THE CURRICULUM
Week 0 to Demo Day. Here is all of it.
Every builder works on their own product. The room learns the same concept each week, and applies it the same afternoon.
Foundation
Open the starter inside LINE, understand who the user is, and ship a first deploy by the end of the week.
Data and the core workflow
Model your product’s data, then make the one thing it must do work end to end on a phone, with real data.
Productisation
Connect the product to LINE properly, handle every state a screen can be in, pass a security review, and run on your own domain.
Production
Feature freeze. Harden, monitor, pass the quality gate, document what is not done, and rehearse the demo to time.
Show it, keep it
Five minutes each, live on a phone, in front of founders, agencies and future applicants. You keep everything you built.
The full curriculum is in the app. Every session, the homework, the milestones and the quality gate, in the same place you track your application.
Add us on LINE to read it →WHAT IT COSTS
Two numbers. Both in the open.
Tuition for the four weeks, and what your app will cost to run afterwards. Nothing is saved for a sales call.

You do not need to be an expert programmer.
BuildOn Marketplaces is for people who can work comfortably on a computer, follow basic technical concepts and are willing to build intensely for four weeks.
✓
Basic technical or programming skills are enough.
AI-assisted and vibe-coded projects count. You should be able to follow what is happening and explain what you built.
✓
English instruction.
Classes, technical discussions and group questions are conducted in English.
✓
Bring your own laptop.
You need a computer you can use in class and between sessions.
✓
Commit to the four weeks.
Two four-hour sessions each week, in Taichung or live online (the founding cohort picks the format), plus time between sessions to keep building.
