These Philly colleges are breeding the most 'unicorns'

Scan a list of "unicorns" and you'll find that quite a few of their founders were educated in Philadelphia.

Elon Musk, the founder of SpaceX, Tesla Motors and Solar City, would be the best known. He earned undergraduate and graduate degrees from the same school.

A unicorn, of course, is a start-up company with a value of at least $1 billion. TechCrunch reported this month there are 208 unicorn companies with a total valuation of $761 billion.

Uber and airbnb are the two most valuable unicorns in the United States, at valuations of $62.5 billion and $30 billion, respectively.

The third company on that list is privately-held Palantir Technologies, a Silicon Valley software and services company specializing in big data analysis, with a $20.1 billion valuation. It was co-founded by Alexander Karp, 49, a Philadelphia native who took his undergraduate degree from a local school.

And four local grads are behind Warby-Parker, the billion-dollar company that makes eyewear for sale online, according to www.goodcall.com.

So, which Philly institution's alumni have produced the most unicorns?

Not much of a surprise there. The Wharton School at the University of Pennsylvania leads that list, with eight graduates behind four unicorns.

But the other local schools may surprise.

Drexel University has produced two graduates who went on to found unicorns, while Villanova University School of Law and Haverford College graduate founded one each. (Penn State University, while not a Philadelphia school has produced one, as well.)

Here's a list of the schools and their unicorn-founding alumni, according to goodcall.com:
