One in eight people on the planet lives in an Indian village. That's 775 million people, about half of whom live on less than $1 per day.

To Drishtee and its founder, Satyan Mishra, these numbers aren't daunting; rather, they represent an incredible opportunity. Drishtee is franchisor that helps Indian entrepreneurs set up internet-enabled kiosks to provide basic services in their villages. (Full disclosure: Drishtee is an Acumen Fund investee; I work for Acumen Fund.)

Since 2000, Drishtee's network has grown to encompass nearly 1,900 villages, bringing goods and services to about 2 million customers.

Tendai used to be a teacher in his native Zimbabwe, until he saw one of his students died for reasons related to poor water quality. That event changed his life's direction and led him to become one of the founding members of Pump Aid, an NGO that has brought safe drinking water to thousands of villages in Africa by designing and manufacturing Elephant Pumps based on a centuries-old Chinese technology.

Pump Aid is experiencing an interesting transition that explains Tendai's presence at this year's GSBI. In the midst of the difficult and unstable situation in Zimbabwe, it recently re-located to Malawi where the elephant pump has been very successful since its introduction as a pilot project a few years ago. It has also experienced growing demand from households and is moving towards creating a fee-based social enterprise called WISH (Water, Irrigation, Sanitation and Hygiene) that will partner with microfinance institutions to offer the "WISH Package", a comprehensive solution for clusters of households that incorporates clean water (through the Elephant Pump), sanitation (through the Elephant Toilet) and nutrition (through nutrition gardens).

So here is Tendai, whose next steps I look forward to tracking and sharing through NextBillion.net.
