Former GitHub CEO leaves the company

Tom Preston-Werner — founder of the immensely popular social coding site GitHub and its most prominent executive — has left the company in the wake of widely publicized sexual harassment investigation.

GitHub, a tech-industry darling whose coding software is used by millions of developers worldwide, launched the investigation last month after one of the company’s developers, Julie Ann Horvath, quit the company and claimed it had an oversized tolerance for inappropriate behavior.

Horvath’s allegations, published last month on TechCrunch, kicked off a debate over whether Silicon Valley’s tech companies are genuinely unfriendly toward women. In her TechCrunch article, Horvath said she was bullied after spurning one GitHubber’s sexual advances, and then harassed by the wife of a company founder, presumably Preston-Werner’s wife, Theresa.
