In a context of strong growth and increased reputation, the main challenge of the 2025 edition of Xplor was to make the event evolve without losing the coherence or the quality of the experience. Altitude/C needed to support the organization in the complete renewal of the environment and participant paths, while ensuring smooth logistical management at the scale of a large-scale event. The challenge was to integrate new reception tools, to rethink services and to coordinate all stakeholders in order to offer a modern, efficient experience that met the expectations of an expanding community.
Altitude/C has deployed a global approach focused on transforming the participant experience. The team redesigned the event environment through a completely renewed decor and improved signage, while optimizing the routes thanks to the implementation of a new registration platform and a more efficient roundabout system. The close coordination of hotel services, partners, exhibition, and content teams ensured a smooth and consistent experience at every stage of the event, in line with Xplor's ambitions for growth and innovation.

Have questions about what a PCO actually does and how we work? You're in the right place. We've answered the most common ones here to help you get clarity before we even have our first conversation.
Contact UsA professional congress organizer (PCO) specializes in the strategic planning and complete management of large-scale congresses: scientific, medical, professional, or governmental. Unlike an event agency that handles the production of corporate events, a PCO works directly with associations and professional societies to achieve their strategic objectives while reducing the workload on their internal teams.
An event agency designs and produces experiences: launches, galas, corporate events. A PCO goes much further. It takes charge of the entire lifecycle of a congress, from initial strategy to managing registrations, abstracts, sponsorships, accommodations, and on-site operations. It is an end-to-end management partner, not just a production vendor.
As early as possible, ideally 12 to 18 months before the congress takes place. This window allows you to secure the best venues and destinations, structure the program in advance, and maximize sponsorship and registration revenue. Reaching out to a PCO late often means playing catch-up. Reaching out early means building your congress on solid ground.
