Mahanyele was born in Meadowlands, Soweto, South Africa. Her father, who died in 2012, grew up in a family of "10 or 11 siblings" and had to pay for his own schooling. Mahanyele's mother died when Phuti was 17-years-old. In a 2013 interview, she spoke of her parent's commitment to her and her sister having the best education possible and the expectation that she would work in a commercial environment. After her mother's early death at age 42, Mahanyele has said that it was a lesson to her not to take time for granted and that she does not understand when she sees people wasting time. Phuti Mahanyele left Johannesburg, South Africa at age 17 to attend Douglass College in the United States. She graduated with a Bachelor's degree in Economics in 1993. In 1996 she earned an MBA from De Montfort University. In 2008, Mahanyele completed Harvard University's Kennedy School of Governmentexecutive education program "Global Leadership and Public Policy for the 21st Century".
Career
Mahanyele joined Fieldstone Private Capital Group in New York City, an international investment banking firm specialising in infrastructure development. She eventually became vice president at Fieldstone in New York, and later transferred to the firm’s South African office. She then became head of Project Finance South Africa at the Development Bank of Southern Africa. Of her return to South Africa from a successful career in the United States, which some have seen as unusual, she said "where else in the world would it make sense for a black woman to be?" She joined Shanduka Energy in 2004 as managing director and later became chief executive officer of Shanduka Group which was founded and is chaired by South Africa's 2018 president-elect Cyril Ramaphosa. In 2016, Mahanyele resigned from Shanduka Group and started her own company, Sigma Capital.
Campaigning
In 2012, Mahanyele spoke to the Women's Leadership Conference, arguing that a greater role for women in business was necessary not only to rectify a social injustice but, more importantly, because there was "an economic and business imperative" to use the talents of women to solve the problems that the world faces. Mahanyele was selected as a Global Young Leader by the World Economic Forum in 2007. She is involved in the World Economic Forum's "Dignity Day" initiatives, and has been chairperson for Global Dignity for South Africa. At the U.S.-Africa Leaders Summit in Washington D.C. in 2014, Mahanyele was the only African woman on a panel for “Expanding Opportunities: The New Era For Business In Africa”, moderated by former U.S. President Bill Clinton. Mahanyele is a patron of NEET.
