Brian Jung, who publishes as "Jungernaut," is an American YouTuber from Silver Spring, Maryland, who turned personal-finance education into a media business. Raised in a low-income Korean-American household, he earned an associate's degree from Montgomery College and dropped out before a planned transfer to build his channel full time, which he started in 2018.

Jung grew past 2.1 million subscribers by simplifying credit-card strategy, everyday personal finance and approachable crypto and investing content for a young audience. By his mid-twenties his business was reportedly generating over $300,000 a month across affiliate marketing, memberships and sponsorships, with a widely reported year near $3.7 million. He is less a trader than a finance educator and operator, but his scale and crossover into crypto make him a notable name in the broader money-content space.
