Kimbal Musk

Musk grew up with his brother Elon, sister Tosca, and many cousins. His mother, Maye Musk, was a prominent dietician and his father had his own engineering practice. After finishing high school in Pretoria, South Africa, Musk left to meet his brother in Kingston, Ontario, Canada and enrolled in university to pursue a degree in business at Queen's University. While in school, Musk first worked at Scotiabank. He graduated with his degree from Queen's University in 1995.

Musk's first entrepreneurship venture was a residential painting business with College Pro Painters in 1995, the same year he and his elder brother, Elon started their second company, Zip2. Zip2 Corporation 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. Musk was an early investor in his brother's venture X.com, an online financial services and email payments company. X.com merged with PayPal, which in October 2002 was acquired by eBay for $1.5 billion in stock.

While Elon stayed in California, Kimbal moved to New York and enrolled into the French Culinary Institute in New York City. In April 2004, Musk opened The Kitchen Boulder, a community bistro in Boulder, Colorado with Jen Lewin and Hugo Matheson. The Kitchen has been named one of "America's Top Restaurants" according to Food & Wine, Zagat’s, Gourmet, OpenTable, and the James Beard Foundation. In addition to its flagship in Boulder, Col., The Kitchen has locations in downtown Denver and Chicago.

From 2006 to 2011 Musk served as the CEO of OneRiot, an advertising network for the real-time, social web. In September 2011 Walmart-Labs acquired OneRiot for an undisclosed purchase price.

In 2011, Next Door American Eatery opened in downtown Boulder as an Urban Casual, American eatery and is located right next door to the west of the original restaurant on Pearl Street Mall. Next Door American Eatery is a growing restaurant concept with ten locations as of 2019.

After seven years of supporting the Growe Foundation to plant school gardens in the Boulder community, in 2011 Musk and Matheson established Big Green (originally named The Kitchen Community), a 501c3 nonprofit to help connect kids to real food by creating dynamic Learning Garden classrooms in schools across America. Learning Gardens teach children an understanding of food, healthy eating, lifestyle choices and environment through lesson plans and activities that tie into existing school curriculum, such as math, science and literacy.

Each of The Kitchen restaurants donates a percentage of sales to help plant Learning Gardens in their local community. In 2012, Big Green built 26 gardens in Colorado, 16 in Chicago, and 12 more around the USA.

In December 2012, Chicago Mayor Rahm Emanuel handed Musk's nonprofit $1 million to install 80 Learning Gardens in Chicago city schools. On February 2, 2015, The Kitchen Community celebrated its 200th Learning Garden build at Camino Nuevo Charter Academy, a high school in Los Angeles Unified School District which also marked the District's first SEEDS Project.

By the end of 2015, four years after its founding, The Kitchen Community had built 260 Learning Gardens across Chicago, Denver, Los Angeles and Memphis. In 2016, Musk co-founded Square Roots, an urban farming company that grows organic food in shipping containers. The company formed a partnership with Gordon Food Services (GFS) to expand outside of NYC. In January 2018, The Kitchen Community (TKC), expanded into a national nonprofit called Big Green and announced its seventh city, Detroit, to build outdoor Learning Garden classrooms in 100 schools across the Motor City. As of 2019, Big Green is in seven American cities with nearly 600 schools across its network impacting over 300,000 students everyday. Musk and Big Green have established Plant a Seed Day, an international holiday.

Musk married Jen Lewin with whom he established his business venture, The Kitchen. The couple had two children, but were later divorced. He lives in Boulder, Colorado. In April 2018, he married Christiana Wyly, an environmental activist and the daughter of billionaire Sam Wyly.

Musk faced scrutiny in 2020 after changing his Next Door's Family Fund program in the middle of the coronavirus pandemic. The fund was originally set up to help employees during an emergency situation. Contributions came from employees of Next Door.
