Slack was a workplace messaging and collaboration company that became part of Salesforce after the acquisition closed in 2021.
Slack built an early lead in team messaging by combining persistent channels, strong search, and a large integration marketplace that made it a central operating layer for many companies. Slack Connect also lets organizations collaborate with external partners inside shared channels rather than relying solely on email.
After the Salesforce acquisition, Slack gained tighter CRM context through Salesforce integrations and Agentforce, while its AI features add summaries, enterprise search, and in-conversation agent workflows across existing team data.

Enterprise collaboration remains a large and competitive market as Microsoft Teams, Google Chat, and open-source alternatives continue to compete for workplace messaging share. Slack is positioned as Salesforce customer-360 collaboration layer and an agentic operating system for AI-assisted work.
Slack continues to ship frequent product updates focused on AI agents, workflow automation, and deeper Salesforce integration, suggesting the platform will remain a strategic growth surface within Salesforce rather than a standalone public company.
