Ritwik Pavan invented an app, VADE, that uses a network of sensors to tell drivers where open parking spaces are in realtime. He then realized there would be more money in selling the app to municipal governments for collecting data on parking and traffic patterns. Governments have traditionally contracted for case studies to gather that kind of information. Pavan and his peers hope to raise $240,00 this summer to set up a pilot system in one city, which would go live by the end of the year. Already, several North Carolina cities have expressed an interest in using VADE. Pavan went into business at age 16. As founder and CEO of Linker Logic Technologies, he works with a team of friends from high school to design apps for businesses and provide other web services like search engine optimization and social media management. The price for a typical Linker Logic app runs around $25,000-$100,000. Pavan was no novice when he went into business. He had developed two apps before, one of which was downloaded 500,000 times.
