Frans de Kock

President and Co-founder of GMC

Frans is the Game Changer. Frans and the founding members created the company on the belief that lasting solutions in companies only happen as the result of a Whole System approach. His 36-year tenure in the mining industry has allowed him to refine the GMC model which has identified $21.2 billion NPV for clients since its inception in 1997. Frans is a champion for Whole System Optimization and believes that if there is more value in a client’s core process, GMC will find it. To ensure continued optimization for his clients, GMC has now developed first-to-market leave-behind software, INSIGHTIZE™ which combines innovative core process design, simulation and modeling with advanced analytic technology to support executive decision-making.

In 1994, he started a mining consultancy in Johannesburg, MineNet (Pty) Ltd, and in 1997, whilst retaining control of MineNet, Arthur became one of the founding members of GMC.
