Born from frustration with broken mobile stores

In 2021, our founders Kenji and Yuki were leading mobile product teams at Japan's largest fashion retailer. They watched millions of yen in revenue evaporate every day because the mobile experience was simply unusable.

Buttons too small. Checkout flows that required fifteen taps minimum. Product images that took 8 seconds to load. Filters hidden three menus deep. They knew this was fixable — not with more technology, but with better design thinking.

mobux was founded to bring rigorous, research-backed mobile UX methodology to eCommerce teams who don't have the luxury of large internal UX teams. We've since grown to 24 specialists across Tokyo, Singapore, and London.

Every member of the mobux team has a background in either UX research, mobile engineering, or eCommerce conversion optimization. We don't do general digital design — only mobile commerce, and only with depth.

What we believe about mobile design

These aren't just words on a wall. They shape every design decision, every recommendation, and every line of code we write.

📱

Mobile First, Always

We never start a design on desktop. Every wireframe begins at 320px and expands outward. This isn't a principle — it's a non-negotiable process.

🔬

Evidence Over Opinion

Every recommendation we make is backed by data — user research, A/B test results, or peer-reviewed UX literature. We don't design by instinct.

🤝

Honest Partnerships

We tell clients what will actually improve their business, not what they want to hear. If a redesign won't help, we say so — before they pay for it.

Performance is Design

A beautiful interface that loads in 5 seconds is a bad design. Speed and aesthetics are inseparable in mobile commerce.

🌏

Global but Local

Mobile shopping behavior varies by market. Japanese users tap differently than American users. We research each context independently.

📊

Results Define Success

We measure everything we ship. A project isn't complete until we can prove it improved conversion, reduced abandonment, or increased revenue.
