Choosing a cofounder can be a make-or-break decision for startups. On one hand, cofounders can bring needed skillsets and other resources that an individual founder may lack.

For example, recent evidence suggests that up to 43% of founders are ultimately forced to buy out their cofounder due to interpersonal rifts and power struggles.
