This article looks at only founding teams which get the vast majority of equity. The study found that while less than 1 percent of venture-capital-backed company founders were African American and 12 percent were Asian, 83 percent had a racial composition that was entirely Caucasian.[1] The study mentioned was done by CB Insight from 2010.[2]
This lack of diversity in the founders that receive VC funding may not be that surprising given the lack of diversity of the investors making those choices.[3] And it's not too hard to find other sources that say there is a lack of diversity at the top.[4]
