Not less, as most entrepreneurs seem to believe (and god forbid you think “the VCs have the option to put in more money” is economically advantageous to you).

Here’s why. Black and Scholes (and Merton) won a Nobel prize for inventing the Black-Scholes model, which was the first model that somewhat accurately modeled options pricing. Using this model, and making a few reasonable assumptions (the option is “near the money,” the maturity is sufficiently far away), the key driver of an option’s value is volatility (in fact, if you listen to option traders talk, they actually talk about prices in “vols”). In public markets, options are usually priced at some fraction of the share price. This is because public stocks under normal circumstances have volatilities around, say, 20% (at least they used to 10 years ago when I was programming options pricing algorithms). …”
