What is Synthflow?

Synthflow is an all-in-one platform that leverages cutting-edge voice ai to automate phone calls for customer support, lead qualification, bookings, FAQs, and more. It replaces live agents for routine tasks while integrating seamlessly with your existing telephony and CRM systems. Designed for enterprises yet accessible to smaller teams, Synthflow blends natural language processing, low-latency voice responses (under 500 ms), and strict compliance to deliver human-like phone interactions without manual intervention.

Today, over a hundred clients trust the platform to manage tens of thousands of calls monthly, backed by SOC 2, HIPAA, and GDPR compliance.
