My, how times have changed.

Five years ago, Eric Yuan, chief executive officer and founder of video conferencing company Zoom, was asked to deliver an insider's look at his business at the influential tech-savvy conference Montgomery Summit in Santa Monica.

Yuan did not end up giving his presentation at the Summit that year. At the time, Jamie Montgomery, who runs March Capital, the Santa Monica-based venture capital firm that invests in breakthrough technology companies in person, remembers his reaction, "What the hell is Zoom?"
