PolyAI
Enterprise voice AI platform for contact centers, focused on production phone agents with conversation design, maintenance, and industry deployments.
Contact centers and CX teams that want production phone agents with vendor-led conversation design and ongoing maintenance.
Startup product teams that only want a developer SDK and published per-minute DIY meters.
Verdict
PolyAI is a good fit when the buying question is a reliable phone agent in a live contact center, not a weekend prototype. Public revenue signals land toward the upper end of this directory's mid-market band. Practitioners like production voice quality; engineering-led teams that want to compose every model hop may still prefer Vapi-style platforms.
