In the startup world \u2014and really, in any company with more than one founder\u2014 there\u2019s a legal tool that often goes unnoticed\u2026 until it\u2019s too late: the shareholders\u2019 agreement<\/a>.

This is signed at the beginning of the project, when everything is just getting started.<\/strong> It\u2019s where the co-founders agree \u2014in writing\u2014 on things that are often just assumed verbally: what role each one plays, their level of commitment, who owns the IP, what happens if someone leaves early, and more.<\/p>\n
