Havas has announced the acquisition of Unnest, a French data engineering and consulting firm known for its strong capabilities in designing, building, and implementing advanced data platforms. The move marks a significant boost to Havas Media Network’s global data and analytics division, CSA, aligning strongly with Havas’ Converged.AI strategy to support brands undergoing digital and AI-driven transformation.
Founded in 2021 by Nicolas Chollet and Mehdi Moreau, Unnest has quickly become a trusted partner for large-scale projects due to its deep expertise in Data & Cloud Engineering across platforms like Google Cloud, Azure, Amazon Cloud, and Snowflake. The company’s specialist knowledge and AI capabilities make it a high-value addition to Havas’ Business Science offerings.
The acquisition enables close collaboration with CSA Data Consulting, DBi, and TED Consulting, creating a combined force of 120 data experts in France. Supported by CSA’s global ecosystem, Unnest’s solutions will be expanded across international markets and various industries including retail, travel, beauty, luxury, and automotive.
Despite the acquisition, Unnest will maintain its independent mindset and technological agility while benefiting from Havas’ global client base and strategic partnerships.
Havas Chairman and CEO Yannick Bolloré said the addition will accelerate AI-driven growth, while Havas France Chief Data Officer Yoann Denée highlighted the enhanced ability to deliver advanced automation and analytics solutions. Unnest co-founder Nicolas Chollet shared optimism about scaling innovation in a rapidly evolving AI landscape.
