Not according to YC’s own website [1]. YC’s average deal size is 150k. In order for YC to burn 135m they would have to invest in ~900 different companies compared to Softbanks one bet on robotic pizzas. Investing in 900 different companies is a much more diverse portfolio and an entirely different value proposition.

If you want to cheer on the intelligence of Softbank because they lucked out with an investment in Alibaba early on, you must still hold stock in Yahoo!...
