John Hwang, CEO / Founder at Rainier Arms, LLC, built a business portfolio that includes Rainier Arms, Defense Marketing Group, a real estate portfolio across the US and Colombia, and a manufacturing company doing $10 million a year. But his path started with a family teriyaki restaurant, a failed Subway franchise, and $100,000 in debt at age 27.
In this episode of E-Coffee with Experts, host Austin Willman talks with John about rebuilding from zero, why he believes partnerships outperform solo ventures, and how he uses SBA loans and creative financing to buy businesses instead of starting from scratch. John breaks down his framework for replacing himself as an operator, why character matters more than experience when choosing a partner, and how he evaluates new industries without being an expert in any of them.
John also shares how he uses AI to speed up real estate research and contract review, and offers direct advice for mid-career professionals who feel stuck but aren’t ready to gamble on starting something entirely new.
