OneAI Acquired by monday.com: What It Means for Voice AI Customers
OneAI's voice AI technology and team are now part of monday.com. Here's what happened in the acquisition, and what it means if you're a OneAI customer or partner.
On May 11, 2026, OneAI's next chapter became public: monday.com agreed to acquire OneAI, taking on our voice AI technology and, through an acquihire, welcoming much of our team into its Work OS ecosystem. Represented by Arnon, Tadmor-Levy, the deal closed as an asset purchase agreement, the kind of transaction that keeps a product's DNA alive even as the company around it changes shape. If you're a OneAI customer, partner, or just tracking the voice AI space, here's what actually happened, and what comes next.
OneAI's road to this moment
OneAI has been building conversational AI for close to four years. We started before ChatGPT existed, exposing proprietary language models as APIs for businesses that needed to clean up, tag, and act on text data. From there we moved into chat agents, and eventually into real-time voice, which became the heart of the product. Along the way we built a full voice-agent stack: a proprietary call-orchestration engine we called the "Director," a tree-structured scripting system for building agent conversations, self-hosted speech-to-text, and a pricing model built around qualified outcomes rather than minutes on the phone. That stack is what monday.com ultimately acquired.
Why monday.com wanted an in-house voice AI engine
monday.com has been racing to build out an AI Work Platform to compete with the AI pushes coming from Atlassian, ServiceNow, and Salesforce. Voice was the missing piece. Until now, voice agent capability meant leaning on outside partners. Acquiring OneAI gave monday.com a production-grade voice AI engine it could own outright: real call volume, multilingual support, and years of tuning on what actually makes an AI phone conversation feel competent rather than robotic.
What happened to the OneAI team
This wasn't a shutdown. It was a relocation. In the weeks following the announcement, a group of OneAI engineers, product, sales, and QA teammates joined monday.com's offices and kept building on the same voice AI foundation, just with a much bigger platform, larger customer base, and deeper resources underneath them. The day-to-day work (improving call quality, expanding language support, tightening the scripting tools) didn't stop. It just changed address.
OneAI's technology lives on as Harmony.ai
Here's the part most people ask about first: OneAI's voice-agent runtime didn't get shelved. It became the technical substrate for Harmony.ai, a new AI voice agent platform monday.com built for revenue teams, covering sales, support, and everything in between. Harmony.ai inherits the parts OneAI customers already trusted: goal-based conversation design, call orchestration, and a multi-language voice stack. On top of that foundation, the Harmony.ai team added a new front end built around CRM-native workflows, campaign and contact management, live call monitoring, and a self-improving feedback loop that turns real call outcomes into better agent scripts over time.
Harmony.ai's brand went public and the platform is now rolling out to its first customers. If you're a OneAI customer or partner wondering where the technology and the people who built it landed, harmony.ai is the place to see it.
