I joined a startup wholly-owned by GOWEX 5 months ago. A startup that is now defunct.
I know it sounds crazy but we all believed those numbers, we were happy, money everywhere.
But from time to time one of my mental alarms would go off, and I would just ignore it. "What could possibly be wrong with this company? It's a publicly-traded company, after all."
The moral of the story is: pay attention to your instincts.
