The opportunity 

At ZBiotics, we make genetically engineered probiotics that improve daily life. Our mission is to create, brand, and sell GMOs that people love. As a group of motivated, yet down-to-earth people, we are fueled by two things: a love for science and a commitment to being people-first. As the first company to bring GMO probiotics to market, we’re committed to setting a new standard for transparency, quality, and innovation.

In 2019, we launched the world’s first genetically engineered probiotic: ZBiotics® Pre-Alcohol, a 14mL probiotic drink designed to break down an alcohol byproduct that leads to rough mornings after drinking. Since then, ZBiotics’ business has continued to grow rapidly year over year, and in 2024 we launched our second product: ZBiotics® Sugar-to-Fiber, a genetically engineered probiotic that creates fiber in your gut using sugar you already eat, contributing to microbiome health.

ZBiotics is headquartered in San Francisco and backed by venture investors including Y Combinator, Spring Tide Capital, and Khosla Ventures, among others.
