Synthflow is run by AgentFlow AI GmbH in Berlin. The platform covers inbound and outbound calls, has a no-code designer and states more than 65 million calls a month in over 30 countries.

That takes Synthflow off the table for small businesses, and keeps it a serious option for large outbound and call centre projects.

- Entry via demo and sales. A standard term is not published.
