Everything you need to ship
One platform, every primitive. Replace a half-dozen tools and ship in an afternoon.
Channels for every topic
Organize work into dedicated spaces — by team, project, or client — so the right people see the right information without inbox overload.
Threaded conversations
Branch into a thread to dive deep without derailing the main channel. Skim a summary later or jump into the full discussion.
Huddles and clips
Spin up an audio call inside any channel with one click. Send a 2-minute screen recording instead of writing a 20-line message.
Slack Connect
Work with vendors, partners, and customers in shared channels. No more cross-company email chains — just one persistent conversation.
Workflow Builder
Automate routine processes — PTO requests, on-call rotations, deal handoffs — with a drag-and-drop builder. No code required.
2,600+ integrations
Bring tickets from Jira, customer feedback from Salesforce, and CI status from GitHub into the channels your team already lives in.
Unified dashboard for everything you ship
Get a complete view of your business with real-time reporting, automated reconciliation, and actionable insights — all in one place.
