Emily Stein

Emily Stein is a microbiologist turned founder and CEO of Primal Health, the Minneapolis life-sciences company behind Daily Dental Care for people and TEEF for Life for pets. Trained at UC Berkeley and Stanford, she spent more than a decade building SMMRT (Selective Microbial Metabolism Regulation Technology), a 'carrot and stick' approach that starves harmful mouth bacteria and feeds the helpful ones instead of nuking everything. Holder of 18 patents and a five-time startup founder, Stein pivoted from humans to dogs when dentists balked, a move she says saved the company. Her stated goal: to be in every mouth at least once a day.
