B Corp Month

March is B Corp month, a global celebration of businesses that meet the highest standards of social and environmental performance, accountability, and transparency.

This year’s theme is Gen B: Whether young or old, big or small, Certified B Corps think boldly, act for change, and demand a better future. Our certification is more than a mark: it’s a way of seeing the world—and leading for good.

Check out our B Corp page to watch a series of videos where we share what it means to us to be a B Corp and how we’re working towards a better world.
