Supergoop!: Holly Thaggard : How I Built This with Guy Raz In 2005, the trajectory of Holly Thaggard's life completely changed when a good friend of hers was diagnosed with skin cancer. Holly realized that most people weren't taking sunscreen seriously, so she sidelined her vocation as a harpist to dive headfirst into the unfamiliar world of SPF. After a false start trying to market her sunscreen to elementary schools, Holly pivoted to retail, hiring a publicist she could barely afford. She eventually got her products into Sephora, a success that helped turn Supergoop! into a multi-million dollar brand.
