Musk grew up with his older brother Elon, younger sister Tosca, and many cousins. His mother, Maye Musk (née Haldeman), is a model and dietitian born in Saskatchewan, Canada, and raised in South Africa. His father, Errol Musk, is a South African electromechanical engineer, pilot, sailor, consultant, emerald dealer, and property developer, who partly owned a rental lodge at the Timbavati Private Nature Reserve. After finishing high school in Pretoria, South Africa, Musk left to meet his brother in Kingston, Ontario, Canada, and enrolled at Queen's University to pursue a degree in business. While in school, Musk first worked at Scotiabank. He graduated with his degree from Queen's University in 1995.

Musk's first venture was a residential painting business with College Pro Painters in 1994, the same year he and his elder brother, Elon, started their second company, Zip2. Zip2 was an online city guide that provided content for the new online versions of The New York Times and the Chicago Tribune newspapers. The company was sold in 1999 to Compaq for $307 million.

After selling Zip2, Musk invested in several young software and technology companies.
