The turnover rate speaks for itself

Pros

If you are a software engineer this is probably a great place to work. There is a lot of room for individual creativity, minimal oversight, and project ownership. Everyone else has a very different experience. One more pro: if you are able to stay for more than a year you will almost certainly be promoted, but mainly due to exceedingly high turnover, not growth.

Cons

The company leadership and interdepartmental relationships are appallingly toxic. Leadership has introduced the workplace philosophy of “radical candor” which so far just seems to be a method for us to publicly criticize each other. Company wide surveys are embarrassingly biased, and there is blatant favoritism. All of this combined leads to an environment that is increasingly contentious, demoralizing, and punitive.

Good potential, but hindered by tops-down culture

Pros

Potential to work for a place with a good opportunity to become an industry leader, or at least go public

Cons

* Company tripled in size after a merger in early 2026, and leadership hasn't yet figured out the necessary new behaviors and processes. * Extremely tops-down culture: Expectations to drop everything and pivot when execs have a random thought that they're too busy to clarify impedes progress towards a healthy "ownership mentality"

Cons

- Fast-paced environment typical of a scaling startup - Some internal processes are still evolving
