Pros
I have seen the company grow as an employee from less then 20 to now over 80 people. Having been in several small companies previously, the team is doing well given the rapid growth and moving into multiple new regions. The leadership is investing heavily in managers and putting better systems in place for education and benefits. They have a good sense of the org's pulse. Once issues get raised, they do get addressed - not always as fast as we'd want but there is usually a good explanation for not acting or necessary delays. The entire leadership team is approachable and willing to consider input.
Cons
The fast growth has been difficult given all the new faces and separation/specialization of roles. In parallel, there are lots of new systems/processes that are now in place (versus the good old days of just making stuff happen). If you are strictly a start up junkie, Wiserg is clearly now beyond that flexible freedom.
