An angel investor joined our startup. After giving the money, they added a clause to the contract: 'Founders' shares will vest over 4 years. 25% vests each year, condition: founders must stay in the company, otherwise shares are clawed back.'
As I understand it, this is for risk management. If I or the other founders leave, the shares we shared are lost. But honestly, this feels very scary. Is this normal, does it happen to others, should I accept it?
If we need the money we'll have to accept it, but I'm curious: is vesting common, and what exceptions should be in the vesting clause?
