Rainbo is B-Corp Certified

We envision a global economy that uses business as a force for good. This economy is comprised of a new type of corporation – the B Corporation – which is purpose-driven and creates benefit for all stakeholders, not just shareholders. 

As Certified B Corporations and leaders of this emerging economy, we believe:

  • That we must be the change we seek in the world.
  • That all business ought to be conducted as if people and place mattered.
  • That, through their products, practices, and profits, businesses should aspire to do no harm and benefit all.
  • To do so requires that we act with the understanding that we are each dependent upon another and thus responsible for each other and future generations.
