Saving the (developing) world, one (young) person at a time.

Sunit Shrestha, in his groundbreaking article, Young Development Innovators published at Beyond Tunis. Flightplan 1.5 of the Global Knowledge Partnership , wrote that

Young people understand the concept of social entrepreneurship almost immediately… Youth social enterprises led by young visionaries are a nascent force. Although small in numbers, the impact achieved by these enterprises on the ground has been quite impressive." 

He describes three such Gen-Y/Millennial youth programs: Digital Divide Data (DDD)  in Cambodia, Meal Exchange  in Canada, and TRN in Thailand.  These are only a few of the hundreds of such programs aimed at generating and training a new generation of social entrepreneurs.  I have listed below a few that I have worked with or know of directly:

• Think Impact:  connects American college students and recent graduates with rural villages in Africa to become social entrepreneurs
• Thnking beyond borders: helps gap-year youth to explore international development through global service learning and academic study.
• MBAs without Borders: Canadian organtization that empowers entrepreneurs by matching them with talented MBAs to build poverty-alleviating business solutions
• Global Citizen Year: a bridge year between high school and college that creates opportunities for youth to work as apprentices in Asia, Africa and Latin America
• Youth Venture of AShoka:  helps teams of people start new youth-led social entrepreneurial organizations. 
• New Profit Inc. invests in a  portfolio of innovative young social entrepreneurs to help them build organizations and scale their social impact.
• Coro.  Trains emerging young leaders in the US, including training in social entrepreneurism.

• US-Saudi -Women's Forum on Social Entrepreneurship:  connects women to business and social entrepreneurial skills in partner organizations

• New Leaders Council:  trains post-college youth in progressive leadership and social entrepreneurism

• Schwab Foundation for Social Entrepreneurship: does not give grants, but operates programs that connect young social entrepreneurs with resources and each other, like the Young Global Leaders
  

Along with the generating and training programs, many organizations have sprung up or expanded their programs to provide grants, logistics and other concrete resources for young people going into international social entrepreneurism.  In addition to our host, the Skoll Foundation, GenY/Millennial social entrepreneurs should explore:

• The Unreasonable Institute:  training and connection to startup capital

• Youthlearn:  small grants (US$500) to young social entrepreneurs
• DoSomething:  small grants (US$500) and other programs for youth social entrepreneurs
• Dell/University of Texas; $50,000 competitive grants for college student s who want to become global social entrepreneurs
• The Omidyar Network:  makes  market-based investments in organizations  with the potential for large-scale, catalytic impact.  Not strictly for young people, but an important resource for all social entrepreneurs. 

• Echoing Green: provides seed funding and support to young social entrepreneurs to launch organizations around the world.
• MARCsMovement: support for youth entrepreneurship organizations 

• Starbucks YouthActionNet and grants to young social entrepreneurs
• About Face International: provides a discussion area for youth social entrepreneurship
  

This a small sample of what is available.  Wikipedia lists many others here. Millennials should also get to know the Ashoka's Changemakers "open sourcing social solutions" initiative which uses an online platform for what it calls collaborative competitions to build communities of practice around pressing issues.
