Open

What is Open?

Open (open.cx) is an AI customer support platform built around an agent called Agent 5. It handles inbound support and outbound campaigns across voice, web chat, email, WhatsApp, SMS, social channels and Slack, and hands tickets to a human when needed. It can sit on top of an existing helpdesk such as Zendesk, Intercom, Salesforce Service Cloud, HubSpot or Freshdesk, or run on its own AI-native helpdesk with unlimited agent seats. You train it on documents and knowledge bases, build agentic workflows in a visual editor, and watch every AI decision through observability and evaluation tools. The vendor reports an average automation rate of 77%. Pricing is outcome-based: a rate of $0.75 to $0.90 per resolved ticket depending on monthly volume, with no per-seat, per-message or setup fees, and tickets that the AI hands to a human are not billed. Carrier costs for calls and messages are passed through at cost.
