For Impact AI Montreal 2026, Vooban created an immersive and seamless experience, reflecting its leadership in artificial intelligence.
For Impact AI Montreal 2026, Vooban aimed to provide an immersive experience befitting its position in artificial intelligence. The challenge was to transform the venue into a cohesive, fluid, and distinctive environment, where each area, from the main stage to the content, networking, catering, and broadcast spaces, contributed to a seamless participant experience.
Altitude/C supported Vooban every step of the way, from space design to logistical, technical, and vendor coordination. By adapting the layout plans to the site's realities and incorporating strong experiential elements, such as the immersive tunnel and a prominently featured stage, the team created an engaging journey conducive to exchanges, learning, and content creation.

Divergences: an inaugural edition designed to bring together curious minds, foster exchange, and create lasting connections within the business ecosystem.
Launching a brand new event was a significant challenge. With no history, no established audience, and no previous editions to build upon, we had to design the Divergences experience from scratch while ensuring its financial viability. Engaging partners, selling sponsorships and tickets, and creating relevant programming required a constant balance between ambition, appeal, and operational realities. The success of this first edition also relied on rigorous coordination among all stakeholders to deliver a cohesive and professional experience right from its debut.
Altitude/C supported Latitude through every stage of the project, handling the planning, coordination, and execution of the event. The team orchestrated various logistical aspects, from participant reception to vendor management, from the networking cocktail to the exhibitor space, and also coordinated speakers and partners. Thanks to a strategic approach focused on user experience and value creation for all stakeholders, Divergences quickly established itself as a credible and promising initiative. The quality of execution, the relevance of the participant journey, and the abundance of networking opportunities laid a solid foundation for the event's growth and sustainability.

Three cities, one energy: an immersive experience to unveil Securian Canada's new brand identity.
To mark the launch of its new brand identity, Securian Canada wanted to engage its employees through a unifying experience rolled out simultaneously in Montreal, Toronto, and Burnaby. The challenge was to provide a consistent experience from coast to coast, while taking into account the specific realities of each site and fostering team buy-in for this important organizational transformation. The situation became even more complicated when the Montreal event had to be postponed less than 24 hours before its original scheduled date.
Altitude/C supported Securian Canada in the planning and execution of this national initiative by coordinating all operations, suppliers, and partners across the three cities. The team also designed immersive multimedia content to bring the new brand to life and create a memorable experience for participants. Thanks to the rapid implementation of a contingency plan and the integration of learnings from other sites, the re-launched event in Montreal benefited from an optimized experience, true to the brand's vision and aligned with the organization's engagement objectives.

The 2026 Montreal Climate Summit: when the diversity of voices is transformed into a collective commitment to the climate.

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.
