Overview

Synthflow AI, launched in 2023, builds a no-code voice AI platform aimed at automating common business phone workflows like appointment scheduling, lead qualification, and customer support calls, positioned for teams that want to deploy voice automation without writing custom integration code.

The no-code builder lets a business configure a voice agent's conversation flow, connect it to a calendar or CRM, and go live without engineering support, an approach aimed squarely at small and mid-sized businesses rather than the enterprise contact centers larger voice-AI platforms target.

Pricing runs per-minute for the core voice engine at roughly $0.09 per minute, plus additional cost for language model usage and add-ons. For a small or mid-sized business that wants voice automation for scheduling and lead qualification without hiring a developer, Synthflow's no-code builder addresses that directly.
