About Harmco Dejong’s Current Company
Vivienne Court Trading

Vivienne Court Trading Pty Ltd (VivCourt) is a proprietary trading company headquartered in Sydney, Australia. Founded by Rob Keldoulis in 2011, VivCourt trades a diverse range of asset classes using its proprietary technologies, market-leading coverage and global connections. VivCourt operates across all trading styles including market making, quantitative trading and positional trading, with a focus on APAC markets. VivCourt is reimagining the purpose of a trading firm. Their mission is to create a people-first culture that allows people to be authentic and curious, ask questions, and work autonomously. Additionally, VivCourt is driving social change, challenging the finance industry with the company's socially conscious approach. Rob Keldoulis, reflects on the company's origins “Trading can be a wonderful career, but there’s no function to it other than to make money... I wanted to know if it was possible to take what is basically the most capitalist job in the world and create purpose out of it. Could trading become something that also helped make the world a better place?” Since its inception in 2011, VivCourt has steadily grown and established itself as a pioneer in the financial world. Dedicated to maintaining its edge, VivCourt is in pursuit of top-tier traders and technologists, those with the right mix of skill and attitude, to delve into uncharted markets and set new benchmarks in the industry. A testament to our prowess, the Japan Exchange Group (JPX) has honoured VivCourt as the Best Market Maker in Outstanding ETF Market-Making Performance for three consecutive years.
