Berlin-based Synthflow AI has secured $20 million in Series A funding led by Accel, with participation from Atlantic Labs and Singular (these two are existing investors in the company). This investment brings Synthflow's total raised funds to $30 million and will help the company's enterprise voice AI platform in its mission to accelerate democratic access to conversational AI technology.

Founded in 2023 by serial entrepreneurs Hakob Astabatsyan, Albert Astabatsyan, and Sassun Mirzakhan-Saky, Synthflow addresses a critical gap in the $159 billion customer service market. The company's no-code platform enables non-technical business users to rapidly deploy advanced voice AI agents, a possibility that previously required specialized teams and lengthy implementations.

The startup has achieved impressive traction, serving over 1,000 customers and processing 45 million calls with a 99.9% uptime. Synthflow's voice agents have saved over 5 million hours of contact center operations while answering 35% more calls than non-AI operators.

What sets Synthflow apart in the crowded conversational AI space is its enterprise focus: the company offers HIPAA and GDPR compliance alongside more than 200 integrations with platforms like Salesforce and HubSpot. The company grew 15x in 2024 and maintains over 90% enterprise customer retention.

The fresh funding will fuel global expansion, including opening a US-based office, and accelerate R&D efforts as voice AI technology reaches an inflection point for widespread enterprise adoption.
