Silicon Valley investor Shervin Pishevar, known for his early bet on Uber Technologies, said on Thursday that he would sever ties with his venture capital company, Sherpa Capital, after being accused of sexual misconduct.

Pishevar, who has denied the accusations, said in a statement provided by his lawyer that he was voluntarily leaving Sherpa Capital, which he co-founded, because of ongoing “untruthful attacks” against him.

Bloomberg reported in November that five women accused Pishevar of exploiting a professional connection or the prospect of a job, mentorship or investment to make unwanted sexual advances.

Reuters was unable to independently confirm the accusations.
