Amazing product but starting to get a little political

Pros

Slack is a high-velocity, awesomely creative, friendly place to work, and one of the best jobs I've had. Truly inspired by the dedication to the product and proud to say I'm an employee. I really enjoy: great engineering talent, well-reasoned decisions, a multitude of perks and good balance of right brained thinkers. We have a lot of opportunity in front of us and we're still in the building phase of the company so there is a lot to do and learn professionally and personally.

Cons

Scaling fast is exciting, but experiencing some growing pains along the way. A key leader is being irresponsible with use of power and introducing Yahoo-like politics. I believe some teams suffer from this more than others.

Pros

Incredible opportunity Investment in people, facilities, tools, equipment Passion Values that are reinforced and sincere - not just crap written on a poster

Cons

none yet, just be careful as the company grows so quickly to remain true to roots. That comes from over communicating,

Pros

Wonderful team, worked from home, creative and supportive coworkers, best and most fun game product ever

Cons

Sadly the online MMO is now defunct; that is the only con. Company now exists as Slack Technologies and is doing awesome things for business communications.
