Colalife is my favorite startup

Most companies try to do too much and fail. One of the most awesome examples I have seen for solving a huge problem and making it work is Colalife.
By packaging their zinc medicine where it fits into a coke carton, ColaLife solved global distribution.

The punchline is that they were able to take on child mortality in Africa by identifying a distribution route for medicine that everyone has - Coca Cola - and then work both at the macro level and the micro (community) level to test their concept and grow it. By selling Zinc pills distributed through efficient local chains, they can actually impact the highest risk of death for children.
