FOUR THREE SEVEN is a lifestyle brand founded by best friends Hyla Nayeri and Adrien Bettio in 2017. While studying abroad, they noticed a gap in the swimwear market and launched 437 using their savings after graduation. With no investors or social media following, growing the brand was a challenge. After 18 months, they had their first sell-out moment. Initially focused on swimwear, 437 expanded into activewear, now the brand's primary revenue driver. Celebrities like Jennifer Lopez and Kylie Jenner have worn 437. The Toronto-based, all-women team remains self-funded, with Hyla and Adrien featured on Forbes 30 Under 30 in 2020.
