How Mack Weldon Compounded Its Way to a World-Class eCommerce Experience
“Working with Anatta does not feel like outsourcing. They really feel like they’re part of your team, just not physically in your office.”

Impact
5+ Years of Compounding Growth
What started as a referral in 2020 led to over five years of partnership: two site redesigns, a rebrand, 34 product launches, 5 BFCMs, and 130+ A/B tests.
+25% Conversion From a Single Integration
Yotpo Reviews on product pages lifted conversion 25%, AOV 6%, and add-to-cart among new visitors 15% — one example of an integration program spanning 31 apps and systems.
A 90% Leaner Catalog, A Faster Site
Re-architecting the storefront on Shopify's native capabilities collapsed 3,000 products to 300 and removed CMS overhead, cutting infrastructure costs.
The Challenge
Mack Weldon Seeks a Technology Partner
Mack Weldon had already made the big move. The menswear brand had replatformed from Spree to Shopify, and its sights were set on a world-class shopping experience. What it couldn't find was the team to get there.
Freelancers lacked the depth. Agencies felt like outsourcing. And an in-house team was slow to assemble and hard to scale. Each model solved part of the problem, but none fit the way Mack Weldon wanted to work.
Mack Weldon wanted a partner that could match the pace and care of an internal team, at the breadth of a full department.
The search ended with a referral. An existing Anatta client pointed Mack Weldon to the team, and the partnership began in 2020.
Overnight, we went from zero to 60. Anatta provided us with a full-blown team of front-end developers, back-end developers, QA people, project managers, designers. They had the whole team ready to go.

The Solution
How the Partnership Adapted and Grew With Each Sprint
A Team, Not a Ticket Queue
Anatta was embedded alongside Mack Weldon's team from the first sprint. The early roadmap set the tone: deep heuristic audits, full ADA compliance, a CMS integration that gave marketing autonomy over content, and a donation program shipped along the way.
The partnership's character showed early, when a planned returns-platform rollout collided with how Mack Weldon sold bundles.
The way we were doing bundles on our site was not going to work with the new tool. Anatta not only built the functionality we needed to create bundles the way we had been, but on top of that built a feature we've talked about having for years.

An Experimentation Engine That Never Switched Off
What began as optimization became infrastructure: 130+ A/B tests were launched across the partnership, spanning navigation, product pages, checkout, cart, and homepage. The optimization program was backed by qualitative usability studies that validated major features before development, catching friction while it was still cheap to fix.
The engine produced compounding wins. When Anatta implemented Yotpo Reviews on product pages, conversion rose 25%, average order value rose 6%, and add-to-cart among new visitors climbed 15%. When testing showed customers preferred bundling directly on the product page over a separate builder, Anatta integrated it natively. The bundle experience went on to generate over $2M in sales.
I can bring up problems we're facing or run through ideas I've had. Anatta will tell us what they think, help us understand what's possible, and share what they've done in the past. They bring a confidence-inspiring approach.

Expanding the Map
As the foundation held, the roadmap widened. Anatta integrated Global-e to take Mack Weldon international with currency selection, duties and taxes, and region-aware content logic. The brand was now available beyond the US and Canada for the first time. Product experiences also kept pace: Anatta launched a redesigned kit builder, reimagined product detail pages, and built dynamic acquisition landing pages to convert paid traffic.
Anatta Re-Architects Its Own Work
Years earlier, working within the platform's constraints at the time, the partnership had adopted a catalog architecture that treated every color variant as its own product. Thousands of products stood in for hundreds. It worked, but it taxed every third-party integration that touched it.
When Shopify's native capabilities matured to support the catalog directly, Anatta proposed retiring the original architecture. Over four and a half months, the team rewrote the entire storefront on native Shopify architecture. The new architecture collapsed roughly 3,000 products to 300 and removed the standalone CMS in favor of Shopify's built-in tooling. The change simplified every vendor integration while cutting infrastructure costs, and the Mack Weldon site emerged faster than it had ever been.
The Results
What 5+ Years of Partnership Can Achieve
The Mack Weldon and Anatta partnership proved itself quickly. And then kept proving itself, year after year.
Fast First-Year Proof: In the first year of the partnership, Mack Weldon saw revenue rise 23%, recurring revenue climb 44%, conversion increase 9%, and average order value grow 5% — early validation that the embedded-team model could move the numbers that matter.
A Compounding Optimization Record: 130+ A/B tests, 31 app and system integrations, 34 product launches, two full site redesigns, a rebrand, and a replatform — one accountable partner across all of it. Every Black Friday since the partnership began launched without incident.
A Storefront Rebuilt Lighter: The catalog re-architecture collapsed roughly 3,000 products to 300, a 90% reduction. It also removed CMS overhead, simplified every third-party integration, cut infrastructure costs, and made the site faster than it has ever been.
From Two Countries to the World: With Global-e integrated, Mack Weldon expanded beyond the US and Canada into international markets, with currency, duties, and localization handled natively in the shopping experience.
A Foundation That Carried the Brand Omnichannel: On the strength of its digital growth, Mack Weldon has expanded into physical retail, opening eight stores and securing eight retail partnerships, with its eCommerce foundation holding steady underneath the leap.
Looking Forward
Five years in, the arrangement that started as a referral is still the operating model: one embedded team, a testing program that never switches off, and a storefront re-architected whenever the platform makes a better answer available.
