Steven Rosenblatt's background spans three distinct tech eras—mobile ads at Quattro, Apple's iAd under Steve Jobs, and Foursquare's shift from a consumer app into an enterprise location-data company—giving him firsthand experience with how businesses turn user adoption into real revenue. He invests based on non-consensus judgment, backing founders before success is obvious, and he's known for favoring complementary co-founding teams over a single "hero founder," all while being recognized as a longtime fixture of the New York tech scene going back to one of a16z's first checks in the city.
