About us 
At Shiru we believe that food should be delicious and nourishing without negatively affecting our planet. Acknowledging our growing global population as well as the imminent effects of climate change, Shiru’s mission is to create better protein ingredients that will catapult us into a sustainable food future. 

With our mission in mind, Shiru makes high quality, functional food proteins through better leveraging our precious environmental resources. To do this, we employ technologies originally  created to solve problems in adjacent industries, including computational biology, machine learning, and industrial fermentation and bioprocessing.

We apply computational intelligence to find the most functional natural food proteins in the world, harnessing the inherent ability of microflora to produce them. We then partner with food and beverage companies to incorporate these unique protein ingredients into everyday products. Shiru is now expanding our team of dedicated professionals across multiple disciplines to make enhanced protein ingredients for a better world.
