They make their own products/teams/companies then spin them out as appropriate, rather than having pre made teams and products apply to a program.

A year ago I looked at my life and realized I really enjoy and get fulfillment out of three things:
1) learning about new industries and thinking about how technology can improve them
2) developing products and consequently seeing numbers go up (users, revenue, anything really)
3) mentoring people I really enjoy the company of over extended periods of time (years)
Zero-F is my attempt to build a thing where I maximize my ability to do those things. It isn't a program or application based. It's me opportunistically building 1 to 2 startups a year with friends or people in my extended network or even new people. I provide business building insight, product knowledge, capital, recruit talent, and they bring grit.
