Frequently asked questions

Should co-founders have vesting?

Yes. Four-year vesting with a one-year cliff is standard and protects the company if a founder leaves early.

What is an 83(b) election?

A filing with the IRS within 30 days of receiving restricted stock, electing to be taxed on its value at grant rather than as it vests. Get tax advice.

What happens to a co-founder's equity if they leave?

Unvested equity is usually repurchased; vested equity is kept unless the agreement says otherwise.
