    I started a newsletter sending out daily startup ideas. After a year, I transitioned to weekly ideas with more in-depth details. I recently posted all of them to the website and made them searchable. Check it out and let me know what you think. By providing more than just an idea, my hope is to help someone start their next business. https://www.startupsfromthebottom.com/

Every vote is recorded and tracked, and if they click yes they are brought to a page where they can submit an email. 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.

    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/
