Slack represents one of the most explosive revenue compounding narratives in modern enterprise software. Bootstrapped from the ashes of failed gaming startup Tiny Speck, Slack launched publicly in 2014 and reached $100 million in ARR in just 2.5 years—one of the fastest SaaS growth curves in history. After raising over $1.2 billion in venture capital from Andreessen Horowitz, Accel, and Social Capital at a $7.1 billion valuation, Slack completed a direct listing on the New York Stock Exchange (NYSE: WORK) in June 2019 at a $19.5 billion market valuation. In December 2020, Salesforce announced an agreement to acquire Slack for $27.7 billion in cash and stock (closed July 2021). Under Salesforce, Slack grew annual revenue past $1.5 billion in 2023 and surpassed an annualized run-rate of $1.8 billion ($1.8B+ ARR) in 2026.
