Why this combo
The decisions we made differently — and why they matter for fintech specifically.
Persona, Alloy, Onfido, Stripe Identity — in-app document upload with VisionKit document detection, real-time validation, save-and-resume.
Native iOS Plaid SDK, account linking, balance + transaction sync, micro-deposit verification. Reconciliation jobs on the backend so duplicates don't slip through.
Face ID / Touch ID gating on every sensitive action. Private keys live in the Secure Enclave, never extracted. Re-auth on background after configurable timeout.
WebSockets with intelligent throttling, background-mode disconnect, foreground reconnect. Our iOS trading-dashboard pattern is built around throttling, background-mode disconnect, and foreground reconnect.
APNs with notification categories (transaction, alert, statement). Time-sensitive interruption level for fraud alerts. Action buttons (approve / reject) for one-tap response.
Required regulator disclosures live in the design system (modals, labels, footnotes). Easier to update when your compliance team changes language.

Why Hayaiti
Fintech iOS apps have to feel as fast as a consumer app while carrying enterprise-grade auth, KYC, audit, and disclosure. The front-end of that stack — Plaid integration, biometric auth, KYC document upload, real-time market data — sits in our build playbook, with backend integration patterns for Stripe, Plaid, Modern Treasury, Increase, and Unit. We are NOT a registered investment advisor, broker-dealer, or licensed lender; you own the licensing and the regulatory relationship.

Shape of work
A small fintech needed to connect their internal book to a clearing broker's API and reconcile positions, cash, and corporate actions every night without manual intervention. Their existing approach was a CSV download + Excel macro maintained by one person.

FAQ
Yes — all three. Plaid Link via native iOS SDK, Stripe via Stripe iOS SDK, Apple Pay via PassKit. The full stack is in our fintech-iOS build playbook.
VisionKit for document edge detection, Persona / Alloy / Onfido / Stripe Identity for the actual KYC decisioning. In-app retake, save-and-resume, accessibility-friendly capture.
We're not a compliance firm. We ship UI that respects common regulator patterns and we'll flag obvious risk language. Final sign-off lives with your compliance counsel.
Yes — WebSockets with throttling and battery-aware reconnect. Our trading-dashboard pattern is wired this way. We have NOT built sub-millisecond HFT mobile UIs because that's not a thing.
Apple is strict on fintech. We know the common rejection patterns — missing privacy labels, ambiguous fee disclosures, in-app investment advice without disclaimers. We'll preemptively address them. We can't promise zero rejections, but we handle the back-and-forth.
Start with an audit, or jump straight to pricing. Either way, you talk to engineers — not a sales funnel.
