Pros
Fantastic culture, great people, supportive work environment, management is uniformly good to work for and with, and the job is not a grind. Don't believe the negative reviews on here - the vast majority of employees LOVE working here. You can find a few unhappy and angry people at the best companies there are - they just happen to be the ones who usually post on a site like GlassDoor. I've worked at several good companies in Silicon Valley, and Jotform is by far the best place I've ever worked - virtually all of my colleagues say the same thing.
Cons
None, except for having to work with a few entitled people who wouldn't be happy anywhere and want the rest of us to join them in their negativity.
