MrBeast's media company has been sued by a former employee over claims of sexual harassment and workplace gender bias.


The 27-year-old, real name Jimmy Donaldson, is the world's most-followed YouTuber and employs more than 500 people.


Lorrayne Mavromatis, a former executive who worked for his company Beast Industries from 2022 to 2025, claimed harassment of women employees was 'condoned' and complaints were not taken seriously at the business.


A representative for Beast Industries has described the allegations as 'categorically false' in a response to BBC Newsbeat.


Mavromatis first joined the company as its head of Instagram before being promoted.


In court documents, she claims she was fired after 'complaining about a workplace that suffered from a lack of basic employment protections'.


She alleges that sexual harassment of other female employees was 'both condoned and/or perpetuated by their supervisors,' adding that she was treated differently than her male counterpart.


Mavromatis says she was told her claims were 'unsubstantiated' when she complained about the 'hostile environment' she and other women were experiencing.


In one example cited in the lawsuit, Mavromatis claims former Beast Industries CEO James Warren suggested that she was not being collaborated with on projects due to her appearance being perceived as having a sexual effect on MrBeast.


She further alleges being 'promptly demoted and transferred to an obscure role known by [company] employees as the division where 'careers go to die'.


According to her complaint, Mavromatis was fired less than three weeks after returning from pregnancy-related leave.


She has suffered 'mental anguish, humiliation, embarrassment' and claims MrBeast's conduct has damaged her emotional and psychological well-being.


Mavromatis is seeking 'lost wages, lost benefits, reinstatement', and various forms of damages.


In an emphatic rebuttal, a Beast Industries representative has labeled the claims as a 'clout-chasing complaint' built on 'deliberate misrepresentations and categorically false statements'. They insist they possess extensive evidence, including messages, documents, and witness testimonies that unequivocally refute Mavromatis' claims.


The representative also clarified that the roles held by both men and women were eliminated during a reorganization of the entire team, denying any linkage between Mavromatis' firing and performance.


MrBeast, who has over 470 million subscribers, has faced legal scrutiny in the past, with accusations regarding his reality show, Beast Games, which he denied, stating such claims were exaggerated.


The controversy surrounding his company adds a complex layer to his rising fame and influence in the digital space.
