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.
And to make this personal, feeling like you have to be the best in every group in order to be respected enough that you can't be ignored leads to overwork and burnout.
