Synthflow AI raises $20M to transform the global conversational AI market

Germany-based Synthflow AI, the voice AI platform for automated phone calls, has closed a $20 million Series A investment round to drive the next wave of enterprise adoption for AI voice agents. This follows the company’s seed round last year, bringing the total funding to $30 million. 

Founded in 2023, Synthflow AI democratises 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.

Designed for non-technical users, Synthflow AI’s white-label voice agents require zero code, are highly customisable, 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 over 200 integrations across calendars, CRMs and telephony systems, Synthflow AI can 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, offering the best-in-class quality, low latency, and high reliability. It can handle complex, high-value use cases with no human intervention. Synthflow AI agents have already delivered a measurable impact.

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 round is led by Accel, with participation from existing investors Atlantic Labs and Singular.

Luca Bocchio, Partner at Accel, believes voice AI has reached a true inflexion point, with voice agents now advancing rapidly and more affordable than ever to deploy. He comments: 

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 grown its R&D team to enhance product performance and quickly scaled to serve BPO providers and contact centres globally. 

The new funding will fuel international expansion, including a new US office, and accelerate development of its advanced voice AI agent platform.
