I once worked at a startup that was acquired and the founders made a killing. A few years after the acquisition, they founded a new company in an adjacent domain and started raiding their original company for talent. At the time I was working with a guy who had product and marketing experience who happened to be close college friends with one of the cofounders. No one liked working with this guy. Yet rumor had it that he was offered a 5% stake in the new company while the engineers they were recruiting were being offered .25-.5%. I was very confident that they would be successful but I opted not to work for them because I was so offended by the inequity of the offers. The developers they were attempting to raid also had proven that they were productive and effective so it wasn't as though they were making a wildly speculative bet on them.
I also knew that in a major exit, I would be more resentful of the relative difference between my rewards and that of this other guy than I would have been pleased with my windfall. I had once had serious respect for the cofounders, but their greediness and willingness to perpetuate these systems of inequity permanently diminished my opinion of them.
Yet, I have to concede that the cofounders were correct in their assessment that they could lowball the engineers with little impact on their prospects for success. They were able to exploit their way to a second major windfall, far larger than the first.
