How Synthflow AI Is Redefining Enterprise Voice AI

The market for conversational AI has experienced explosive growth since the launch of ChatGPT in November 2022. Experts predict it could reach nearly $50 billion globally by 2031. Synthflow AI, a Berlin-based startup, is forging its path in this crowded sector by offering enterprise-ready, no-code solutions for voice-powered customer service agents.

Synthflow AI: Focused on Enterprise Needs

Synthflow AI distinguishes itself by making advanced voice AI accessible and compliant for enterprises without requiring development expertise. Their no-code platform enables organizations to create and deploy customizable, white-labeled voice assistants that can integrate with over 200 business tools—including Salesforce, Twilio, and HubSpot.

Launched in 2023, Synthflow AI has already attracted more than 1,000 clients and successfully powered over 45 million customer calls. Its platform is compliant with HIPAA and GDPR, meeting strict enterprise demands for privacy and data security.

The Journey from Idea to Enterprise Platform

Co-founders Hakob Astabatsyan (CEO), Albert Astabatsyan (CPO), and Sassun Mirzakhan-Saky (CTO) began experimenting with OpenAI’s API in early 2023. Initially building text-based bots, they soon saw the potential and technical complexity of real-time voice AI. Achieving the responsiveness and natural feel required—like sub-400ms latency and seamless handling of interruptions—proved a formidable challenge.

Undeterred, the founders devoted their efforts solely to voice AI. Synthflow’s beta launched in early 2024, followed by an enterprise-grade product by year-end. Their user base grew rapidly (over 15x in 2024) and retained more than 90% of enterprise customers, signaling strong product-market fit.

Growth and Investment

Synthflow AI now handles about 5 million calls per month, a significant leap from its previous volume and a sign of the rising appetite for voice automation. Recently, the company secured a $20 million Series A investment led by Accel, with Atlantic Labs and Singular also participating. According to CEO Hakob Astabatsyan, the funding will fuel team expansion, R&D, and Synthflow’s entry into the U.S. market.

The investment validates both Synthflow’s vision and the broader market trend toward smarter, integrated enterprise solutions. As Accel partner Luca Bocchio noted, the founding team's commitment to robust integrations and compliance helped differentiate Synthflow from other contenders.

The Competitive Landscape & What Lies Ahead

The conversational AI market includes well-funded players like Sierra (which has raised $285 million) and Bland AI (over $50 million raised), among others. While innovation moves quickly, Synthflow’s leadership sees a clear path: their target customer is defined, their product vision is focused, and they believe the company is positioned for long-term impact.

Why it matters

The enterprise shift toward no-code AI tools, particularly for customer-facing voice automation, signals a democratization of advanced technology. This increases the potential for smaller organizations to level the playing field with larger competitors. For founders and product builders, it marks a maturation in how AI is delivered—not just as raw capability, but as user-friendly, integrated business infrastructure.

Risks & opportunities

The lightning pace of AI means today’s solutions can become outdated quickly, while high compliance standards and integration requirements create barriers for new entrants. However, startups that successfully combine low-code/no-code accessibility with deep integrations and privacy will continue to see strong adoption. Looking back at the success of early SaaS and CRM players, the most versatile and open platforms will carve out major market share.

Startup idea or application

Inspired founders might target the next wave of industry-specific voice bots—think HIPAA-compliant voice assistants tailored for healthcare clinics, or multilingual call center agents with compliance features for cross-border telecom. Another opportunity is a plugin ecosystem that allows businesses to add custom modules (emotion detection, real-time translation) to their existing AI voice agents—creating a marketplace model on top of platforms like Synthflow.
