Pros
My experience is that this is a company that cares about it's people - their growth and development, happiness and making sure they have a voice. Not all places walk the talk like this place does and the tone is set by the founder. People are talented, fun and kind. Love the daily 4pm "Tea Time" where all work stops, devices down, and people go to the protected interior garden for a break and connect for 30 minutes. MATTER is clear on who they are and where they are going, the work is stellar, with a combination of innovative start up and Fortune 500 product and service design.
Cons
Good problems - things that come with growing pains: lots of big work, big clients and growth. Sometimes this results in uneven allocation of resources for discreet periods of time. If you are wondering where the negative reviews are coming from, there was a bad apple that had an ax to grind because of poor performance and ethical issues.
