ByteDance

• 1. Introduction

  ›

  ByteDance is a Chinese internet technology company headquartered in Haidian, Beijing. Its story begins in early 2012, when two friends rented an apartment in Zhongguancun and put a handful of former colleagues to work on a new app. By November 2024, the company that grew out of that apartment was estimated to be worth 300 billion dollars. It is the developer behind TikTok and its Chinese counterpart Douyin, along with the video editor CapCut and the app Lemon8. Oddly, the company people talk about as Chinese has a legal twin: its associated variable-interest entity, ByteDance Ltd, is incorporated in the Cayman Islands. That detail hints at a larger puzzle. How did a small team in a rented flat build an empire of apps used far beyond China? Who actually owns it, and who answers to whom inside it? And why have governments in Beijing, New Delhi, Washington and elsewhere all taken a hard look at it?

  ›

  In 2009, Zhang Yiming and his friend Liang Rubo co-founded 99fang.com, a real estate search engine. Three years later, they and several colleagues from that site started building software that used big data algorithms to sort news by each reader's tastes. In March 2012, Zhang and Liang formally founded ByteDance.

  The company's first release came that same month. Neihan Duanzi, whose Chinese name means roughly "profound gags", let users pass around jokes, memes and funny videos. In August 2012, ByteDance launched Toutiao, a name meaning "headlines". It began as a news recommendation engine and gradually widened into a platform for text, images, question-and-answer posts, microblogs and video. It would become the company's core product.

  In January 2013, executives were shown a four-part plan for the future, framed around both commercial and nationalist goals. Its fourth part called for an English version of Toutiao, aimed at users in English-speaking countries. The plan arrived while apps were racing each other for video views and for the attention of phone users.

  In January 2014, the company opened Toutiaohao, a platform built to draw in content creators. Video features arrived later that year. Toutiao relied on interest-based, decentralized distribution, which helped creators with small, specialized audiences find readers. The next move was to take the same recommendation machinery into short video.

• 3. The Road to TikTok

  ›

  In September 2016, ByteDance released Douyin, which had been called A.me in its early days. It is the short-video app for the Chinese market. A year later, in September 2017, TikTok appeared as a video-sharing service for dance, comedy, education and other short clips.

  Around these releases, the company went shopping. In December 2016, it invested in BABE, an Indonesian news recommendation platform. In February 2017, it bought Flipagram, which was rebranded as Vigo Video, also called Hypstar, that July. Vigo Video was shut down for good on the 31st of October 2020.

  The biggest purchase came in November 2017, when ByteDance acquired musical.ly for an estimated one billion US dollars. The source notes that TikTok was then available only in India, while musical.ly was available worldwide. To take TikTok global, ByteDance merged musical.ly into it on the 2nd of August 2018, and kept the TikTok name. That same month in 2017, it also bought News Republic from Cheetah Mobile.

  Douyin and TikTok look almost identical, yet they are walled off from each other. Users of one cannot see the other's videos, and each runs on servers in the market where it is offered. Douyin also carries more features than its international sibling.

  CapCut reached the public in April 2020 as a video editor made for beginners. By March 2023, it had more than 200 million active users each month. The Wall Street Journal reported that it was downloaded more often than TikTok itself that month. In the United States, only the app of the discount retailer Temu was downloaded more.

  Lark, released in 2019, began life as a tool for ByteDance's own staff. It became the company's main internal platform for communication and collaboration, and later opened to outside users in some markets. Xigua Video, first launched as Toutiao Video in 2016, hosts user-made short and mid-length clips and also produces film and television. In April 2021, a new division called BytePlus began offering the software framework behind TikTok so others could build similar apps. That August, ByteDance bought Pico, a virtual reality startup compared to Oculus.

  Nuverse, a game publisher launched in 2019, released Warhammer 40,000: Lost Crusade outside mainland China in 2021. Later that year, it took on Moonton, maker of the mobile esports game Mobile Legends: Bang Bang, after winning a bid first set by Tencent. In October 2022, Nuverse launched Marvel Snap worldwide. Still, in November 2023, Reuters reported that ByteDance was restructuring Nuverse and retreating from gaming.

  Former employees described an internal practice called "horse racing", reported by The Wall Street Journal in March 2023. Several teams are assigned to build the same product, and the team with the better version gets more support. The Financial Times had reported a culture clash at the London office in June 2022 that led to a staff exodus. In May 2024, the company laid off a large share of about 1,000 employees across global user operations, content and marketing teams.

  Many experiments ended quickly. Gogokid, launched in May 2018 for one-on-one English lessons for children, was closed in August 2021 after new rules hit after-school tutoring in China. TopBuzz, started in 2015 as a hub for videos, articles and GIFs, was abandoned in 2020. Former employees alleged it pushed soft messaging sympathetic to China abroad, which ByteDance denied. TikTok Music, formerly Resso, launched in Indonesia and Brazil in July 2023, but ByteDance announced on the 24th of September 2024 that it would close on the 28th of November. The publisher 8th Note Press, set up in 2023, shut abruptly in June 2025 and returned publishing rights to its authors. LetsChat, a low-data messaging app marketed mainly in Africa, drew 7 million downloads, mostly in Nigeria, before it was discontinued in March 2024.

• 5. The AI Push

  ›

  In March 2016, ByteDance created its research arm, the ByteDance AI Lab, headed by Wei-Ying Ma, formerly assistant managing director of Microsoft Research Asia. Seven years later, in 2023, it formed an AI team called Seed. Its chatbot app Doubao launched in August 2023.

  In December 2023, The Verge reported that ByteDance had used OpenAI's API in its own generative AI projects. OpenAI said the usage was minimal but suspended the account while it investigated possible violations of its terms of service. ByteDance replied that it held a licence to use the API outside China, that its chatbot is offered only inside China, and that ChatGPT-generated data had been deleted from its training data since the middle of 2023. Scraping existing AI models is a common shortcut for smaller companies but is considered unusual for a firm of ByteDance's size.

  The model family has since multiplied. Seed is a proprietary large language model, while seed-oss is open-source, and both are available in the United States. Seedream creates and edits images from text. Seedance turns text or images into video. In September 2024, ByteDance's cloud arm Volcano Engine, founded in 2021, introduced its own AI video generator. In February 2025, the company showed OmniHuman-1, a system that builds realistic video from one image plus motion signals such as audio or a video clip. It is not open to the public.

  The 1st of December 2025 brought an AI voice assistant for Chinese smartphones, debuting on ZTE's Nubia M153 and powered by Doubao. In February 2026, ByteDance released Seedance 2.0, which the U.S. Motion Picture Association denounced for copyright infringement. On the 12th of March 2026, the company disclosed a plan with Aolani Cloud to deploy about 500 Nvidia Blackwell systems in Malaysia, totalling roughly 36,000 B200 chips.

  A list of ByteDance's backers reads like a map of global finance: Jeff Yass's Susquehanna International Group, Primavera Capital Group, Kohlberg Kravis Roberts, SoftBank Group, Sequoia Capital, General Atlantic and Hillhouse Capital Group. Investors outside China hold 60 percent of the company. Its founders and Chinese investors hold 20 percent, and employees hold the remaining 20 percent.

  In 2021, the state-owned China Internet Investment Fund bought a 1 percent stake in the main Chinese subsidiary, Beijing ByteDance Technology, a so-called golden share. It also seated Wu Shugang on that subsidiary's board, a government official with a background in propaganda. In 2023, G42 bought a stake in ByteDance itself.

  Zhang Yiming served as chairman and CEO from 2012 until 2021, when co-founder Liang Rubo took over as CEO. On the 19th of May 2020, ByteDance and Disney announced that Kevin Mayer, head of Disney's streaming business, would join. He ran TikTok as CEO and served as ByteDance COO from June 2020 until he resigned on the 26th of August 2020. In 2021, Shou Zi Chew, formerly CFO of Xiaomi, became TikTok's CEO.

  As of November 2024, the board held five directors: Liang Rubo, Arthur Dantchik of Susquehanna International, William E. Ford of General Atlantic, the French businessman Xavier Niel, and Neil Shen of HongShan. Ownership is still moving. On the 16th of April 2026, it emerged that the British tech investor Fred Blackford had built a stake worth more than 50 million dollars.

• 7. The Party at the Table

  ›

  In 2014, ByteDance set up an internal Chinese Communist Party committee. Its secretary is vice president Zhang Fuping. According to a report given to the Australian Parliament, he said ByteDance should "transmit the correct political direction, public opinion guidance and value orientation into every business and product line."

  The sharpest lesson in state power came in April 2018. China's National Radio and Television Administration ordered Toutiao and Neihan Duanzi removed from app stores for a time. It accused Neihan Duanzi of hosting "vulgar" and "improper" content. The next day, the joke app announced it was closing permanently, despite having more than 200 million users. Zhang Yiming wrote that the app was "incommensurate with socialist core values" and promised to "further deepen cooperation" with the authorities. ByteDance then said it would favor Communist Party members in hiring and raise its censors from 6,000 to 10,000.

  The ties run through partnerships too. ByteDance has a strategic partnership with the Ministry of Public Security covering the ministry's public relations, plus unspecified "offline activities". In 2018, it helped found the Beijing Academy of Artificial Intelligence, backed by the Ministry of Science and Technology and the Beijing municipal government. In 2019, it formed joint ventures with Beijing Time, a publisher controlled by the Beijing municipal party committee, and with Shanghai Dongfang, a state media firm. The Shanghai Dongfang venture was announced in 2021 as having never operated. In June 2022, it teamed with Shanghai United Media Group on a plan to develop influencers.

  Regulators kept coming. Since 2019, the Beijing headquarters has hosted an office where cybersecurity police are stationed so illegal content can be reported instantly. In November 2019, the Cyberspace Administration of China ordered "slanderous" material about Fang Zhimin removed from Toutiao. In April 2020, it ordered Lark taken down because it could help users get around censorship. In January 2021, regulators fined ByteDance for spreading "vulgar information". In April 2021, the People's Bank of China was among those telling 13 platforms to tighten data and financial compliance. In May 2021, the Cyberspace Administration said ByteDance had illegally collected and misused personal information. In March 2021, a subsidiary was fined for antitrust violations.

  Censorship demands grew more political. In April 2022, ByteDance said it would report Toutiao and Douyin users engaged in "historical nihilism" against the official party version of history. In November 2022, as protests over COVID-19 restrictions spread, the Cyberspace Administration directed the company to intensify censorship of them. In November 2023, Forbes reported that authorities had accessed Feishu, the internal workplace tool, before the 20th National Congress of the party. In September 2025, a crackdown on Toutiao cited content promoting "negative outlooks on life such as world-weariness."

  ›

  On the 29th of June 2020, India banned TikTok and CapCut along with 58 other Chinese apps, citing national security. The ban was made permanent in January 2021. In March 2021, India froze ByteDance's local bank accounts over alleged tax evasion, which the company disputed.

  Elsewhere, the questions were about money and structure. In 2022, Turkey's Financial Crimes Investigation Board opened a probe into fund transfers worth millions of dollars involving TikTok accounts suspected of money laundering or terrorism financing. In December 2022, Taiwan's Mainland Affairs Council began investigating whether ByteDance ran an illegal subsidiary. A firm named Tiktoktaiwan Co Ltd was registered in March and renamed ByteDance Taiwan in November. In 2023, the Central Bank of Ireland scrutinized weaknesses in the anti-money laundering controls of ByteDance's payment division.

  The most sustained fight has been in the United States. In 2019, the Federal Trade Commission fined TikTok for violating the Children's Online Privacy Protection Act, and TikTok added a kids-only mode. In August 2024, the FTC and Department of Justice sued, alleging violations of the 2019 consent decree. In September 2024, an FTC report on nine companies, ByteDance among them, found data practices exposing people to identity theft, stalking and other harms. In March 2023, an investigation began after ByteDance employees tracked journalists to find leaks, and the company fired four employees.

  Lawmakers feared surveillance by the Chinese government. President Trump wanted TikTok sold or barred from app stores, but courts blocked his executive orders and President Biden revoked them. On the 28th of August 2020, China updated its export control rules in a way experts said could give Beijing a say over any sale of ByteDance technology to foreign firms.

  ByteDance fought back through lobbying. Disclosures show it approached Congress, the White House and the Departments of Commerce, State and Defense. Its American team is led by Michael Beckerman and includes former senators Trent Lott and John Breaux, and former representatives Jeff Denham, Bart Gordon and Joe Crowley. It spent more than 17.7 million dollars from 2019 to July 2023, including 8.7 million in 2023. In March 2024, it spent 2.1 million dollars on its own campaign in swing states with vulnerable Senate Democrats.

  That same month, the House passed a divestiture bill. A modified version cleared Congress in a foreign aid package, and President Biden signed it on the 24th of April 2024. It gave ByteDance until the 19th of January 2025 to sell TikTok. In November 2024, Donald Trump spoke against a ban, after ByteDance investor Jeff Yass had donated to his campaign. On the 18th of January 2025, four more ByteDance apps were banned: CapCut, Lemon8, Gauth and Hypic. Marvel Snap also lost service, which was restored from the 21st of January after the delay to enforcement of the law, and the game returned to the App Store on the 27th.
