Pros
It was a great learning experience on running a tech startup. Really appreciated the casual work environment conducive to productivity, I got to bring my dog with me to work, and there were mostly great staff & colleagues--some of whom have become close friends. CEO and I had pretty good rapport, but his being away often made too many of the mice play, so to speak. They've recently (in 2019) really turned the company around and the software is finally competitive with the top booking SaaS in the US market. Knowing who's steering the ship now, it's become a whole new company with clear direction and focus.
Cons
Lack of accountability and integrity by many of the upper management back in 2017. Long hours. Excessively high turnover with little or no warning. Below-market pay.
