The three of us here have extensive experience in dealing with co-founder relationships, including many founder breakups, which often lead to the company's failure due to interpersonal issues rather than business problems.

Founder relationships are crucial to a startup's success; founder breakups can severely impact productivity and morale.

In co-founder conflicts, it's essential to communicate openly, as most relationship issues stem from communication breakdowns.

Founder breakups can become contentious if founders haven't paid themselves, leading to leverage for the fired founder in negotiations.

Cofounder relationships are critical to a startup's success, and cofounder disputes can significantly harm productivity and morale.

Self-abandonment in co-founder relationships can lead to burnout and unresolved issues, which ultimately harm the startup.

It's important for co-founders to know how they will respond to each other during conflicts, as the co-founder relationship is as significant as a long-term romantic relationship.

Having different work ethic expectations can strain co-founder relationships, especially in the demanding environment of a startup.

In cases of unequal equity splits, a common mistake is assuming that one co-founder deserves a significantly larger share simply because of an agreement, which can lead to imbalances and conflicts.
