I built a game where you guess which startup idea succeeded
I’ve been studying real-world SaaS ideas — some that took off, others that failed hard. I turned it into a small side project: StartUp or Flop? You get two real startup ideas. One became successful, the other didn’t. You guess which is which, then you get the actual answer plus a short explanation of what made it work (or not). It’s a lightweight way to learn from real startup outcomes, uncover the patterns behind success and failure, sharpen your product instinct — and maybe even confront some of your own startup biases along the way. It’s surprising, humbling, and kind of addictive. Would…

- IMI made a tool to help collect and validate startup ideas2024 · keepmyidea.app · ▲38
Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!
- IAI accidentally built a startup idea validation tool2025 · validationly.com · ▲15
I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool. A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.” It’s very rough, but it works, and it’s already making me rethink a few of my own ideas. It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/
My startup-idea scanner scored 500 ideas; the best got 6.3/107d ago · 1mil.app · ▲8I built a tool (https://1mil.app/hn) to help me test my intuition about various weird business ideas that were on my mind. Initially, I wanted to create a database with 1 million business ideas (hence the name - "1 million opportunities"). But turned out to be a dumb idea already. So instead I built this tool that returns only 10 ideas. It's all based on your input, market + your background. The first release scored on demand only and it gave false confidence. So I rebuilt the the scoring around "winnability": can a solo founder with a specific background "win" against what…
