A decade ago, when I first heard the term “B Corp”—a designation for companies that commit to pursuing not just profits but also purpose—I was skeptical. At the time, I was CFO of Cabot Creamery, one of the largest dairy cooperatives in the United States, and a great many questions ran through my head: Was this just another certification—like the Real milk seal and the Real Vermont seal that we’d already earned? Would the customers who bought our cheese and other products really care about this new label? What kind of burden would it place on our farmers, who, owing to our cooperative structure, were also our shareholders? How much work would it create for employees? How much would it cost us—up front and on an annual basis? And why on earth was it called a B Corp when it could be an A? That made the whole thing sound second-rate.
