I did that in 2008 by going to Salesforce. It worked out really well. Highly recommend.

So you stayed for the entire 4 year vest then?

Three and a half years, vested most of it, and then a bigger opportunity came knocking.

maybe not yet, unless a super early company, since no one is worth the round they raised in the last 6mo, which is what determines the strike price you'll get today. You're either looking for a down round, or a company that hasn't gone up yet.

Or a public company that took it in the chin over the last 4 months. With public companies you get the market price at the first board meeting after hiring, and you don't take quite as much risk of your stock being totally worthless as you would with a down round or unknown company.

is it still called a "strike price" when dealing with RSUs?

I agree with you but I took parent to imply startups & options

Generally not but I think parent probably was referring to RSUs but could’ve worded it better

Are the strike prices calculated on the start date then?

The average price over the previous month (with Meta at least)
