Nathan Cohen-Fournier
Co-founder, Estuaire
Nathan has worked in the social economy and social finance sectors for over 12 years. From early 2023, he developed his own practice with a range of partners in both social finance and First Nations and Inuit economic development. He specializes in designing, structuring, and launching impact investing funds in Quebec.
Nathan worked at Bombardier (corporate finance) before pivoting to socio-economic development. After completing his master’s degree, he joined Makivvik. Based in Kuujjuaq for three years, he supported collective projects across Nunavik. He later joined the Lucie & André Chagnon Foundation as head of social finance, where he managed a $200M mission-related investment portfolio.
Nathan holds a Master’s in International Affairs from Tufts University and a Bachelor’s in Finance from Concordia University. A Chartered Financial Analyst (CFA) charterholder, he teaches social economy at Université de Montréal and social finance at Concordia University. He is slowly completing a certificate in creative writing and loves to write in his spare time.
Always up for an outdoor adventure or a canoe-camping trip, he can often be found in a lake – winter and summer alike. He loves music and sings with the Kinor choir.
