Synthflow set out to make enterprise-grade voice AI accessible to any business, not just those with large machine-learning teams. Founded in 2023 by brothers Albert and Hakob Astabatsyan together with Sassun Mirzakhan-Saky, the company began by experimenting with OpenAI's APIs and evolved into a full no-code platform for designing, testing, and deploying conversational voice agents. The product lets operations and customer-experience teams build agents through a visual interface, connect them to telephony and business systems, and put them on the front line of phone-based customer interactions.
The core promise is voice that feels human. Synthflow combines low-latency speech pipelines, interruption handling, and natural turn-taking so callers can speak as they normally would. Agents can answer inbound calls, place outbound calls, qualify leads, book appointments, and escalate to human staff when needed. The company reports that its agents have processed over 45 million calls, saved more than five million contact-center hours, and answered roughly 35% more calls than non-AI operations during peak demand.
Synthflow is positioned for contact centers and business process outsourcing (BPO) providers, where call volume is high and staffing is expensive. Because the platform is no-code, non-technical teams can iterate on call flows, prompts, and integrations quickly, while developers can extend behavior through APIs and webhooks. Enterprise concerns such as uptime, observability, and multi-language support are central to the pitch.
In June 2025, Synthflow raised a $20 million Series A led by Accel, with participation from existing investors Atlantic Labs and Singular, bringing total funding to around $30 million since launch. The capital is earmarked for global expansion, including a new US office, and continued investment in the underlying voice models and agent platform. The round placed Synthflow among the more closely watched European entrants in a crowded voice-AI category.
