DesignUX/UI Design

Make complex products feel simple.

We design web and mobile experiences that show people what to do, and help them get it done.

Our designers use AI to turn ideas into working interfaces, with engineers in from day one. You test sooner, refine faster, and development starts from reviewed components, not a picture.

Clear. Consistent. Quick to test.

  • Clarity

    Obvious next steps. Help users find their way, understand their options and finish what they came to do.
  • Consistency

    One product, not a patchwork. Layouts, typography, interactions and components that work together and look like your brand.
  • Speed

    Feedback while change is cheap. Test working interfaces early, and use AI to make revisions as the design evolves.
Our approach

From what users need to what they can click.

  1. Understand

    We look at user needs, business goals and technical constraints.

    Research and your product data show where design can make the biggest difference.

  2. Design & prototype

    We shape the flows and the visual direction, and use AI to build interactive prototypes.

    Engineers check feasibility and component structure as we go.

  3. Test & refine

    We test key tasks with real users.

    And check responsive behavior, accessibility, and the loading, empty and error states.

  4. Build & improve

    We stay with your engineers through implementation.

    Then we check the finished experience and let feedback and product data steer the next change.

Why Cleevio

Designers who build. Engineers who shape it.

We’ve built digital products since 2008, for clients and for ourselves. We know how a design decision plays out for users, for the build and for everything that comes after launch.

Our designers use AI to explore alternatives and build working interfaces. Engineers review the code and the technical calls while the design is still taking shape.

Earlier feedback, fewer rebuilds, and more of the design making it into the product.

Our stack

From visual decisions to working code.

We work in your existing design system and stack where we can, and pick tools around the product and the team that maintains it.

Design & systems

  • Figma
  • Design tokens
  • Storybook
  • shadcn/ui

Visual decisions, component documentation and reusable patterns, kept in one place.

Web interfaces

  • React
  • Next.js
  • TypeScript
  • Tailwind CSS
  • Vercel

Interactive interfaces your engineers can review and extend.

AI-assisted creation

  • Cursor
  • v0
  • Figma Make

Explore alternatives, generate interfaces and make revisions, with designers and engineers reviewing the result.

Validation

  • User testing
  • Product analytics
  • A/B testing
  • PostHog

Methods picked around the question, the users you can reach and the evidence you need. A/B tests where they fit.
