Christian Lanng is the 32-year-old CEO and co-founder of Tradeshift, a company that provides easy and free business network and payment solutions. Tradeshift was founded on the simple idea of reducing the inefficiencies of paper-based business processes like typing and retyping documents. In just 12 months, Tradeshift has grown significantly and is now used in 61 countries. Lanng advises entrepreneurs to build technology for the global market, do the hard work themselves as the greatest way to learn, and ignore advice that tells them their idea is wrong.
