Pros
Anaplan has been through a tremendous amount of change over the past 3 years, and it has not been the easiest environment for employees. However, the current leadership team set a solid strategy and has been successfully pushing the company forward. It continues to be an incredibly fast-paced environment - if you're looking for a lot of work-life balance, this is not the place for you - but the amount of work to be done means there is plenty of opportunity for you to raise your hand, try something outside of your job description, etc. There is a lot of momentum in the business - it should be a wild (but exciting) few years!!
Cons
There is not a lot of opportunity to grow as a leader (from a people-manager perspective] because of the nature of the business being so focused on profitable growth. There is a lot of work to be done, so it can certainly feel overwhelming at times - but it's also the nature of the PE-backed SaaS landscape.
