House of Mammoth was founded in 2018 by Benjamin Esposito, a New York-based artisan perfumer whose path began with handmade bath soap, moved into traditional wet shaving, and eventually became a deeply personal fragrance house built around storytelling. The brand started with a simple but unusually sincere mission: to put something good into the world through luxury shaving products and original perfumery while raising awareness and funds to fight human trafficking. That sense of purpose still runs through the Mammoth catalog, where scents like Sonder, Hygge, Alive, and Fu Dao often feel less like straightforward fragrance concepts and more like small emotional essays in soap, splash, and perfume form. House of Mammoth has since grown beyond its original shaving roots, but it has kept the intimate, maker-led quality that makes the best artisan brands feel as much like a point of view as a product line.
