Shawn Parker

In 2017, during an interview with Axios, Parker expressed concerns about the role of Facebook in society, saying that it "exploit[s] a vulnerability in human psychology" as it creates a "social-validation feedback loop". Parker stated that he was "something of a conscientious objector" to using social media.

In November 2017, Science published a study from Parker Institute researchers at MD Anderson Cancer Center showing that melanoma patients who have specific types of bacteria and a greater microbial diversity in their gut microbiome responded better to an anti-PD-1 checkpoint inhibitor versus those with less diversity. Based on this work, the Parker Institute is collaborating with MD Anderson and industry partner Seres Therapeutics to launch a microbiome-cancer immunotherapy clinical trial for advanced melanoma patients.

Parker was also a driving force behind the Opportunity Zones provision in the Tax Cuts and Jobs Act of 2017 which are designed to incentivize investments in struggling American communities. In 2015, the Economic Innovation Group, which Parker co-founded, published a whitepaper on the idea of opportunity zones, and in 2017, a bill passing them into law was shepherded by a bi-partisan coalition involving Senator Cory Booker and Senator Tim Scott.

Parker donated $250 million to create the Parker Institute for Cancer Immunotherapy, in April 2016. The funds initially went to over 300 scientists at 40 laboratories, in 6 institutions.

Starting in 2016, the Parker Institute for Cancer Immunotherapy scientists funded a clinical trial to test the next wave of cancer-fighting T-cells engineered using the CRISPR gene-editing technology. The trial was the first in the United States to test CRISPR-modified cells in humans. The trial is led by the University of Pennsylvania and is also conducted at University of California, San Francisco and the University of Texas MD Anderson Cancer Center.

In June 2015, Parker announced a $600 million contribution to launch the Parker Foundation, which focuses on three areas: Life Sciences, Global Public Health and Civic Engagement. It takes an interdisciplinary approach to large-scale challenges, combining insight, capital, science and technology, organization building and public policy.

In February 2015, Parker was ranked number 5 on the Chronicle of Philanthropy's 2014 Philanthropy 50 list. In August 2018, Parker was nominated as a Wired Magazine "Icon" along with Alex Marson for his research in DNA programming and genome editing in the fight against cancer. He's also been named one of Town and Country's Top 50 Philanthropists and was named in Time Magazine's Healthcare 50 for his work in connecting cancer research. In 2016, he was given the "Pontifical Key Philanthropy Award" by Cardinal Gianfranco Ravasi at the Vatican for his cancer work.

In April 2014, Parker announced his backing of a new initiative called Brigade, an online platform for civic engagement to "combat a lack of political engagement and interest in all levels of government across America". Parker serves as the Executive Chairman of Brigade. The initial round of funding was $9.3 million from Parker, with additional sums from other investors. In 2014, Brigade acquired Causes, an online platform for social impact and political activism. Causes had in 2013 acquired Votizen, a political advocacy startup. Parker and The Founders Fund were a part of Votizen's $1.5 million funding round in 2010, and Parker served on the board of directors. He has stated, "Politics for me is the most obvious area [to be disrupted by the Web]."

In 2011, Parker became engaged to Alexandra Lenas, a singer-songwriter, and they were married in 2013. The couple has a daughter, Winter Victoria Parker, born on January 6, 2013, and a son, Zephyr Emerson Parker, born on December 1, 2014.

On June 1, 2013, Parker married Alexandra Lenas in Big Sur, California, in a wedding at which every guest was given a Lord of the Rings–style costume. The wedding purportedly cost $10 million to stage, though Parker describes this estimate as "WAY off base".

In 2011, Parker was a guest on Late Night with Jimmy Fallon, featured on the cover of the Forbes 400 issue, and was profiled in Vanity Fair.

Parker has made substantial donations to both sides of U.S. party politics; his allegedly "non-partisan" approach favors contributions to "elected officials who have shown themselves willing to work across the aisle". He favored Democrats as well as progressive causes such as campaign finance reform and gun control; he has spoken out in favor of higher taxes, particularly for the "wealthy and super wealthy," and in favor of higher capital gains taxes. Parker has also supported middle-of-the-road Republican candidates and super PACs, favoring "economically moderate" conservatives and candidates with a demonstrated interest in compromise and deal-making. In Washington, he has met with Republican lawmakers about ways of encouraging economic investment in struggling areas of the country. He has also supported cannabis law reform and in 2010, following the example of donations by Facebook co-founder Dustin Moskovitz (totaling $70,000) donated $100,000 to the 2010 California Proposition 19 campaign to legalize marijuana in that state and $400,000 to the Democratic Party backed 2016 California Proposition 63 campaign to require background checks for all ammunition purchases. Parker will donate $250 million to launch a new institute aimed at developing more effective cancer treatments by fostering collaboration among leading researchers in the field. For the 2016 presidential election, Parker created a social ballot guide for voters to help each other pledge to vote.

Parker was portrayed by Justin Timberlake in the 2010 film The Social Network. The movie is an account of Facebook's founding and early days.

While working at Founders Fund, Parker had been looking to invest in a company that could further Napster's music sharing mission legally. In 2009, a friend showed him Spotify, a Swedish streaming music service, and Parker sent an email to Spotify's founder Daniel Ek. The pair traded emails, and in 2010 Parker invested US$15 million in Spotify. Parker, who currently serves on Spotify's board, negotiated with Warner and Universal on Spotify's behalf, and in July 2011, Spotify announced its U.S. launch. At Facebook's f8 conference that year, Parker announced a partnership between Facebook and Spotify, which allowed users to share their Spotify playlists on their Facebook profiles.

In 2007, Parker founded Causes, originally one of the earliest Facebook applications, as a philanthropic service that uses social media to connect charities with their supporters and potential donors and then communicates that connection to the user's network of friends. By 2013, 186 million people had joined Causes, donating over $50 million to 60,000 non-profits.

In 2006, Parker became managing partner at Founders Fund, a San Francisco-based venture capital fund founded by Peter Thiel. Founders Fund is focused on investing in early-stage companies, has $500 million in aggregate capital, and has invested in Quantcast, Path, and Knewton. Parker was given carte blanche by Thiel when finding investments. In 2014, Parker stepped down from his role at Founders Fund to focus on other projects. Parker has also hosted The TechFellow Awards, a partnership between TechCrunch and Founders Fund that annually gives 20 entrepreneurs $100,000 each to invest in startups.

During a party in 2005, police entered and searched a vacation home Parker was renting and found cocaine. Parker was arrested on suspicion of drug possession, but was not charged. This event caused Facebook investors to pressure Parker into resigning as company president. Even after stepping down, Parker continued to remain involved with Facebook's growth and met regularly with Zuckerberg. The event was later dramatized in the movie The Social Network.

Since 2005, Parker has been an active donor to cancer research, global public health and civic engagement. In 2012, he pledged a $5 million grant to Stand Up to Cancer and the Cancer Research Institute to create the Immunotherapy Dream Team, uniting laboratory and clinical efforts that will lead to the immunological treatment, control and prevention of cancer. In December 2014, Parker pledged $24 million to create the Sean N. Parker Center for Allergy Research at Stanford. In 2015, he made a $4.5 million grant to support the Malaria Elimination Initiative at the University of California San Francisco's Global Health Group, and a $10 million grant to create the Sean N. Parker Autoimmune Research Laboratory at UCSF.

In 2004, Parker saw a site called "The Facebook" on the computer of his roommate's girlfriend, who was a student at Stanford. Parker had experience in the social networking industry as an early advisor to Friendster and its founder, Jonathan Abrams, for which he was given a small amount of stock in 2003. Parker met with Mark Zuckerberg and Eduardo Saverin, and a few months later joined the five-month-old company as its president. According to Peter Thiel, Facebook's first investor, Sean Parker was the first to see potential in the company to be "really big," and that "if Mark ever had any second thoughts, Sean was the one who cut that off."

In November 2002, Parker launched Plaxo, an online address book and social networking service that integrated with Microsoft Outlook. Plaxo was an early social networking tool, which would later influence the growth of companies like LinkedIn, Zynga, and Facebook. Plaxo was one of the first products to build virality into its launch, and that earned it 20 million users. Two years after founding Plaxo, Parker was ousted by the company's financiers, Sequoia Capital and Ram Shriram, in an acrimonious exit that reportedly involved the investors hiring private investigators to follow him.

When Parker was 15, he met 14-year-old Shawn Fanning over the Internet, where the two bonded over topics like theoretical physics and hacking. A few years later Parker and Fanning, a student at Northeastern University, cofounded Napster, a free file-sharing service for music. Parker raised the initial $50,000, and they launched Napster in June 1999. Within a year, the service had tens of millions of users. Napster was opposed by recording labels, the Recording Industry Association of America, and the heavy metal band Metallica, among others. Lawsuits by various industry associations eventually shut down the service. Napster has been called the fastest-growing business of all time, is credited with revolutionizing the music industry, and is considered by some to be a precursor to iTunes.

Parker attended Oakton High School in Fairfax County, Virginia for two years before transferring to Chantilly High School in 1996 for his junior and senior years. While there, Parker wrote a letter to the school administration and persuaded them to count the time he spent coding in the computer lab as a foreign language class. As a result, towards the end of Parker's senior year at Chantilly, he was mostly writing code and starting companies. He graduated in 1998. While still in high school, he interned for Mark Pincus (the CEO of Zynga) at Pincus's Washington D.C. startup FreeLoader. He won the Virginia state computer science fair for developing a Web crawler, and was recruited by the CIA. By his senior year of high school, Parker was earning more than $80,000 a year through various projects, enough to convince his parents to allow him to skip college and pursue a career as an entrepreneur.

Sean Parker (born December 3, 1979) is an American entrepreneur and philanthropist, most notable for co-founding the file-sharing computer service Napster, and serving as the first president of the social networking website Facebook. He also co-founded Plaxo, Causes, Airtime.com, and Brigade, an online platform for civic engagement. He is the founder and chairman of the Parker Foundation, which focuses on life sciences, global public health, and civic engagement. On the Forbes 2016 list of the world's billionaires, he was ranked #722 with a net worth of US$2.4 billion.
