Perfect Day uses precision fermentation to produce animal-free dairy proteins that deliver the taste and functionality of conventional whey and casein without cows. The company's proteins are used by partner brands in ice cream, cream cheese, baked goods, and other products across global markets.
Perfect Day develops and supplies fermentation-derived dairy proteins to food and beverage brands through B2B ingredient sales and licensing. Its process uses microbes to produce whey and casein proteins with significantly lower environmental impact than conventional dairy farming.
Reports up to 97% less greenhouse gas emissions and significantly less land and water use compared to conventional dairy protein production.
