Diamond Congress

What Diamond Congress does

Diamond Congress Kft. is a privately held Hungarian Professional Conference Organizer (PCO) founded in 1994 by Attila Varga and headquartered in Budapest. The company provides end-to-end conference and exhibition organization services to scientific societies, academic institutions, professional associations, and medical organizations across Hungary and select European markets. Over 30 years, it has organized more than 300 documented conferences ranging from small workshops to congresses with hundreds to over a thousand participants, with reference clients including the Federation of European Biochemical Societies (FEBS), the Hungarian Biochemical Society, the Hungarian Society of Physiology, Semmelweis University, the International Association of Hydrogeologists, and the Hungarian Association of Pediatricians.

The company's service stack is anchored by two proprietary technology platforms and a mobile application. e-Vent Space, launched in 2020, is a self-developed online event platform enabling virtual and hybrid conferences, exhibitions, webinars, and courses with real-time participant interaction and virtual exhibition capabilities. The Diamond Professional Congress System (DPCS) handles online registration, abstract submission, and payment processing through integrated payment gateways (SIX Payment Services and OTP Bank) with SSL-secured transactions and GDPR-compliant data handling. A small multilingual team of approximately 5 named key personnel delivers the operations.

Diamond Congress operates a relationship-driven B2B sales model, acquiring clients through direct outreach, RFP responses, industry referrals, and its long-standing reference portfolio. Revenue is generated across four streams: participant registration fees (transaction-based), exhibition and sponsorship services (professional services), virtual event services (recurring/subscription), and ancillary conference services such as hotel bookings, transfers, abstract book production, and proceedings publishing. The company is a member of EFAPCO (European Federation of Professional Conference Organizers) and MaReSz (Hungarian Association of Event Organizers), providing industry credibility and access to European PCO networks.
