Angel checks
small checks into founders I believe in.
I write small angel checks alongside my own companies. No fund and no thesis deck: just conviction in specific founders, most of whom I've watched operate up close. Company names link to their sites; the mono links on the right point to each latest public milestone. Some of these will be huge, some already wound down. That's the game.
