Autonomous enterprise AI agents and CRM intelligence powered by Salesforce Data 360 and Atlas.
Deconstructs complex queries into multi-step action plans grounded in Data 360, retaining state across days or weeks to complete multi-touch operational workflows with human escalation guardrails.
Configure custom agents, subagents, natural-language instructions, and deterministic guardrails using existing Salesforce Flows, Prompt Builder templates, Apex code, and MuleSoft APIs.
Coordinate specialized subagents across departments and connect securely to external enterprise tools through verified Model Context Protocol (MCP) servers from AgentExchange partners.
Replace rigid telephone IVR trees with low-latency conversational voice agents alongside unified deployments across web chat, WhatsApp, SMS, mobile apps, and Slack.

Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
