Pros
I've worked for the company for two+ years, and after the merger with Perform, our company has a better grasp on direction. The move from the suburbs to The Loop office was handled extremely poorly, but the current C-level people are much more capable. Stats Perform is now the biggest sports data company and sports AI company in the world, but it also has some of the best people I've ever worked with. I never dread going to work, and the environment fostered in the last year or so is a step up than before. If nothing else, it looks like a highlight on a resume or CV if you'd like to work for a professional sports team someday.
Cons
The hours can be long, especially as a sports company, a lot of nights and weekend work will be normal for a lot of roles in research, editorial, production or engineering. Bonuses and raises are handled on a case-by-case basis and are generally solid, though opening salaries may be a touch light relative to similar non-sports related jobs.
