Horowitz hosts an AMA on Product Hunt. On his mentors:
At this point in my life, I would probably refer to them as friends rather than mentors. Bill Campbell and Andy Grove are probably the two that I have learned the most from. Andy’s whole life is a great lesson in how I should live mine. The way that Bill listens to people is so advanced that I learn something every time I’m with him. There are other people on other fields. Like Nas. Nas has the ability to see the world in such a radically different perspective. We can listen to the same song and he’ll hear 30 things that I didn’t.
On a Silicon Valley bubble:
Having been CEO in 2001, I don’t think that we’re anywhere near where we were then. Valuations have gotten high in certain tech sectors in the private markets only, but they have actually corrected themselves pretty quickly. For example, enterprise software started to get over valued privately, but after several companies went public at lower valuations than their last private rounds, the private markets corrected as well. I don’t see a massive crash on the horizon like 2001. In 2001, Nasdaq lost 80% of its value. I’ll bet any bubble believer everything that I have that Nasdaq won’t drop 80% in the next 5 years.
