FAQ

Frequently Asked Questions

We have a massive legacy backend. Will a UI redesign force us to rewrite our code?

Not if done correctly. We practice "Safe UX Refactoring." We audit your current API structure and data constraints first. We redesign the visual layer (UI/CSS) and user flows to improve usability without requiring you to change your backend logic or database architecture. It’s a facelift for the engine you already have.

Our product is incredibly complex (ERP/Logistics/Fintech). Do you actually understand our business logic?

We specialize in "boring" high-load sectors. We don't guess—we start with a Logic Audit. We invest time to understand your terminology, user roles, and data dependencies before drawing a single pixel. We treat design as engineering: if it doesn't match the business process, it's not approved.

How do you hand off designs to our developers? We don't want "just pictures."

We speak your language. You get a Component-Based System (compatible with React/Angular/Vue). We deliver design tokens (colors, spacing, typography variables), Dev Mode specs in Figma, and interactive prototypes for complex animations. No "visual guessing"—your devs get a blueprint.

We work in 2-week Agile sprints. Can you integrate into our workflow?

Yes. We reject the "Waterfall" agency model. We embed into your Jira/Linear process. We can deliver "Just-in-Time" design updates—preparing the UI for the next sprint while supporting devs on the current one. We become your dedicated design unit.

How exactly does design reduce Churn? It sounds abstract.

It's purely mathematical. Churn in SaaS often happens because users feel "stupid" or overwhelmed (High Cognitive Load). By simplifying onboarding, adding "Empty States," and clarifying navigation, we reduce the Time-to-Value. If a user gets value in 5 minutes instead of 50, they stay.

Do you support us after the launch? Or is it a one-time project?

We prefer long-term partnerships. After the main release, most SaaS clients switch to our Dedicated Team (Retainer) model. We stay on board to design new features, run A/B tests, and maintain the Design System so your product doesn't degrade over time.
