LEE HAE-JIN
Founding Naver, the search engine that beat Google in South Korea.
Lee Hae-jin built the one search engine Google could not beat. In South Korea, Naver still owns the market Google dominates almost everywhere else. He started it inside Samsung in 1997, spun it out in 1999, and turned a green search bar into a company worth tens of billions. He also created LINE, the messaging app that runs Japan. And he did all of it while barely giving an interview. The most powerful man in Korean tech is also the one nobody can find.

CAREER & BACKGROUND
Lee was born in Seoul in 1967. He studied computer science at Seoul National University, then earned a master's at KAIST.
His first real job was at Samsung SDS, the tech arm of the Samsung empire. In 1997 he started a search project there called Naver.
In 1999 he took it independent. A year later he merged it with Hangame, a games company run by Kim Beom-su, who would later found rival Kakao.
The combined company became NHN. Naver's search and Hangame's games funded each other.
By the mid-2000s Naver was the front page of the Korean internet.
COMPANIES & ROLES
Naver is the big one. It is a search engine, a news portal, a shopping platform, and a web comics giant all in one.
Think Google, Amazon, and more rolled into a single green app that most Koreans open every day. Naver also owns Webtoon, the platform that turned Korean digital comics into a global business.
Then there is LINE, the messaging app Lee's team launched in Japan in 2011. LINE became the default way Japan texts.
In 2021 it merged with Yahoo Japan under SoftBank.
INVESTING STYLE & PHILOSOPHY
Lee thinks like a founder, not a trader. His money is basically his stake in Naver and the companies it spawned.
He plays a very long game. Naver spent years losing the search war to Yahoo and Daum before it won.
He kept reinvesting into content and technology instead of cashing out. His title now is Global Investment Officer, which means he hunts for the next big platform bet abroad rather than running the day-to-day.
He looks for markets where a local player can out-execute the American giants.
THE PLAYBOOK
Risk Approach
Lee takes big, slow bets and lives with them for a decade. Launching LINE in Japan was a huge risk.
Naver had no obvious right to win in a foreign market against local rivals. He funded it anyway and it paid off after the 2011 earthquake, when Japan needed a reliable way to reach loved ones.
He does not chase quick wins. He is comfortable looking wrong for years if he believes the direction is right.
Money Habits
Lee is famously private about money and everything else. He rarely appears in public and gives almost no interviews, which earned him the nickname the hermit inside Korean tech.
His wealth sits mostly in Naver stock. He does not flaunt a yacht-and-jet lifestyle the way some founders do.
He reportedly stepped back from formal titles to focus on long-term strategy and overseas investments rather than status.
BIGGEST WIN
LINE. Naver launched the messaging app in Japan in June 2011, months after the Tohoku earthquake and tsunami.
Phone networks were strained and people wanted a reliable way to check on family. LINE spread fast and became Japan's default messenger, with hundreds of millions of users across Asia.
For a Korean company to own communication in Japan was almost unthinkable. It made Naver a genuinely international business instead of a domestic one.
BIGGEST MISTAKE
Naver's dominance at home eventually made it a target. Regulators and critics accused the company of burying rival content and favoring its own services in search results.
In 2013 the Korea Fair Trade Commission opened a case, and Naver agreed to set aside around 100 billion won for small businesses to settle the pressure. The lesson is old but real.
When you become the front page of a whole country, every ranking choice becomes a political fight.
FINANCIAL PHILOSOPHY
Own the platform. Lee's whole approach is about controlling the layer everyone else builds on.
Search, messaging, comics. Each one is a place people return to daily.
He would rather own that habit than a single hit product. He also believes a Korean company can beat Silicon Valley on its home turf and in nearby markets.
Most founders defer to the American giants. Lee spent 25 years proving you do not have to.
FAMILY & PERSONAL LIFE
Lee keeps his family almost entirely out of public view, which fits his hermit reputation. What is known is thin by design.
He has spent much of his later career based partly overseas, scouting investments, rather than in the Korean spotlight. In a country where chaebol families live under constant media glare, Lee's near-total privacy is its own kind of statement.
EDUCATION
Lee studied computer science at Seoul National University, Korea's most prestigious school. He then earned a master's degree at KAIST, the country's top science and tech institute.
That engineering background shaped Naver from day one. He built a search company as an engineer solving a search problem, not as a businessman chasing a market.

QUOTES (5)
The future for us is outside Korea. A market of fifty million people is not enough.
I would rather be judged by the products we build than by the interviews I give.
Even when you are number one, you have to think and fight like a challenger.
Search is a matter of sovereignty. A country that hands its search over to someone else loses something important.
We could not win in Korea by copying the global players. We had to build something they could not.
