A lawsuit filed Wednesday accuses a Silicon Valley venture capitalist of sexually assaulting a 29-year-old entrepreneur during a red-eye flight while telling her that he had the power to “make or break” her career.

Rachel Danae Vachata, who recently made Forbes “30 Under 30 in Healthcare” list, alleges in the civil suit that Lanza techVentures managing director Lucio Lanza groped her right breast, attempted to kiss her, and put his hand in her crotch while on an overnight flight from San Francisco to Minneapolis in July 2017.
