Work Background
Grinaker TechnologiesFounder & CEO
Jun. 2021South AfricaIn 1931 my late grandfather, Ole Grinaker, founded the Grinaker construction company, now formally known as Aveng Grinaker LTA. Over the years he grew the company to the largest, privately-own construction company in South Africa, before listing on the JSE in 1964. Fast-forward nearly 60 years to 2021, I have founded Grinaker Technologies - a company with similar goals and values, but in a different industry. Grinaker Technologies provides both hardware and software solutions, backed by a focus on delivering sticky, world-class user experiences and a goal to make a positive impact in the world, big or small.
