The Challenge

FlowState required an intuitive mobile application capable of serving thousands of active banking clients with zero compromise on security, compliance, or UI fluid responsiveness.

03

Engineering & Integrations

Integrated Plaid for instant bank account linking and verification alongside Stripe Issuing for real-time virtual card provisioning and instant push telemetry notifications.

Business Impact

Launched on target in 12 weeks to an overwhelming 4.9★ App Store rating. Over 94% of users activated biometric logins, and cold-start rendering speeds clocked in under 2.5 seconds.
