After college, Newmark worked at IBM for 17 years as a programmer, living in New Jersey, Boca Raton, Florida and Detroit. In 1993, he moved to San Francisco to work for Charles Schwab, where he was introduced to the Internet—which at that time was still relatively free of commercials. A self-professed nerd, he developed Craigslist as a free marketplace where people could come together – without charge – and exchange information. It has been described as an "internet commune." Newmark remains active at Craigslist in customer service, dealing mostly with spammers and scammers. He also operates Craigconnects, a site that publicizes charitable organizations.
Philanthropy
In 2006, he donated $20,000 to a non-profit group, NewAssignment.Net, an attempt to combine the work of amateurs and professionals to produce investigative stories on the Internet. In 2011, he introduced craigconnects to support non-profits and other organizations "that get things done on a sustainable basis." He declared it "the biggest thing in my life." In January 2017, TechCrunch reported that Newmark donated $500,000 to Wikipedia's attempt at "reducing harassment and vandalism on the site and improve the tools moderators use every day to keep the peace." In August 2018, Newmark donated $1 million to Mother Jones to help the magazine combat fake news. Through Craig Newmark Philanthropies, Newmark has contributed more than $40 million to journalism initiatives since 2015. In 2017, he donated $1 million each to ProPublica and the Poynter Institute. He made a $20 million endowment to the CUNY Graduate School of Journalism, which was subsequently renamed the Craig Newmark Graduate School of Journalism. Newmark also has a private charitable foundation, to which he contributed $50 million in 2016. Newmark's foundation supports military families, voter registration efforts, and women in technology. In 2018 Newmark's donations totaled $143 million. In 2019, he donated $6 million to Consumer Reports to fund a Digital Lab focused on consumer privacy rights and digital security. Newmark has served as an advisor or board member for the Sunlight Foundation, the Electronic Frontier Foundation, the Electronic Privacy Information Center, Rock the Vote, Voto Latino, the Tech Policy Summit, the Center for Public Integrity, the Center for Investigative Reporting, PolitiFact, Consumers Union and Girls Who Code.
Personal life
Newmark splits his time between San Francisco's Cole Valley and the West Village in New York City. He describes himself as a non-practicing, secular Jew, joking that his rabbi was the late singer Leonard Cohen. Newmark married Eileen Whelpley in December 2012.
Net worth
In May 2017, Forbes estimated that Newmark's net worth is at least $1.3 billion based on his ownership of at least 42% of Craigslist. He called a prior $400 million Forbes estimate of his net worth "bogus." In an interview published in 2017 he said that "By monetizing Craigslist the way I did in 1999, I probably gave away already 90 percent or more of my potential net worth." Newmark has described his business philosophy as "minimal profit" rather than non profit: "Basically I just decided on a different business model in '99, nothing altruistic. While Silicon Valley VCs and bankers were telling me I should become a billionaire, I decided no one needs to be a billionaire — you should know when enough is enough. So I decided on a minimal business model, and that's worked out pretty well. This means I can give away tremendous amounts of money to the nonprofits I believe in."
Politics
In 2014, he was one of 60 Democratic Party donors who urged the creation of a system of public election funding. In 2016, Newmark joined with the progressive RAD Campaign and Lincoln Park Strategies to commission a poll examining user perceptions about social media conflicts during the 2016 election year. Newmark has donated to the presidential campaign of Democratic Senator and former United States Secretary of StateJohn Kerry. He also supported former President Barack Obama. In 2015, Variety reported that he contributed to the presidential campaign of Hillary Clinton.
