Positioning	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.	Video conferencing that displaced WebEx and GoToMeeting through better free-tier quality and simpler UX. Scaled from 10M to 300M daily meeting participants during COVID. Now bundling AI Companion into paid tiers to defend against commoditization from Google Meet (free) and Microsoft Teams (bundled with M365). Priced per host, not per participant. Best free tier in the category if you can live with 40-minute group meeting caps.
