01 · Problems

Sound familiar?

Issues every solo academy owner knows.

Notes scattered across KakaoTalk

Attendance in a chat, tuition in DMs, progress in a notebook — nothing in one place.

Missed tuition tracking

Hard to remember who paid, when you reminded them last. Parent messages get awkward.

Forgot to call about the absence

You meant to call the parent before class. Then class started and you forgot.

Founder's note

Why we built it, how we run it — quantitative.

I grew up with parents who ran an academy. I started with admin work in their elementary academy.

Big academy software is overkill for 50 students; KakaoTalk + Excel misses things.

We target 50–150-student solo academies — three workflows only: attendance, tuition, alerts.
