MAISON831 is not a web agency.It is where technology, people and space meet, and where a conversation across the table turns into a product that ships.
MAISON831 exists to connect the people who build, the people who start, and the people who write the code. We make digital products for a living. That work rarely begins with code. It usually begins with a room, a conversation, and someone trying to describe something that does not exist yet.
So we built a place that could hold all of it. A studio that ships software, a community that meets every month, and a room you can actually walk into.
We use AI heavily.But AI is a tool, and it stops there.What gets built, and how it is structured, is decided by people.
Product, design, engineering and operations sit on the same team.The same people think it through and decide, from the first conversation to the last release.
A good room is not finished by its features.We design how people stay in it, meet in it, and remember it.
Relationships create the opportunity,the product is what remains.
Product, engineering and operations are one team. We reach for tools quickly, but what to build and how to build it is decided by people.
Built for you, not from a template
Company sites, landing pages and web applications, designed without a template. We look at how the business actually works before we build.
iOS · Android
From a first MVP to a product on the store. We weigh shipping fast against still being able to change it later.
Every month, in the same room
Founders, designers and engineers in one room, once a month. No stage pitches, no business-card networking.
South-facing light, up to 18
A 44㎡ studio with a kitchen, a wine bar and a projector. Sized for small classes, workshops and private gatherings.
We do not publish case-study details or live links. If a particular piece of work interests you, ask us about it.
Daechi exam-prep academy
Attendance, counselling notes, grade trends and parent reports. A whole day of academy operations pulled into a single screen.
Smart Classroom
We split the product in two: a shared tablet that hangs on the classroom wall, and a separate admin system for teachers. No personal data is ever on screen in front of the children.
KinderQ
A native iOS app built with SwiftUI and MVVM, wired up with Kakao sign-in and an XcodeGen build pipeline.
JS High School badminton club
Membership, monthly dues, guest fees and lesson scheduling for an adult club. A group chat and a spreadsheet, replaced by one link.
Family project
An offline-first web app for a five-year-old. No network, no account — it just opens on a tablet in the back seat.
Public kindergarten, Gangnam, Seoul
A pinwheel symbol that only reads once it moves, matched to a wordmark that holds up on both a building sign and a small printed form.

The gatherings here are mostly quiet ones. Sometimes colleagues come looking for something to do together outside of work; sometimes people from the same industry bring out what they are into. We think about the conversation that lasts before we think about the size of the room.
A team from a game studio in Pangyo comes to MAISON831 each month for their activity group. A private programme built around trying something new outside of work and letting colleagues meet each other properly.
Enquire about hiring the spacePeople working in games got together and talked about the things they care about away from the job. A small gathering, a slow single malt, and a lot of discovering what everyone else is into.
