Y Combinator has hired its first black partner to aid in the drive to recruit more minority entrepreneurs. Prominent Silicon Valley entrepreneur Michael Seibel is joining as a full-time partner to coach high-tech hopefuls, according to a report in USA Today. A key part of his mission will be reaching out to black and Hispanics who are underrepresented in Y Combinator and more broadly in Silicion Valley. Y Combinator is Silicon Valley’s most famous – and most influential – incubator, graduating companies such as Airbnb and Dropbox that have grown into household names. Entrepreneurs who go through the start-up boot camp gain access to money and advice from some of the industry’s most powerful players and get coverage from technology blogs, a major advantage in an increasingly crowded marketplace.
