Company OS vs. Slack: Communication Hub or All-Encompassing Work OS?

Slack is the gold standard for team chat — but chat doesn't run your business. You still need project management, CRM, HR, invoicing, and more. Company OS includes messaging and 51 other tools.

Slack — strengths

  • Clean, focused UI
  • Wide ecosystem of integrations
  • Mature templates and workflows

Slack — limitations

  • Only solves one problem — you'll still need a CRM, finance, HR, etc.
  • Per-user pricing adds up fast across the team
  • Limited native AI

Verdict

Slack at €9/user/mo seems affordable — until you add all the tools you actually need to run a business. Project management, CRM, HR, invoicing, contracts, time tracking, and more can easily cost a 10-person team €1,000+/mo. Company OS gives you team communication AND everything else for €99/mo flat.
