  • We have 8.8M+ app installations with 155,000 weekly active developers building on the developer platform.
  • 90% of our paid teams on Slack actively use apps.

Slack has a positive, diverse, and supportive culture — we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative.
