Here we get to another unfortunate quirk around bias. Because the majority of founders are technical, it is technical skills that are most highly rewarded. The folks who build the machinery that makes money are paid much more handsomely than the folks who hold customers’ hands and rescue the business relationship when it all breaks down.
An unfortunate quirk of this model is that VC’s are overwhelmingly male and quite often white. The resulting mix of founders reflects a similar bias. People bet on those they understand, along with those who remind them of themselves, or of other successes in the technology industry. This is euphemistically termed pattern matching.
