|---|---|---|
| Parent ecosystem | Commerce, payment, telecom, securities, trust bank, regional bank, or independent group | Explains customer acquisition and cross-sell cost. |
| Account scale | Date-stamped account count or customer base | Useful only if dated; account count can move quickly. |
| Deposit franchise | Deposit balance, salary account, settlement account, or promotional balance | Determines funding stability and primary-bank conversion. |
| Lending mix | Mortgage, card loan, personal loan, business loan, securities collateral, or no meaningful loan book | Drives ROA, credit risk, and capital use. |
| BaaS / API depth | Partner branches, API services, white-label accounts, corporate API | Separates consumer app banks from platform infrastructure banks. |
| Securities / payment adjacency | Brokerage, wallet, card, QR payment, quick deposit, FX | Explains daily frequency and revenue beyond net interest margin. |
| Regulatory stack | Bank license, bank agent, electronic payment agency, funds transfer, prepaid, FIEA | Prevents UX from being confused with legal function. |
Model Notes
Ecosystem Retail
Rakuten Bank, PayPay Bank, and au Jibun Bank are ecosystem banks. Their public distribution surfaces include commerce, telecom, card, wallet, points, securities, and everyday payment behavior. Primary-account conversion fields include salary deposits, recurring payments, mortgages, cards, and high-frequency transfers.
BaaS / White-Label Banking
SSNB operates the NEOBANK partner-led BaaS model. Minna Bank discloses partner-branch and API-provided banking models. These are distribution architectures where the customer journey may be controlled by a partner brand while the bank account remains with the bank.
SME / Corporate API
GMO Aozora Net Bank is the corporate API / SME banking anchor. Its public product fields include business-account opening, transfers, accounting, payroll, SaaS, and platform settlement flows.
Asset-Formation Specialists
Sony Bank and au Jibun Bank show how a net bank can compete through mortgages, FX, securities adjacency, and household asset-building rather than pure payment frequency. Compare them with online brokerage competition when the customer journey moves from deposits to investment products.
Regional Digital Banks
UI Bank and 01 Bank are regional-group digital-bank examples. Public comparison fields include digital deposit channel, branch-footprint extension, customer segment, and group-bank linkage.
