5 years ago, after failing with a startup idea and being rejected from YC, I started interviewing founders with the hopes of learning what it takes to find a good idea and build a successful business.<p>I posted these case studies online (started as a side project) and eventually it turned into a business, and started making enough money for me to go full time on it (starterstory.com).<p>For the last 5 years I’ve been collecting data for each company we interview, such as revenue, startup costs, age of the company, gross margin, what channels they used to grow, and a ton more.<p>I’ve put all of this into a searchable, sortable, filterable database and I wanted to get HN’s opinion on the tool, and if you find the data / information useful? Also, would love to hear what other data points you think we should be collecting, or features we should add!<p>The tool is built with Rails, Postgres database, search functionality using Elasticsearch, and it’s hosted on Heroku.
