Posse was founded in 1989 by
Deborah Bial, first partnering with
Vanderbilt University. After initially recruiting students solely from
New York City, the program has expanded to serve students from more than 20 U.S. cities. The foundation finds diverse groups of students with academic achievements and helps to recruit and enroll in top schools. The Posse Foundation's founder, Deborah Bial, received the
MacArthur "Genius" Grant in 2007 for her work with Posse. In March 2010, the Posse Foundation was one of ten organizations chosen by
President Barack Obama to receive a portion of his $1.4 million
Nobel Peace Prize award money. In 2021, Posse announced the launch of the Posse Arts Program, a new initiative with the stated goal of supporting students in creative arts, conceived in collaboration with
Lin-Manuel Miranda,
Luis A. Miranda Jr., and the Miranda Family Fund. ==Awards and grants==
