Damien Viel

Operator

Damien Viel is a seasoned media and digital advertising executive best known for steering Twitter's French operations through significant transformation, including the platform's high-profile acquisition by Elon Musk and its rebranding to X. As Managing Director France, he has been the primary face of the platform to French advertisers, media agencies, and regulators, navigating advertiser uncertainty and brand safety concerns while maintaining commercial relationships in one of Twitter/X's key European markets. Viel joined Twitter France in 2015 and has built a reputation as a pragmatic operator capable of managing complex stakeholder relationships in a challenging media environment. His tenure has coincided with major industry shifts including the rise of programmatic advertising, evolving data privacy regulations such as GDPR, and the broader transformation of social media advertising. He has been a consistent voice representing Twitter/X's advertising proposition to the French market, engaging with trade bodies and industry forums. Before Twitter, Viel held roles in digital media and advertising, giving him a grounded understanding of both the buy and sell sides of the French digital advertising ecosystem. His longevity at Twitter/X — rare given the platform's significant executive turnover globally — speaks to his ability to adapt and maintain institutional relationships in a volatile environment.
