# The 47 largest franchise networks in Illinois

Tamtam tracks 47 franchise networks headquartered in Illinois. This list ranks all of them by number of employees on LinkedIn, led by McDonald's, Hyatt and Ace Hardware Corporation. Their median headcount is 518. Half of them were founded in 1997 or later. The most common headquarters are Chicago (15), Schaumburg (4) and Arlington Heights (2).

These Illinois-based franchise networks are primarily large groups and established mid-sized firms, with a focus on retail, hospitality, and food service. Notable examples include McDonald's, a global fast-food chain with over 37,000 locations, and Hyatt, which manages luxury hotels and resorts worldwide. Ace Hardware Corporation operates 5,500 stores in 70 countries, while IGA, INC. supports independent grocers. BrightStar Care offers healthcare staffing and homecare services, and @properties is a leading real estate brokerage in Illinois.

A significant pattern in this data is the strong concentration of headquarters in Chicago, indicating its role as a central hub for franchise operations within Illinois. The companies listed also span a broad range of founding dates, from Ace Hardware (1924) and IGA (1926) to more recent firms like @properties (2000) and BrightStar Care (2002), showing a mix of long-standing enterprises and newer ventures.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
