After searching for high-quality math supplements for his own daughter, Packard wrote a business plan to create an entire school online. He began securing capital, including $10 million from Milken and Oracle CEO Larry Ellison. By 2001, he had raised $41 million from individual investors and begun serving children in Pennsylvania and Colorado through K12, a virtual public school. The firm expanded; it provides materials and tutoring, a private online academy, and programs for individual public school districts. K12, which went public in December 2007, now has 900 employees serving over 50,000 students in 21 states.
