The technology is not ready to scale and hasn't been able to win new customers on a consistent basis. Demand is also lacking.
These technology/demand challenges might be acceptable, especially in a start-up environment if all other things were right. However, the company culture has been detrimental to the majority of people's willingness to embrace these challenges and most people seem to be operating out of fear of leadership rather than motivation.
It's been my experience that there is a major disconnect between the senior leadership club and everyone else, especially with leaderships constant bantering of how great everything is. Facts speak louder than words so I am just one data point but I would imagine any candidate who does their diligence on the turnover the past 6 months might question why?
It feels like most people are being told what to do, rather than inspired to do.
Also, the CEO's backhanded response to another HONEST review is a common MO of not letting people have a voice. As far as the CEOs assertion that there are so many other positive reviews, I might suggest there was a specific edict at the company off-site to have executives write reviews.... This is why the majority of them all happening on two specific days vs osmotically over time as you see on most sites.
