Software studio, Daejeon
Your next customers cannot read your product
We design and build products that work in every language your customers actually speak. Community platforms, marketplaces, retail tools and student services, shipped and running in Korea.
Live in Korea: a community platform and marketplace for foreign residents, a nine-language camping car dealer with an AI assistant, a seven-language retail tool, and a Korean forms tool.

How we work
From an idea to something people use
Four stages. Most projects need all four, some need one.
- 01
Work out what to build
Most projects arrive as a rough idea and a deadline. We turn that into something you can actually ship, and we tell you what to cut.
- 02
Design and build it
Interface, database, and everything in between, by one team. Nothing gets lost in a handoff between the design file and production.
- 03
Make it work in every language
Not translation bolted on at the end. Built from the first screen to work in English, Korean, and whatever else your customers speak.
- 04
Ship it and hand it over
Deployed, running, and documented well enough that your own team can take it from us.
Work
Shipped and running
Four products live in Korea. Each one began with customers a business could not reach.
Keasy · Community platform
Keasy: the community app for foreigners in Korea
The problem
Foreigners in South Korea find housing, jobs and community through scattered KakaoTalk groups and word of mouth. Local businesses had no direct way to reach them.
What we built
An English-first app that puts guides, events, jobs and community groups in one place, and gives local businesses a direct line to foreign residents.
Partnership
Signed with Woosong University
An internship and employment agreement covering Korean and international students at Woosong, signed on 21 January 2026. We were already building for this community. The agreement is what turns that into placements.
The team
You work with the people who build it
No account managers. The engineers and designers here are the ones who would be on your project.
Writing
How we think about the work
Notes on building software that has to work for more than one kind of user.
Principles for Building Scalable Systems
The systems we run break at the second language, not the millionth user. What that costs in the schema, in search, and on a database we host ourselves.
Technical Debt When You Also Run the Servers
Most debt advice assumes someone else maintains the code. Here is what changes when the person taking the shortcut is the one it wakes up.
Making Code Reviews Actually Work
The person who approves your migration on Thursday is the person reading Postgres logs about it on Saturday. That changes what a review is for.
Tell us who you are trying to reach.
Send us the problem. We will tell you what it would take to solve, roughly what it would cost, and whether we are the right people for it. If we are not, we will say so.
