MCI Group Holding

What MCI Group Holding does

MCI Group Holding SA is an independent global marketing communications collective founded in 1987 and headquartered in Geneva, Switzerland. The group delivers strategy, creativity, and execution across six integrated capabilities: engagement and events, strategic communications and public affairs, social media and branded content, creative technology and production, data and research, and community and association management. It serves a diversified mix of global enterprise brands (Adobe, IBM, Moët & Chandon, Nissan, Pret A Manger), governments and EU institutions (French National Olympic Committee, Paris Peace Forum, European Space Conference), associations and federations, and NGOs across 34 countries.

The group operates a multi-brand agency platform — Black Flower (luxury), Dorier (audiovisual), ESN (EU institutions), HAGEN INVENT (live communication), Insidery (consulting), Logos (public affairs), MCI Agency (engagement marketing), Ovation Global DMC (destination management), EYXO (content), Tipik (European communications), Matter (social), and Demodern (creative technology) — unified under shared services including SAP SuccessFactors HR, Microsoft 365 Copilot, the proprietary SwitchAI learning platform, markus audience tool, and the D.I.V.E.© and F.A.S.T.© consulting frameworks. Technology is positioned under an 'Authentic Intelligence' philosophy that combines AI with human creativity and judgment.

Revenue is generated primarily through project-based professional services fees for designing and delivering brand experiences, events, congresses, digital activations, and association management across live, hybrid, and virtual formats, supplemented by recurring framework contracts in EU public affairs (notably via ESN). Disclosed turnover was €581.7M in 2025 across 5,300 campaigns for 1,220 clients, up from €241M in 2021 (a post-COVID recovery followed by mid-single-digit organic growth), with 2,066 employees in 64 offices. Distribution is via direct enterprise field sales, the multi-brand agency network, and flagship project demonstrations as marketing showcases. The group has no public-market listing and remains founder/management-controlled under CEO Sebastien Tondeur.
