Here are the hot areas in tech where a top VC firm wants to focus its new 1.5 billion fund

"Software eating the world" is the basic philosophy behind all of Andreessen Horowitz's investments. But the Silicon Valley VC firm has a few specific areas of tech that are lighting up its radar right now. With 1.5 billion in a new fund to invest in startups, managing partner Scott Kupor told Business Insider about a few areas that the firm is super excited about: While Kupor called out these four areas specifically, it doesn't mean that the firm is not interested in any company that falls outside the categories. The firm is still looking for entrepreneurs with big ideas that have the software to back it. "For us, we're always looking for companies where software is the differentiating factor of the business," Kupor said.
