About the African Diaspora Investment Symposium

Past Barka Awards Winners​

The Barka Award honors a notable individual for their distinguished contributions to the African and African diaspora community.

The ADN Annual Barka Award is one of the African Diaspora Network’s highest honors, recognizing exceptional leadership, service, and long-standing commitment to Africa and its global diaspora. Rooted in the spirit of barka, a word meaning blessing and gratitude, the award celebrates individuals whose work has meaningfully advanced opportunity, dignity, and shared prosperity across communities. Each year, ADN spotlights leaders from the private sector, public service, philanthropy, civil society, and the global diaspora whose vision and actions exemplify values that move beyond remittances, toward transformational impact, institution-building, and long-term economic and social progress.

A Community of Distinguished Leaders

Past Barka Award winners represent a diverse and influential community of global changemakers, from entrepreneurs and investors to philanthropists, whose contributions have shaped ecosystems, influenced policy, mobilized capital, and inspired the next generation of leaders.

Through this award, ADN honors and elevates models of leadership that demonstrate what is possible when vision, responsibility, and diaspora engagement come together.

Sir Mo Ibrahim’s legacy as a visionary businessman and changemaker aligns with the very spirit of the Barka Award. As the founder of Celtel, he revolutionized telecommunications across Africa, bringing connectivity and opportunity to millions. Through the Mo Ibrahim Foundation and the Ibrahim Index of African Governance, he continues to set global standards for transparency, accountability, and principled leadership on the continent.

There are rare individuals whose commitment to the greater good extends far beyond obligation. Melissa Greer was one such person. An investor, entrepreneur, philanthropist, and community leader, Melissa was also, above all, a deeply present and generous friend. She made time for others, offered support readily, and gave with remarkable openness and sincerity. Everything she did was grounded in care and love. In 2016, Melissa became the lead sponsor of the inaugural African Diaspora Investment Symposium, helping to launch what has since become our signature convening. For years thereafter, she remained a steadfast supporter, annually hosting our ADIS speakers dinner as a way to personally thank those who shared their time and expertise. Melissa embodied generosity in its truest form, and her spirit continues to inspire us. She represents the very best of our shared humanity.
