Toolglade’s take

PolyAI is a genuinely capable enterprise voice-AI vendor with marquee customers and strong funding, but it is not a tool you evaluate on a weekend. Pricing is custom, usage-based, and typically lands in six figures per year, with no free tier or self-serve signup. If you run a large contact center and can commit to a build-and-tune engagement, it is a credible option; if you are a small business or want to experiment cheaply, look elsewhere.

About PolyAI

PolyAI is an enterprise-grade conversational voice AI that answers inbound customer phone calls in natural language, handling tasks like bookings, billing, and authentication across 45+ languages. It is custom-built per customer, sold through a sales-led motion with usage-based pricing, and used by large brands in hospitality, banking, and utilities. There is no free tier, making it a fit for enterprises with significant call volume rather than small teams.

PolyAI is a London-founded company that develops branded, custom-built voice assistants for large contact centers. Its agents answer inbound phone calls, understand naturally spoken requests (including interruptions and accents), and complete tasks like booking reservations, handling billing questions, or authenticating callers. The company positions itself around resolution rates and natural conversation quality rather than scripted IVR menus. The platform is aimed squarely at enterprises in sectors such as hospitality, banking, utilities, and retail. Named customers have included PG&E, Marriott, Caesars, Golden Nugget, UniCredit, and FedEx. By late 2025 PolyAI reported more than 100 enterprise customers, thousands of live deployments, and support for 45+ languages. Each assistant is bespoke, built and tuned by PolyAI's team in partnership with the customer. Pricing is custom and usage-based, metered primarily by call minutes, with no free tier or public rate card. This makes PolyAI a serious procurement decision rather than something a small business signs up for. In December 2025 the company raised an $86 million Series D, pushing total funding past $200 million at a reported $750 million valuation.
