About One AI
One AI, operated under the Harmony.ai name, provides AI voice agents that handle inbound and outbound business calls. According to the company's homepage, the agents connect to a CRM and calendar system to qualify leads, book meetings, follow up with prospects, send renewal and payment reminders, and handle retention calls across the customer lifecycle. The platform also includes an AI dialer for outbound calling and IVR navigation for inbound calls.
The homepage describes no-code setup and states that every call is recorded and saved. It also makes performance and security claims, including sub-200ms response times, 100% compliance, and SOC 2 Type II certification. These are the company's own statements and are not verified in this entry. Pricing is not published in the source material.
