Challenge

Many DTC brands come to us with slow, bloated sites. Pages are heavy, too many scripts are loading at once, and things break down fast on mobile. A lot of this comes from years of patchwork development, apps piled on top of apps, unused theme code still running in the background, and Shopify logic that’s been stretched too far.

It’s common for teams to try and fix this by deferring scripts or compressing images. But that only solves part of the problem. What they really need is a rethink of how the site loads, how assets are delivered, and how interactions are prioritized across devices.

Approach

We focus on the frontend because that’s where users feel speed the most. Our goal is to reduce complexity, cut waste, and rebuild performance from the ground up. Every decision is measured by what it does for the customer experience, not just how it scores on a test.

Our process starts with a full audit where every template, script, and render is on the table. From there, we strip back anything that’s not doing real work, restructure what is, and rethink how and when assets load.

HERE'S HOW WE APPROACH IT:

  • Refactoring Liquid templates and removing unnecessary loops and includes
  • Slimming down JavaScript and eliminating redundant or blocking scripts
  • Cleaning up image strategy, including lazy loading, compression, and responsive sizing
  • Prioritizing key page elements to load early while delaying background components
  • Stripping out unused theme code left behind by outdated app integrations
  • Avoiding temporary hacks and writing solutions that hold up over time

Our fixes aren’t theme hacks or quick wins. They’re built to last and made to perform under pressure.

Execution & Implementation

We’ve applied this methodology across a number of DTC brands. Here are a few examples:

DYLAN'S CANDY BAR

  • Rebuilt the mini-cart drawer and delayed its load to prevent blocking the rest of the page
  • Simplified the way product assets load on PDPs, improving speed and scroll performance
  • Result: faster first paint, smoother add-to-cart experience

YUMMIE

  • Cleaned up image logic across homepage and product listings
  • Deferred galleries and removed heavy scripts that weren’t adding value
  • Result: better LCP scores and more stable layout on mobile

FRANCES VALENTINE

  • Reduced homepage complexity and cleared out unused theme files
  • Refactored PDP and collection templates to shrink DOM size
  • Result: faster load across high-traffic pages and fewer layout shifts
