<p>Crunchbase had an article of where startup founders went to college:
<a href="http://info.crunchbase.com/2013/08/entrepreneurs-and-universities/">http://info.crunchbase.com/2013/08/entrepreneurs-and-universities/</a></p>
<p>Unfortunately, they scrunch all degree types together (grad, undergrad, b-school, etc.), so Stanford and Harvard lead everyone, but I'd expect them to with their powerful b-schools and Stanford's prolific grad programs.</p>
<p>A more interesting question is where startup founders went for undergrad. Well, they have a dataset there, so I played with it, and excluding the grad schools, here is what I came up with for North American colleges (among the rest of the world, only some Israeli and maybe some Indian) ones would have made it in to the list, BTW):</p>
<p>All majors (minimum of 10):
Stanford: 92
Cal: 72
Harvard: 63
MIT: 54
UPenn: 48
Cornell, Yale: 40
Illinois: 34
USC: 33
UMich: 32
Columbia: 29
Brown: 25
Princeton: 23
Duke: 22
UT-Austin: 21
CMU: 20
UCLA: 18
NYU: 16
UDub: 15
Dartmouth, McGill: 14
UCSD, Georgetown, Maryland: 13
UW-Madison, Babson: 12
UVa, Syracuse: 11
Northwestern, Cal Poly SLO, RPI, Santa Clara, UChicago, UColorado, UFlorida, UNC-CH: 10</p>
<p>Notable: CalTech does not make the list (neither do JHU, Rice, WashU, & Vanderbilt).</p>
<p>CS only (minimum of 5)
Stanford: 36
MIT: 25
Illinois, Cal: 18
Harvard: 15
Cornell: 12
UPenn: 9
UMich, CMU, Columbia: 8
Maryland, Syracuse: 7
UT-Austin, Duke, Iowa: 5</p>
<p>Notable: UIUC CS and Cal CS (undergraduate) have almost as many startup founders as alums as the entire alumni base of Princeton/Duke/CMU (and more than Dartmouth/CalTech/UChicago/JHU/RiceWashU/Vandy)</p>
