Case study / Storefronts
Hum: a steadier storefront for streetwear launches
A streetwear brand with sales concentrated around launches, and the storefront work we did for them.
Short answer: Hum is a Vietnamese streetwear brand with sales concentrated around product launches. Layouts shifted while loading, and mobile checkout slowed at peak traffic. We built a new design system, removed the layout shifts, reworked the mobile checkout and built campaign and launch pages for peak traffic.
Problem
Hum sells on a hosted e-commerce platform, and its sales gather around launches. Page layouts shifted while loading, and mobile checkout slowed when traffic peaked.
Approach
We started with Fix & Stabilize, then moved to Custom Software. A new design system came first, and the layout shifts went away. We then reworked the mobile checkout and built campaign and launch pages for peak traffic.
Result
Hum has a new design system, a storefront without layout shifts, a reworked mobile checkout and launch pages made for peak traffic.

What changed
- A new design system. One set of building blocks for the storefront.
- No more layout shifts. Pages hold their shape while loading.
- A reworked mobile checkout. Built for the moments when many people buy at once.
- Campaign and launch pages. Built for peak traffic.
