Marcy Twete, Managing Director, Market Development


Marcy Twete is a recognized leader in corporate responsibility and sustainability for multinational Fortune 500 companies. She believes (to tweak a quote from Former President Bill Clinton) there is nothing wrong with corporate America that cannot be cured by what is right with corporate America.

Marcy joined social sector data and insights leader Mission Measurement in 2018 as Managing Director, overseeing market development for the company’s patent-pending Impact Genome Project®, enabling social impact investors to better measure the impact of community investment programming through an evidence based, data-driven approach to outcomes evaluation.

Prior to joining Mission Measurement, Marcy led sustainability and corporate responsibility at ArcelorMittal, the world’s largest steel and mining company. There, she led a team responsible for developing the first Integrated Report in the steel industry in the Western Hemisphere, and was part of the global team responsible for creating ArcelorMittal’s sustainability initiative centered around its 10 sustainable development outcomes.

Marcy’s background also includes nearly a decade in the nonprofit sector leading and advising annual and capital campaigns ranging from $3 million to $4 billion. Following her work in women’s organizations, she also founded a women’s career development initiative that attracted more than 1 million women to its services from 2012-2014 and is the author of the book You Know Everybody! A Career Girl’s Guide to Building a Network That Works.

Marcy is a proud Trustee at the Chicago Architecture Center. She received her undergraduate degree in Political Science from the College of Saint Benedict and her MBA from Kellogg School of Management at Northwestern University.
