Style Guide
define branding & art direction

We define guidelines for the usage and creation of stylistic elements to ensure visual brand consistency across your product or website.

  • Style Guide

    Based on your branding, we define your colour palette, typography, and other stylistic elements and create guidelines for their usage.

  • User Interface Components

    We define and create reusable interface components such as buttons, cards, and form fields, using the guidelines from the style guide.

  • Art Direction Alignment

    We align with you and other stakeholders on the styles, components and other artistic direction before we begin designing your product’s screens.

Wireframing & Prototyping
design high fidelity wireframes

We design a custom interface, focusing on usability and accessibility, while implementing your brand identity & styles across all screens.

  • Mid Fidelity Wireframing

    We increase your sketches or low fidelity wireframes to mid fidelity, adding elements from the style guide to make the designs clean, visually interesting, and consistent.

  • High Fidelity Prototyping

    We increase the level of detail on the design to exactly how we want it to be built. We ensure each detail helps the user to quickly and easily achieve their goals, while wanting to see more.

  • Responsive Web Design

    Your screens are optimised for different devices to ensure that your users always see the design perfectly on their various screen sizes.

Testing & Iteration
Get feedback from target audience

We validate the effectiveness of the new interface and styles through user testing, perfect the designs, and smoothly hand over to the developer.

  • Usability Testing

    We test the new design on users to assess its usability, accessibility, visual appeal, to ensure that we have designed the right thing and to discover how to improve it even more.

  • Iteration

    We gather insights from the results of the user testing and use them to make the last changes to make the designs as usable, accessible and visually appealing as possible.

  • Developer Handoff

    We perfect the designs ready to be built by the developer and provide them with documentation to ensure it can be built quickly and exactly as planned.


Our Approach

Your Journey

We will work together from product vision to development.



Learn about your users and their painpoints, so we know what to design and can base our work on real needs. This drives all our aesthetic decisions.


Define style guide

Based on the art direction decided in Phase 1, this will ensure design consistency and greatly speed up the design and development phases.



Usable, accessible, navigable, learnable screen design with cohesive visual branding will increase trust, interest, and loyalty in your users.



Ensure the designs are successful: that users understand and are highly satisfied with the new interface and visual communication.



Perfect the design in high-fidelity responsive wireframes and ensure a clean handover to development.
