Founded by John and Maury Leyland Penno and led by CEO Ross Milne, Leaft Foods exists to reduce the environmental impact of food production. Leaft has developed a novel method to extract Rubisco, the world’s most abundant protein source found in leafy greens, into a highly digestible form for human consumption. Protein is a vital nutrient in everyone's diet, and with the global population expanding, Leaft is well-positioned to meet this nutritional demand.

Rubisco can also be sustainably grown with a significantly lower carbon footprint compared to other protein sources like beef and dairy. Recent modelling indicates that producing Rubisco protein directly from leafy crops results in a carbon footprint per hectare that is 10 times lower than conventional dairy protein. Furthermore, Leaft's protein extract contains several advantageous attributes including no grittiness, complete nutrition profile and no known allergens. These make Rubisco ideal for multiple commercial applications ranging from use as a food ingredient in various formulations to serving as a nutrient dense sports supplement.
