19-year-old entrepreneur Cory Levy is trying to solve a problem. He believes that we miss millions of opportunities to meet like-minded people because we don't have any knowledge of the people around us. There could be people within feet of you at a coffee shop, office building or bar who share friends, interests and professional connections, but we may never realize this in the physical world. To fix this, Levy wants to give people knowledge of who and what is around us. Today, Levy and his co-founder Michael Callahan are debuting One, a mobile app that notifies you when there are people around you that share your interests. One already has an all-star group of backers, who have put over $1 million in seed funding in the startup. Investors include SV Angel, Keith Rabois, Gary Vaynerchuk, Naval Ravikant, Michael Dearing, True Ventures, Charles River Ventures, and General Catalyst.
