Pros
Peek gives you a lot of autonomy to own your area and make meaningful changes. There isn't the bureaucratic red tape that exists with bigger companies that I have worked for in the past. While there is a lot of work to do and things change fast, everyone is in it together and you really feel a sense of team. I have really enjoyed working for peek in the short time I have been here.
Cons
It's a start up, so there isn't a 401k,tuition reimbursement, and some of the other little perks that come with companies flush with cash. and the to do list is always long. There is never enough time in the day to get everything done and at times you can feel stretched thin. I personally love that environment because there is always something to do and you can always make a meaningful difference each day.
