How Gide Transformed Its Practice with AI: A Case Study in Successful Deployment
When a firm like Gide Loyrette Nouel — France's leading business law firm, 500+ lawyers, 10 offices worldwide — decides to deploy an AI solution across all its teams, it's not a simple software purchase. It's the result of a methodical, progressive transformation spanning over two years.
It All Starts with a Task Force
As early as 2023, Gide made a structural decision: forming a dedicated AI task force of nearly 100 potential users, including over 60 lawyers. Their mission was to experiment with emerging solutions, identify the right use cases, and separate media hype from real operational value.
Choosing Jimini AI: Sovereignty and Co-Creation
Among the solutions tested, Gide selected Jimini AI, a French startup specializing in legal AI. In the context of tightening GDPR requirements and growing concerns about the US Cloud Act, choosing a French provider represents a strong data sovereignty stance.
What sets this partnership apart is its co-development dimension. Gide and Jimini AI first signed a co-development partnership to design solutions tailored to real legal practice needs. As Raphaël Arroche, CEO and co-founder of Jimini AI, stated:
"This partnership illustrates a decisive turning point for the legal sector: artificial intelligence is no longer mere assistance, but a true lever for evolving practices."

From Pilot to Full Deployment: A Controlled Scale-Up
The transformation followed three distinct phases. First, a restricted pilot within specific teams. Then, extension to the 100 members of the AI task force. Finally, in October 2025, Gide officially deployed Jimini AI across all its lawyers, in France and internationally.
Frédéric Nouel, Senior Partner of Gide, framed the vision clearly:
"The transformation potential of AI is immense, provided it is well understood and mastered. We are equipping ourselves with the best AI tools to gain efficiency, while maintaining a clear awareness of their limitations."

What This Case Teaches Us
Gide's journey offers valuable lessons: validation by a top-tier firm signals the maturity of the French legal tech ecosystem. The progressive methodology — task force, pilot, extension, deployment — is a reproducible model. And the co-development approach represents a new paradigm where lawyers actively shape the tools they use.
