Marketing Manager, Brand and Product Marketing

About ZBiotics

At ZBiotics, we make genetically engineered probiotics that improve daily life. 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. GMO products like ours, built to create benefits for people in their daily lives, are the future. As the first to market, we believe it's our duty to set a high bar for product quality, safety, and transparency for others to follow.

In 2019, ZBiotics launched Pre-Alcohol, the world’s first genetically engineered probiotic designed to break down the alcohol byproduct that leads to rough mornings after drinking. In 2024, we launched a genetically engineered probiotic drink mix, Sugar-to-Fiber, that creates fiber from the food you eat. This revolutionary product helps to improve the diversity of gut bacteria and overall gut health.

With a full line of genetically engineered probiotics in development, our team is growing. We’re looking for people as excited as we are to build this new category of consumer products. ZBiotics is headquartered in San Francisco, and backed by venture investors including Y Combinator, Khosla Ventures, and Social+Capital, among others.
