Yandex LLC is a Russian technology company that provides Internet-related products and services including a web browser, search engine, cloud computing, web mapping, online food ordering, streaming media, online shopping, and a ridesharing company.
Yandex Search is the largest search engine in Russia with an estimated 72% market share in Russia[4] and a 2.8% market share worldwide.[5] Yandex Taxi is the largest ridesharing company in Russia.[6]
Yandex was founded by Arkady Volozh and launched its first product, a search engine, in 1997. Due to its significant media activities in Russia, the company has long faced pressure for control by the government of Russia. In July 2024, in a transaction brought about by international sanctions during the Russian invasion of Ukraine and restrictions on foreign ownership, Nebius Group, the Dutch holding company that owned Yandex, sold its Russian assets to a group of Russian investors for a discounted price of US$5.3 billion.
History
1990s
In 1990, Arkady Volozh contacted Ilya Segalovich (1964–2013), a friend of his from high school, to join his venture developing algorithms to search Russian texts.[7] They developed search software together under the company name Arcadia.[8] In 1993, they invented the name "Yandex" as an easy way to remember "Yet Another iNDEXer".[9] This is also a bilingual pun on "index" since "Я" ("ya") means "I" in Russian.
On September 23, 1997, the Yandex.ru search engine was launched and presented at the Softool exhibition in Moscow.[10] In 1998, Yandex launched contextual advertisement
Open source
In 2009, Yandex began development on its project MatrixNet. It was a unique, patented algorithm for building machine learning models, which utilized one of the original gradient boosting schemes. In July 2017, the CatBoost library was released to the public. It implements the MatrixNet algorithm for building machine learning models.[154]
At the time of release, the technology was already in use as part of a collaborative project with the European Organization for Nuclear Research (CERN) to analyze the results of particle experiments conducted.[155]
CatBoost is used by JetBrains for code completion, CloudFlare for bot detection, and Careem for trip-distance determination.[156][157]
Data breaches
Cyberattack (October / November 2018)
In October and November 2018, Yandex was targeted in a cyberattack using the Regin malware, aimed at stealing technical information from its research and development unit on how users were authenticated.[165] An investigation by Kaspersky Lab attributed the hacks to Five Eyes intelligence agencies.[165]
Compromise of email accounts of 5,000 users (February 2021)
In February 2021, Yandex admitted that one of its system administrators with access rights to Yandex's email service had enabled unauthorized access, leading to almost 5,000 Yandex email inboxes being compromised.[166] The company sent an apology by email to the owners of the compromised mailboxes, but no compensation was announced.
Legal issues
Legal issues in Ukraine
In May 2017, Yandex was banned in Ukraine by Presidential Decree No. 133/2017.[170] On June 1, 2017, Yandex closed its offices in Kyiv and Odesa after the Security Service of Ukraine raided the offices and accused the company of illegally collecting Ukrainian users' data and sending it to Russian security agencies.[171] The firm denied any wrongdoing.
In June 2022, after the Russian invasion of Ukraine, the company no longer displayed any national borders on Yandex Maps.[172][173]

In popular culture
In April 2014, a film about the history of Yandex called Startup was released.[190][191] The film was compared to The Social Network.[190]
