The move will strengthen Havas Media Network’s data, technology and analytics arm CSA.

Founded in 2021 and headquartered in Paris, Unnest specialises in technology infrastructures and in designing, building, and deploying data platforms. The company employs teams focusing on data and cloud engineering (including Google Cloud Platform and Azure) and AI.

Havas will integrate Unnest’s expertise into its group Business Science practice, creating a combined team of 120 data professionals, based in France. Founders Nicolas Chollet and Mehdi Moreau and the Unnest employees will all join Havas.

The financial terms of the acquisition have not been disclosed.

Yannick Bolloré, chair and chief executive, Havas, said the Unnest team’s expertise would be “a valuable addition” to accelerate the group’s AI strategy.

Bolloré added: “They will help drive the adoption of AI solutions across our client base, addressing strategic and operational challenges while maintaining the highest standards of excellence.”
