Last reviewed: 2026 · By Swet Parvadiya
Background
Jae-won Lee was a pioneering internet entrepreneur who founded the search portal Daum, establishing the foundational advertising and web infrastructure that would eventually merge with Kakao to create the modern digital conglomerate. His defining founding philosophy was a deep belief in the power of open internet search and community portals, establishing the technical architecture and operational standards that allowed Daum to become the mandatory digital gateway for the South Korean internet economy.
Founding Story
Jae-won Lee founded Daum in 1999, serving as the company’s initial technical architect and leading the development of the first practical search engine and community portal in South Korea. Under his leadership, Daum established the technical standards for internet search, email services, and cafe communities that became the industry benchmark for the rapidly modernizing South Korean digital infrastructure. Lee instilled a culture of extreme technical excellence and operational rigor, making Daum the preferred digital gateway for the South Korean government and the nation’s largest internet users. He led the company’s early engineering teams through the brutal dot-com crash of the early 2000s, ensuring that the digital infrastructure remained operational and secure even as the company faced massive financial restructuring. In 2014, Daum formally merged with Kakao to form Daum Kakao, but Lee’s legacy is a company that proved that advanced internet search and community portals were the mandatory foundations for the South Korean digital economy, a philosophy that remains the core tenet of Kakao’s platform and advertising strategy today.
