Co-founder & CEO of Reddit
Reddit, Inc.
Steve Huffman, who posts under the username 'spez', co-founded Reddit in 2005 with University of Virginia roommate Alexis Ohanian, and the site was sold to Condé Nast in 2006. He left in 2009 to start the travel company Hipmunk and returned as Reddit's CEO in July 2015, succeeding Ellen Pao. In November 2016 he admitted to secretly editing user comments in the pro-Trump subreddit r/The_Donald that insulted him, calling it a lapse in judgment. In 2023 he led Reddit's decision to begin charging for API access, which triggered a mass subreddit blackout; a leaked internal memo in which he told staff the protest 'will pass,' along with his characterization of moderators as 'landed gentry,' intensified the backlash.
Co-founder & former Executive Chairman of Reddit
Reddit, Inc.
Alexis Ohanian (Reddit username 'kn0thing') co-founded Reddit in 2005 with Steve Huffman after the pair were accepted into Y Combinator's first batch. He designed Reddit's alien mascot, Snoo, as a doodle while an undergraduate at the University of Virginia. After Reddit's 2006 sale to Condé Nast, he pursued other ventures including Hipmunk and the venture firm Initialized Capital, then returned full-time alongside Huffman in July 2015 before stepping back from day-to-day work in 2018. On June 5, 2020, following the murder of George Floyd, he resigned from Reddit's board and publicly urged the company to fill his seat with a Black candidate, later founding the venture firm Seven Seven Six.
Early Reddit team member, programmer & activist
Reddit / Infogami
Aaron Swartz (1986–2013) was an American programmer and internet activist who became associated with Reddit in November 2005, when Y Combinator suggested his startup Infogami merge with Reddit; the combined entity gave him the title of co-founder. He helped develop Reddit's codebase but left the company in 2007, the year after its sale to Condé Nast. Swartz went on to influential work on RSS, Markdown, Creative Commons, and progressive online activism, including campaigns against the SOPA bill. In 2011 he was arrested and federally indicted for mass-downloading academic articles from JSTOR via MIT's network; facing multiple felony charges and a possible lengthy prison sentence, he died by suicide on January 11, 2013, prompting widespread debate about prosecutorial overreach and computer-crime law.
Co-founder & former CTO of Reddit
Reddit, Inc.
Christopher Slowe (Reddit username 'KeyserSosa') holds a PhD in physics from Harvard and was Reddit's first employee, joining Steve Huffman and Alexis Ohanian out of Y Combinator's 2005 batch and helping build the site's early ranking and anti-spam systems. He is generally credited among Reddit's founding team and remained its longest-serving early employee until departing in 2010 to become chief scientist at Hipmunk. He returned to Reddit in 2017 and served as Chief Technology Officer, scaling the company's engineering organization through its growth years and its 2024 IPO. He has been described as one of the principal technical architects behind Reddit's platform.
Interim CEO of Reddit (2014–2015)
Reddit, Inc.
Ellen Pao is an American tech executive and investor who joined Reddit in 2013 and became interim CEO in November 2014 after Yishan Wong's departure. Her tenure included the introduction of anti-harassment policies and the banning of several abusive subreddits, which drew criticism from parts of the community. In July 2015 the abrupt dismissal of Victoria Taylor, the popular employee who coordinated Reddit's 'Ask Me Anything' interviews, sparked a user revolt sometimes called 'AMAgeddon' in which hundreds of subreddits went private in protest. Pao resigned days later, on July 10, 2015, and Steve Huffman returned as CEO; she has said she was made a scapegoat amid harassment (co-founder Alexis Ohanian was later identified as having made the Taylor call), and she went on to co-found the diversity nonprofit Project Include.
CEO of Reddit (2012–2014)
Reddit, Inc.
Yishan Wong is an American technology executive who served as CEO of Reddit from 2012 until his resignation in November 2014, having previously held engineering roles at PayPal and Facebook. During his tenure he articulated a strong free-speech position, stating that Reddit would not ban legal content even when staff found it 'odious,' while still introducing some moderation against harassment and illegal material. His leadership coincided with the high-traffic 2014 'The Fappening' episode and other content controversies. He resigned after the board declined to support his proposal to relocate Reddit's offices, and he later founded the reforestation startup Terraformation.
Investor & former Reddit board member
Y Combinator / OpenAI
Sam Altman, later widely known as CEO of OpenAI, was an early and significant figure in Reddit's financing and governance. As a member of Y Combinator's first batch he got to know Reddit's founders, and in 2014 he led Reddit's roughly $50 million Series B funding round. He briefly served as Reddit's CEO for about eight days in 2014 during the leadership transition and sat on Reddit's board until 2022, participating in multiple funding rounds (2014, 2015, and 2021). His longtime stake in Reddit became worth more than a billion dollars on paper after the company's 2024 public listing, and OpenAI later struck a data-licensing partnership with Reddit.
Chief Operating Officer of Reddit
Reddit, Inc.
Jen Wong is an American business executive who became Reddit's Chief Operating Officer in 2018, overseeing the company's business strategy, advertising, and revenue operations. She previously served as president of digital and COO at Time Inc., chief business officer at PopSugar, and head of business operations at AOL, and began her career at McKinsey & Company. Under her leadership Reddit substantially grew its advertising business as it moved toward profitability. She helped steer the company through its March 2024 IPO, the first major U.S. social media company to go public since 2019.
Chief Financial Officer of Reddit
Reddit, Inc.
Drew Vollero is a veteran finance executive who became Reddit's first Chief Financial Officer in March 2021 as the company prepared for a public offering. He had previously served as the first CFO of Snap Inc., where he led the Snapchat parent's 2017 IPO, and earlier spent roughly 15 years at toy company Mattel in finance and corporate-development roles. At Reddit he oversaw years of financial preparation before the company's eventual March 2024 listing on the New York Stock Exchange.
VP of Policy at Reddit
Reddit, Inc.
Jessica Ashooh leads policy at Reddit, serving as Director and later Vice President of Policy, overseeing the company's technology policy and trust-and-safety policy functions. Before Reddit, she was Deputy Director of the Atlantic Council's bipartisan Middle East Strategy Task Force and earlier worked as a senior analyst in the United Arab Emirates Foreign Ministry's Policy Planning Department. She holds a doctorate in international relations from Oxford as a Marshall Scholar and an undergraduate degree from Brown University. Her hire from a foreign-policy think tank drew some commentary connecting it to debates over Reddit's content policy, though such framing is largely opinion rather than established fact.
Former Director of Talent / AMA coordinator
Reddit, Inc.
Victoria Taylor was Reddit's director of talent and the chief coordinator of its popular Ask Me Anything (AMA) interview series, helping verify and run high-profile AMAs including one with President Barack Obama and serving as a key liaison between the company and its volunteer moderators. On July 2, 2015, she was abruptly fired; reporting linked the dismissal to disagreements over the direction and commercialization of the AMA program. Her removal, with no warning to the moderators who relied on her, triggered a mass protest dubbed 'AMAgeddon,' in which moderators set hundreds of major subreddits to private, effectively darkening much of the site. The backlash is widely seen as a flashpoint that contributed to then-CEO Ellen Pao's resignation later that month.
Former Reddit general manager
Reddit, Inc.
Erik Martin was the general manager of Reddit in 2013 during the period of the Boston Marathon bombing. After Reddit users on r/findbostonbombers wrongly identified innocent people, including missing student Sunil Tripathi, as bombing suspects, Martin issued a public apology on April 22, 2013, on behalf of the site. He acknowledged that activity on Reddit, though started with noble intentions, had fueled online witch hunts and dangerous speculation with negative consequences for innocent parties, and stated that Reddit had apologized privately to the Tripathi family. The apology is frequently cited as an early example of a major platform formally acknowledging responsibility for harm caused by user-driven misinformation.
Third-party app developer (Apollo)
Christian Selig is a Canadian iOS developer who created and maintained Apollo, a popular third-party Reddit client, from its 2015 beta until 2023. In April 2023, Reddit announced new API pricing, and Selig calculated that operating Apollo under the new terms would cost roughly US$20 million per year, which he deemed financially untenable. His public disclosure of that figure helped trigger a platform-wide protest in which thousands of subreddits went dark, and he announced Apollo would shut down on June 30, 2023. Reddit CEO Steve Huffman publicly criticized Selig during an AMA, citing Selig's release of a recorded private phone call, while Selig defended his conduct. He became one of the central figures in the 2023 Reddit API dispute.
Creator of AutoModerator; former Reddit employee
Reddit, Inc.
Chad Birch, known on Reddit as Deimorz, was a volunteer moderator of the r/gaming subreddit who in early 2012 built AutoModerator, a bot using Reddit's API to automate repetitive moderation tasks such as keyword and domain filtering. The tool became widely adopted across subreddits, and in 2013 Reddit hired Birch, who developed a wiki-based per-subreddit configuration system; AutoModerator was officially integrated platform-wide in March 2015. AutoModerator is now regarded as foundational infrastructure for content moderation on Reddit and has been the subject of academic study. Birch left Reddit in 2016.
Creator of Reddit Enhancement Suite
Steve Sobel, who uses the handle honestbleeps, is the creator and principal maintainer of Reddit Enhancement Suite (RES), a widely used browser extension that adds features and quality-of-life improvements to the Reddit website. The project began as a set of userscripts and grew into one of the most-installed Reddit extensions across Chrome and Firefox. Sobel describes himself as a long-time full-stack engineer based in Chicago who developed RES in his spare time, and the project is open source and hosted on GitHub. He is not associated with any Reddit moderation controversy; his notability is as a builder of community tooling.
Third-party Reddit app developers (2023 shutdowns)
When Reddit announced new API pricing in 2023, several long-running third-party mobile clients shut down because the costs were unaffordable. Reddit is Fun (rif), a popular Android client, shut down on June 30, 2023; its developer stated the API costs would mirror those facing Apollo despite the app generating far less revenue. Sync for Reddit also shut down on June 30, 2023, ending its Android and iOS versions, and BaconReader was likewise affected. Relay for Reddit avoided immediate shutdown by transitioning to a subscription model to cover API costs. The individual developers are generally not prominently named in mainstream coverage, which framed the story around the apps rather than named individuals.
Individual investor, r/wallstreetbets
Keith Gill is an American individual investor who became prominent on Reddit's r/wallstreetbets under the handle DeepF***ingValue and on YouTube and X as Roaring Kitty. Beginning in 2019, he posted detailed bullish analyses and screenshots of his large GameStop position, arguing the stock was undervalued. His posts were widely cited as a driving factor in the GameStop short squeeze of January 2021, which caused dramatic price swings and significant losses for short-selling hedge funds. On February 18, 2021, he testified before the U.S. House Financial Services Committee, stating he did not solicit others to trade for his own profit. Regulatory scrutiny followed: his former employer MassMutual was fined for failing to supervise his online activity, though no finding of market manipulation against him resulted.
Y Combinator first-batch founder; Reddit-era contemporary
Twitch / Y Combinator
Emmett Shear is a technology entrepreneur best known as a co-founder and longtime CEO of the live-streaming platform Twitch (originally Justin.tv). He was part of Y Combinator's inaugural 2005 batch alongside Reddit's founders, placing him within the same early startup cohort that shaped Reddit's origins. He later became a part-time YC partner advising new startups, and in November 2023 served briefly as interim CEO of OpenAI during that company's leadership crisis. His direct, documented role in Reddit's corporate governance is limited, but he is frequently cited as a peer and contemporary of Reddit's founding circle.
Early Reddit investor
Andreessen Horowitz
Marc Andreessen is a co-founder of Netscape and of the venture capital firm Andreessen Horowitz (a16z), and was among the prominent investors in Reddit. He participated in early funding for the company alongside other Silicon Valley figures, and a16z took part in later rounds including Reddit's 2019 financing. His involvement reflects Reddit's deep ties to the elite venture-capital ecosystem that funded its expansion ahead of its 2024 IPO.
Early Reddit investor
Founders Fund
Peter Thiel is a co-founder of PayPal, an early investor in Facebook, and founder of the venture firm Founders Fund, and was among the early backers of Reddit. He invested in Reddit's funding rounds during the company's formative years, joining a group of high-profile Silicon Valley investors. His participation underscores the prominent venture-capital support behind Reddit in the period after its 2006 acquisition and subsequent spin-off.
Former owner of Reddit (2006–2011)
Advance Publications
Condé Nast is the American mass-media company, owned by Advance Publications, that acquired Reddit on October 31, 2006 for a reported sum in the range of $10–20 million, a few years after the site's 2005 founding. Under Condé Nast's ownership Reddit operated as a subsidiary before being spun off as an independent operating unit of parent company Advance Publications in September 2011. The arrangement left Advance as Reddit's largest shareholder for years afterward, a stake that produced a windfall reportedly worth well over a billion dollars when Reddit went public in 2024.
Parent company & largest Reddit shareholder
Newhouse family
Advance Publications is the privately held American media conglomerate controlled by the Newhouse family that owns Condé Nast and, through it, became the controlling owner of Reddit after the 2006 acquisition. When Reddit was spun out of Condé Nast in 2011, Advance retained the largest ownership position in the now-independent company. The firm traces its roots to Samuel I. Newhouse, who built it from distressed newspaper assets beginning in the 1920s. Advance's long-held Reddit stake delivered a reported windfall of roughly $1.4–2 billion when Reddit completed its IPO in March 2024.
Investor in Reddit (2019)
Tencent Holdings
Tencent is the Chinese technology and entertainment conglomerate that, in February 2019, invested a reported $150 million as the lead in Reddit's roughly $300 million Series D financing, which valued Reddit at about $3 billion. The investment drew controversy on Reddit itself, where users objected to backing from a company associated with Chinese internet censorship; many posted images banned in China, such as the 'Tank Man' photo from the 1989 Tiananmen Square crackdown and Winnie the Pooh memes, in protest. The round also included established Reddit investors such as Sequoia, Fidelity, and Andreessen Horowitz.
Founder of r/wallstreetbets
Jaime Rogozinski founded the r/wallstreetbets subreddit on January 31, 2012, as a forum for discussing high-risk trading strategies. In April 2020, Reddit's administrators removed him as moderator, citing his attempt to trademark the community's name as a violation of policies against monetizing or claiming ownership of a community. In February 2023 he sued Reddit, alleging breach of contract and trademark infringement, but the suit was dismissed; the U.S. Court of Appeals for the Ninth Circuit affirmed the dismissal in June 2025, holding he could not establish trademark ownership because Reddit, not Rogozinski, first used the mark in commerce. The subreddit he created grew into one of the most influential trading communities and was central to the 2021 GameStop event.
Former Reddit moderator
Michael Brutsch was a prolific Reddit moderator from Arlington, Texas, who used the username Violentacrez and moderated dozens of controversial subreddits, including r/Jailbait and r/CreepShots, which hosted sexualized images of women and, in some cases, minors posted without consent. On October 12, 2012, Gawker journalist Adrian Chen published an exposé identifying Brutsch as the person behind the account. The article prompted intense debate over online anonymity, privacy, and doxxing, and some moderators banned Gawker links from their subreddits in retaliation. Brutsch was fired by his employer within roughly a day of the article's publication and later appeared on CNN's Anderson Cooper 360 expressing regret about his activities.
Science communicator banned for vote manipulation
Ben Eisenkop, an American ecologist, became one of Reddit's most beloved users under the handle Unidan, known as 'the excited biologist' for enthusiastic answers about biology and ecology, accumulating over two million comment karma. In July 2014, Reddit administrators shadowbanned him for vote manipulation after finding he had used at least five alternate accounts to upvote his own content and downvote users he argued with. The ban came to light during a heated dispute over whether jackdaws belong to the crow family. Using a new account, he publicly apologized, calling the manipulation a stupid and unnecessary move given his existing popularity.
Reddit power-user and moderator
Robert Allam, known on Reddit as GallowBoob, became one of the platform's most prominent users, accumulating tens of millions of karma points and moderating dozens of subreddits including r/oddlysatisfying. He drew recurring criticism over alleged karma-farming through tactical reposting and over a 2019 incident involving a posted Netflix logo animation, which prompted disputed accusations that he was being paid to advertise. In March 2020, a viral discussion highlighting that a small number of moderators controlled a large share of top subreddits, with Allam a focal point, triggered a wave of harassment. Allam said he received death threats and hacking attempts and stepped back from the platform.
Briefly a Reddit administrator (2021)
Aimee Challenor (later Aimee Knight) is a British transgender political activist and former politician who was hired as a Reddit administrator in early 2021. In March 2021, after a moderator was suspended for linking an article that mentioned her, large numbers of subreddits went private in protest, objecting both to the suspension and to Reddit's failure to adequately vet her background before hiring. Reddit's CEO attributed the suspension to an overly broad automated moderation rule and announced that Challenor was no longer employed by the company; nearly 600 subreddits participated in the blackout at its peak. Concerns raised by users related to her father, who was convicted in 2018 of serious crimes against a child while serving as her election agent. Challenor herself has not been accused of any crime; the controversy centered on Reddit's vetting and moderation decisions.
Actor; subject of a notorious AMA
Woody Harrelson is an American actor who held a Reddit Ask Me Anything on r/IAmA on February 3, 2012, while promoting his film Rampart. The session is widely cited as one of Reddit's worst celebrity AMAs because Harrelson repeatedly steered questions back to the film, telling participants to focus on the movie, rather than answering broadly as the format implies. Redditors criticized it as a transparent promotional exercise, and the event became a long-running cautionary example of how not to run an AMA. It is frequently referenced in later discussion of celebrity public-relations misuse of the platform.
Astronaut; acclaimed AMA from orbit
Canadian Space Agency
Chris Hadfield is a Canadian astronaut who, on February 17, 2013, conducted a Reddit Ask Me Anything from aboard the International Space Station while serving as commander of Expedition 35. The session was relayed via satellite to a ground server, making it a rare AMA hosted directly from orbit. Hadfield answered a wide range of questions about daily life in space, and the AMA was widely praised as one of the best in Reddit's history. The event contributed to his broader reputation for popular public outreach about spaceflight and stands as a frequently cited positive example of the AMA format.
Student wrongly accused in the Boston Marathon misidentification
Sunil Tripathi was a 22-year-old Brown University undergraduate who went missing in March 2013 after taking leave from his studies. Following the April 15, 2013 Boston Marathon bombing, users on the Reddit forum r/findbostonbombers attempted to crowdsource the identification of suspects, and a post wrongly named Tripathi as a possible match to released images, despite a subreddit rule against naming people without evidence. The false claim spread to other social media and was amplified by some commentators before the FBI identified the actual perpetrators; Tripathi had no connection whatsoever to the bombing. His body was recovered from the Seekonk River later that month, and authorities determined he had died before the bombing took place. The episode caused significant distress to his family and is widely cited as a cautionary case about online misidentification.
