May I ask how you got the opportunity to invest in this company? If you are a VC, makes sense, just wondering how normies can get access to invest in companies they believe in. Thanks
YC lists all their companies here: https://www.ycombinator.com/companies.
Many companies are likely happy to take your small check if you are a nice person and can be even minimally helpful to them. Note that for YC companies you'll probably have to swallow the pill of a $20M valuation or so.
