About PolyAI
PolyAI is a European enterprise voice AI company whose agents answer customer service phone calls for large brands. Its Agentic Dialog Platform lets companies build, run and govern dialog agents that handle complex calls such as reservations, billing, outage reporting and card servicing, either through the no-code Poly Agent Builder or an Agent Development Kit aimed at engineers. The agents run on Raven, a proprietary dialog model the company says was trained on more than a billion enterprise conversations, and builders can swap in third-party models such as GPT-5, Claude or Gemini. PolyAI makes money by charging enterprises for agent usage on a per-minute basis, a price that also covers maintenance, monitoring, upgrades and 24/7 support. Spun out of the University of Cambridge in 2017, it serves customers including FedEx, Marriott, PG&E, Caesars Entertainment and UniCredit across 75 languages.
