62% of startup failures involve co-founder conflicts, with equity disputes being a leading cause. The default 50/50 split rarely reflects actual contributions and often leads to resentment. Fair equity splits account for cash contribution, time commitment, idea origin, risk taken, and role value. Having a clear, justified split from day one prevents the most common source of founder breakups.
