The Gentle Monster: How an English Teacher Built a Billion-Dollar Eyewear Empire

The Gentle Monster: How an English Teacher Built a Billion-Dollar Eyewear Empire A story of how one man’s vision transformed a pair of glasses into a global cultural phenomenon. The boat appeared to be crashing through the building. Passersby in Seoul’s Nonhyeon district stopped and stared, unsure whether they were witnessing an accident or a work of art. It was 2013, and this was the opening of Gentle Monster’s first showroom—a statement so bold, so audacious, that it announced to the world that a new kind of eyewear company had arrived. This was not a store. It was a declaration of war against everything the industry had ever known. The man behind this spectacle was Hankook Kim, a 30-something entrepreneur with no background in fashion, no experience in retail, and no connections in the eyewear industry. Just two years earlier, he had been running an English summer camp for children in Seoul. Now he was betting everything on a simple but radical idea: that a pair of glasses could be more than a medical necessity or a fashion accessory. It could be a work of art. The story of Gentle Monster begins not in a design studio or a fashion house, but in an education company. In 2011, Hankook Kim was working at an English-education firm when an internal competition was announced: pitch a new business idea, and the company might fund it. Kim’s proposal was unusual. He wanted to sell eyewear. The Korean eyewear market at the time was dominated by a traditional supplier-to-optician model. Glasses were functional, clinical, and largely forgettable. The designs that did exist were overwhelmingly Euro-centric, created for Western faces and Western tastes. Kim saw a gap. “In Korea, having a small face is the biggest compliment,” he would later explain. “There were no competitors for oversize glasses, which make heads look smaller.” The initial seed capital was modest—just 50 million Korean won, roughly $45,000. But Kim’s pitch attracted the attention of Jae Wook Oh, the CEO of the education company, who became the largest shareholder and provided an additional $100,000 in 2012 to kickstart production. Kim used the money to purchase factories in both Korea and China, a move that would prove crucial. “By owning the factory, we can maintain high quality at a cheaper price and control the shipping,” Kim explained. From day one, Gentle Monster would control its own destiny. The name itself was a statement of intent. “Gentle” represented the wearability and comfort of the glasses—frames that would sit easily on Asian faces, that would feel natural and effortless. “Monster” embodied something else entirely: the brand’s edgy, avant-garde, convention-defying spirit. As Kim would later reflect, “The paradoxical nature of the brand name reflects the brand’s values. As all humans do in nature, there exists a certain duality within me: the gentle and the monster.” The boat crashing through the building was just the beginning. After the success of the Nonhyeon showroom, Kim launched what he called the “Quantum Project”—a commitment to completely redesign the store’s installation every 25 days. It was an absurd idea by any conventional retail standard. Why spend money constantly rebuilding a store? Why not just find a design that works and stick with it? But Kim understood something that his competitors did not. “Retail is driven by human’s curiosity,” he would say. In an age of e-commerce, when anyone could buy anything online, the physical store had to offer something that a website never could: surprise, wonder, the thrill of discovery. Each visit to a Gentle Monster store had to feel like the first time. The themes were wildly imaginative. One store in Singapore was an interpretation of Nietzsche’s “Thus Spoke Zarathustra.” A location in Hongdae, Seoul, explored the sense of smell through artworks reminiscent of Juan Miró’s mobiles. There was a post-apocalyptic world in Chengdu, a laundromat in Daegu, a kinetic installation themed around the harvest in Los Angeles. The company began employing more spatial designers than product designers—a ratio that would have been unthinkable at any other eyewear company. Professor David Dubois of INSEAD, the business school, would later describe the effect: Gentle Monster creates “the perfect retail immersion storm” with its “eye-catching, highly instagrammable installations that make visitors feel as if they’re stepping into an art gallery.” While the innovative retail concept was generating buzz among Seoul’s fashion-forward crowd, it was a single television appearance that catapulted Gentle Monster into the mainstream. In late 2013, the wildly popular K-drama “My Love From the Star” premiered, starring Jun Ji-hyun as a haughty celebrity who falls in love with an alien. Jun’s character wore a pair of Gentle Monster sunglasses. The effect was instantaneous and overwhelming. The sunglasses sold out overnight. Orders flooded in from across Asia. Gentle Monster, which had been a cult favorite among Seoul’s creative class, was suddenly a household name. By 2016, the company was generating roughly $160 million in annual revenue. The “My Love From the Star” moment was a powerful lesson in the value of cultural marketing—and in the immense, often underestimated influence of Korean pop culture on global fashion trends. Kim had stumbled onto something bigger than eyewear. He had tapped into the rising tide of the Korean Wave, the global spread of K-pop, K-drama, and Korean beauty standards that was reshaping the fashion industry. Kim doubled down on the cultural strategy. The most significant partnership came with Jennie Kim of BLACKPINK, arguably the most influential K-pop star in the world. The “Jentle Home” collection, launched in 2020, was not just a product collaboration—it was a cultural event. The pop-up stores were designed to look like dollhouses, whimsical and fantastical, perfectly calibrated for Instagram. The “Jentle Garden” and “Jentle Salon” collections followed, each generating massive social media buzz and reinforcing Gentle Monster’s status as the eyewear brand of choice for a new generation. But Kim was careful not to limit the brand to K-pop. Gentle Monster also cultivated a long-standing relationship with Tilda Swinton, the British actress whose androgynous and avant-garde persona aligned perfectly with the brand’s aesthetic. High-fashion collaborations followed: Fendi, Moncler, Maison Margiela under the direction of John Galliano, Mugler, Heron Preston, Ambush, Coperni. Each partnership expanded the brand’s reach and reinforced its position at the intersection of fashion, art, and culture. The creative success was matched by financial performance that defied industry norms. In 2023, Gentle Monster reported 50% growth—dwarfing EssilorLuxottica’s 7% and Warby Parker’s 12%. The company’s operating margin approached 30%, nearly double that of Luxottica, the industry giant that controls brands like Ray-Ban and Oakley. The secret was the direct-to-consumer model. Early in the company’s history, Kim had approached traditional retailers about carrying Gentle Monster. He was rejected. The established players saw no reason to make room for an unknown Korean brand with oversized frames and strange marketing. It was a blessing in disguise. Forced to sell directly to consumers, Gentle Monster built a business model that gave it complete control over pricing, brand image, and customer relationships—and that captured margins that traditional wholesale arrangements would have surrendered to middlemen. Investors took notice. In 2017, L Catterton, the private equity arm of LVMH, invested $60 million, valuing the company at over $1 billion. It was a remarkable milestone for a brand that had started with $45,000 just six years earlier. Luxottica itself, the company that had once rejected Gentle Monster, became a shareholder in 2023. Then came Google. In June 2025, the tech giant invested $100 million for a 4% stake in IICOMBINED, Gentle Monster’s parent company. The partnership was aimed at developing smart glasses, putting Gentle Monster in direct competition with Meta in the emerging AR wearables market. “Creativity and sophistication are essential design features for the integration of technology into everyday life,” Gentle Monster said of the partnership. By August 2025, IICOMBINED was valued at 3.35 trillion won—approximately $2.4 billion. Today, Gentle Monster operates 81 stores across 14 countries. The company has expanded beyond eyewear, launching the cosmetics line Tamburins and the dessert brand Nudake. The “Haus” concept—massive, multi-story retail spaces that combine art, technology, and fashion—represents the next evolution of Kim’s vision. Haus Shanghai spans 35,000 square feet. Haus Dosan in Seoul integrates all of the company’s brands into a single, immersive ecosystem. Kim himself remains focused on the future. In interviews, he has spoken about his desire to take the company public—not for personal gain, but for his employees. “I want my employees to be able to buy a house,” he has said, referring to South Korea’s notoriously expensive housing market. It is a statement that reveals something about the man behind the monster: a leader who sees his success as inseparable from the people who helped build it. The story of Gentle Monster is, at its heart, a story about seeing differently. Hankook Kim looked at the eyewear industry and saw not constraints but possibilities. He looked at retail and saw not a dying channel but an untapped medium for art and storytelling. He looked at Korean culture and saw not a local phenomenon but a global force waiting to be harnessed. “There is no use lamenting what we do not have,” Kim once said. “We are building our own history in our own way. Pile up great moments, and you become a great brand.” The boat is still crashing through the building. And the world is still watching.
