Omilia

Omilia is an enterprise conversational AI company that builds voice and chat agents for large-scale customer service, along with voice-biometrics tools that let a caller be identified by the sound of their voice rather than by answering security questions. Founded in 2002 by CEO Dimitris Vassos and based in Athens and New York, Omilia has grown into a long-established player in the conversational-AI space, reporting more than one billion conversations handled across 30 languages for clients including Capital One, Taco Bell, Discover and the UK’s Department for Work and Pensions.

What Omilia’s platform offers

Omilia’s product lineup includes Voice Agents and Chat Agents for automating customer interactions, Authentication Agents built around voice-biometrics verification, and TalkGuard, an anti-fraud tool designed to flag suspicious calls. Together, these products position Omilia as an “agentic” customer-experience platform, a term the industry uses for AI systems meant to carry out multi-step tasks on a customer’s behalf rather than simply answering a single question.

How voice biometrics authentication works

Voice-biometrics authentication analyzes the unique physical and behavioral characteristics of a person’s voice, such as pitch, cadence and pronunciation patterns, to confirm their identity during a call without requiring them to recite a password or answer security questions. Combining voice biometrics with fraud-risk analysis, as Omilia’s platform does, lets a contact center flag a call where the voice doesn’t match the account holder’s enrolled voiceprint, or where other signals suggest the call may be fraudulent, before an agent or automated system proceeds with a sensitive request.

Omilia’s $67 million Series B

Omilia announced a $67 million Series B funding round on August 6, 2026, led by Expedition Growth Capital, to expand its push into the US voice-AI market. The company said its annual recurring revenue had grown more than tenfold since its Series A, surpassing $60 million, reflecting rapid growth as enterprise demand for AI-driven customer service automation has accelerated industry-wide.

Omilia’s long operating history in conversational AI

Unlike many conversational-AI companies founded during the recent generative-AI boom, Omilia has operated since 2002, giving it over two decades of experience building natural-language systems for enterprise customer service before large language models became mainstream. That history has let the company build a substantial base of enterprise clients across banking, retail, insurance and government well before current AI hype cycles began.

Omilia’s competitive position

Omilia competes against both long-established contact-center technology vendors and newer, AI-native conversational platforms, a crowded market shaped by enterprises’ growing push to automate routine customer service interactions while keeping fraud risk low. Its combination of conversational AI with built-in voice-biometrics authentication differentiates it from competitors that offer only one capability or the other, letting a single platform both handle a customer conversation and verify the caller’s identity within the same interaction.
