Hrenko Digital Agency

Founded in 2009, Hrenko Digital Agency is a senior web development and digital product team delivering fast, scalable and long-lasting digital solutions. Our main technology pillar is Synergy Fox, our API-driven, modular and high-performance CMS. It is designed to be easily extensible, secure, extremely fast and capable of serving very high traffic — making it ideal for complex portals and demanding digital ecosystems.

We are one of Hungary’s leading agencies in tourism and destination web development, with large-scale references such as the Széchenyi Thermal Bath, one of the world’s most iconic spa brands, and Visit Eger, one of Hungary’s highest-traffic tourism destinations. Our work supports millions of sessions annually across multiple platforms.

We provide true end-to-end development, covering specification, UX/UI design, sprint-based agile development and long-term operational support. Our clients value us for our reliability, direct communication, transparency and strategic mindset — many partnerships have lasted well over a decade.

In recent years we have shifted our entire development approach toward preparing brands for the AI-search era. All new websites are fully LLM-compatible, built with clean information architecture, structured content systems and GEO (Generative Engine Optimization) principles that increase visibility in AI assistants such as ChatGPT, Gemini and Perplexity.

Beyond traditional web development, we also deliver AI-enhanced solutions, including RAG-based knowledge systems, custom automation workflows, and integrations built on n8n or bespoke microservices. These help clients streamline operations, enrich customer experiences and modernize their digital infrastructure.

Our mission is to transform business goals into future-proof digital products — with an honest, long-term and partnership-driven mindset.
