David Selinger is a technologist at heart and has founded a number of successful start-ups, including Redfin and RichRelevance (and some unsuccessful ones too!). He has served a number of nonprofits including My Two Front Teeth (now the Family Giving Tree), the Darfur Stoves Project (now Potential Energy) and Silicon Climate. His favorite technology right now is deep learning, specifically as applied to image and video object detection/recognition. David believes that this technology is undergoing a disruptive improvement and will change numerous industries. That’s why he started Deep Sentinel—which puts deep learning to practical use protecting families and businesses.
