// WOWLS ASSESSMENT
Slack reached 12 million daily active users and $900 million in annual revenue by 2020, but Microsoft Teams surpassed Slack's user count within two years of launch by leveraging existing enterprise licensing. Slack's direct listing in 2019 at $19.7 billion valuation gave way to declining growth as Teams captured new remote work customers during COVID-19. The Salesforce acquisition at $27.7 billion in December 2021 represented a 41% premium to Slack's trading price but also an admission that standalone collaboration software cannot survive when bundled free by a platform monopolist. Slack now operates as a Salesforce product integrated into Customer 360, serving customers who already pay for Salesforce CRM rather than competing independently for enterprise collaboration budgets.
// WHY WOWLS HUNTS THIS
The acquisition price validated Slack's peak private valuation but also confirmed that no standalone collaboration tool survives contact with Microsoft's bundling strategy. Slack is now a feature inside Salesforce, not a company.
VERDICT: ZOMBIECORN — SALESFORCE PAID $27.7 BILLION TO ACQUIRE A PRODUCT THAT COULD NOT BEAT FREE, WHICH IS ANOTHER WAY OF SAYING MICROSOFT KILLED SLACK WITHOUT SPENDING A DOLLAR ON PRODUCT DEVELOPMENT
