Slack is selling a game-changing product that changes the way that people communicate, get work done and feel belonging at work. The team that the company has assembled is bar none - people truly smart, collaborative, humble and hard-working. I learn from my peers and team every single day, and I am proud to be part of a winning team.

Cons
