Jennifer Witz
Jennifer Witz is the CEO of SiriusXM, the dominant force in satellite and streaming audio in North America, overseeing a platform that reaches tens of millions of subscribers and commands significant share of the audio advertising market. She ascended to the CEO role in 2021 after a long tenure at the company, bringing deep institutional knowledge of SiriusXM's business model, subscriber economics, and advertising revenue streams. Her leadership has been defined by efforts to modernize SiriusXM's ad tech capabilities, expand programmatic audio advertising, and position the company competitively against streaming rivals like Spotify and Apple Music. Witz spent over two decades building her career at SiriusXM and its predecessor entities, holding senior roles across marketing, sales, and business development before becoming CEO. Her rise through the organization gave her a comprehensive understanding of both the consumer subscription side and the advertiser-facing business, making her well-suited to navigate the dual-revenue model that defines SiriusXM's financial structure. Under her leadership, SiriusXM has invested in data-driven advertising solutions and audience targeting capabilities to attract brand advertisers seeking premium audio environments. In 2026, Witz and SiriusXM entered reported merger talks with iHeartMedia, a development that, if completed, would represent one of the most consequential consolidations in the history of audio media and advertising. Such a combination would create an unprecedented audio advertising powerhouse, combining SiriusXM's satellite and streaming reach with iHeartMedia's broadcast radio footprint and digital audio assets, fundamentally altering the competitive dynamics of the audio AdTech ecosystem.
