Unicorns (companies valued at over $1bn) often present some of the best opportunities to make a big buck – particularly if investors get in early enough, that is. Venture capitalists spend vast amounts of resources on trying to figure out the magic ingredients that differentiate the unicorns of tomorrow from the flops, though this becomes increasingly close to impossible the earlier one looks along the path from zero to hero. It is nonetheless curious to look at where they start: in particular, the university dormitories in which many of today’s biggest companies were dreamt up. It’s no surprise that Harvard comes second on the list (although one of its best-known future billionaires, Mark Zuckerberg, famously didn’t graduate). But top of the list is Stanford University, counting a huge 51 unicorn founders as alumni. Skulking around Stanford’s halls, a very lucky investor might have once been tipped to look out for, say, Sergey Brin and Larry Page (who went on to found Google), Evan Spiegel (Snapchat) or Elon Musk (Tesla).
