Nancy Dubuc, the chief executive of Vice Media, who attempted to improve the company’s culture and steady its finances after taking over nearly five years ago, is stepping down, she said in an email to employees on immediately Friday. February 24 2023. Dubuc joined Vice Media in 2018, replacing Shane Smith, the brash chief executive who struck a series of deals that drove the company’s valuation ever higher but left it with onerous financial obligations to its increasingly anxious investors. She joined shortly after investigations into the company’s culture revealed incidents of sexual harassment against women who worked for the company.
