Perfect Day

What Perfect Day does

Perfect Day, Inc., founded in 2014 and headquartered in Berkeley, California, is a food technology company that produces animal-free dairy proteins — specifically whey and casein — through precision fermentation using engineered microorganisms. The company's core technology replicates the functional and nutritional properties of conventional dairy proteins without any animal involvement, with disclosed lifecycle emissions 91-97% lower than conventional dairy. Its primary product is ProFerm, a premium B2B protein ingredient sold to food and beverage manufacturers for use in products such as ice cream, cream cheese, yogurt, and other dairy applications. The company complements its ingredient business with consumer-facing sub-brands, including Modern Kitchen (animal-free cream cheese and dairy products) and embedded partnerships with CPG brands such as Unilever's Breyers lactose-free ice cream. The underlying infrastructure is branded as the nth Bio platform, a biological engineering stack that also supports enterprise biology services for supply chain innovation.

The company monetizes primarily through transaction-based B2B ingredient sales (ProFerm) to enterprise food manufacturers, supplemented by consumer product revenue from its own sub-brands and recurring enterprise biology services. Pricing is quote-based and not publicly disclosed, consistent with large-volume industrial contracts. Perfect Day holds 25+ patent families around precision fermentation processes and has shipped over 50 million servings of animal-free dairy protein at commercial scale. Customers include global CPG enterprises (Unilever) and the company's own consumer brand Modern Kitchen, with a pharmaceutical-grade ingredient vertical added through its Sterling Biotech acquisition in India.

Perfect Day's strategic posture has shifted from a pure-play ingredient supplier toward a vertically integrated, multi-region producer. In November 2022 it acquired Sterling Biotech Limited through an NCLT-approved liquidation, doubling manufacturing capacity and adding pharma-grade capabilities. In August 2024 it sold a 50% stake in Sterling Biotech to Zydus Lifesciences for ~$66M, forming a 50/50 joint venture. A new precision fermentation plant in Gujarat, India is on track to begin operations in late 2026 with expansion in 2027, producing recombinant whey including beta-lactoglobulin for performance nutrition and dairy alternatives. The company has raised over $825M in disclosed funding from investors including Horizons Ventures, Temasek, CPP Investments, and Coatue Management.

Core offering

Perfect Day produces animal-free dairy proteins (whey and casein) using precision fermentation technology, bioidentical to conventional dairy proteins. The company sells ProFerm as a B2B ingredient to food and beverage manufacturers and also operates consumer-facing sub-brands such as Modern Kitchen that feature animal-free dairy products like cream cheese.

Product overview

Perfect Day operates as a food technology company utilizing precision fermentation to produce animal-free dairy proteins. The company's product portfolio centers on ProFerm, a premium animal-free protein ingredient that enables food manufacturers to create sustainable dairy products without animal production. Perfect Day has scaled to commercial production with over 50 million servings shipped, offering its proteins through consumer brands and B2B ingredient sales. The portfolio includes consumer-facing sub-brands like Modern Kitchen featuring animal-free dairy products, while the nth Bio platform represents the underlying biological engineering infrastructure powering ingredient innovation and supply chain solutions. The company expanded its manufacturing capacity through the acquisition of Sterling Biotech in India, with a new Gujarat facility targeting late 2026 operations to produce recombinant whey proteins including beta-lactoglobulin (BLG) for performance nutrition and dairy alternative applications.
