B Lab is a non-profit organization that was founded in 2006 in Berwyn, Pennsylvania, by Andrew Kassoy, Jay Coen Gilbert and Bart Houlahan.

[2][3] The "B" stands for beneficial[4] and indicates that the certified organizations voluntarily meet certain standards of transparency, accountability, sustainability, and performance, with an aim to create value for society, not just for traditional stakeholders such as the shareholders.

[6] With its rigorous standards, B Corp certification can enhance a company's reputation, as well as attract socially and environmentally conscious customers.

[8] In addition to awarding B Corporation certifications to companies that score high enough on the B Impact Assessment, B Lab’s initiatives include administration of the B Impact Management programs and software, as well as advocacy for the adoption and improvement of benefit corporation statutes at the state level.

[13] B Lab has established a partnership with the United Nations to help the private sector translate the Sustainable Development Goals (SDG) into practical business processes.
