In 2004, after giving birth to her first child, Bakalchuk launched Wildberries, which initially focused on reselling apparel from Otto and Quelle catalogs.

[9] The Bell's source claims that the Bakalchuks did not initially sell clothes solely from Otto or Quelle catalogs.

In 2003, the shopping center's address was listed in the contacts of the D-Luxe catalog made by Bakalchuk's and Fadeev's UT Design studio.

[11][12] Wildberries was among the first Russian e-commerce companies to offer a flat delivery rate and free try-on and to build a network of pick-up points with fitting rooms.

[9] Moreover, in 2020, Tatyana Bakalchuk acquired Standard-Credit Bank, which Samvel Karapetyan's Tashir Holding previously controlled.

[22][28] In 2021, the Russian Ministry of Digital Development added four new categories (including e-commerce) to the list of preinstalled applications.

[29] In 2022, the Ministry of Industry and Trade publicly stated that the online market Wildberries sells counterfeit products.

[32] In April 2023, Tatyana Bakalchuk announced the search for a new Russian-language brand instead of Wildberries due to the ban on using foreign words in Russian advertising.

[33] In 2021, the government of Ukraine imposed sanctions over Tatyana and Vladislav Bakalchuk and Wildberries for selling Russian military uniforms and anti-Ukrainian literature.

[36] In December 2021, Forbes named Tatyana Bakalchuk, who owns 99 percent of the Wildberries e-commerce platform, the wealth growth dynamic leader among the world's billionaires.

[36] Until December 31, 2019, Tatyana was the sole owner, but then she transferred 1% to her husband Vladislav Bakalchuk, thus moving their family to the first place in the Forbes ranking of Russia's richest families—ahead of the Rotenbergs.

The joint ownership of the company will enable Wildberries to create subsidiaries under a simplified procedure, building the structure of a more successful corporation.

[38] In July 2024, her husband sought the help of Ramzan Kadyrov in a conflict with his wife, alleging that Wildberries' announced merger with Russ Group was detrimental for the company; later that month, she filed for divorce.

[39] In September 2024 Vladislav was arrested on a murder charge following a deadly shootout which occurred after he and other armed men raided Wildberries' Moscow headquarters.

He is a nephew of Sergei Tsoy, Rosneft vice president and former head of Yury Luzhkov's press service.
