We built Dayzero because “looks great!” isn't useful feedback
Hey Indie Hackers 👋
We’re building Dayzero — a product-testing exchange for builders.
We kept running into the same problem:
You build something for weeks, show it to someone, and hear:
“Looks great!”
But what did they actually understand? Where did they get stuck? Would they use it? Would they pay?
Getting genuinely useful feedback before launch is surprisingly hard.
So we built Dayzero.
The idea is simple:
You test someone else's product for 10 minutes → they test yours.
No paid testing panels. No subscriptions. Just builders giving builders useful feedback.
Testers follow a structured set of questions around:
First impression
Clarity
Bugs & rough edges
Usefulness
Willingness to pay
Biggest improvement
The goal is to help you answer one question before you spend another month building:
“Does this actually make sense to someone who isn't me?”
We're still very early and looking for builders to try it out.
If you're building something, how are you currently getting feedback before launch?
