Pros

smart people great mission standout pipeline of projects

Cons

disorganized scope across teams increasingly toxic work culture eroding good will - coming from the top down (finger pointing, name calling, last minute requests, unclear understanding of asks, occasional outbursts/yelling at people on calls) overworked incentives misaligned between private equity, management, and individual contributors

Positive culture but CEO's style is problematic

Pros

Company culture is generally positive. Lots of smart people.

Cons

Many are overworked and Cliff Graham, CEO, is reminiscent of a 1950’s advertising executive complete with constant sports analogies and grandstanding while belittling his workforce.
