Day 10 building AffiSpark.

This week the most useful feedback did not sound encouraging. It sounded skeptical.

"Paying before seeing the setup is weird" led to a public preview.

"Request walkthrough doesn't work" led to a real in-browser request flow.

Both comments were more useful than praise because they named the exact place trust broke.

I think founders often want encouragement when what we really need is resistance.

Praise tells you what already sounds good. Pushback shows you where the story and product stop matching.

My current rule: when someone pushes back, ask what assumption of yours they just exposed.

What skeptical comment improved your product more than supportive feedback did?
