Bang Si-hyuk

Bang was born on August 9, 1972 to Bang Geuk-yoon, former president of the Korea Workers' Compensation and Welfare Corporation at the Korea Social Insurance Research Institute, and his wife, Choi Myung-ja. Bang has a younger sister.

Bang developed a passion for music from an early age, having grown up in a musical home, but was discouraged from pursuing a career in the industry by his parents. Bang formed a band with his friends while in middle school and wrote and performed songs he composed. He attended Kyunggi High School before graduating from Seoul National University with a degree in aesthetics.

Bang debuted as a composer while in college. In 1994, he won the Yoo Jae-ha Music Contest and began his career in earnest writing and producing songs. He met Park Jin-young in 1997, and the pair often partnered together as a songwriting duo. Bang joined JYP Entertainment, becoming a composer, arranger and producer at the company. One of their early successes was the first-generation group g.o.d. Some of g.o.d's most famous songs arranged by Bang include "One Candle" and "Road". Bang's stage name "Hitman" originated from this period, when g.o.d enjoyed success as one of the country's best-selling and most popular boy bands of the early 2000s, earning himself and Park a reputation as "hit makers". Besides g.o.d, Bang has produced or composed for many other artists, including veterans Im Chang-jung and Park Ji-yoon, singer-actor Rain, groups Wonder Girls, 2AM, and Teen Top, and R&B singer Baek Ji-young.

Nearly four years after joining JYP Entertainment, Bang left JYP and founded his own company, Big Hit Entertainment, where he continued to write, compose and produce for its artists. Under the Big Hit label, he signed up RM, at age 15, who would go on to lead the boy band BTS. He co-wrote six songs for BTS in their 2016 album Wings. Its success garnered Bang the Best Producer Award at the Mnet Asian Music Awards and the Songwriter Award at the Melon Music Awards that year. In June 2018, he was named one of Variety's International Music Leaders due to BTS' achievements.

In April 2019, Bloomberg estimated Bang's worth to be about $770 million. The BigHit initial public offering (IPO) filed in October 2020 was the largest seen in South Korea in three years and skyrocketed Bang's net worth to $2.8 billion, making him the only billionaire in South Korea's entertainment industry and the sixth-richest person in the country. The success of the IPO, together with the commercial success of BTS that year, Bang's steps into diversification with apps like Weverse, and acquisitions of companies like Source Music and Pledis Entertainment among others, landed him on the 2020 edition of Variety's Variety500, an annual index of the 500 most influential business leaders in the global media industry.

In June 2021, Forbes Asia published its annual list of Korea's 50 Richest People. One of only two newcomers to the ranking, Bang was listed as the 16th richest person in South Korea. On July 1, following an organizational restructuring, Hybe announced Bang's resignation as CEO of the company to return his focus to music production. He was replaced by Park Ji-won, but retained his position as Chairman of the Board of Directors. According to the Bloomberg Billionaires Index, Bang is worth an estimated $3.2 billion as of July 2021.

Bang was featured on the cover of the April 2022 issue of Time magazine, together with BTS, following the release of the outlet's annual list of the 100 Most Influential Companies in March. Later that month, he received an honorary doctorate in Business from Seoul National University—he is the first figure in the entertainment industry to be awarded such—in recognition of his "contribution to the development and innovation of the nation's cultural and entertainment industry" and for his "role in turning K-pop into a global pop music culture".

In October 2022, Bang donated ₩5 billion (US$4.37 million) to the Community Chest of Korea. On February 17, 2023, Bang donated 200 million won through Save the Children to help in the 2023 Turkey–Syria earthquakes. In March 2025, Bang donated ₩5 billion (US$4.37 million) to Seoul National University for the construction of a new Cultural Center.

Loan to Min Hee-jin towards her share in ADOR

In October 2026, it was reported that Bang had filed a civil lawsuit against Min Hee-jin seeking repayment of approximately ₩4.21 billion (US$3.68 million), including interest, from a loan made in connection with her purchase of ADOR shares in 2023. According to media reports, Min borrowed ₩3.74 billion (US$3.27 million) from Bang when she purchased 573,160 shares in ADOR, representing approximately 17.8% of the company, for about ₩3.738 billion.

Bang reportedly applied for a payment order in April 2026, and the Seoul Western District Court issued an order in May requiring Min to repay the whole amount plus interest. Min contested the order in July, resulting in the matter proceeding as a civil lawsuit. The claimed amount included approximately ₩500 million (US$437,082.04) in interest, although the precise terms of the loan agreement were not publicly confirmed.

Min's representatives disputed the separate pursuit of repayment, arguing that the loan was connected to the shareholder agreement between the parties and should be offset against amounts payable under a separate put-option dispute. They cited a first-instance ruling ordering Hybe to pay Min approximately ₩25.5 billion (US$22.29 million) in connection with the put option. Hybe appealed that ruling, leaving the dispute unresolved at the time of the October 2026 reports. Min's representatives characterized the repayment lawsuit as inconsistent with Hybe's failure to pay the put-option amount pending appeal and stated that Min intended to resolve the parties' financial claims through the legal proceedings.
