Los Angeles-based social platform At the Pool wants you to make more friends. Not just online friends, but real friends. The startup provides an online community that connects like-minded, close-by people to one another, with the hope they will hang out in the real world. The invite-only, "exclusive community of extraordinary people" was funded with $1 million from some friends of its own, Clearstone Venture Partners and a flight of L.A. angel investors. The platform has expanded into more than 50 countries since being launched in July.
