These Turkish foundations are primarily large organizations, many of which operate in the defense, aerospace, healthcare, and higher education sectors. Companies like Aselsan, founded in 1975, specialize in defense electronics, while Turkish Aerospace, established in 1973, focuses on aircraft and space systems. Medipol Healthcare Group, founded in 1997, is a private university hospital, and Baskent University, founded in 1993, provides higher education. VakıfBank, established in 1954, offers banking products and services.

A notable pattern among these foundations is the concentration of headquarters in two major cities. Istanbul hosts several, including VakıfBank, Medipol Healthcare Group, and Yeditepe University. Ankara is home to Turkish Aerospace, Baskent University, and Bilkent University, demonstrating a geographic clustering of these significant institutions.

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.
