Generous free plan (unlimited recordings, 5 AI summaries/month) makes it popular with individual users. Paid tiers: Premium ($20/mo, $16 annual) for unlimited summaries, Team ($19/$15), Business ($34/$25) for CRM sync (Salesforce, HubSpot). 90-day money-back guarantee on paid plans. | 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. |
