The smallest movement changes the world.
We find the hidden frictions even we never noticed, and fix them.
Who we are
We started out trying to clear away the everyday annoyances we hadn't even noticed ourselves. Chasing hidden problems one by one, we're already building three.
We don't decide what to build — what users run into every day comes first. So over what looks good, we pick what's genuinely easier for them.
Principles
Always user-first
Even when we want to build something, we drop it if users never actually hit the problem. If they hit it every day, we build that first, plain as it may look.
Small is the strongest
The world doesn't change on grand declarations. It changes when one daily friction disappears. So before the size of the market, we look at whether the friction is real.
Built to last
We don't make things you use once and drop. We make them so users can keep using them, every day, for a long time.
Built in the field
We don't decide it at a desk. We watch users actually use it, and fix it right there.
What's in motion right now.
PuzzLoader 퍼즐로더
A delivery driver lifts heavy boxes on and off hundreds of times a day, and at every stop hunts for which slot holds what. PuzzLoader automates that cargo bay. Load the boxes in any order, and they end up arranged into delivery order on their own.
The next stop's box is already waiting at the door before you arrive; the driver just takes it and steps down. The hardest last step — the vehicle takes it on.

At night, a worry swells far past its real size, and empty reassurance — “it'll be fine” — can swell it further. Yet most of what we dread never actually happens.
Tuck a worry into the drawer at night, and that same night a short letter closes out your day. In the morning you look again, clear-headed — and usually it's back to its real size.

On the subway or bus, the three to five minutes in your hand usually just fly by. Too short to open a textbook, too precious to waste.
Nalbyeorak is built for exactly those three to five minutes. With flashcards and spaced repetition, it brings back the expressions that land best on every trip — building them up, right until you walk in.

Three are in motion now — one in the field, one at the exam-room door, one almost ready. We're not stopping there.
