This number makes complete sense. I was a 'key employee' once upon a time - in a startup that had just raised f&f, and I received a FULL 2% (unheard of for Canada).
Fast forward through the (usual) reality of 6 rounds of dilution, and my 2% was worth less than 0.02%. If the startup went from a $2M valuation to $200M (as it did) then my take would have been $40K.
Do with that what you will.
