Just look at the turnover of talented senior folks on LinkedIn, and it will tell you everything you need to know. A winning startup wouldn't lose talent at that rate.
All the issues stem from the CEO. Cannot take any criticism even when he is completely wrong. Treats people like pawns to fulfill his fantasies of grandeur. Your feelings and well-being mean nothing to him, despite "humanity" being his favorite word. It's all lip service. Deeply hilarious and ironic, given he's the CEO of a workforce development company.
