>What this would mean is every month, when your equity compensation vests a little bit, you will owe taxes on it even though you can’t do anything with that equity compensation.

I'm not sure what he means with regards to RSUs.

When my RSUs vest, I am taxed on them currently. And I can do whatever I want with them. My employer gives me RSUs with a 4 year vesting period - a quarter vests every year. And every year a quarter of those stocks are given to me to do whatever I want with them.

Perhaps he was referring to something other than RSUs? Or it is only relevant for private companies (which all startups are)?
