Following claims of harassment from former GitHub employee Julie Horvath, president and former chief executive Tom Preston-Werner has resigned.

On GitHub’s company blog, current CEO Chris Wanstrath writes that although Preston-Werner is stepping down, GitHub’s “investigation found no evidence to support the claims against Tom and his wife of sexual or gender-based harassment or retaliation, or of a sexist or hostile work environment.”

Chris Wanstrath replaced Tom Preston-Werner as CEO back in January. At the time, it was announced that Preston-Werner would focus on R&D and “new growth opportunities.”

It appears GitHub is trying to move on from the incident — at least publicly. Wanstrath writes that the company is “implementing a number of new HR and employee-led initiatives as well as training opportunities to make sure employee concerns and conflicts are taken seriously and dealt with appropriately.”

“We know we still have work to do,” Wanstrath adds.
