The early leaver keeps the cap table
A co-founder leaves early with a large stake. The remaining team does the work while the absent founder keeps the economics.
Glossary
Reverse Vesting
Reverse vesting lets a company reclaim unvested founder shares if a founder leaves before earning them through time or contribution.
Plain definition
What it means.
Reverse vesting is commonly used for founders who receive shares upfront at incorporation. The shares are issued, but the company keeps a repurchase right over the unvested portion if the founder leaves early.
The structure is meant to protect the company and remaining founders from a cap table where someone owns a large stake after stopping contribution. It matters most before the first real disagreement, because after that the conversation is already more expensive.
Reverse vesting turns founder equity from a permanent gift into equity that has to be earned by staying in the work.
What goes wrong
Where this term becomes expensive.
The investor prices the mistake
Future investors see dead equity and ask who controls it, whether it can be cleaned up, and how much pain the cleanup will cause.
The remaining founder loses hiring flexibility
Equity that should help recruit senior talent is locked with someone no longer building the company.
The buyout becomes emotional
Because the agreement did not define what happens on early departure, the cleanup becomes a personal negotiation at the worst possible moment.
Business owner questions
Common owner questions.
What is reverse vesting?
Reverse vesting is a structure where founder shares are issued upfront but remain subject to company repurchase until they vest over time or contribution.
Why do founders use reverse vesting?
It protects the company if a founder leaves early. The equity follows continued contribution instead of staying permanently with someone who stopped working.
How is reverse vesting different from normal vesting?
Normal vesting often grants equity over time. Reverse vesting issues shares upfront, then gives the company a right to repurchase unvested shares if the founder leaves.
When should reverse vesting be set up?
At incorporation or before meaningful value accumulates. Once conflict appears, the same structure becomes much harder to negotiate.
