Erasing borders is, in the end, the work of people. SAZO is looking for the next one.
Borders are lines.
We erase them.
We cross borders with technology to connect the world.
Different languages, blocked payments, broken shipping. That boundary. Erasing the line looks vast, but in the end it happens in the hands of people, one at a time. Working at SAZO means erasing that line yourself.
'Zero distance to the world' becomes concrete, daily work. Not an abstraction, a problem to solve today.
GMV +1,290% in 10 months, monthly revenue +180%. Our speed isn't a slogan. It's proven in numbers.

SAZO WAY isn't a slogan on the wall. It's the standard by which we hire, evaluate and make decisions every day.
“What the numbers hide becomes visible when you follow one customer all the way.”
CX TeamInstead of just answering an inquiry, we follow one person's experience all the way to the root cause and change the structure.
“‘That's just how it's done' is the most suspicious sentence there is.”
EngineeringWe re-question what habit made fixed, and when we spot repetitive manual work we build the automation ourselves and roll it out to the whole team.
“The one who shares the failure first grows the team the fastest.”
Platform Sq.We share trial and error honestly in retros and document it for the next person, lifting the whole team.
“Difference isn't a risk, it's the opportunity we sell.”
Nagoya OfficeFacing differences in country, language and culture, we propose localization tuned to local language and UX before anyone asks.
“‘That's not my job' is the phrase we use least at SAZO.”
OperationsBeyond the task given, we coordinate our own schedule and resources and carry a problem all the way to a solution.
“One ‘yes, let's try' creates the next attempt.”
People TeamBefore we judge, we recognize someone's attempt first. Cheering the try over the result is where the next attempt begins.
I've been fascinated by software since childhood. After Incheon Science High School, I studied at Nagoya Institute of Technology as a Korea–Japan Government Scholarship recipient. Living in Japan, I felt firsthand how hard cross-border buying and selling is, and decided to solve the structural problems of cross-border commerce.
I loved games since childhood, running game servers and web/app services on my own at age nine. Before university I taught myself NLP, CV, ML, and cloud, then in my third year of college I founded SAZO, leading the early dev team and running the operating organization. Today I focus on getting the team to its next big milestone.
I studied Electrical & Computer Engineering at Seoul National University and started my career by founding an IT education platform. At Samsung C&T I led corporate finance and cross-border M&A and earned the CFA. After Michigan Ross MBA I led tech/AI strategy consulting at BCG in the U.S., and at KRAFTON's U.S. office I led IPO preparation, global operations, and M&A. I then led B2B business strategy at Amazon HQ. With that finance, strategy, and global background, I'm here to build SAZO's global growth together.
I started my career at LG Electronics and built large-scale distributed systems at Kakao Mobility and Banksalad. I then led commerce across formats: open marketplace at TMON, influencer commerce at Beauty Selection, and cross-border K-fashion as Head of Tech at Mediquarters. As a government-scholarship student in Japan I experienced the friction of overseas shopping firsthand; now I'm solving it with technology at SAZO.
Over 10+ years building services at NCSOFT, I sharpened the ability to solve complex problems with technology. I pick the right tool for the situation and build it myself when needed. From architectures like MSA and CQRS to AI/LLM-based services, I've designed both structure and detail, and I'm now applying that experience at SAZO to redefine cross-border commerce.
I led company-wide digital transformation and process automation at NCSOFT for 13 years. I then founded a company building LLM-based chatbots and DX solutions, became convinced of the potential of domain-specific AI, and joined SAZO AI.
A logistics strategist who understands the e-commerce floor, solving complex distribution problems through structure and operations design. I founded and ran a global fashion-focused 3PL, architected cross-border logistics for scale, and modularized logistics processes to fit each category. I see logistics not as cost but as scalable infrastructure, and I'm building SAZO's cross-border logistics from that foundation.
Seoul and Nagoya, different languages and backgrounds. We erase even that line and work as one team.
