Move quicker than email.
Email wasn’t built for project work. Slack Connect was. Get instant feedback from customers, hop on a video call with clients, and get approvals from vendors — right where your team is already working.

Connect securely with outside organizations.
Slack Connect is built on the same security and compliance as Slack itself, so you can work safely with anyone outside your company. You decide what partners can join, what they can see and share.

Catch up on what matters with AI on your side.
Whether you are adding a new teammate to the project and need to catch them up, or need to recall the launch date of a project, AI can help. Find what is important, summarize it, and do it faster than ever before.
