Midwest Investors Diversity Initiative

Home / Financial Institutions / Equity, Diversity & Inclusion / Midwest Investors Diversity Initiative

The Midwest Investors Diversity Initiative (MIDI) is a coalition of institutional investors dedicated to increasing racial, ethnic, and gender diversity on corporate boards of companies headquartered in Midwestern states.


With over $820 billion in assets under management and advisement, the coalition uses corporate engagements and shareholder rights to protect shareholder value and maximize returns.

“We know that diversity is good for business. We also know that change is hard, especially inside our nation’s boardrooms. Many corporate leaders agree that diversity benefits their operations and board performance. Our focus is to help them navigate this change.”

What We Do

MIDI offers guidance and tools to help companies take steps to diversify their boards, working with company nominating and governance committees to:


  • Adopt a policy for the search and inclusion of minority and female board candidates
  • Require minority and female candidates to interview for every open board seat
  • Instruct third party search firms to include such candidates in the initial pool
  • Expand the candidate pool to include candidates from non-traditional sources

Since 2016, when the group was formed, MIDI has undertaken 75 company engagements. Among the companies engaged, 90 women and persons of color have received board appointments and 34 companies have adopted a diverse search policy. 


MIDI collaborates with and complements the work of the Thirty Percent Coalition, with the majority of its participants being active members. Founded in 2011, the Thirty Percent Coalition is a national organization advocating for diversity on corporate boards, promoting women and people of color. Representing more than $6 trillion in assets under management and one of its kind in the U.S., membership includes public companies, private equity, institutional investors, state treasurers, professional services firms and advocacy groups working together for the first time.
