Modernizing a SaaS Platform UI Without a Full Rebuild
A U.S.-based SaaS company refreshed the look and usability of its platform by modernizing the UI layer while preserving its existing technical foundation.
Context
The client is a U.S.-based SaaS platform serving multiple business verticals with a mature, widely adopted product. The underlying application framework was stable and well-established, supporting active customers and ongoing development.
As the market evolved, the platform’s visual design and user experience no longer reflected modern expectations, despite the system itself continuing to perform reliably.
Challenge
The client needed to modernize the platform’s UI and user experience without undertaking a full rebuild of the application. Reworking the underlying framework would have introduced unnecessary cost, risk, and downtime.
The challenge was to identify how far the existing system could be pushed visually and experientially—updating the interface, improving usability, and aligning with current market standards—while keeping the core architecture intact.
Solution
Unista evaluated the existing codebase and design patterns to understand both the constraints and opportunities within the platform. From there, we identified targeted UI and UX improvements that could be implemented with minimal changes to the underlying framework.
We delivered a series of design mockups and interaction updates that modernized the platform’s look and feel, strengthened visual consistency, and improved usability across key workflows. These changes were designed to integrate cleanly with the existing system, avoiding major refactoring while still delivering meaningful impact.
Impact
The platform achieved a refreshed, modern UI that better aligned with current market expectations while maintaining system stability. The engagement delivered a significant visual and experiential upgrade with fast turnaround and controlled cost, extending the lifespan of the existing platform and improving user perception without the risk of a full rebuild.
