Pros
I originally was not going to write a review about Mattermark until seeing all of the recent job openings. Want to make sure anyone interviewing with Mattermark has a clear vision of the company, something most of us did not have. Mattermark hires great and talented people, although there has been a mass exodus. Just look at the amount of job openings they have and how recent they all are. I would also guess the 5 star review bellow is written by a founder.
Cons
There have been multiple rounds of layoffs, one where they went through the Account Executives and SDR's a month after hiring many of them, tapped people on the shoulder, took them into a conference room, and fired them while the rest of the sales team sat there watching and wondering who would be tapped next. The founders decided to scale up the sales team without having product market fit so they had a sales team with no product to sell. The founders do not know what they are doing, the CEO held an all hands where she told a company with very low morale that the company would not be acquired, probably couldn't raise more funding, and she was going to run the company into the ground. Terrible leadership and unprofessional. The company peaked at around 60 employees in June/July 2016, now I would be surprised if they have 20. The VP's and the founders clash and lacked communication which made the working environment very hostile, especially when they would loudly argue in the middle of the open office space. Most of the VP's have left the company.
