Ben Pasternak's first app, the smartphone game Impossible Rush, counted over one million downloads. His latest idea, Flogg, is an amalgamation of Instagram and Ebay. Users can share images of items over the Flogg social network. Friends can then make offers and purchase them, if they wish. Ben Pasternak has already raised several million US dollars in venture capital. Investors are hoping Flogg will be the next really big thing.
