About

Leaven Foods began with a simple realization.

Natural fermentations contain an extraordinary diversity of microbes — thousands of bacteria and fungi — with the ability to enhance the flavor and nutrition of the food we eat. Industries like beer and wine have an abundance of commercially available microbial options. However, for foods like bread, yogurt, chocolate, coffee, and other staples, the microbial tools available are shockingly limited.

Leaven Foods was founded to bridge this gap. By characterizing the incredible diversity of naturally occurring microbial communities, Leaven cultivates easy-to-use, defined microbial community cultures that don’t just replicate traditional fermentation — they celebrate and expand their potential. These tools are designed to empower everyone, from home bakers to large-scale producers, to craft foods that are more flavorful, healthful, and deeply connected to tradition.
