How 437 Saved 30% on Shipping and Scaled to the US
From shipping out of a Toronto basement to operating across 5 AMZ Prep fulfillment centers in Canada and the US, 437 partnered with AMZ Prep to cut costs, speed up delivery, and fuel cross-border growth.

From Basement Beginnings to Celebrity-Backed Activewear
437 is an elevated lifestyle brand designed for women who move through their day, whether it is Pilates, errands, or brunch. Pieces from 437 have been worn by Jennifer Lopez, Kendall Jenner, Bella Hadid, and more.
In 2017, best friends Hyla Nayeri and Adrien Bettio founded 437 while finishing their final year at Queen's University, naming the brand after their student house: 437 Johnson Ave. They started by shipping swimwear directly from Adrien's parents' basement, hand-packing every order.
After three years of swim and resort wear, they expanded into activewear, which now drives most of their revenue. But growth came with a serious logistics problem.
We hit a wall. Shipping and fulfillment were becoming too complex to manage on our own, slowing down our ability to scale.
The Challenge
As 437 grew, getting products to customers became a massive operational hurdle. High margin loss from cross-border fees and limited delivery options drove costs higher with every order.
- Skyrocketing shipping costs eating into profits
- Slow delivery times frustrating loyal customers
- Stressful peak periods (Black Friday, Cyber Monday, Boxing Day)
- Wholesale expansion challenges with varying vendor requirements
- Limited international shipping options blocking US growth
Every time we tried to grow, we hit a wall. Our basement mindset could not scale to the level our brand was reaching.
The Solution
Hyla partnered with AMZ Prep to streamline fulfillment across North America. With AMZ Prep's 50+ warehouse network, top tier carrier rates through 30+ regional and national carriers, and zone skipping technology, 437 immediately transformed its logistics operation.
AMZ Prep and eShipper completely changed the game. They did not just ship packages, they became part of our operations team. They track claims, provide insights, and make sure nothing slips through the cracks.
US Expansion with AMZ Prep
When US tariff changes hit earlier this year, AMZ Prep helped 437 expand fulfillment into the United States. A large portion of their orders were already shipping to US customers, making the move a natural next step.
- Used AMZ Prep's network optimization tool to evaluate Chicago, Texas, California, Florida, and Utah
- Jointly decided on Texas based on order data and shipping lane analysis
- 437's team visited the Texas facility in person before launch
- Now operating across 5 AMZ Prep fulfillment centers: 1 in Canada and 4 across the US
Having warehouses near our customers changed everything. Costs went down, delivery got faster, and we could finally expand wholesale in California without paying crazy fees.
Brand Packaging That Elevates the Experience
AMZ Prep and 437 developed a fully branded packaging experience featuring custom polymailers, promotional inserts, and thoughtful design elements that make each delivery feel like an extension of the brand itself.
Packaging is not an afterthought. It is part of the brand story, and for 437, that story starts the moment the package lands.
A customer in Vancouver told me, 'I got my package within 24 hours, and you guys are in Toronto! How did you do that?' That is when I realized how transformative this partnership really is.
