Calendly, who's CEO is black, and is one of the top performing black led tech startups curiously doesn't have an about us page (and though I don't know the exact reason, I can only suspect why).
A very good friend of mine, a black woman in finance, had to have drinks with and entertain obnoxiously racist jokes from a potential white client to close the deal.
Black folks don't get the presumption of competence. You're assumed to be mediocre (or worse) until you can prove yourself exceptional.
