West Data Festival: Artificial Intelligence Takes Over Laval
Launched in 2019 by Laval Mayenne Technopole, the West Data Festival was born from the desire to raise awareness among companies in the Grand Ouest region about the challenges of data and artificial intelligence. In just a few editions, the event has established itself as the essential professional meeting place for anyone interested in the digital transformation driven by data and AI in Western France.
A Dense and Concrete Program
The West Data Festival stands out for the richness and diversity of its program, built around thematic conferences, practical workshops, feedback from companies that have deployed data and AI projects, technological demonstrations, and networking events. Each edition explores key themes: generative AI, AI agents, industry 4.0, cybersecurity, no-code, augmented human resources, data-driven commerce and marketing, and data for performance.
An Event Designed for Professionals
The festival primarily targets business leaders, digital transformation directors, data scientists, developers, IT managers, and public decision-makers. The first two days are dedicated to professionals, with a dense program of conferences and workshops. The third day is more broadly open to the general public, students, and the curious wishing to discover the concrete applications of AI and data.
Key Highlights
Among the festival's flagship events are the Women in AI Award, which highlights the inspiring journeys of women driving artificial intelligence forward in France, and the AI Trial, a fun and stimulating exercise that examines the ethical and societal issues of these technologies. The After WDF, a festive and friendly evening, allows participants to extend discussions in a relaxed atmosphere conducive to networking.
An Exhibition and Demonstration Space
The exhibition brings together dozens of exhibitors each year—startups, software publishers, consulting firms, research laboratories, and institutions—who present their solutions and innovations. Visitors can test tools, attend live demonstrations, and interact directly with the designers of data and AI solutions.
Exponential Growth
Despite disruptions related to the health crisis (the 2022 edition was split into two parts), the West Data Festival has experienced remarkable growth in terms of attendance, recognition, and program quality. Each year, the event confirms its status as the leading data and AI festival in the West, attracting an ever-larger audience and renowned national and international speakers. With over 2,200 visitors in the 2025 edition, the festival continues its ambitious development.
