Our mission is to help more people start better startups. ODF is a program we created over four years ago to help those at the exploration stage of starting a company. So far, weve helped over 1000 companies get started and raise over $2 billion. Starting a company is really exciting, but there are so many things you need to figure out in order to actually build one. - "Who might I start my company with?" - “What might we build?” - “Who might our initial customers be?” - “Should we raise funding soon, or should we try to bootstrap in the beginning?" These and many more questions are what we refer to as the "missing pieces"—the things you need to figure out to know if starting a company is right for you and what company you should ultimately build. With ODF, we bring together 80 to 100 people who are at the very same stage as you. Theyre all exceptionally talented, and theyre all trying to figure it out together.
