Career
Kim founded Nexon in 1994, while pursuing a doctorate in computer science and engineering at KAIST.[4] Under Kim's leadership, Nexon launched the world's first graphic massively multiplayer online role-playing game (MMORPG), Nexus: The Kingdom of the Winds and released popular titles such as MapleStory, KartRider, Mabinogi and Dungeon&Fighter.[5] With offices in Korea, Japan, United States, Europe and Taiwan, Nexon services over 100 online and mobile games to over 190 countries.[6][7] In 2005, the company moved its headquarters from Seoul, South Korea to Tokyo, Japan and went public on the Tokyo Stock Exchange in 2011. Nexon is valued at over US$13 billion as of March 2019.[8]
In 2009, Kim consolidated his and his family's majority holding of Nexon by establishing NXC Corporation, where he served as CEO until July 2021.[4] He is known for acquiring firms and investing in various fields.[9] Being an avid Lego fan,[10] he purchased Bricklink in 2013, an online marketplace for Lego toys. The website was sold to The Lego Group in 2019.[11] In 2014, NXC acquired Stokke, a premium children's furniture manufacturer[12] and later purchased JetKids to join Stokke in 2018.[13] Other acquisitions include Korbit in 2017[14]
In 2014, Kim joined Collaborative Fund as a partner.[18] At the time, Collaborative's founder and managing partner Craig Shapiro welcomed Kim as a "bootstrap" business expert at the firm, as he had built Nexon into a multi-billion dollar business without taking any venture capital investment. Among other contributions, Kim was interested in helping startups expand their businesses outside the US, stating that localization efforts from an early stage can help brands reach a more global audience.[19]
In 2016, Kim was charged with suspicious stock transactions and bribery after giving South Korean prosecutor Jin Kyung-joon more than 920 million KRW (US$).[20] According to prosecutors, Kim had given Jin to purchase unlisted Nexon Korea stock in 2005, which Jin then sold for US$880000 in the following year.[21] Prosecutors also alleged Jin received from Kim for overseas trips.[22] The scandal prompted Kim to issue an apology and resign from Nexon's board of directors in July 2016.[20][22]
