Pros
FastSpring an effective and profitable, well-established startup of 50 or so employees with a SaaS offering at the intersection of payments, subscriptions and e-commerce. As the company was understaffed for many years before acquisition by current leadership there is there is a lot of opportunity for out-sized impact and accelerated growth in all areas of the business. Employees are treated as experts in their fields, feedback is heard, experimentation is encouraged, failure is not dwelled on.
Cons
Though profitable, this is after all, still a start up. Process is being developed, grooves are being found, not all experiments are successful, some "departments" are filled by team effort (like IT or HR). If you are a team player and like solving problems these are less like con's and more like engaging challenges.
