Harmony.ai

What is Harmony.ai?

Harmony.ai is a voice AI platform for sales and customer teams. Its agents answer inbound calls, ring new leads shortly after a form submission, qualify them against your criteria, record the outcome in your CRM and book meetings on a calendar. A no-code visual builder is used to compose call flows, prompts, tools and knowledge, test them in live chat and move to production. The platform includes predictive, power and batch dialing, branded caller ID, number-reputation monitoring, IVR and voicemail handling, warm transfers to a person, plus analytics with automated QA on every call. Voice responses are quoted at under 200 milliseconds. Solutions range from AI SDR and speed-to-lead to receptionist, after-hours coverage, collections and tier-1 customer service. On the Pro plan you pay $0.39 per minute of agent time plus a $250 per month platform fee, with up to 3 agents, 10 concurrent calls and 100 calls a day, while Enterprise is custom. The company says it is part of monday.com.
