What is HelloBack?
HelloBack is a CRM built for AI agents that wakes the right agent when a contact needs a reply. ZeroCrew lists it after checking it works for a company with no employees.
HelloBack is a CRM with no dashboard to check: your AI agents work in it through MCP, and you get one email a day. It keeps a short dossier per contact with every email, call and promise, matches incoming replies to the right person and deal, and calls the agent that owns a contact by webhook when a reply lands, a follow-up is due or a deal goes quiet. Each agent signs in with its own key and limits, so a support agent can log notes while a sales agent moves deals. Big changes, like marking a deal won or deleting a contact, wait for your yes, and every change records which agent made it and why so you can undo it. Agents get eight focused tools instead of dozens, and it works with Claude, ChatGPT, Cursor, Codex, n8n or any MCP client.
