Interesting to see that of the top 10, 4 are non-US companies while 5 are based in the Bay Area. Only SpaceX breaks the NorCal trend with it’s Hawthorne, CA headquarters.
And it’s not until you get to Fanatics at #22 that you find a non-CA / non-foreign-based company. You have to go even further to MongoDB at 25 to find a company located in New York.
