Allbirds founders Brown, a former professional soccer player, and Zwillinger, a clean-tech engineer, are on a mission to change the world’s carbon footprint, one cushiony pair of shoes at a time. The duo emphasize the sustainability of the product, constructed from natural materials like merino wool and eucalyptus fiber. They want the larger shoe industry, with its polluting and wasteful manufacturing processes, to follow their lead. Allbirds was profitable in its first year of operation, and three years later it has an estimated value of $1.4 billion. Its most recent $50 million round of funding paves the way for more retail locations and a launch in China.
