Hi HN! I made a really quick web app to help people validate their ideas. The app is a simple landing page builder, but every page includes a really simple Yes/No "Are You Interested?" poll.

This makes validating ideas super easy because you can post your link to different communities and get statistically significant results as well as build an email list. Given an hour, you could easily create 50 different landing pages and be able to validate your ideas in bulk. The…

Hi HN! I've been working on a small project called DemandHunt. Basically I aggregated problems in niche communities so that you as an entrepreneur can take inspiration. The background is that I've worked with a number of startups and I've found that many entrepreneurs already have a technology or solution in mind and work backwards to find the people with the problems to solve. This is YC's "Solution in Search of a Problem" problem, and my understanding is that it's typically better to work the other way around so you can build the right solution for the problem you find instead. Thus I…
