Our Team

We're not just scientists. We're also musicians, artists, rugby players, cooks, surfers, woodworkers, rock climbers, and parents who care about enjoying life and doing good for the world at the same time.

Our Story

Our story begins over a decade ago, when now-CEO Zack Abbott was working at an HIV research lab. There, he had an idea: what if we could use genetic engineering to develop new probiotics – ones with specific, unique abilities to improve our daily lives?


Fast forward 7 years, a PhD in Microbiology & Immunology, and experience designing clinical trials, and Zack had what he needed to get started.

He founded ZBiotics in 2016, and today his vision has become a reality. ZBiotics launched the world’s 1st genetically engineered probiotic in 2019, and we haven’t looked back.
