Could you please link the study you are citing from? I'd be curious how it'd look after being equity adjusted.
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]
