Pros
The people are great to work with; everyone is talented, motivated, and friendly. The company has a good set of core values and upholds them. Compared to my previous experience at a larger company, there is relatively little office politics and good amount of transparency. It's also been great to contribute to measurable improvements so quickly. The pace is fast.
Cons
Startups were generally whip-lashed by rising interest rates as VC funding has slowed down, and Ethos hasn't been totally immune to it. There have been some layoffs and some adjustments in strategy, but I think the leadership has handled it all as well as they could, and things appear to be more stable now. The managers at Ethos have quite a bit of experience, which has helped.
