Business Idea Depot: Validate your idea before building

Hey Product Hunt 👋 I'm Kevin, maker of Business Idea Depot. This started with a frustration a lot of you will recognize: I'd get excited about an idea, "research" it by doom-scrolling Reddit and Googling "best SaaS ideas 2026," then build for two months — only to discover nobody wanted it. So I built the tool I wish I'd had. Type any idea (or paste a URL) and BID scores it on real demand signals pulled live from Hacker News, Reddit, Wikipedia, GitHub, Stack Overflow and Dev.to. You get a 0–100 signal score, a 12-month momentum trend, opportunity/feasibility/timing reads, a transparent revenue model, the existing players, and a build path. There's also a live feed of problems people are posting on Reddit right now, App Store review-gap analysis, and AI matching to ideas that fit your skills. The part I care about most: no black box. Every number traces back to a real public API call — we show the source, the units, and exactly what the score does and doesn't mean (it measures demand interest, not guaranteed revenue). No paid data, no recycled list someone picked for you. It's a one-time payment for lifetime access — $29 for the first few of you, then it steps up. I'll be here all day: drop an idea in the comments and I'll run it live. And I'd genuinely love your brutal feedback on what's missing. 🙏
