Synthflow AI, a pioneering voice AI platform specializing in automated phone calls, has successfully closed a $20 million Series A investment round. This significant funding initiative is set to accelerate the widespread enterprise adoption of AI voice agents. The round was spearheaded by Accel, a prominent global venture capital firm, with additional participation from existing investors Atlantic Labs and Singular. Following a previous seed round, this latest investment brings Synthflow AI’s total funding to $30 million. The newly secured capital will be strategically utilized to fuel global expansion efforts, including the establishment of a new office in the United States, and to expedite the ongoing development of its state-of-the-art voice AI agent platform.

After a period of relatively slow advancement, voice AI technology is currently at a critical inflection point. Recent breakthroughs have made it practically viable for enterprises to deploy AI voice agents at scale across an extensive array of applications. These advanced agents are capable of transforming global operations by providing exceptional support at a fraction of conventional costs, handling tasks from customer service inquiries and appointment scheduling to lead qualification. This technological shift represents a substantial growth opportunity, particularly for contact centers and Business Process Outsourcing (BPO) companies that collectively command the $159 billion US customer service market. The demand for always-on voice agents capable of natural conversations is a key driver in this sector.

Historically, deploying sophisticated voice AI while maintaining a competitive edge in an increasingly crowded market has posed considerable challenges, often demanding specialized AI expertise, dedicated teams, inflated budgets, and prolonged onboarding processes. Founded in 2023 by serial entrepreneurs Albert Astabatsyan, Hakob Astabatsyan, and Sassun Mirzakhan-Saky, Synthflow AI addresses these barriers by democratizing access to advanced voice AI through its intuitive no-code platform. This innovative platform empowers enterprises to effortlessly create, deploy, and scale natural-sounding, cost-effective voice agents meticulously tailored to their specific business requirements. Designed with non-technical users in mind, Synthflow AI’s white-label voice agents necessitate zero coding, offer extensive customization, and are equipped to manage a diverse range of interactions, from simple inquiries to complex workflows. These include comprehensive customer support, precise appointment scheduling, efficient inbound lead qualification, seamless AI-to-human call transfers, and the real-time collection and dissemination of information at scale.

With over 200 integrations spanning various calendars, Customer Relationship Management (CRM) systems, and telephony platforms, Synthflow AI can be implemented rapidly and cost-effectively. This stands in stark contrast to the typical six-month onboarding periods often required by legacy vendors in the industry. The company's pioneering AI Voice Operating System (OS) is engineered to be virtually indistinguishable from a human voice, ensuring best-in-class quality, minimal latency, and exceptional reliability. This robust system is capable of autonomously handling complex, high-value use cases without human intervention.

Since its seed funding round in 2024, Synthflow AI has significantly expanded its Research and Development team to further enhance product performance. It has also rapidly scaled its operations to integrate with BPO providers and contact centers worldwide. The measurable impact delivered by Synthflow AI agents is substantial, including saving over 5 million hours of contact center operations, achieving 35% more calls answered compared to non-AI operators, and handling 45 million calls with an impressive 99.9% uptime.

Hakob Astabatsyan, co-founder and CEO of Synthflow AI, emphasized the growing comfort businesses and their customers have with AI agents. He stated, “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, also commented on the investment, noting, “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.” Synthflow AI stands as a G2 Grid Leader for AI Agents and is trusted by over 1,000 customers, with its growth reflecting a broader industry trend toward sophisticated and accessible conversational AI in a global market projected to reach $168.2 billion.
