Pros
Worked with many great people across all subsidiaries
Cons
When Thoma Bravo acquired Stamps.com and its subsidiaries, the CEO eventually left, and leadership of the company transitioned to the CEO from one of the subsidiaries. Soon after that, you could only describe the environment as chaotic and unprofessional. Horrible communication, poor decisions leading to wasteful spending... I watched several colleagues in various departments (all from the parent company, Stamps) be essentially relegated to the "rooftop" (remember Big Head from the TV show Silicon Valley?). The current leadership team seems to think it's acceptable to treat people this way. Don't communicate honestly about anything, totally detach from your humanity, and just take away enough of people's work that you hope they get message and quit. If it had just happened to a few people, you might just let it go. Write it off as not really knowing the whole story, try to give the company the benefit of the doubt. But this is a common theme in many reviews for a reason.
