The CEO of one of America’s biggest brokerages is urging his firm’s agents to use their business spending to further racial equity.

Robert Reffkin took to CNBC and social media on June 8 to urge his company’s agents to take the “15 Percent Pledge,” a movement urging companies across America to dedicate a portion of their shelf space or vendor spending towards Black professionals or black-owned businesses.

The pledge, whose name refers to the share of America’s population that self-identifies as Black or African American, is intended to rectify longstanding gaps in family wealth and business ownership between white and Black Americans. Activists are also pressuring major retailers like Target to take the pledge and set aside shelf space for products from Black-owned businesses.

Real estate agents buy services from a range of vendors, from photographers to videographers to attorneys to contractors to home stagers. The pledge also can encompass the small businesses agents refer clients to.

Reffkin said Compass would also requiring that its external advisors, including lawyers, accountants, bankers, consultants and recruiting firms, have Black professionals on the teams directly advising the brokerage. Reffkin also called on other companies to diversify their boards and senior leadership ranks.

In an email to Compass employees, which he also posted to social media May 31, Reffkin, who is Black, said George Floyd’s death in police custody in Minneapolis left him “heartbroken.”

“In my life, I’ve tried to turn pain into positivity. Here, we need to turn pain into progress,” he wrote. “The Compass family is 20,000 strong. If we each turn our heartbreak into action in our communities, we can make a real difference in our country.”
