Product overview

The platform handles both inbound customer support calls and outbound calls (sales, appointment scheduling, lead qualification), making it a broad voice automation tool used primarily by BPO firms and contact centers. Agents built on Synthflow conduct natural phone conversations, detect intent, perform actions (such as booking appointments or transferring to humans), and operate around the clock. The platform has processed over 45 million calls and claims to answer 35% more calls than human-only teams. Founded in 2023, Synthflow has raised approximately $30M in total, including a $20M Series A in June 2025 led by Accel, with Atlantic Labs and Singular.
