Without an agreement, a co-founder’s departure can lead to messy disputes over equity, valuation, and intellectual property. A Co-Founders’ Agreement proactively outlines clear exit clauses, such as: the terms on which co-founder can be terminated or resign, how vested and unvested shares are handled, buy-back options for vested shares, valuation methods, and the handling of IP, ensuring a smoother transition and protecting the remaining founders’ interests.
