How do you approach a full UI/UX redesign for a growing app?

We’re scaling our platform and have realized the current UI/UX doesn’t hold up anymore—things are cluttered and users seem confused during onboarding. Has anyone here tackled a full UI/UX overhaul? What should we be focusing on first—user flows, interface design, or something else?

Redesigns can definitely shake things up. Curious to see what others suggest here.

The first thing I’d recommend is mapping out the key user journeys that your users rely on the most. Here's where you might want to look into ui and ux design services to get a structured external perspective. From my experience, working with professionals can help spot usability gaps you’ve grown blind to. In our case, we started with user interviews and click data, and it was shocking how much friction people were experiencing on basic tasks. After that, we cleaned up the visual hierarchy and simplified navigation paths. A good redesign should not just look modern—it should remove decision fatigue and guide the user naturally. Take your time with wireframes before jumping into visual design.
