Cofounders Need to Learn How to (Productively) Disagree

Evelyn Nam · Harvard Business Review Freemium Beginner

Sometimes the two ideas are a proxy for a deeper problem: you have no agreed way to make a call when you disagree. This HBR piece treats disagreement as a skill and pushes you to set decision rules in advance, including who gets the final say on which kinds of calls, so a single stuck choice does not calcify into resentment. It is short and pairs well with a disagree and commit rule: back one idea for a defined window with pre-agreed metrics, then review.

  • Decide ahead of time who owns which decisions, so a deadlock has a built-in tiebreaker instead of grinding to a halt.
  • Commit to one direction for a set period with clear metrics, then revisit, rather than relitigating it every week.
  • Unresolved founder conflict is a leading reason startups fail, so treating this as urgent is warranted, not dramatic.
