Snowflake at Cannes Lions 2025

Snow is coming to Cannes, France! Snowflake is back again at the Cannes Lions International Festival of Creativity on June 16-20, 2025. As the premiere media and entertainment industry event of the year, Cannes brings together creative legends, marketing luminaries and cutting-edge content creators from around the world to shine a light on the latest trends and bring to the forefront ideas and critical topics shaping the future of the industry. 

We are beyond excited to be back at Cannes this year, sharing how the Snowflake AI Data Cloud for Media, a leading data and AI platform, and our partners are delivering a multitude of competitive advantages and ROI for advertising, media and entertainment companies. We are also looking forward to candid conversations with our customers and partners about how AI is transforming the industry and the continued critical role data clean rooms have in helping customers ensure consumer privacy and deliver secure data collaboration and analysis.

See our list of not-to-miss events below. Or book a meeting with us now.

Snowflake Data Clean Rooms are vital for secure multipartner data collaboration, especially in the advertising industry. However, fragmented ad measurement, particularly with streaming media, poses challenges for tracking and attribution. To address this, Snowflake is innovating within its Data Clean Rooms to create a unified, privacy-aware environment for advertising measurement. This orchestration connects media publishers, advertisers and measurement partners in a neutral space for secure data sharing and custom measurements, eliminating rigid solutions and enabling flexible management of ad logs and real-time insights for precise campaign optimization.

Snowflake’s developments in Data Clean Rooms further streamline and accelerate cross-partner collaboration for measurement. This privacy-first, shared environment enables interoperable data analysis, eliminating custom clean room development complexities. It allows advertisers, publishers, agencies and partners to securely collaborate at scale by bringing their own data and logic. Addressing the fragmented landscape, Snowflake offers a neutral, open infrastructure to rapidly establish clean rooms, standardize collaboration and achieve continuous and transparent measurement across platforms while maintaining data control, fostering a new era of media accountability and efficient ecosystem operation.

Join Snowflake and partners on June 17 for an exclusive Data Clean Rooms brunch on our yacht. Register here.
