What is Harmony?
Harmony, launched October 19, 2026 by monday.com, is a voice AI platform built for enterprise sales teams. Instead of one general-purpose model, Harmony runs a suite of small, task-specific language models — one for qualifying leads, one for capturing data, one for handling objections — orchestrated by a real-time predictive engine. The company claims about 200 milliseconds of audio-in to audio-out latency, speech rhythm it says is indistinguishable from human, and contact rates of up to 70%.
Harmony runs the full sales cycle: prospecting, discovery, qualification, pitching, and warm transfers to live reps with a full briefing. It includes predictive and power dialing, unlimited phone numbers with branded caller ID, inbound routing, and native CRM write-back for HubSpot, Salesforce, Zoho, and Pipedrive, all built on Twilio telephony. One early customer, UK broker Bright Car Finance, says Harmony helped it close 9% more deals in less than a year. Agents identify themselves as AI by default, and customers can configure disclosure, consent, recording, and audit controls.
