Credidi (水滴發票) — 1.96M-User Consumer Finance App
Our own product, built and operated by the team for three years. AI image recognition on paper and electronic invoices, Taiwan e-invoice carrier integration, and named App Store Best App of 2021. Wound down in 2023 due to macro conditions (rising rates and slower-than-expected open-banking progress) — a business-environment call, not a technical or product failure.
- AI image recognition: one-tap scanning of both paper and e-invoices
- Taiwan e-invoice carrier integration and webhook reliability with back-fill
- Re-architected Firestore / Cloud Run to hold cloud costs at million-user scale
- A/B tested an AdMob + subscription dual business model
