Jason Calacanis is a recognized voice in Silicon Valley. Besides being a successful entrepreneur and host of the very popular "This Week in Startups," he's one of the world's most famous angel investors.
And in his new book, "Angel" (available July 16) he says Silicon Valley is the only place to be if you want to be a top founder or investor.
Now, Mr. Calacanis certainly knows his stuff when it comes to making successful investments in unheard-of tech companies. Most notably he invested $25,000 in Uber when it was only worth $5 million. This was back in 2010, when Uber was only operating in one city, and only had a couple of Lincoln Town Cars. Today it's worth around $70 billion in the private markets.
