Yaccarino joined X as CEO in May 2023, following Musk’s acquisition of Twitter for $44bn.
Prior to her role at X, she was instrumental in leading NBCUniversal’s global advertising operations.
Her responsibilities at X included managing business operations and addressing advertisers’ concerns amidst significant changes to the platform’s safety and content moderation policies.
During her leadership, X launched several initiatives to evolve into the “Everything App” Musk envisioned.
These included collaborations with Visa for direct payment solutions and the introduction of a smart TV app. The company was also considering the introduction of an X credit or debit card.
Yaccarino’s departure comes amid ongoing issues in Musk’s business portfolio, including declining sales at Tesla and controversies related to AI technologies.
In February 2025, Canada’s privacy watchdog initiated a probe into X for potential breaches in AI training data usage.
Tesla is experiencing its own executive turnover. Recent departures include Omead Afshar, a close associate of Musk, and North America HR Director Jenna Ferrua, Reuters reported.
