In a major step forward for voice-based enterprise automation, Berlin-based startup Synthflow AI has raised $20 million in Series A funding. Led by Accel with support from Atlantic Labs and Singular, the round positions Synthflow as a frontrunner in real-time conversational voice agents.

A New Standard in Voice AI

Synthflow’s no-code platform enables businesses to build natural, human-like voice agents that handle customer interactions—like appointment booking and support—with just 400ms response latency. This allows for seamless automation of workflows in sectors such as healthcare, education, and finance.

By abstracting the complexity of telephony, NLP, and voice synthesis, Synthflow empowers teams to deploy scalable voice experiences faster and without engineering overhead.

Global Expansion and Product Evolution

With its latest funding, the startup plans to expand into the U.S. market, grow its engineering team, and further optimize the platform’s latency and multilingual capabilities. Synthflow’s voice agents are already seeing adoption across Europe in high-volume call centers, where AI accuracy and real-time interaction are critical.

As enterprises look to automate without sacrificing human warmth, Synthflow delivers an AI-native alternative to outdated IVR systems.

Implications for Tech Leaders and Investors

For CIOs, support heads, and enterprise architects, Synthflow represents the next evolution of AI-powered engagement. As businesses seek high-touch automation, real-time voice AI is emerging as a strategic advantage—not just a cost saver.
