We don't pitch products to clients.
We run them.
Then we let you in.
Most shops never use their own product. They just take contracts.
We did the opposite: built eight, run them ourselves,
and the work comes in on top of that.
Korean PM standards + on-the-ground Vietnam dev.

FAQ
A Korea–Vietnam IT studio registered as legal entities on both sides. Seoul runs planning and strategy, the Hanoi core runs development, and Ho Chi Minh City runs sales and local execution, all on one build queue. We build and operate eight of our own products, and build clients' web and apps with the same team.
Korea HQ is in Mapo-gu, Seoul; the development core is in Hanoi (Cau Giay), Vietnam; and the sales and local-execution base is in Ho Chi Minh City. We operate across two timezones at once.
Corporate websites, e-commerce, web apps, mobile apps and maintenance, plus AI-driven process automation (AX). We plan in Korean from Seoul and ship from Hanoi.
Yes. Our Hanoi and Ho Chi Minh City core builds Vietnam websites and homepages to Korean design standards. See the web development service page for details and start with a free quote.
Yes. We act as a bridgehead, connecting market data, entity and tax setup, and local execution staff: everything a Korean company needs to enter Vietnam, in one place.
