Founder Yoon Hyuk-jin describes building food businesses including Jamjam Pasta, Jamjam Chips, and Kkeutteumeorijip. He says he began with ₩30 million saved from salaried work and deliberately avoided debt. After searching for a location for six months, he negotiated the key money down by ₩15 million and opened in a weak foot-traffic spot. He promoted before opening by greeting passersby at lunch and after work and handing out business cards with a free fries coupon. The first day brought ₩600,000 in sales. By 2019, annual sales had reportedly grown to ₩1.5 billion, before COVID disrupted the business. These figures are the founder’s account in a Korean interview.
