OUR STORY

A market on the verge of becoming structured.

The global MICE market is estimated at $946 billion in 2025, more than half of it in Europe. Yet the vast majority of companies still have no structured program or tool to manage and optimize this spend.

For years, MICE operated in the blind spot of procurement departments. Scattered spend, informal processes, providers chosen on trust rather than performance. OneMICE fills that gap by bringing the standard, the common language, and the legitimate framework the market had been waiting for.

"The MICE market has become more aware of its strategic importance. But it lacked a standard, a common language, a legitimate framework recognized by all its players. That is exactly the gap we are filling."
— Jean de Villeneuve Bargemont, CEO and co-founder

THE FOUNDERS

Three paths, one mission.

OneMICE was born from the meeting of two entrepreneurial families who have shaped the European MICE market for 50 years, combined with international transformation expertise.

Jean de Villeneuve Bargemont CEO and Co-founder

15 years of international intrapreneurship (China, Europe, USA), member of Châteauform's executive committee (COMEX) and CEO of CERAN. He bridges the two families and drives the strategic vision of the project.

Vinzenz Graf von Brühl Co-founder

Second generation of MICE Portal, the reference German platform for 20 years. He brings the technical depth, product expertise, and European vision needed to structure the market.

Benjamin Abittan Co-founder

Second generation of Châteauform', the European leader in corporate seminars (80+ venues, 2,200 employees). He brings the European network, on-the-ground presence, and deep knowledge of corporate MICE challenges.

THE SOLUTION

At the heart of the European MICE ecosystem.

OneMICE serves three players in the MICE ecosystem at once. A single infrastructure for companies, providers, and intermediaries.

01 For companies

A complete source-to-pay governance platform to centralize, track, approve, and optimize MICE spend. Dedicated tenants for major-account clients, auditable compliance, ERP, finance, and travel integrations. Average observed savings of 22%.

02 For MICE providers

The MICE Partner Network (MPN) is the reference network for event procurement profiles. Contact us to be listed with the full pool of corporate buyers and agencies. Our commission model is ethical: no commission if a framework agreement already exists.

03 For intermediaries

Consultants and agencies can structure their MICE management through a dedicated agency shop (specific process, clients, and commissions, while accessing the entire MPN). If a client deploys its own OneMICE platform, the intermediary keeps serving them through the platform.

STRATEGIC PARTNERS

80+ Châteauform' venues join the MICE Partner Network.

The partnership with Châteauform' group marks the official launch of the MPN with unmatched depth of offering from day one. IME, a leading event broker on the French market for 20 years, also becomes OneMICE's first French intermediary partner.

"The collaboration model offered by OneMICE and its MICE Partner Network is what committed MICE players have been waiting for. Châteauform' is delighted to be one of the first partners."
— Delphine Bouclon, Director of Development and Commercial Strategy, Châteauform'

France, OneMICE's first market.

With its strong events culture, density of profiles, and growing maturity in indirect procurement, France is the ideal territory to set this first European milestone.
