GitHub

GitHub was founded in 2008 with the goal of facilitating collaboration between software developers. In time, it grew into one of the world’s largest repositories of code. Sequoia led GitHub’s $250 million Series B financing round in 2015 and is its second-largest outside investor. Another Silicon Valley heavyweight, Andreessen Horowitz, is the largest, with at least 13.33%; its stake in GitHub is worth more than $1 billion. Thrive Capital, cofounded by Josh Kushner (the brother of presidential advisor Jared Kushner), is also a significant shareholder. In all, the company has raised $350 million. In 2014, Tom Preston-Werner resigned from the firm following a harassment investigation. Chris Wanstrath told Forbes that he planned to step down as CEO as soon as he could find a replacement. Following the buyout, he will be succeeded by Nat Friedman, a Microsoft vice president. He will stay on as a technical fellow at Microsoft.
