The team commercialized their internal tool as Slack, moving from the volatile gaming market into high-retention enterprise software. This decision saved the company from dissolution and created a new category of workplace communication software.
2013 — Public Launch
Slack launched publicly, gaining rapid traction in tech hubs through a product-led growth strategy. Its channel-based system offered an alternative to fragmented email, demonstrating that enterprise software could achieve viral, consumer-like adoption among high-performing teams.
2014 — Rapid Growth Phase
Slack reached millions of daily active users, securing substantial venture funding and a multi-billion dollar valuation. This rapid scaling established Slack as the fastest-growing enterprise SaaS company at the time, leading legacy competitors like Microsoft to re-evaluate their communication strategies.

It was acquired by Salesforce in 2021 for $27.7 billion to serve as the 'Digital HQ' for the enterprise.
Q: Why did Slack become so popular so quickly?
Slack's growth was driven by its 'Product-Led Growth' model, where teams adopted the tool for free without initial IT approval.

Q: How does Slack make money?
