Inside Synthflow: Revolutionizing Customer Calls with Human-Like Voice AI

Leading Voice AI Innovation

Hakob Astabatsyan, Co-Founder and CEO of Synthflow, is pioneering advanced voice AI technology designed to automate customer calls with natural, human-like responsiveness. Founded in Berlin in 2023, Synthflow aims to make conversational AI accessible to businesses of all sizes.

Rapid Growth and Industry Impact

Under Hakob's leadership, Synthflow has quickly expanded across Germany and the U.S., supporting industries such as real estate, healthcare, and finance. The platform enables companies to deploy no-code custom voice agents within weeks, handling both inbound and outbound calls. These agents integrate seamlessly with over 200 applications and CRMs, delivering cost-effective, highly accurate customer interactions.

Democratizing Voice AI for Businesses

Hakob’s vision is to remove technical and financial barriers, allowing startups and mid-sized companies to utilize voice AI without extensive engineering resources. Synthflow’s no-code platform empowers teams in sales, support, and operations to design and launch voice agents through an intuitive browser interface, transforming AI from a back-office tool into a frontline business asset.

Building Voice Agents Made Simple

Synthflow’s drag-and-drop interface enables users to craft complete call flows, including greetings, follow-ups, tone settings, and fallback behaviors. Integration with existing systems like CRMs and calendars is straightforward. The platform handles all backend processes such as transcription, speech synthesis, and large language model (LLM) inferences, enabling clients to go live in under two weeks.

Technical Breakthroughs for Performance

Achieving sub-500ms latency and near-perfect uptime involved innovations like edge computing, real-time streaming, and model-level optimization. The architecture supports parallel processing and incorporates redundancy, failover routing, and distributed cloud infrastructure. Currently, Synthflow processes over 40 million calls each month.

Ensuring Accuracy and Brand Safety

Synthflow’s voice agents focus on specific, goal-driven tasks, minimizing AI hallucinations by ignoring unrelated prompts. A built-in knowledge base allows precise control over what the agent can and cannot address, ensuring brand-safe and accurate conversations.

Building Trust Through Natural Interaction

Trust is earned by delivering fast, relevant, and naturally sounding responses, with human conversational cues such as pauses and filler words. Synthflow avoids overextending AI capabilities by focusing agents on defined tasks and escalating complex cases to human agents.

Security and Compliance Prioritized

Synthflow meets stringent security standards including SOC 2, GDPR, and HIPAA compliance. Data encryption, role-based access, audit logs, and consent frameworks are integrated to protect sensitive information.

Human-AI Collaboration

AI handles routine calls, freeing human agents to tackle complex and emotional conversations. The AI collects context and intent before seamlessly passing calls to humans, enhancing customer experience through effective collaboration.

European Influence on Growth Strategy

Based in Berlin, Synthflow benefits from a tech ecosystem that emphasizes privacy, ethical AI, and regulatory compliance. This focus strengthens the platform’s trustworthiness and readiness for evolving global AI regulations.

Future Trends in Voice AI

Hakob predicts that AI will power over half of B2B voice interactions soon, with AI-to-AI conversations managing workflows. He highlights the rise of no-code and low-code AI orchestration as an underappreciated trend, enabling businesses to deploy AI solutions without coding.
