“Indistinguishable from a human voice.” Synthflow AI raises €17.2M to scale voice AI agents.
Berlin-based startup Synthflow AI has raised €17.2 million to scale its platform for voice AI agents — capable of sounding so natural that they are indistinguishable from real humans.
Synthflow is building next-gen infrastructure for voice automation:
— AI assistants for customer support and call centers,
— voice interfaces for businesses,
— phone agents for orders, bookings, service, and sales.
The technology combines speech synthesis, generative AI, and natural language processing. What makes Synthflow unique is that its agents don’t just speak — they engage in conversations with emotion, nuance, tone, and contextual understanding.
The startup is already working with retail, banking, logistics, insurance, and service industries across Europe and the US. Next up: building a fully autonomous voice operating system for businesses.
Voice AI is no longer just an interface — it’s becoming a true interaction agent. The era of robotic phone menus — “Hello, press one…” — is coming to an end.
