Louis de Waal (70)


BA (Law, Literature and Political Science)

Louis is a seasoned business man with some 40 years of experience in various service industries. These include advertising, car rental, and politics amongst others.

Highlights are 19 years in management consulting and 5 years during the formative years of the PSG Group Ltd, an investment holding company listed in the top 40 of the JSE featuring subsidiaries in agriculture, education, financial services, private equity and others.

When with the PSG Group, Louis was MD of PAG Placements, a JSE listed entity which served as the springboard for the group’s later spectacular growth. He was also involved in PSG Specialised Lending, the group’s entry vehicle into microlending which, in later years, culminated in the formation of the highly successful, Capitec Bank.

His career includes a 5 year stint in national politics from 1989 -1994 as Democratic Party MP for Northrand, the largest constituency within the old South African political dispensation, having won the seat from the NP.

Louis brings strategic knowhow, business perspective and lateral thinking which impact upon the risk assessment ability so needed in an entrepreneurial venture like Dewvest. “I believe that few things in business focus one’s mind as clearly on a daily basis as knowing that your own balance sheet is on the line, particularly if you sense that you won’t be able to rebuild it should the venture fail”, says Louis.
