AI infrastructure that transforms how the world buys media

Every campaign you see online was set up by someone, by hand. A trader with six tabs open, copying the same budget, the same audience, the same naming convention into Meta, then Google, then TikTok, then DV360. Checking it twice. Fixing it at midnight when one field was wrong. The industry spent fifteen years making ads smarter, and almost no time on the people who actually launch them.

Nathan saw it from the media side: he built Manadge and sold it to iHeartMedia in 2023. Nicolas and Antoine saw it from inside the machine: they ran engineering at Veepee and built the bidder at Adot, the kind of system that decides in milliseconds where an ad goes. One side had the strategy. The other had the infrastructure. Nobody had joined the two.

In January 2026, in Paris, the three of them started Concord on one conviction: media buyers should not spend their days clicking buttons and filling out forms. Their job is the plan, the judgment, the client. Execution should be something software does, checked every time, under the control of the people who own it.

Two months after launch, Concord raised $3M from founders who built and sold ad tech. Today it is a team of 12 in Paris and New York, connected to Meta, Google, TikTok, Snapchat, DV360 and Amazon. And it is just getting started.
