About PolyAI

PolyAI was founded in 2017 in London, UK, by a team from Cambridge University's dialogue systems research group. The company builds enterprise-grade voice AI assistants that handle customer service phone calls with human-like conversation quality—going beyond simple IVR menus to conduct full, natural conversations. PolyAI's voice assistants can handle complex multi-turn conversations, understand accents and dialects, manage interruptions, and resolve customer queries without human intervention. The technology is used by major enterprises to automate their contact centres, handling tasks like booking management, order tracking, account inquiries, and technical support. The company raised $86 million in Series D funding in December 2025, bringing total funding above $200 million. Investors include Georgian, Hedosophia, Khosla Ventures, Nvidia NVentures, and the British Business Bank. PolyAI's certification posture is exceptionally strong: ISO 27001, SOC 2 Type II, HIPAA, and PCI DSS. This breadth of certifications reflects the enterprise focus—contact centres in healthcare, financial services, and retail require these standards. The PCI DSS certification is particularly notable for handling payment-related conversations. As a UK company, PolyAI operates under post-Brexit UK GDPR with EU adequacy. The UK Investigatory Powers Act applies similarly to the US CLOUD Act. Cloud infrastructure is enterprise-grade and multi-region, with deployment options to suit customer requirements. For European enterprises seeking to automate contact centre operations, PolyAI offers a UK-based alternative to US voice AI providers with comprehensive security certifications and proven enterprise deployment experience.
