Qwiki

TechCrunch Disrupt $50,000 Grand Prize Winner

Qwiki is like Douglas Adams’ Hitchhiker’s Guide to the Galaxy come to life: type in a topic — any topic — and you’ll get a narrated, multimedia tour of the subject. Co-founder Doug Imbruce sums it up well: “We think in the future information becomes an experience that you watch,” he says. “Today, everyone is absolutely overwhelmed with information. We need to simplify.”

Imbruce uses Qwiki as his alarm clock, waking up each day to a pleasantly intoned run-through of his e-mail inbox, the weather and upcoming events. (One Startup Battlefield judge dubbed the system “your personal HAL.”) The site’s visual interface is its most obvious breakthrough: “It’s amazing to see a product that’s in beta have so much attention to the product design,” judge and Twitter product head Jason Goldman said. TechCrunch founder Michael Arrington dubbed it “the sexy Ferrari with absolutely no promises of launching.”
