OPUS Marketing

What OPUS Marketing does

OPUS Marketing GmbH is a Vienna-based, privately held full-service event agency (Austrian GmbH) founded in 1994, operating with approximately 12 full-time employees. The company plans, organizes, and executes corporate events end-to-end across three formats — virtual, hybrid, and live — serving B2B clients including corporations, medical/scientific associations, and exhibition organizers. Documented marquee engagements include a virtual supplier webcast for BRP-Rotax, the OBO Bettermann Sommerfest 2023 (up to 500 guests), the inaugural PEMA 2024 personal manager Expofestival (1,000+ attendees), the annual LOG ophthalmology conference, and the 46th Annual Meeting of the Austrian Society for Trauma Surgery (ÖGU).

The company differentiates through proprietary in-house production assets: the OPUS Streaming Studio (mobile, broadcast-quality, multi-country bi-directional streaming), a custom event portal with registration, participant tracking, and ROI reporting built on in-house 2D/3D graphics, and Mila-wall® modular wall systems (soundproofed, high-stability, described as unique in Austria) used for room-in-room concepts in museums and exhibitions. It also holds the Austrian Environmental Seal for Green Meetings, CEA certification, and the Managing Director's CEM (ISO/IEC TÜV 17024) credential, alongside memberships in EMBA, MPI, ILEA Europe, and the Austria/Vienna Convention Bureaus.

The business model is professional services on a project-based, custom-quoted basis, with no public pricing tiers and no disclosed long-tail standardized contracts. Revenue is generated through one-off enterprise events (conferences, congresses, employee and customer events, summits, trade-show booths, hybrid and green meetings), supported by technology partnerships with Google Cloud (EU), A1 Telekom Austria, Mittwald, Sendinblue, and a German video-stream host, plus the Mila-wall GmbH partnership for modular walls. The firm is founder/owner-operated by Managing Director Erik R. Kastner, MBA, with no disclosed institutional investors, parent company, or subsidiaries.

• insglück Gesellschaft für Eventkommunikation: Berlin-based mid-sized creative event agency specializing in corporate events, conferences, and hybrid formats. Closely comparable in size, service portfolio, and enterprise B2B positioning to OPUS, with similar full-service event production capabilities.

Regional players

• Messe Wien (Reed Messe Wien): Vienna-based trade fair and congress venue and organizer that hosts major Austrian exhibitions and conferences. Direct domestic competitor to OPUS for the same pool of Austrian corporate event budgets, particularly for large-scale congresses and trade shows.
• m:con - mannheim:congress GmbH: German congress and event organizer operating the Congress Center Rosengarten Mannheim. Comparable in congress and conference management services with a DACH regional focus, similar to OPUS's Austrian specialty.

Broad incumbents

• MCH Group: Swiss-based marketing platform operating behind major art and trade fairs (Art Basel, Swissbau) and congress venues. Overlaps with OPUS in large-scale congress and exhibition organization, with a comparable DACH regional footprint.
• GL Events: French-listed integrated event services group operating venue management, event production, and exhibition services worldwide. Comparable in offering end-to-end event solutions including proprietary equipment and technology, though at a substantially larger scale than OPUS.
• MCI Group: Global meetings, events, and association management company headquartered in Switzerland. Significantly larger than OPUS but offers the same full-service conference, congress, and corporate event execution, making it a clear structural comparable in the broader MICE category.

Emerging players

• Bizzabo: Global event experience platform providing event management software for in-person, hybrid, and virtual events. Overlaps with OPUS's custom event portal technology but competes as a software-only alternative rather than full-service producer.
• Eventbrite: Global event technology platform for ticketing, registration, and event marketing. Operates adjacent to OPUS's event registration and participant tracking capabilities, representing a software-driven alternative for portions of the event workflow.
