Mariame McIntosh Robinson is a global leader at the intersection of finance, strategy, and human capital development, with over twenty-five years of experience driving business transformation across the United States and the Caribbean. A former McKinsey and Bain & Company consultant, Rhodes Scholar, and engineer by training, she brings a rare combination of analytical rigor, operational leadership, and long-term commitment to helping founders, families, and institutions reach their full potential.
She is the Founder and Managing Director of Global Triangle Advisors (GTA), a US-based firm dedicated to unlocking the potential of founders, rising leaders, and family-owned businesses — helping them achieve transformative results through strategy, business transformation, and capital readiness. GTA serves clients across the USA and the Caribbean, with a particular focus on those at inflection points: scaling, professionalizing, or preparing for the next generation of leadership.
She founded GTA following an executive role at an early-stage fintech firm in the United States, and prior to that, seven years as President & CEO of First Global Bank in Jamaica — where she led a transformation that more than doubled profits within the first three years.
Before her banking career, Mariame spent seven years at the Caribbean's largest private equity firm, where she invested in and helped transform businesses across the region. Combined with her earlier consulting career — beginning at McKinsey & Company before business school and continuing post-MBA as a Manager at Bain & Company for four and a half years — this represents nearly two decades of advising, investing in, and transforming businesses across the Caribbean and the United States.
Mariame currently serves on the boards of Sygnus, a pan-regional alternative asset manager; Wigton Energy, a publicly listed Caribbean renewable energy producer; and the Caribbean Catastrophe Risk Insurance Facility (CCRIF) — the world's first regional parametric insurance mechanism, serving 23 Caribbean and Central American governments to provide rapid financial relief following natural disasters. She has previously served on the boards of Parkland Corp, a publicly listed company, through its acquisition by Sunoco, and Digicel Group.
Driven by a deep belief that human capital is the foundation of economic success, Mariame is the co-Founder and Chairperson of TEACH Caribbean, an educational charity founded by Jamaican Rhodes Scholars, and co-Founder of iamtheCODE Caribbean, a digital skills initiative aimed at expanding technology access and capability across the region.
She is a member of the Young Presidents' Organization (YPO) and the International Women's Forum (IWF), and was named a Young Global Leader by the World Economic Forum in 2014. She serves as National Secretary for the Jamaica Rhodes Scholarship.
Mariame holds a BSc. in Electrical Engineering from the Massachusetts Institute of Technology, an MBA from Harvard Business School, and an M.Phil. in Economics from Oxford University, which she attended as the 1998 Jamaica Rhodes Scholar.
