Within three years, Yandex became the largest search system in Russia. [...] Yandex was incorporated as a standalone company in year 2000.

»The word “Yandex” was invented by the company’s two principal founders, Ilya Segalovich and Arkady Volozh. At that time, Ilya was experimenting with different derivatives of words that described the essence of the technology. As a result, the team invented “yandex” – with Ya standing for the Russian “I”. The full name originally stood for “Yet Another iNDEX”. Today the word Yandex has become synonymous with internet search in Russian-speaking countries. Millions of people use Yandex each day for internet search and other valuable services.« Source
