Pros
Management is inspiring. They show how incapable you can be but still "have a company". Whether it's successful is another thing, but they really do set how low the bar can be to have your own business.
Cons
Severely underpaid: For how much the CEO brags about how rich he is, one would be wise to observe how little the people around him have. I was paid less than half of market rate. Unbelievably cheap: We're talking posting ads on Craigslist as gigs to avoid paying the $20 job fee listing cheap. Dishonest: We were promised equity stake. I had to beg for something in writing, and got a document plastered with how it wasn't a "legal" document, and provided a share amount, but without providing a percentage of ownership or a number of total shares of the company. Clearly deliberate so that they could dilute it to however they wanted to make sure our shares were as worthless as they wanted them to be. They also couldn't manage to even spell my name right on the document. Hostile: - CEO would be regularly verbally abusive. He even called me after my employment ended to harass me, to which I had to file a police report for. Clearly didn't have parents that taught him any manners. - The COO (head of HR at the time) also called me when I tried to hire an attorney for the harassment, abuse, and work violations while employed and told me that "[The CEO] has a lot of money..." in an undertone that I interpreted that was implying they were going to put a hit out on me for trying to exercise my legal rights. Of course, he also made sure to ask whether I was recording the call before threatening me, since California is a two-party state. In the end, they hired one of the biggest defense firms in the state and conflated things like the CEO sending me home continuously without pay to unpaid time I took to travel during back and forths.
