Meet the world's top 15 unicorn hunters: These funds are backing dozens of booming startups

China's Tencent has 40 unicorns in its portfolio with a cumulative value of $177 billion including Epic Games and Ola.

Japan's SoftBank — a major investor in WeWork and Uber — has the most valuable portfolio as it continues to pump Saudi Arabian money into the world's most exciting companies. (Almost half of its $93 billion Vision Fund was funded by the kingdom.)

Despite having the most unicorns in its portfolio, Tiger Global's companies are cumulatively worth 45% less than SoftBank's portfolio which is worth a massive $389 billion. Intriguingly, Softbank has backed the most unicorns which come from outside the US and China — 18 — with the vast majority coming from the world's two largest economies.

"It's our job as venture capitalists to stand out and show them [potential unicorns] how we roll up our sleeves to support them as much as we can," said Lixandru. "I have been known to travel to Eastern Europe, Israel, and the US to successfully convince an entrepreneur to work with us. Now, I'm happy I did!"

In 12th is SV Angel. The fund has backed the most unicorns from either seed or series A funding on the list, making it a key talent spotter.
