Executive Summary

Yeogirl Yun is the founder of Gshopper, a global cross-border e-commerce marketplace that connects consumers in more than 200 countries with electronics, home goods, sporting equipment and other products sourced from brands in Japan, Korea, France and the United States. He is a serial technology entrepreneur whose earlier companies sat at the origins of consumer web search and comparison shopping: mySimon, the comparison-shopping engine acquired by CNET in 2000, and Wisenut, a large-scale web search engine acquired by LookSmart in 2002. Trained as a computer scientist at Stanford and Seoul National University, he has built companies across the United States, China, Japan, South Korea and Singapore.

Career Highlights

• Founded Gshopper, a cross-border marketplace reporting more than 10 million orders shipped to over 200 countries, backed by investors including Eight Roads, Oak Investment Partners and ClearVue Partners.
• Founded mySimon and served as its Chief Technology Officer; the company was acquired by CNET in February 2000 in a transaction reported at $700 million.
• Founded the Wisenut search engine in 1999 and built it into one of only two engines of its era indexing more than one billion pages; LookSmart acquired it in April 2002.
• Founded Become.com in 2004, serving as Chairman and Chief Technology Officer through 2007.

Professional Journey

Yun’s career began in search. After completing a master’s degree in computer science at Stanford, he founded mySimon in 1998 as a comparison-shopping engine built on parallel search techniques — software agents that queried many merchant sites at once and normalised the results. The approach was distinctive enough that CNET acquired the company in February 2000, at the peak of the first web commerce boom, in a deal widely reported at $700 million.

He did not stay inside a larger company. In 1999 he founded Wisenut, a general-purpose web search engine, and served as its chief technology officer. Wisenut’s ambition was scale: it became one of only two engines of the period to index more than a billion web pages, a benchmark that mattered commercially at a time when coverage was the main axis of competition among search providers. LookSmart acquired Wisenut in April 2002.

A third search-adjacent venture followed. From 2004 to 2007 Yun was founder, chairman and chief technology officer of Become.com, another shopping search product. The through-line across all three companies is the same technical problem — retrieving and ranking product information across a fragmented merchant web — approached from a different commercial angle each time.

Gshopper represents the shift from search to transaction. Rather than pointing shoppers at merchants, the platform handles the cross-border sale itself, with subsidiaries across more than a dozen countries and a Singapore base, and reports over $200 million raised from investors including Eight Roads (formerly Fidelity Growth Partners Asia), Oak Investment Partners and ClearVue Partners. Gshopper’s own materials describe more than 10 million orders shipped to 200-plus countries.
