This document provides advice on choosing co-founders and building a startup team. It recommends finding a co-founder to share the stress of starting a business and distribute responsibilities. Investors see the startup as a team, so choosing a co-founder is the most important decision. The document advises picking no more than 3 co-founders, as 2-3 is ideal and 5 can be a disaster. It is better to have no co-founder than a bad one, and if not technical, a technical co-founder is a must. The document also recommends starting small and only hiring when desperately needed to avoid bad hires that can kill a startup.
