At the core of the platform is its AI Voice Operating System, designed to sound human, respond with low latency, and deliver reliable performance. Synthflow AI is already proving its value by handling complex, high-impact workflows with no human involvement.

Hakob Astabatsyan, co-founder and CEO of Synthflow AI, explained: 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 centre 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.

The funding round was led by Accel, with continued support from existing investors Atlantic Labs and Singular.

Luca Bocchio, Partner at Accel, said that voice AI is at a real turning point, with voice agents becoming more advanced and easier to deploy at lower costs than ever before.

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.

Since its 2024 seed round, Synthflow AI has expanded its R&D team to improve product performance and quickly scaled to support BPO providers and contact centres worldwide.

The new funding will support the company’s global expansion, including opening a new office in the US, and will speed up the development of its advanced voice AI platform.
