PolyAI raised US$86 million in Series D funding, PolyAI said on 17 December 2025. The round was co-led by Georgian and Hedosophia, according to the company blog.
Voice AI for customer service has moved from pilots to production queues in banking, travel and retail. Capital concentrates on vendors that can show containment rates and integration into existing contact-centre stacks.
London-based PolyAI has sold enterprise voice agents into those verticals. Series D extends runway as larger platform vendors bundle rival assistants.
Contact-centre buyers should weight live production metrics and language coverage over fundraising headlines when shortlisting voice AI.
