Mapping is a big boy's game, with Google Maps, Bing Maps, and MapQuest dominating maps on both the Web and mobile. But sometimes it takes a startup to push things forward. 3-D mobile mapping startup UpNext is hoping to get on the map, so to speak, with its detailed 3-D maps of cities and venues like the Super Bowl stadium. The New York city startup, which has been around since 2007, just raised a $557,000 angel round in a convertible note, according to an SEC filing . Investors include Chris Sacca's Lowercase Capital, David Cohen of TechStars (who invested individually), David Tisch and Oleg Tscheltzoff Co-founder Danny Moon says the company will use the funds to expand its platform from its own mobile and iPad apps to become an underpinning technology for "travel guides, resorts, event planners, amusement parks, to name a few," which can incorporate UpNext's 3D maps into their own apps.
