Ju Rhyu
A Korean-American Columbia MBA who, after seeing acne stickers everywhere in Seoul and nowhere in the US, bootstrapped Hero Cosmetics on Amazon in 2017 with a single product — the Mighty Patch. Five years later, Church & Dwight acquired Hero for $630M.
"Launch fast, focus on one product, sell where the customer already is."
— Ju Rhyu
Ju Rhyu was born in the US to Korean parents and earned an MBA from Columbia. She spent time working in Seoul, where acne hydrocolloid patches were a mass-market staple — and noticed that no comparable product existed at scale in the US.
In 2017, between roles, she bootstrapped Hero Cosmetics with a single SKU (the Mighty Patch) and launched on Amazon — deliberately skipping the DTC website / Shopify playbook in favor of meeting customers where they already searched. The patch went viral, became a Gen Z status symbol, and Hero expanded into Target, Ulta and Walmart while staying lean.
In September 2022, Church & Dwight acquired Hero Cosmetics for $630M. Rhyu remained as CEO post-acquisition and continues to run the brand.
One product, done well, sold on the platform the customer is already searching.
Bootstrapped capital efficiency over venture-funded growth-at-all-costs.
