I recently left a long career in FANG to roll the dice on an early startup. I was pretty surprised by the uneven terms between founders and early employees. From what I could tell the early employees takes
more risk than the founders because they don't get that magic token dollar turning into their share of the founding equity event and have to pay the fictional valuation of the seed to convert their options. Depending on how hot your startup is that can be a lot of money.
Anyway that ended in tears, but I got what I was looking for from it. A look under the covers of the hot VC backed startup roller coaster. I may be getting old and cynical, but it looked considerably more exploitative than what I saw at Google. Obviously depends on the character of the founders and leaders, but the structure seems to be setup for toxicity.
