"You Haven't Earned It Yet": The Vesting Cliff Nobody Will Talk About

The one-year cliff is two months away. Your cofounder has been coasting for three. You both know it, and neither of you has said it, because saying it means deciding whether they stay or go, and that decision rewrites the entire company. Vesting was supposed to protect you. It was the safety valve, the insurance policy against exactly this scenario: someone stops performing, they don't get the shares. Clean, fair, mechanical.
Except it stops being mechanical when the person is your partner, when you built the pitch deck together, when they introduced you to your first investor. So you let the cliff approach and hope the problem solves itself. Maybe they'll pick it up. Maybe they'll leave on their own. Maybe the performance issue was temporary and you'll laugh about this over drinks in three years. You won't. The cliff is a deadline for a conversation, not a replacement for one, and every day you wait, the conversation gets more expensive.
The avoidance is the whole problem
Two things are happening at once. Your cofounder's coasting points to a drop in the Conscientiousness facets, Dutifulness and Self-Discipline, that keep someone producing when the novelty of a startup wears off. Your silence points to your own low Assertiveness on the hardest possible topic, because confronting a friend about their equity is exactly the conversation a conflict-averse person will do almost anything to postpone. The vesting schedule was built to make this decision impersonal, and you are letting the relationship override the mechanism it was designed to enforce.
The move is to treat the cliff as what it is, a forcing function for a talk you are already overdue to have. Sit down before the date, name the performance gap plainly, and give your cofounder a real chance to re-engage with a clear standard attached. Some people, told directly that their shares are on the line, come back. Others confirm they were done months ago, which is painful but is the exact information vesting exists to surface. Letting the cliff pass in silence just converts a hard conversation into a permanent, unspoken grievance.
The Conscientiousness drop behind the coasting and the Assertiveness gap behind your silence are both measured by the 30-facet OCEAN personality test in about 15 minutes, with domain results free. If a cliff is approaching and no one will name it, seeing both profiles clarifies whether you're looking at a temporary dip or a durable trait, the same way our role-profiling for teams distinguishes a slump from a pattern.
