Lee Su-jin is a South Korean businessman, the self-made billionaire Founder and Executive Chairman of Yanolja (KRX: 304560), a major travel technology company and the largest online accommodation booking platform in South Korea. His career is rooted in extreme poverty and entrepreneurial resilience.

Lee's early life was marked by hardship: he was orphaned at a young age and grew up in poverty. He worked his way through school and served in the military. His career began humbly, working 100-day construction jobs and later cleaning love hotels (short-stay hotels) for four years, earning a meager wage.

• Yanolja (Founder & Executive Chairman): The core publicly traded asset, the largest online accommodation booking platform in South Korea (valued at $9.6 billion in 2021).
• Startup Struggles: He started his venture after working in love hotels for four years, recognizing the structural need for modernization and digitalization of the accommodation industry.
• Technology Focus: His success is built on mobile technology and cloud-based solutions for hotels and property management.
• Personal Motto: His commitment is to changing the negative image of budget accommodation through transparency and quality standards.

Lee Su-jin's strategic genius was his commitment to digitalizing budget accommodation. He founded Yanolja (meaning 'Hey, let's play!' in Korean) in 2007, initially as an online platform to provide information and transparency about 'love hotels. He expanded the platform into a full-service travel technology company, providing cloud-based property management software for hotels globally.

His structural contribution is immense: modernizing the accommodation industry and successfully transforming the image of budget travel. Yanolja executed its successful IPO and became one of the largest tech companies in South Korea, securing his multi-billion dollar fortune. He remains Executive Chairman, guiding the company's global expansion (partnering with SoftBank and Booking Holdings).

Lee Su-jin's social impact is structural, stemming from Yanolja's role in driving the digital transformation of the hospitality industry and providing affordable, transparent accommodation options for millions of travelers. The company provides thousands of stable jobs in the technology and travel sectors. His personal philanthropy supports various community and educational initiatives.

His career is a powerful narrative of resilience: an orphan who worked his way up from cleaning hotels to founding a multi-billion dollar technology company that transformed the industry.

Lee Su-jin maintains the professional, composed style of a technology executive. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects serious authority and stability, typical of a pioneer in the specialized travel technology sector.

Residing in Seoul, South Korea, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to technology innovation, strategic management, and the long-term, stable growth of the travel tech empire.
