Market Position
Leading enterprise communication and collaboration platform, now part of Salesforce ecosystem
Overview
Slack is not an AdTech company. It is a business communication and collaboration platform that provides messaging, file sharing, and workflow automation tools for teams and organizations. Founded in 2013 and launched publicly in 2014, Slack revolutionized workplace communication by offering an alternative to email with organized channels, direct messaging, and extensive third-party integrations. The platform became one of the fastest-growing business applications in history. In December 2020, Salesforce acquired Slack for approximately $27.7 billion, integrating it into Salesforce's Customer 360 platform. While Slack itself is not part of the advertising technology ecosystem, it serves as a collaboration tool used by many companies across industries, including those in AdTech. The platform's value lies in improving team productivity, centralizing communication, and integrating with thousands of business applications rather than facilitating advertising operations or media buying.
