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. From 2006 to 2011, Musk served as the CEO of OneRiot, an advertising network. In September 2011,
Walmart-Labs acquired OneRiot for an undisclosed purchase price. On 9 February 2021, Musk sold 30,000 shares of
Tesla, Inc. worth $25.6 million. On 24 February 2022, it was reported that the SEC was investigating Musk for possible insider trading violations after he sold 88,500 shares of Tesla, valued at $108 million, one day before his brother put out a poll on Twitter asking if he should sell 10% of his Tesla shares. As a result of that poll, Elon Musk sold billions of dollars of Tesla shares and the stock price sank. In 2022, Kimbal Musk became an entrepreneur in multi-drone coordinated aerial displays. Through the holding company Nova Displays he bought the Intel multi-drone coordinated aerial displays subsidiary and nine thousand drones.
Restaurateur 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, a community bistro in
Boulder, Colorado with
Jen Lewin and Hugo Matheson. In addition to its flagship restaurant in Boulder, The Kitchen has locations in
downtown Denver and Chicago. In 2011, Next Door American Eatery opened in downtown Boulder as a fast casual American eatery. 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 its local community. In 2012, Big Green built 26 gardens in Colorado, 16 in Chicago, and 12 more around the United States. In December 2012, Chicago Mayor
Rahm Emanuel handed Musk's nonprofit $1 million to install 80 Learning Gardens in Chicago city schools. 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 As of 2019, Big Green is in seven American cities with nearly 600 schools across its network impacting over 300,000 students every day. Musk and Big Green have established Plant a Seed Day, an international holiday.
The Family Fund Kimbal Musk's restaurant group collected funds (called the Family Fund) from employees to cover hardships and personal emergencies, but during the
coronavirus pandemic of 2020, the restaurants closed "permanently" and the employees were locked out of the funds they had contributed to. Later, the restaurants reopened but reportedly did not restore the fund to those who contributed. Musk later disputed reports of the controversy, citing lack of facts by journalists. The Kitchen Restaurant Group reports the fund now receives contributions from owners and customers; as tips for take-out orders are rerouted to the fund and then matched by the owners. The group also reports that grants have been awarded and both furloughed and laid-off workers will be considered in future. ==Personal life==
