Bang Si-hyuk

In April 2019, Bloomberg estimated Bang's worth to be about $770 million.

In 2005, Bang left JYP Entertainment and founded his own company Big Hit Entertainment, which later became home to boy bands BTS and TXT. He continues to write, compose and produce, and most recently co-wrote six songs in BTS' critically acclaimed album Wings, released in October 2016. The success of Wings garnered him 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 International Music Leaders by Variety due to BTS' achievements.

Bang debuted as a composer while in college. He met Park Jin-young during the mid-1990s, and the pair often partnered together as a songwriting duo. When Park founded his company JYP Entertainment, Bang joined him as a composer, arranger and producer. One of their early successes was the first-generation group g.o.d. They were largely responsible for the production of g.o.d's debut album Chapter 1, with Park serving as the producer and primary songwriter while Bang arranged the instrumentation and music. Some of g.o.d's most famous songs whose soundtrack was arranged by Bang include "One Candle" and "Road". His 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 the reputation as "hit makers". Besides g.o.d, Bang has also produced or composed for artists such as veterans Im Chang-jung and Park Ji-yoon, singer-actor Rain, groups Wonder Girls, 2AM and Teen Top, R&B singer Baek Ji-young and many others.
