There is no fixed rule, but the amount most boards are comfortable with is small: often something like 5 to 15 percent of a founder's holding, or just enough to cover a specific goal (a home, clearing a loan, a safety cushion) rather than a change of lifestyle. The test investors quietly apply is whether you still have far more to gain from the company winning than from the cash in hand. A modest sale that leaves you highly aligned reads as sensible de-risking. A large one reads as a founder heading for the door. Frame the ask around a number and a reason, not a percentage in the abstract.
