CSi Hamburg GmbH

What CSi Hamburg GmbH does

CSi Hamburg GmbH is a Hamburg-based, privately held professional services firm founded in 2013 that organizes, consults on, and executes scientific conferences, symposia, and corporate incentive events, primarily for scientific societies, academic associations, and institutions in the German-speaking market. Its core offerings span full-service conference management (Konferenzen), interdisciplinary symposia with e-solutions for abstract submission, peer review, proceedings publication, and poster/industrial exhibition coordination (Symposien), team-building and incentive programs, and add-on modules including membership and secretariat administration, speaker and chairperson management, and event website design with corporate identity. Since April 2020 the firm has expanded into Online-Meetings und Konferenzen, providing technical setup, support, and digital care for online and hybrid events delivered in partnership with experienced IT service providers for multi-day congresses with parallel program strands.

The underlying technology is a modest web-based event management platform built on standard web technologies (SSL encryption, JavaScript, cookies) supporting marketing, registration, and event website functionality, with no disclosed proprietary AI, data, or platform IP. The firm runs on a quote-based, custom pricing model with no publicly disclosed rates or contract structures, and goes to market primarily through its company website, email newsletters, Google Analytics, and Google AdWords. Distribution is regional and direct-to-client via consultative B2B engagement.

The business model is a bootstrapped, owner-led boutique: Antje Blömeke serves as Geschäftsführerin (Managing Director), the team comprises approximately 5 employees, there are no disclosed funding rounds, subsidiaries, M&A, or parent company, and the firm is GDPR-compliant (DSGVO) in its handling of participant and member data. The implied economics are professional services billings on a project basis, with retained mandates from scientific societies providing recurring revenue visibility.

Direct peers

• Congrex Switzerland: Swiss association and conference management company serving scientific and professional societies across Europe with PCO, secretariat, and event delivery services — a direct competitor in the European scientific PCO niche.
• Kenes Group: Global PCO and association management firm with deep scientific/medical society expertise, offering congress organization, secretariat, and association management — directly comparable to CSi Hamburg at a larger scale.
• Interplan Congress, Meeting & Event Management AG: German-headquartered PCO with a strong scientific and medical association practice, offering full-service conference organization including abstract handling, proceedings, and on-site management — directly comparable to CSi Hamburg's core offering.
• K.I.T. Group GmbH: Berlin-based association management and PCO firm specializing in scientific and medical society conferences, including abstract management, secretariat services, and event delivery — directly overlapping CSi Hamburg's niche and service mix.
• Conventus Congressmanagement & Marketing GmbH: Jena-based PCO specializing in scientific and medical conferences for German-speaking associations and societies, with end-to-end conference and abstract management services that closely mirror CSi Hamburg's positioning.

Broad incumbents

• BCD Meetings & Events: Global meetings and events agency serving corporate and association clients with full event lifecycle services — a broader incumbent whose association and corporate incentive work overlaps with CSi Hamburg's portfolio.
• MCI Group: Large global events and association management group covering meetings, incentives, congresses, and association services across many verticals — a much broader incumbent that competes with CSi Hamburg for scientific society work.

Emerging players

• EuroSciCon: Independent scientific conference organizer running events across biomedical and life-science disciplines — an emerging player with thematic overlap to CSi Hamburg's scientific society work.
• Cvent: Event-management technology platform offering registration, abstract management, attendee engagement, and virtual event tools — an emerging tech-driven competitor that could enable scientific societies to bring PCO functions in-house, eroding boutique PCO scope.

Regional players

• Seminaris HotelGroup / Lindner Hotels (corporate incentive venue operators): DACH-region hotel and meeting venue operators offering incentive and team-event packages — adjacent rather than directly competing, but overlapping with CSi Hamburg's incentive event line.
