Slack

Leading enterprise collaboration platform, now integrated within Salesforce ecosystem

Slack Technologies is a business communication platform that revolutionized workplace collaboration through its channel-based messaging system, integrations, and workflow automation tools. Founded in 2013 and launched publicly in 2014, Slack quickly became one of the fastest-growing business applications, serving millions of users worldwide across organizations of all sizes. The platform combines instant messaging, file sharing, video calls, and extensive third-party integrations into a unified workspace designed to replace email and fragmented communication tools. In December 2020, Salesforce announced its acquisition of Slack for approximately $27.7 billion, which closed in July 2021. Since the acquisition, Slack operates as a subsidiary of Salesforce and continues to function as a distinct product and brand. The integration with Salesforce's ecosystem has enhanced Slack's capabilities, particularly in CRM integration and enterprise workflows, while maintaining its core identity as a collaboration platform. While Slack is not traditionally classified as an AdTech company, it plays a role in the broader marketing and advertising technology ecosystem through its use by marketing teams, agencies, and AdTech companies for internal collaboration, client communication, and workflow management. Many AdTech platforms and marketing technology vendors also integrate with Slack to deliver notifications, alerts, and campaign updates directly into team workflows.
