Proof Engineering (Pty) Ltd was established in 1978 in Johannesburg, South Africa. Steadfastly retaining its original entrepreneurial and innovative roots, the company achieved many personal, as well as industry achievements. Consequently, it was inevitable for the company to attract local as well as international interest as potential investment opportunity. Gabosegangwe acquired 26% shareholding in 2004, thereby exceeding market requirements in achieving full BEE status well ahead of industry norms.
