Sarbah was partly inspired by a course he took last year, “Contemporary Developing Countries: Entrepreneurial Solutions to Intractable Problems,” with Harvard Business School Professor Tarun Khanna. In it, Sarbah and Colom developed the initial business plan for their venture, bringing together an interdisciplinary mix of Harvard students to think about economic and social problems in developing countries and identify potential solutions.

“The class tried to see social problems from different lenses,” Sarbah said. “One week we would have a module on how would [an urban] planner look at  problem. Another week we would have a module on how a scientist or engineer would look at this problem. That really helped me understand the issue — not only from my perspective as a Ghanaian, but all these other perspectives.”

Sarbah and Colom are currently refining their business plan, discussing partnerships with universities in Ghana and overseas, and seeking funding. If the venture takes off, they expect to live in the U.S. and Ghana, but do a lot of traveling back and forth between Ghana and the U.S., taking advantage of networking opportunities in both countries.

Sarbah’s journey to Harvard from Yeji, the rural town in Ghana’s Bono East region where he was born, was a long one. Growing up, he shared a home with seven other family members but no electricity. For drinking and bathing water, he walked three miles to Lake Volta. Sarbah one of a few students from his high school to attend the University of Ghana. He remembers long nights studying by kerosene lamps. “Sometimes the smoke from that would make your eyes red and teary,” he said. But he persisted, and through education he’s been able to traverse the globe, earning degrees from the University of Ghana, Columbia University, and the University of Cambridge.

But home and helping others like himself have always held his heart and interest. One of the most satisfying ways he’s nourished that calling has been through EdAcme, the advisory service he runs that provides mentorship, coaching, admissions advice, and leadership and professional training to students from developing countries. Students he’s worked with have been accepted to a number of schools, including Columbia University, the University of Cambridge, and the University of Tokyo. Sarbah plans to continue that work as he attempts to launch his new venture. He also plans to continue speaking engagements and serving as an adviser or consultant to institutions and governments on social innovation and entrepreneurship, policy, and business issues.

“In many ways,” he said, “my satisfaction comes from helping people, especially young people, maximize their potentials. I think we all have a purpose for being on this planet. It’s important that we spend our energies on making the world better.”
