Andreessen Horowitz has hired David Ulevitch as its newest general partner. Ulevitch is best known as the CEO of OpenDNS, which he sold to Cisco for $635 million in 2015. He stayed with Cisco for three years after the acquisition, but decided to stay on to help guide his team and technology. Now, he says he's particularly interested in how AI can change enterprise software. When Martin Casado first pitched David Ulevitch on the prospect of joining Andreessen Horowitz — one of Silicon Valley's premier venture firms, where Casado is a general partner — he got an unexpected response.
