My first angel check came from my childhood friend who I made money for when I published a co-authored book in Lautech.
But my first outside check came from someone watching me on LinkedIn, he liquidated his 401k and handed me all of that money,that's a burden I'll carry till...
I got my first angel check 8 years ago from someone I met on this app. We still haven't met in person.
Key is to do good work, post about your work and put yourself out there. Capital always finds those that are earnestly making progress and are willing to do the real work.
