Voice agents specialist Synthflow AI bags $20m in Series A funding round headed up by Accel

Synthflow AI, a voice AI platform for automated phone calls, has announced a $20 million Series A investment round 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. The new capital will support global expansion, including the opening of a new office in the US, and accelerate development of its voice AI agent platform.

Founded in 2023 by serial entrepreneurs Albert Astabatsyan, Hakob Astabatsyan, and Sassun Mirzakhan-Saky, Synthflow AI aims to democratise access to advanced voice AI with a no-code platform that, according to those involved, lets enterprises create, deploy and scale natural sounding, cost-effective voice agents tailored to their business needs.

Designed for non-technical users, Synthflow AI’s white label voice agents 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.

Hakob Astabatsyan, Co-founder and CEO at Synthflow AI, says: “Businesses and their customers are becoming increasingly comfortable communicating with AI agents. Our mission at Synthflow AI is to make high quality, low cost AI voice agents more accessible to improve customer services everywhere.”

“The BPO and contact center market represents a massive opportunity for us, and we're already experiencing significant growth in this sector thanks to the simplicity of our no-code platform and the reliability and quality of our AI voice agents. This funding will help us accelerate this growth and scale our product so that we can continue pioneering Voice AI technology globally.”

Luca Bocchio, Partner at Accel, says: “Voice AI is at a real inflection point, voice agents have been improving rapidly and have never been more cost effective to deploy. The Synthflow AI team is seizing the moment from legacy players by making this technology more accessible.”

“The market opportunity for deploying voice agents in traditional customer support use cases is vast and, as infrastructure continues to evolve and AI capabilities improve further, new emerging use cases in areas such as healthcare, financial services, education and more will continue to open up. Hakob and the team’s technical expertise and momentum so far have been impressive. We’re delighted to be investing in their vision and joining the journey ahead.”
