Pros
The work environment at HubSpot is like no other I have experienced before or seen since. The company has a pulse unto it's own, with a constant drive toward success. In fact the #1 reason to work at HubSpot is to experience first hand an executive team with a near flawless execution of creating one of the fastest growing companies and take it public. HubSpot was also one of the more transparent companies I have known. Management did a great job of sharing the goals of the company and was extremely successful making sure the employees were aware of what they needed to do to help achieve those goals.
Cons
With a company so driven toward success, it became apparent that the numbers were more important than the people. So in order to succeed at HubSpot you must constantly succeed or live in fear that you will soon be replaced. So don't even consider working at HubSpot if you arent up for the challenge...
