I built Idea Katalog after I ran out of startup ideas I’d been collecting in my notes app.I wanted to work on something new but had no idea what to build, so I used Opus and Fable to generate thousands of B2B software ideas, filter them down, and research the 200 that seemed most promising. I put the results into a browsable list with the problem, target customer, competitors, market, and other research for each idea.Please let me know what you think, and I hope you find your next business idea from this list :)
