Isaac Toast is making strides in the international market with its "Korean-style toast."
Founded in 1995 as a small personal store, Isaac Toast began franchising in 2004. Last year, the company sold 50 million toasts, generating approximately 243.7 billion won in brand revenue for 2025. Currently, it operates over 900 stores nationwide.
The brand's competitive edge lies in its freshly baked bread topped with eggs, ham, vegetables, and a sweet signature sauce. The company has packaged this sauce in 260-gram bottles, launching it as its first overseas-exclusive product this year. To protect domestic franchisees, the sauce is not sold through regular domestic distribution channels but is available at duty-free shops and in international markets.
The signature sauce has been sold since April at Incheon International Airport's Terminal 1, with sales expanding to online malls and the Myeongdong store, as well as Terminal 2. In July, it reached the top of all categories on the Shinsegae Duty-Free online mall. From April to August, donations linked to sauce sales totaled 9,502,500 won, indicating an estimated sales volume of 95,025 bottles based on a 100 won donation per bottle sold.
Isaac Toast has also broadened its engagement with international consumers. Starting in May with KCON Japan, the company held pop-up events in Tokyo and Osaka, featuring local media appearances with brand model Mingyu from Seventeen. In September, it opened a pop-up in Omotesando, Tokyo, and confirmed international consumer demand by selling the signature sauce at Shinsegae Duty-Free.
The company is expanding its product offerings. Following the signature sauce, it has introduced four types of fruit jams—kiwi, apple, peach, and strawberry—broadening its business scope from toast shops to food distribution. The goal is to develop the sauce and jams into versatile products that can be used with various items like bread and crackers, thereby expanding the Isaac Toast brand in the international retail market.
