In an industry under pressure to reduce emissions and improve sustainability, a Silicon Valley startup may be stirring the recipe for change. Savor, co-founded by Kathleen Alexander and Ian McKay, has secured $33 million in funding from Bill Gates’ Breakthrough Energy Ventures and Synthesis Capital to create butter and cooking fats without animals or plants—using carbon as a base. The company’s approach could reshape global food manufacturing and lessen agriculture’s heavy environmental toll.

Reinventing Butter to Fight Climate Change

Agriculture accounts for nearly one-third of global greenhouse gas emissions, and fats alone contribute about 7%. By producing butter and palm oil substitutes in the lab, Savor seeks to ease deforestation, reduce methane emissions, and free up farmland currently dedicated to feeding livestock. “We wanted to save the world,” says Alexander, reflecting the company’s dual ambition of environmental progress and culinary innovation.

The technology behind Savor isn’t entirely new—it builds upon nearly century-old German and American chemical methods that convert gas into edible fats. However, Savor’s key breakthrough lies in replicating the taste, melting point, and texture of traditional dairy fats. The startup’s products are reportedly chemically closer to cow butter than any vegan option currently available, a claim that could attract chefs and manufacturers eager for both flavor and sustainability.

From Lab Table to Fine Dining

Although Savor’s creations have yet to reach supermarket shelves, they’ve already debuted in Michelin-starred restaurants such as SingleThread in California and Dirt Candy in New York, where chefs praise the product’s superior taste and functionality. The company currently produces its fats in a 25,000-square-foot pilot facility in Illinois, though only about 1% of the site’s capacity is in use due to high operational costs.

To keep costs manageable, Savor focuses on partnering with culinary professionals and food brands, allowing its ingredients to feature in existing recipes and products. Alexander envisions collaborations with major players like Mondelez, potentially allowing consumers to one day enjoy “vegan Cadbury eggs featuring Savor ingredients.”

The Road to Commercialization

Despite promising science, scaling production remains a formidable challenge. High manufacturing costs, limited revenue streams, and a cautious investor climate—particularly after the overpromises of earlier alternative food startups—make fundraising difficult. Still, Savor’s business-to-business model may give it an advantage, positioning the company as a supplier to established food brands rather than a direct competitor in the consumer market.

Regulatory approval also looms large. The company holds a self-affirmed GRAS (Generally Recognized as Safe) status and anticipates a formal FDA “no questions” letter by 2026, clearing the way for commercial distribution later in the decade.

A Measured Path Forward

Experts caution that replicating the nutritional complexity of plant-based oils remains difficult, though Savor’s founders argue that the environmental gains far outweigh such limitations. If successful, their innovation could redefine the global fats industry, transforming how food is made, transported, and consumed.

The next few years will determine whether Savor’s lab-grown butter can scale efficiently enough to compete with traditional dairy and plant-based alternatives. If it can deliver on price, health, and climate goals, the company might not just reinvent butter—it could reshape the future of sustainable food itself.
