business_handshakeFor 55 years, and over 3 generations, the Maister family built, operated and then successfully sold what was one of the largest privately-owned corporations in Africa. The cornerstone of the group – Yellow Pages South Africa – proved to be one of the most successful and innovative publishing operations worldwide of its time.

Since then, the Maister family established a dynamic Family Office, that will ensure that future generations participate in and enjoy the opportunities created by this wealth.

MFO Investments, through its corporate entities, now manages a broad range of investments in Australia and internationally.

Our aim is to grow our capital through an investment approach that focuses on creating long-term value.

Our activities include seeking out high-quality investments for inclusion in our portfolio.
