Think Dirty

Think Dirty is a private consumer health technology company best known for its mobile app and related platform that helps users evaluate ingredients in beauty, personal care, household, baby, and pet products. The company provides barcode scanning, ingredient analysis, product ratings, and cleaner-product discovery tools intended to help consumers make more informed purchasing decisions. Its methodology is based on publicly available safety data from government and nonprofit sources in North America, with ratings focused on ingredient-related health risk rather than brand marketing claims. Founded by Lily Tse and launched as an app in 2013 after being founded in 2012, Think Dirty operates as an active for-profit business with premium subscriptions, verified-brand services, and e-commerce style product discovery features. It is healthcare-adjacent rather than a biotech or pharmaceutical drug developer.
