About Slack

Empathy. Courtesy. Playfulness. Craftsmanship. Solidarity — these are some of the values we live by, as a company. We work by them, too: we’re building a platform and products we believe in — knowing there is real value to be gained from helping people, wherever they are, simplify whatever it is that they do and bring more of themselves to their work.

We’re building a strong, diverse team of curious, creative people who want to find a purpose in their work and support each other in the process. We work hard and we play to win… within normal business hours. And then we go home.

That balance is important: It enables us to truly do the best work of our lives. As a result, we create a place where all kinds of work happens — and happens well — all while working alongside people we respect and admire.
