We love entrepreneurs who are trying to change the world, make it a better place while making money.  Opara from Brazil are a great example.   They were one of the finalists in SmartCamp Rio prior to being accepted to Startupbootcamp Dublin.  Their solution is ambitious.  50% of all fruit in the developing markets is lost and they are tackling that problem.  As a side benefit they are providing tracebility across the entire supply chain. Here is their short video from Demo Day.
