  • I scanned 2,500 startup ideas with AI. Here is what the data says about why most fail.
    I built Test Your Idea, an AI tool that scans startup ideas against 40+ live data sources and scores their viability. After 2,500+ scans, I started noticing patterns that challenge a lot of the startup advice you see on Twitter. - Source: dev.to / 7 months ago
