PolyAI answers the phone. While most of this directory started with chat and added voice later, PolyAI has been voice-first since three Cambridge machine-learning PhDs, Nikola Mrkšić, Pei-Hao Su, and Tsung-Hsien Wen, founded it in London in 2017 out of the university's Machine Intelligence Lab. Its agents are known for sounding genuinely human and for surviving the things that break lesser systems: interruptions, accents, background noise, and callers who change their mind mid-sentence. Restaurants, hotels, banks, and utilities use it to answer every call instantly, day and night, with customers like PG&E, UniCredit, Golden Nugget, and Fogo de Chao on the roster.

The platform matured into what the company calls an agentic dialog platform: Agent Studio for building and managing agents without code, a developer kit for deeper work, and Raven, a proprietary conversation model trained on more than a billion enterprise conversations. Compliance boxes (SOC 2, HIPAA, PCI) are ticked, which matters because taking payments and health information over the phone is exactly where voice AI earns its keep.

Investors have noticed the wedge. In December 2025 PolyAI raised an $86 million Series D at a valuation around $750 million, with NVIDIA's venture arm participating, bringing total funding past $200 million. Commercially it bills on usage, priced per minute of conversation, with rates scoped to your call volume rather than published on the site.

Choose PolyAI when the phone is your problem. If most of your support pain is hold music, missed calls, and staffing the night shift, a voice-native specialist will beat a chat-first platform's bolted-on telephony, and PolyAI is one of the most proven voice specialists in the market.
