Jason Holtman has left Valve, Develop understands.
A reliable source has told us Valve's director of business has departed the company, although it is currently unclear as to the reasons for his exit.
In early 2012 Ellsworth was hired by Valve Corporation (along with several other notable hardware hackers) to work on gaming hardware. Ellsworth was fired the following year.
