South Park Commons is a venture capital fund that originated as an intellectual community for experienced technologists to explore their next move without pressure to immediately start a company, filling what the NYT called "a hole in the tech landscape" between jobs, grad school, and traditional accelerators. Founded by Facebook's first female engineer and Dropbox's former CTO, SPC codified the "-1 to 0" philosophy as a formal pre-idea exploration phase and invests $400k for 7% plus $600k guaranteed in the next round to people before they have concrete startup concepts, which is more extreme than typical pre-seed funds.
