HubSpot

  • Free tier limited to 2 users and 1,000 contacts; severely restricts growing teams
  • Many advanced features (automation workflows, custom objects, advanced reporting) gated to paid tiers
  • Starter plan at $7/month per seat scales quickly for larger teams (300+ users would cost significantly more)
  • Free tier removes credit card requirement but lacks most enterprise capabilities

Klaus

  • No longer available as standalone product after Zendesk acquisition
  • Requires separate Zendesk subscription (not included in base plan)
  • Cannot be used with non-Zendesk help desk systems
