What Chicago Sister Cities does

Chicago Sister Cities International (CSCI) is a non-profit organization founded in 1960 that manages Chicago's official relationships with 28 international sister cities spanning Europe, Asia, Africa, the Americas, and Oceania. Operating as a division of World Business Chicago, a public-private economic development partnership, CSCI advances citizen diplomacy through programs in cultural arts and tourism, global education, government relations, and international business. Its core programs include the Medical Initiative (partnering with Northwestern's Lurie Cancer Center), the Social Services Exchange Program, the Humanitarian Committee, the annual Unifest cultural celebration, the Délice Network gastronomic membership, and the Discover Our Sister Cities virtual speaker series. These programs are delivered through a governance structure of 29 volunteer committees (28 city-specific plus Humanitarian and Social Services) supported by over 600 active volunteers.

CSCI's revenue model is entirely donation- and sponsorship-based, with no commercial product or pricing structure. Income derives from individual donations (processed via PayPal), corporate sponsorship packages, and grant funding from institutional partners such as the Lynn Sage Cancer Research Foundation and Beltone. The organization maintains a small professional staff of approximately 6 people (Executive Vice President, Vice President, Director, Senior Program Manager, and two Program Managers) under the leadership of Executive Vice President Adrienne Tongate, with an advisory board drawn from firms including Heidrick & Struggles, Revieve, and Hinshaw & Culbertson. The organization has no proprietary technology stack, software products, or AI/ML capabilities; its digital footprint consists of a content website, email newsletter, and social media channels used for awareness and community engagement rather than commercial transactions.

CSCI operates under guidelines established by Sister Cities International, the national umbrella body, and holds quasi-official status conferred by mayoral-level agreements dating to the first Warsaw pact in 1960. Geopolitically, the organization suspended its Moscow relationship effective March 1, 2022, in response to the war in Ukraine. The 65th anniversary in 2025 is being actively leveraged for stakeholder engagement and brand reinforcement. As a civic diplomacy organization rather than a commercial enterprise, CSCI's competitive position rests on its unmatched 65-year track record, its volunteer-driven committee infrastructure, and its institutional embedding within World Business Chicago, rather than on financial growth metrics typically used to evaluate investment opportunities.
