You’ll know by your first crisis, or at least the second, if your co-founder is really as committed as you. It may be murky until then.
A time will come however, when your startup almost dies. You lose your only customer. The site goes down for hours. A database is corrupted. A financing falls through. A key employee you can’t survive without — quits.
They you’ll know.
Does your co-founder talk about throwing in the towel?
Or does she talk about how to fix the seemingly unfixable issues?
You’ll know …
This is why the most committed cofounders are protected by the longest cliff, and the longest vesting period.
