I did 3 stsartups as an early employee. First raised 27M then acquihired, common stock wiped out. Second is still going strong and profitable, my 2 years there will probably net me a few 100k. Third was a home run, my 6 years there made me $10M+ and I now have secondary firms chasing me for a piece. Startups can work, but you need to be really good and get really lucky and not stop after a failure.
