The organisation behind the Raspberry Pi now consists of two arms. Originally developed under the auspices of the Raspberry Pi Foundation, the success of the Pi Model B prompted the Foundation to set up Raspberry Pi Trading, with Dr Eben Upton as CEO, to develop the third model, the B+. Raspberry Pi Trading is responsible for developing the technology while the Foundation is an educational charity that exists to get that message out to schools. Raspberry Pi Trading reinvests about a third of its profit in R&D, and the rest goes to the foundation.{{citation needed|date=November 2017}}
