When Product, Design, and Tech all adopt AI in parallel, we instinctively think about tools. I discovered through my experience at Criteo that the real challenge is profoundly human: aligning teams with different visions, different fears, and different territories to protect, into a shared workflow that actually makes sense.

This is the story of my transformation-building journey over the past year, within Product, for designers as a team.

In a world where almost everyone can do almost everything thanks to AI – in a company like Criteo, with 4,000 employees, 900 devs, 80 PMs, and 35 designers – how do you operate this AI transformation without it becoming a mess?
