Show HN: I built a fun way to learn why startups succeed/fail 1 guess at a time

https://www.startuporflop.com/?y
2•Belsonsan•1d ago
I’ve been studying real-world SaaS ideas some that worked, some that didn’t. To make the learning more fun (and a bit addictive), I turned it into a side project: Startup or Flop.

Each round gives you two real startup ideas. One worked, the other didn’t. Your job is to guess which is which. After each guess, you get the actual outcome and a short explanation of why it worked or didn’t.

It’s a quick, easy way to:

Hone your product sense

See patterns in startup success and failure

Challenge your own assumptions and biases

Surprising, humbling and kinda fun. Let me know if you have wild startup stories (win or fail) I’d love to include them!

Hey folks — I'm Henri, a solo dev and product enthusiast based in Europe. I built this mostly for myself at first, as a way to train my product intuition and avoid falling in love with my own startup ideas too quickly. I’ve made some bad bets in the past (who hasn’t?), and I realized how easy it is to assume we know what works just because something sounds smart. I wanted a fun way to challenge that — to learn from real examples without reading 50 postmortems.

Would love to hear what you think, especially if you’ve built something or are in the early stages of a project.
