FAQ // OBJECTIONS

Q01 ·Why not just use a Japanese agency?

Japanese agencies are built for large coordinated projects with multiple stakeholders — ¥5–10M budgets and 4–6 month timelines reflect that overhead. ZeroEn is one engineer, fixed scope, fixed price — optimized for the exact window between funding and launch.

Q02 ·What happens if we want changes after delivery?

Out-of-scope changes are billed at ¥15,000/hr. Every request gets an upfront time estimate before any work begins.

Q03 ·Do you take equity or revenue share?

No. Fixed price only. We don't take equity, SAFE notes, or revenue share.

Q04 ·Who owns the code?

You do, after final payment. Code ownership transfers on delivery — no lock-in.

Q05 ·What does 'bilingual from day one' mean?

Every component is built locale-aware with next-intl. EN and JA routing, fonts, formatting, and JP UX patterns are architecture decisions — not afterthoughts.

Q06 ·How do I get started?
