Synthflow AI is a Berlin-based no-code platform enabling enterprises to build and deploy customized white-labeled voice AI customer service agents. The company launched in 2023 and emphasizes enterprise-grade deployments with HIPAA and GDPR compliance and more than 200 integrations including Salesforce, Twilio, and HubSpot. Synthflow has amassed over 1,000 customers, handled more than 45 million calls to date, and now processes roughly 5 million calls monthly. The startup grew 15x last year and reports over 90% retention among enterprise customers. Leadership describes the business as being in a post-product-market-fit era with a clear product roadmap focused on depth of technology and enterprise integrations. The company plans to use funding to expand its team, boost research and development, and open its first U.S. office. Synthflow provides a browser-based no-code tool that lets SMEs design AI voice agents to handle inbound calls, schedule appointments, run FAQs, and extract customer information. The product layers a drag-and-drop interface on top of LLMs (building on OpenAI’s GPT and its own fine-tuned models) along with a custom voice orchestration layer that converts speech-to-text and back to synthesized speech. Since launching from stealth in December 2023 the company reports approaching 1,000 customers and “double-digit” monthly growth. The startup has added German and French language versions in beta and is focused on integrations with third-party software and CRM/calendar workflows. Future R&D priorities include expanding language/market focus, enabling live actions (e.g., inventory checks) during calls, and broadening the range of SMEs served. The founding team includes CEO and co-founder Hakob Astabatsyan, his brother Albert, and CTO Sassun Mirzakhan-Saky.
