How can philanthropies most effectively invest in leaders? While investing in talented individuals has great potential to impact the community, investing in an interconnected cohort of leaders can be transformative. Over the last two decades, numerous Jewish foundations and philanthropies have sought to further their missions by supporting fellowship grants, which help the greater community by empowering select individuals to become communal agents of change. Alumni of these fellowships have played a major role in the renaissance of Jewish life and the emergence of an entire sector of innovative Jewish organizations.
