Platform for creating and deploying lifelike voice AI agents for customer interactions and automated conversations.
PolyAI is an enterprise Voice AI platform that deploys lifelike conversational agents for customer service across voice, chat, and SMS channels, with custom enterprise pricing tailored to call volume and use case. It is built for large contact centers in industries such as hospitality, healthcare, banking, retail, and logistics that need to automate millions of customer conversations without sacrificing brand voice or compliance.
Founded in 2017 by Cambridge University PhDs Nikola Mrkšić, Tsung-Hsien Wen, and Pei-Hao Su, PolyAI has grown into one of the most well-funded conversational AI vendors, raising over $120 million in venture capital, including a $50 million Series C in 2024 that valued the company near $500 million. The platform's Agent Studio lets enterprises build a single voice agent and deploy it omnichannel — across phone, web chat, and SMS — without rebuilding for each channel. Documented customer outcomes include Fogo de Chão attributing $7.2M in incremental revenue to a single voice agent, Howard Brown Health citing CSAT lifts from day one, a global delivery company resolving 50% of calls without a human, and a retail clothing brand cutting seasonal hiring by amounts that saved over $1 million.
Based on our analysis of 870+ AI tools, PolyAI sits at the high-control, enterprise end of the Voice AI category, contrasting with self-serve tools like Vapi, Retell AI, or Bland AI that target developers building agents from scratch. PolyAI ships out-of-the-box integrations with Salesforce, NICE, Genesys, Twilio, and other contact-center stacks, supports dozens of languages (including production deployments in Croatian for Zagrebačka banka), and includes Smart Analyst for conversation intelligence plus enterprise-grade policy, escalation, and compliance controls. Compared to the dozens of other Voice AI tools in our directory, PolyAI is the one most often shortlisted by Fortune 500 contact centers that need a managed, white-glove deployment rather than a DIY API.

PolyAI's no/low-code builder for designing a single conversational agent that runs across voice, chat, and SMS. Teams define flows, policies, and escalation rules once, then deploy omnichannel without separate engineering tracks. It is the primary surface non-developers use to maintain agents post-launch.
PolyAI's voices are repeatedly cited by enterprise buyers (Audibel, Howard Brown Health) as sounding like internal agents rather than robocalls. The platform supports dozens of languages including production deployments in Croatian, allowing brands to localize without operating separate regional agents.
Built-in analytics that track containment, CSAT, AHT, and resolution rates across every interaction. Smart Analyst surfaces what customers are actually asking for and where the agent is failing, turning the voice channel into a continuous source of product and CX insight.
Native connectors to Salesforce, NICE, Genesys, and other CCaaS/CRM platforms let agents read and write customer data with no custom development. This reduces typical contact-center AI deployment timelines by removing the longest pole in the integration tent.
Administrators can set policy guardrails, enforce escalation rules, and meet compliance requirements with enterprise-grade controls. This 'unlimited scale with complete control' positioning is PolyAI's main wedge against more developer-focused voice AI APIs that offload governance to the customer.
