Is Slack Worth It?

Slack Pro is worth it for any team that needs full message history and group video calls. The jump from free to Pro is the most impactful upgrade. Business+ is only necessary for organizations needing SSO, compliance features, and guaranteed support SLAs. Enterprise Grid is for massive companies with multiple divisions needing separate but connected workspaces. For most teams under 50 people, Pro is the sweet spot.
