## 2. Business role

- Offers bundled payment methods for small merchants and EC shops.
- Bridges payment gateway, merchant settlement, delivery / collection services, and lending-related services.
- Complements GMO-PG's enterprise PSP role with a more SME-focused surface.

## 3. Why this standalone page matters

GMO-PG is the listed group anchor, but GMO Epsilon is an operating subsidiary with distinct merchant segment, licenses, and product economics.
