In 2016, Walker’s Bevel Trimmer got a major marketing push from brand ambassador-investor Nasir bin Olu Dara “Nas” Jones, an American hip hop recording artist, record producer, actor and entrepreneur,  Huffington Post reported.

Nas’ lyrics on the chorus of DJ Khaled’s single “Nas Album Done” underscored for Walker the company’s instinct to uplift and enrich black businesses, Walker told Huffington Post.

“By (Nas) saying ‘My signature fade with the Bevel blade,’ everybody knows about Nas’ haircuts. So for him giving us the cosign and taking responsibility for his lineup, that’s significant,” Walker said. “It’s not only significant, it’s authentic. It makes sense. And also, his message is celebrating black business and empowerment.”

After the song was released, the trimmer was named among GQ’s best grooming products of 2016.

“We’re thankful that we have the partners and investors to do stuff like that on our behalf without our knowing,” Walker said, “and we’re only gonna see more of that.”

Beyond knowing intuitively that diversity matters, it also affects the bottom line, according to McKinsey & Company, a New York City-based management consulting firm and analyst that evaluates management decisions in public and private sectors.

Companies in the top 25 percent for gender or racial and ethnic diversity are more likely to have financial returns above their national industry medians, McKinsey reported two years ago in its report, Diversity Matters. Companies in the bottom 25 percent are statistically less likely to achieve above-average returns.
