Here's one data point from a $270M exit:

Joined post-series-A at 0.2%. These initial options eventually got diluted down to 0.05%. I did get "re-upped" with more options over the years, so when the company exited seven years later, my total was about 0.085%.

I ended up with an extra $227K for my efforts. This was on top of an above-market salary. Not too bad, but did fall short of my expectations.
