According to its own site, Harmony grew out of monday.com: while building monday CRM, the team observed that a company's highest-stakes conversations still happened by phone, with a limited number of people available to take them. To address that, monday.com acquired oneAI.com, a team focused on production voice AI and telephony, and merged the two groups into Harmony AI. Harmony describes itself as "a monday.com company."
The platform's stated use cases include lead qualification, appointment setting synced to a calendar, structured discovery calls, taking a deal from pitch to signature, re-engaging dormant pipeline, renewal outreach, upsell and cross-sell calls, payment reminders, and win-back calls for at-risk accounts. Harmony says its agents integrate with CRM systems (it names Salesforce, HubSpot and Monday.com) to log call outcomes automatically.
Other capabilities described on the site include smart call routing and IVR navigation, an AI-driven outbound dialer (predictive, power and batch dialing), branded caller ID, and per-call analytics and QA scoring. Harmony also describes an internal assistant it calls Siena for building and editing agent behavior through a visual canvas, and a feedback loop in which recorded calls are reviewed for objections and drop-off points, with A/B-tested changes before rollout.
Harmony markets pre-trained compliance baselines and vocabulary for specific industries, including healthcare, finance, real estate, insurance, SaaS and e-commerce, and lists SOC 2, GDPR, HIPAA and ISO 27001 among its compliance certifications and standards. It cites a case study with Bright Car Finance describing increases in business volume, contact-answer rate and conversion rate from deployed voice agents, presented as the company's own reported results.
Pricing is usage-based: a PRO plan is billed at $0.39 per minute of agent time plus a $250 per month platform fee (rate varies by voice model, with a separate custom implementation fee), covering up to 3 agents, up to 10 concurrent calls and 100 calls per day. An Enterprise tier offers custom pricing, unlimited agents, custom concurrency and volume, hot transfers, and API and MCP access.
