PolyAI vs Sistava
PolyAI builds an Agentic Dialog Platform for enterprise voice: AI agents that answer real phone calls for reservations, account questions, and routine transactions, powered by its own Raven speech model trained on over a billion enterprise conversations. It sells into large regulated industries, healthcare, financial services, hotels, retail, with SOC 2, HIPAA, GDPR, and PCI DSS compliance built in. Sistava's voice capability is different and earlier stage today: a listen-only Meeting Attender that joins calls and takes notes, with two-way voice and phone channels still on our roadmap. If live phone answering at volume is the job, PolyAI is built for exactly that.

Why choose Sistava as an alternative to PolyAI
- Sistava is a full AI workforce: one hire covers chat, email, browser work, and thousands of app integrations, not just a phone line. PolyAI is a voice specialist that stops at the call.
- Sistava has published self-serve pricing ($25-$200/mo). PolyAI is enterprise-only: no public pricing, a demo and custom quote required.
- Honest concession: PolyAI's live, production phone voice agents, handling real inbound and outbound calls today for healthcare and hospitality companies, is a real capability Sistava does not have yet. Our voice and phone channels are on the roadmap; today the closest is a listen-only Meeting Attender.
