Common problems & how founders solve them
The friction points South Korea builders keep hitting.
Local payment rails aren't obvious
Choosing between global Stripe and local providers matters Toss Payments + KakaoPay. Local card SDK integration is required.
Founders in South Korea over-scope their first product
We see it constantly: 6-month roadmaps, no launch. The 3-project cap is designed against exactly this failure mode.

- Composite pattern across 200+ builder interviews
Translation & tax questions block launch
Korean localization + local invoicing rules trip up 8 in 10 first-time founders.
