  • Campaign automation, marketing mail and generative AI require the Business Platinum plan at $42 per user per month
  • Lead routing, sub team hierarchies and enterprise controls are Platinum only
  • Even the Business Gold plan at $29 per user excludes the matching engine and lead capture
  • The concierge service is an add on at $20 per user per month with a $500 monthly minimum
  • Every published rate assumes annual billing
