sorry for the late response. For now I'm not using AI, just some basic data from crunchbase to filter out companies (for example the industry the company is in, I only keep greentech, edtech and medtech companies), but I'm thinking about making a classifier that can detect if a company is doing some "meaningful" work, by looking at it's description, what's it's selling, at how people talk about it on the internet. I scrape them from lots of places(indeed, linkedin, a lot of smaller sites). UMSO is pretty easy and fast to use, but they could do better in terms of functionality
