Current obstacles
Cost competitiveness with dairy wheyFermentation whey must match dairy pricing to win adoption in cost-sensitive food manufacturing.
Physics limits
Fermentation throughput limits outputSpeed of microbial growth and protein production sets the ceiling for annual facility output. Faster fermentation increases capacity.
How it works
3 parts
Genetic engineering
Programming microbes to make whey
Perfect Day modifies Trichoderma reesei to produce beta-lactoglobulin. Bioreactors ferment the engineered organism to produce and secrete the protein.
Harvesting protein
Purifying fermented whey
The secreted beta-lactoglobulin is harvested from the fermentation broth and purified to pharmaceutical-grade quality for food manufacturing.
Integration
Ingredient for food makers
Perfect Day supplies ProFerm to food companies that incorporate it into sports drinks, protein powders, ice cream, and cheese products.
Perfect Day uses precision fermentation to produce real dairy proteins without animals. ProFerm, its flagship ingredient, is beta-lactoglobulin made from a genetically engineered fungus. Perfect Day supplies ProFerm to food and beverage companies for sports nutrition and dairy alternatives.
Raised $90M pre-Series E (Jan 2024); total $800M+ across 11 rounds.
ProFerm used in sports nutrition and dairy from General Mills, Nestlé, Mars.
With Zydus, building dairy protein facility in Gujarat, India; ops late 2026.
