PolyAI, an enterprise conversational AI company focused on automating customer interactions, has raised $86 million in Series D funding in a round co-led by Georgian, Hedosophia, and Khosla Ventures. Additional participants include NVentures (NVIDIA’s venture capital arm), British Business Bank, Citi Ventures, Squarepoint Ventures, Sands Capital, Zendesk Ventures, and Point72 Ventures.
The new financing brings PolyAI’s total funding to more than $200 million, as the company looks to expand deployments of its voice-based AI agents across large enterprises. PolyAI said it now serves more than 100 enterprise customers with over 2,000 live deployments spanning 45 languages and 25 countries, across financial services, healthcare, hospitality, insurance, energy, and retail.
PolyAI is positioning its software as a way for enterprises to handle high volumes of customer contacts with more natural, human-like conversations while maintaining reliability and control expected in regulated and high-stakes environments. The company said its “agentic AI” is already doing work equivalent to more than 1,000 full-time employees at multiple enterprises, and it estimates its agents generate about $1 billion in total value each year across its customer base.
PolyAI also pointed to third-party research on business impact. Citing a Total Economic Impact study by Forrester, the company said customers achieved a 391% return on investment, including average savings of $10.3 million, alongside improvements in customer and employee experiences and stronger operational insights.
With the Series D proceeds, PolyAI said it will further develop the proprietary technology behind its Agent Studio platform and expand go-to-market efforts, aiming to help more global enterprises adopt what it describes as an “agentic” operating model for customer service.
KEY QUOTES:
“PolyAI started with a simple idea: enterprises should sound human,” said Nikola Mrkšić, CEO and Co-Founder of PolyAI. “We turned that idea into reality, and it led to something far greater: the emergence of the agentic enterprise. This is a living, breathing system that understands what your customers, employees, and AI agents are doing in real time — and helps them all succeed together. Like seeing a single drop of water and fixing a leak before it bursts, the agentic enterprise can detect and respond to problems and opportunities before human agents even know they exist. We’re building this future with the world’s leading enterprises, where our AI helps millions of customers every day.”

Emily Walsh, Lead Investor at Georgian and a returning investor through three consecutive rounds, added: “For the world’s largest brands, customer service is no longer just a cost center, it’s a massive opportunity for value creation. PolyAI’s ability to deploy lifelike voice agents at enterprise scale unlocks significant savings and revenue. We believe that PolyAI is building the category-defining platform for customer service in the AI era, and we’re excited to co-lead this round.”
