Synthflow AI is bringing 'conversational' voice agents to call centers. Read the pitch deck that it used to raise $20 million.

Synthflow, a Berlin-based startup, has successfully secured $20 million in funding to enhance its innovative AI voice agents that can engage in natural-sounding conversations with customers. This platform is designed for enterprise clients, allowing them to create and implement AI voice agents without the need for coding skills. The technology enables businesses to customize these voice agents to manage various tasks, including customer support, answering simple inquiries, and facilitating actions like appointment scheduling. Co-founder Hakob Astabatsyan described Synthflow as a no-code voice AI platform that enables companies to quickly and efficiently deploy AI agents tailored to their needs. Differentiating itself from traditional automated call systems, which rely on users pressing buttons to navigate options, Synthflow leverages advanced large language models for real-time contextual dialogues. In a demonstration video, an AI agent interacts with a customer requesting a car insurance quote, maintaining a relaxed and conversational tone while efficiently gathering necessary information before transferring the call to a human operator. Astabatsyan emphasized the technology's rapid response time, with the AI agent providing answers in less than 400 milliseconds—aligning with the human brain's natural processing speed in conversations. Founded in 2023 alongside Albert Astabatsyan and Sassun Mirzakhan-Saky, Synthflow has quickly garnered over 1,000 enterprise clients, primarily in sectors like finance, healthcare, and education. The startup also offers its technology on a white-label basis and seamlessly integrates into existing telephony systems. In the competitive landscape of AI startups, voice technology has emerged as a critical focus area, with other companies such as ElevenLabs and PolyAI also securing substantial investments to develop similar solutions for call centers. Astabatsyan remarked on the challenges of fundraising within the AI sector, noting that investor expectations have risen significantly, with demands for growth rates that are twice the historical benchmarks. The recent Series A funding round, led by Accel with contributions from Atlantic Labs and Singular, has brought Synthflow's total funding to an impressive $30 million. The company intends to use these funds to establish a new office in the U.S. and further advance its agent platform development.
