The Kauffman Foundation is clearly the most entrepreneurial philanthropy. Their deep understanding of the importance of entrepreneurship to job creation and economic vitality is, unfortunately, unique in philanthropy and public policy.
High Tech High, San Diego, is my favorite school because it encourages kids to explore and create—preparing them for the world to come. They formed their own graduate school to certify teachers and offer them extended learning opportunities.
If you put these two ideas together, you can begin to imagine a new generation of business schools that are formed around entrepreneurial activity supported by venture and philanthropic investment. Like HTH Grad School, it would be 80% practicum—learning by failing (and occasionally succeeding).
