Pros
I started at SeriousFun within the last year and I regularly tell people who ask that I wish I had made the move to this organization even sooner. I was very cautious and selective when considering leaving my former job, which I loved. Some of the Glassdoor reviews for SeriousFun, as you can see, didn't paint it in the best light. When I began the interview process, it quickly became obvious to me that this was not the organization described by some of the more negative reviews. Still cautious, I was offered and accepted the job here, and I can honestly say that I haven't had a mediocre, nevermind bad, day yet. My colleagues are super bright, they work hard, and they are very passionate about the mission and about helping to maintain and increase the very positive office/organizational culture here. Leadership, especially the CEO (now in his fourth year), is more collaborative, creative and open to feedback than I have experienced at any of my former employers. The issues noted in previous reviews, while perhaps valid to some extent, seem to have been resolved or are on their way to being resolved.
Cons
Not so much a con, but a challenge...SeriousFun is a small nonprofit organization with limited resources. Leadership and staff members must be creative in their approaches to problem-solving, and also be willing and able to wear multiple hats at times. This works well and fits for me and many of my colleagues here, but it is certainly something to think about if you are considering working at SeriousFun.
