Toronto, ON CA · shop437.com
Toronto swimwear and activewear brand founded in 2016 by Hyla Nayeri and Adrien Bettio, who remain majority owners and run the small in-house team. Products are manufactured at a female-run factory in China, and the founders have historically sourced fabric on trips to China and Indonesia. Corporations Canada's federal registry shows two Revolve Group executives now sit on 437's board, matching press reports of a 48 percent minority stake Revolve took in an apparel company in early 2026.
Factors
Ownership
37.6 inferredCA 52% · US 48%
Corporations Canada lists 437 Inc.'s directors as Toronto-based co-founders Hyla Nayeri and Adrien Bettio plus Raissa Gerona and Michael Karanikolas, both at Revolve Group's Cerritos, California address; Karanikolas is Revolve's co-CEO and Gerona its president of brand and partnerships. Revolve's FY2025 10-K discloses an equity investment in an unnamed private company, and trade press reported an $11 million, 48 percent minority stake in an apparel firm taken in January 2026, but no primary source names 437 by name, so the split above is estimated from the board composition and the reported stake size.

Manufacturing

Multiple press interviews with the founders describe a female-run manufacturing factory in China as the vendor's production partner, a claim attributed to the company's own website. No customs or import filing was checked to verify a revenue split across factories.

437's own site says the brand is powered by a small, all-women team based in Toronto, and press coverage from 2021 onward consistently describes the team as Toronto-based. Two of the four board seats now sit with Revolve Group executives in California, but that is recorded under ownership rather than the operating team.

Inputs
20.0 inferredother 100%
No current materials or supply-chain page was found. A 2017 interview describes the founders sourcing fabric on a trip split between China and Bali, and manufacturing is in China, so inputs are placed with manufacturing in the OTHER bucket as a best estimate rather than a confirmed current split.
- 437 Swimwear | Startups | Smith Magazine · press “In summer 2017, the pair spent two weeks in China and a month in Bali selecting fabric, creating new designs, updating the 437 Swimwear logo, and rebuilding the e-commerce site.”
