datacraft workshop: REX: How we deployed AI coding assistants to 80+ developers in a large enterprise—challenges, adoption, gains, and key lessons for future scaling.

Adrien Maret, Core team member at H Company and Hubert Grégoire CTO at exFabrica

In this session, datacraft shares their return of experience (REX) on deploying AI coding assistants to over 80 developers within a large enterprise. They begin by presenting the context, the initial objectives, and the methodology used to roll out the solution at scale. We then walk through the deployment journey, highlighting key challenges, adoption strategies, and developer feedback. Finally, they detail the measurable results—both in terms of productivity and quality—and reflect on the gains, lessons learned, and areas for continuous improvement.
