After early GitHub and GitLab, I started getting into angel investing. I've done a couple hundred investments into startups over the years, and I kept waiting for someone to build something to like, track these damn things better, since they're not publicly traded and it's such a pain to even begin to track all this stuff.
But no one did! So I'm doing it.
Initially it's targeted to angel investors, but it's also great if you have stock with your employer. One of the things I wished I had done differently back at GitHub is to treat my stock like an investment rather than just "something that happened to me". First step in doing that is to just track it and measure it.
It's free to sign up and use, and then there's paid plans if you're more serious about your finances. Curious to hear your thoughts!
