PolyAI

PolyAI builds enterprise voice assistants that resolve customer-service calls through natural, open-ended conversation rather than rigid menus. Its platform handles high-volume support interactions in more than 45 languages across sectors including banking, hospitality, retail, and telecommunications, integrating with existing contact-center and CRM systems. Customers include FedEx, Marriott, Foot Locker, and UniCredit. Founded in 2017 by Cambridge researchers Nikola Mrkšić, Pei-Hao Su, and Tsung-Hsien Wen, the company is headquartered in London. In December 2025 PolyAI raised an $86M Series D co-led by Georgian, Hedosophia, and Khosla Ventures, with participation from NVIDIA's NVentures, valuing the company at roughly $750M and bringing total funding to over $200M.
