Pros

They make some great promises to get you in the door! Their marketing and publicity team is REALLY good!

Cons

The culture is horrible, the leadership team does not listen and is not grounded... this has filtered into the employees with zero trust and psychological safety. The salaries are mid-range but the benefits are the lowest I have seen in my career.

Pros

Great at marketing things. Some of the original founders (from Harvard) were technically and scientifically top notch.

Cons

The turnover is very high. Most of the initial team (including top leadership and 2nd level leadership) were let go. There is a lot of internal conflict and distrust as a result. There is a lot of hype that is built around some of the work.
