PolyAI, a leader in enterprise conversational AI, has closed an $86 million Series D funding round co-led by Georgian, Hedosophia, and Khosla Ventures. Participation from NVentures, British Business Bank, Citi Ventures, Squarepoint Ventures, Sands Capital, Zendesk Ventures, and Point72 Ventures brings the company's total funding above $200 million to advance human-like customer conversations.
PolyAI's voice AI agents deliver lifelike interactions at enterprise scale, spanning financial services, healthcare, hospitality, insurance, energy, and retail. Notable customers include Marriott, Caesars Entertainment, PG&E, UniCredit, and Foot Locker.
The technology enables proactive issue resolution and opportunity detection in real time, fostering an interconnected system that supports customers, employees, and AI agents collaboratively.
Nikola Mrkšić, CEO and Co-Founder of PolyAI, outlined the company's vision.
"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, emphasized the strategic value.
"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."
The investment will fuel development of the proprietary Agent Studio platform and expand sales and marketing initiatives, positioning more global enterprises to adopt agentic AI for superior customer experiences.
