Slack

One of the leading workplace messaging and collaboration platforms globally, now integrated into Salesforce's enterprise ecosystem as a flagship product

Slack is a leading business communication and collaboration platform that enables teams to organize conversations into channels, share files, integrate third-party tools, and communicate via direct messaging and video calls. Originally launched in 2013 by Stewart Butterfield and team as a pivot from a gaming company called Tiny Speck, Slack rapidly became one of the fastest-growing enterprise software products in history, transforming how organizations communicate internally and with external partners. Slack's platform supports thousands of integrations with tools like Google Workspace, Salesforce, Jira, Zoom, and many others, making it a central hub for workplace productivity. Its freemium model allowed it to penetrate organizations from the bottom up, gaining massive adoption across startups, mid-market companies, and large enterprises alike. By the time of its 2019 direct listing on the NYSE, Slack had millions of daily active users and billions in revenue. In 2021, Salesforce completed its acquisition of Slack for approximately $27.7 billion, one of the largest software acquisitions in history. Slack continues to operate as a distinct brand and product under Salesforce's ownership, serving as a core component of Salesforce's Customer 360 platform. The integration with Salesforce has deepened Slack's enterprise positioning, with features like Slack Connect enabling cross-organizational collaboration and Slack Canvas providing persistent, structured information sharing alongside conversations.
