Product design

We turn your ideas into interactive, testable designs. From early wireframes to pixel-perfect prototypes, we help you define and visualise your product before a single line of code is written.

What we offer

UX research & product discovery

We run workshops, interviews, and audits to understand your users, align with your goals, and define what should (and shouldn’t) be built.

UI/UX design

We craft mobile-first, accessible interfaces tailored to your audience, from MVP to scale-ready platforms.

Design systems

We build design systems that evolve with your product and ensure consistency, clarity, and easier developer handoff.

Developer-aligned delivery

Designs are built with implementation in mind: annotated, structured, and aligned with real-world constraints from day one.

How we work

We begin by understanding your business goals and user needs.

Then we translate that into design logic, flows, and visual output.

You will get constant checkpoints, real-time collaboration, and versions ready for testing and iteration.

Why MarsBased

Product thinking

We do more than visual design. We think through usability, business logic, and how the product should evolve post-launch.

Senior designers only

Our product designers have years of experience shipping real products. No juniors. No fluff.

Seamless handoff

We design with implementation in mind. Our devs and designers speak the same language, reducing handoff friction and costly rework.
