Challenge

A fast-growing credit business that asks both sides for financial trust, on products that didn't look or work like one company.

  • Brand

    Little perceived credibility for a product that asks producers and students for financial trust, and a different visual language in each product.

  • Service

    Five interdependent products and departmental silos hid friction across acquisition, conversion, activation and retention. No one could see where the journey broke.

  • Product

    Producers were lost in the navigation, with no view of delinquency in their portfolio; checkout let identity fraud in; and students who fell behind had no way to resolve their debt on their own.

Key actions

  • One brand both sides can trust

    Market research, positioning and a visual and verbal identity applied across the ecosystem, rolled out product by product.

  • One map of the whole service

    The end-to-end journey mapped with the CX team across every department and system, with fixes prioritized by a weighted matrix built from user interviews.

  • One design system in the developers' stack

    Tokens on Tailwind and Shadcn with light and dark themes, so every change flowed straight into prototypes and front end.

  • A safer checkout

    The credit request split into sequenced steps, with AI identity verification (document, selfie and liveness) and minor-age blocking built into the flow.

  • Producers' finances in their pocket

    Key web features brought to a new mobile app in 30 days, and a redesigned web app with clear navigation and delinquency visibility.

  • Self-service debt renegotiation

    A renegotiation website for students with overdue payments, designed in 30 days and working alongside AI-assisted collections.
