Synthflow AI, a voice AI platform for automated phone calls, announced a $20 million Series A investment round to drive the next wave of enterprise adoption for AI voice agents. The funding round was led by Accel, with participation from existing investors Atlantic Labs and Singular.
This follows the company’s seed round last year, bringing the total funding to $30 million.
How the funding will be used: The new funding will support global expansion, including the opening of a new office in the US, and accelerate development of its best-in-class voice AI agent platform.
Problem being addressed: Following decades of slow progress, voice AI technology is at a turning point. And recent breakthroughs have made it viable for enterprises to deploy AI voice agents at scale across a wide range of use cases. From customer service to appointment scheduling and lead qualification, these agents transform global operations, delivering support at a fraction of the cost. For contact centers and business process outsourcing (BPO) companies that dominate the massive US customer service market, this shift presents a major growth opportunity, driven by always-on voice agents delivering natural conversations. Until now, deploying this technology while standing out in a crowded space has been a challenge, demanding deep AI expertise, specialized teams, inflated budgets, and drawn-out onboarding.
Built for non-technical users, Synthflow AI’s white-label voice agents require zero code, are highly customizable, and can handle everything from simple inquiries to complex workflows, including customer support, appointment scheduling, inbound lead qualification, AI-to-human call transfers, and collecting and sharing real-time information at scale. With 200+ integrations across calendars, CRMs, and telephony systems, Synthflow AI could be implemented rapidly and cost-effectively, a contrast to the typical six-month onboarding required by legacy vendors.
Synthflow AI’s pioneering AI Voice Operating System (OS) is built to be indistinguishable from a human voice, providing the quality, low latency, and high reliability. And it can handle complex, high-value use cases with no human intervention. Since its seed round last year, Synthflow AI has expanded its R&D team to boost product performance further and has rapidly scaled to integrate with BPO providers and contact centers worldwide.
Company founders: Launched in 2023 by serial entrepreneurs Albert Astabatsyan, Hakob Astabatsyan, and Sassun Mirzakhan-Saky, Synthflow AI democratizes access to advanced voice AI with a no-code platform that lets enterprises easily create, deploy, and scale natural-sounding, cost-effective voice agents tailored to their business needs.
Momentum: Synthflow AI agents have already delivered a measurable impact:
— Over 5 million hours of contact center operations saved
— 35% more calls answered compared to non-AI operators
— 45 million calls handled with a 99.9% uptime
