Slack
Slack · Communication
Business messaging built around channels and workflows, acquired by Salesforce for $27.7B in 2021. Positioned as the alternative to email threads for team communication. Distinctive for its integrations depth (2,500+ apps) and the way it exposed how much internal knowledge lives in messages. Priced per ACTIVE user (not per seat) — inactive users don't bill, but active-member spikes surprise finance teams. Salesforce raised Business+ tier from $12.50 to $15/user in 2026 to fund AI features.
In other words, Slack is worth it for teams of 20+ that live in channels and need deep integrations with Salesforce, Google Workspace, or Zapier's 8,000+ apps. Pro covers most teams; Business+ unlocks SSO. Setup is instant, but channel discipline is a real skill. Best-in-class app directory (2,600+ integrations). Downside: gets expensive fast past 100 users, notification overload is the top pain point at scale, and Business+ went up ~20% in July 2026.
