will a redesign cost vs. how many users are actually churning because of this?" A growth person would hear "is the dashboard even the retention lever, or is onboarding the real problem?" An ops person would ask "can we solve this with better documentation instead of a 3-week sprint?"

Same user feedback. Four completely different conclusions. But when you're building with a small team, you usually only hear one -yours.

I think the entire "talk to your users" mantra is incomplete advice and possibly dangerous. Talking to users without people who interpret that data from multiple angles just gives you a more sophisticated version of confirmation bias.

But I want to challenge this community on something:

Do you actually believe founders can interpret user feedback objectively? Or is the "I talk to my users" confidence just another form of building in an echo chamber?

For those who've shipped something that completely flopped despite "validating" it with users -what actually went wrong?

And the spicy one: is the whole lean startup "build-measure-learn" loop fundamentally broken when there's nobody to disagree with your interpretation of the data?
