Graeme Goldsworthy (1962) and Diederik Stolk (1983) have been working together for the past decade. In 2014 they founded Goldsworthy, Stolk & Associates with the belief that service personnel need better exercises in order to meet the challenges of future combat and relief operations. 

Graeme Goldsworthy is a wargamer, a veteran (UK Armed Forces), a mine specialist and a humanitarian. He has multiple operations and foreign postings on his name. 

Diederik Stolk has a background in simulation design, war-gaming, scenario-writing and strategy. He has worked for various government agencies, NGOs and multinationals.
