Employees could choose to work on projects that interested them (open allocation), but the chief executive set salaries.

As a result of the scandal, Tom Preston-Werner resigned from his position as CEO.

In July 2015 GitHub raised another$250 million of venture capital in a series B round. Investors were Sequoia Capital, Andreessen Horowitz, Thrive Capital, and other venture capital funds.
