RISK101 MANAGEMENT

JONATHAN ELLENBERGER

Founding Director, CEO

 

Jonathan gained extensive experience in trading and risk modelling at the Johannesburg Stock Exchange during the 1980s.  Whilst establishing the fixed interest derivative desk for one of the broking houses, he identified the need for a reliable derivative pricing system. In 1987, RATT-Pac, the origin of the Risk 101 brand, was launched.  In 2004 Jonathan opened the Australian office. He is currently based in London where he heads up the UK-Europe division of Risk 101 and oversees the global portfolio.
