Redesigning a Spanish microloan app using a system of 7 AI agents — from user research to tested wireframes.
An outdated interface built for web, not mobile
Dineo.es is a Spanish microloan platform offering up to €500 in fast credit. Its mobile experience relied on an outdated interface and legacy design system that created usability and consistency issues across the core user journey.
The design system carried three conflicting typefaces, no dark mode, and components that failed basic WCAG accessibility checks. The onboarding asked for everything at once — a web form adapted to small screens, not a native mobile experience.
"The user doesn't need to be persuaded — they already want the loan. They need to be trusted, with accurate costs, plain language, and a flow that respects their urgency."
