The following thesis explores the field of cross-sector partnerships between the for-profit and non-profit sectors. Two case studies were completed, including an interview with the ARAMARK corporation and the Children's Museum of Denver. Common themes and findings occurred throughout both interviews. It was emphasized that corporations choose their nonprofit partners based on their overall capacity to build a meaningful and long-term relationship, as well as whether the nonprofit aligns with their priorities as a corporation. The other deciding factor in many cases revolves around whether either party's customers or constituents might find the partner's services or products controversial in any way. Corporations want their partnerships to be strategic and meaningful resulting in a relationship that pleases and engages their employees and customers, as well as the media. Corporations also expect nonprofits that approach them are prepared and can clearly illustrate what the corporation's return on investment will be. Nonprofits must make a strong, solid case that proves how the corporation will benefit from a cross sector partnership.
