He is founder, MD, board member, advisor, or investor to a wide variety of companies in the global technology sector.

Growing up on a farm, he decided not to complete high-school and instead made the move to the city of Cape Town alone, to pursue his dreams of being an Internet entrepreneur.

Having founded his first startup attempt at the age of 18, Justin has been involved in tech startups and entrepreneurial endeavours ever since.

Despite years of struggles and false starts in the wake of the dotcom crash in 2001, he ultimately went on to successfully launch and grow a pan-African Internet based software company from a garage in the suburbs of Cape Town.

He is today the co-founder and MD of 4Di Group, a diversified investment management group and family office, and co-founding General Partner of early-stage technology venture capital firm 4Di Capital, as well as an active angel investor in Africa and around the world.

As co-founder and inaugural Steering Committee Chairman of the Silicon Cape Initiative in 2009, designed to highlight and catalyse South Africa's nascent emerging tech startup ecosystem, Justin fully believes in South Africa’s potential as a global technology innovation hub.

In 2011, he was listed by the Mail & Guardian for the 'Top 200 Young South Africans', in 2013, listed by Forbes for '30 Under 30: Africa's Best Young Entrepreneurs', and in 2014, 2015 and 2016, listed by the Institut Choiseul for the 'Choiseul 100 Africa: Economic Leaders for Tomorrow'. In 2017 he was listed in the inaugural '100 Most Influential Young South Africans' by Avance Media.
