  • Christian Lanng was fired as CEO of Tradeshift in October following allegations of sexual assault and harassment 
  • A new lawsuit alleges that he subjected his assistant to years of ‘unwanted sexual horror’  
  • He allegedly forced her to sign a ‘sexual slave contract’ detailing sadistic sexual abuse and torture 

A fired San Francisco tech CEO is accused in a shocking new lawsuit of enslaving his assistant with a ‘sexual slave contract’ and subjecting her to ‘unwanted sexual horror.’ 

Christian Lanng, 45, the former head of billion-dollar software firm Tradeshift, allegedly forced an unnamed staffer, identified only as Jane Doe, into a ‘dark abyss’ of sexual abuse and sadistic torture. 

The lawsuit, reported by Mercury News, alleged Lanng inflicted ‘physical pain on her by various means, urinating on her and routinely penetrating her person with foreign objects.’ 

Lanng was fired from the Bay Area startup in October for ‘gross misconduct on multiple grounds’, with Tradeshift saying it made the decision following ‘serious allegations of sexual assault and harassment’ against the CEO.

Lanng was fired from Tradeshift in October for ‘gross misconduct on multiple grounds’ following ‘serious allegations of sexual assault and harassment’ against the CEO 

The lawsuit was filed Thursday in San Francisco County Superior Court against Lanng and Tradeshift, claiming the abuse started within months of her being hired at the tech firm. 

Tradeshift, a cloud network that services over 1.5 million businesses, did not immediately respond to a request for comment when contacted by DailyMail.com. Lanng could not be reached. 

A copy of the alleged slave contract reported by Mercury News was purportedly nine pages long, and included provisions ordering Doe to serve as a sex slave for the CEO and perform demeaning tasks while at work. 

This reportedly saw her instructed to be ‘always sexually available for her master when he needs sex and to never refuse him sex even when not wearing the collar.’ 

Another stipulated that whenever she saw Lanng ‘in private for the first time, she is to kneel and ask if there is anything she can do for him.’ 

In one chilling order in an ‘at work’ section of the lawsuit, Doe was told she was free to ‘act independently as long as she remembers she is her master’s property and she is there to please him and for no other reason.’ 

It is also claimed that she was given mandatory sex acts to complete, had to keep her weight between 130 and 155 pounds, and was ordered to dress in ‘a proper, feminine way, preferably skirts, dresses and stockings.’ 

She was reportedly given a ‘day collar’ to wear when out with Lanng’, and the alleged contract said he would ‘work to shape the slave towards his goal of the perfect woman.’

The purported contract allowed ‘any punishment the master decides to inflict, whether earned or not’, which allegedly included spanking, slapping and electric shocks. 

The alleged contract cited Lanng’s ‘responsibility’ not to kill Doe or inflict permanent bodily harm as he doled out the punishments. 

‘The slave agrees to always taking her punishments without being angry, sullen or frustrated with her master and thank him after,’ the document allegedly ordered. 

Doe also claims she was ‘beat to the point of bleeding’, and she was abused with ‘inanimate objects.’ 

The lawsuit alleges that Lanng forced Doe to deep a ‘diary’ of ‘his subjugation and enslavement of her’, and he would ‘beat Jane Doe with a cane if she did not write submissive entries in the ‘diary.” 

Lanng has previously denied allegations of sexual misconduct following his firing, telling TechCrunch in October: ‘There has never been an HR case, complaint or formal allegation filed against me at Tradeshift.’ 

However, Doe alleges that she did tell the company’s human resources department and warned officials about her ‘suffering at the hands of the CEO under the slave contract’, per the lawsuit. 

The filing claimed that Doe signed the ‘slave contract’ because she ‘loved her job, was accomplishing important work in her new role and did not want to lose the opportunity to work a Tradeshift.’

However, she claims that the firm retaliated to her filing a complaint by firing her in 2020. It is unclear how long she had worked at the company. 

Doe alleges that she tried to leave the contract several times over the years, ‘but when she did, Lanng would become enraged, even violent.’ This allegedly included one incident where Lanng assaulted her in Davos, Switzerland. 

The lawsuit also reportedly included Tradeshift’s termination letter to Lanng, which cited ‘a pattern’ of sexual misconduct allegations against him. 

It allegedly claimed the firm was in possession of ‘detailed evidence’ from a different woman, but Lanng had failed to pay a settlement agreement in May 2022. 

Doe also claims in her lawsuit that she is in contact with ‘other victims… in connection with Lanng, under the aegis of Tradeshift.’ 

Lanng’s alleged years-long ordeal left Doe ‘bedridden and in a precarious psychological state for almost two years, and she continues to suffer from PTSD. 

The lawsuit claims she has spent hundreds of thousands of dollars of medical and therapeutic care, and now ‘bears numerous scars and bodily damage, remnants from the actual, physical sexual torture she endured at Lanng’s hands while an employee at Tradeshift.’
