# The 30 largest family-owned companies in Istanbul

Tamtam tracks 40 family-owned companies headquartered in Istanbul. This list ranks the 30 largest by number of employees on LinkedIn, led by Anadolu Group, Sabanci Holding and Yıldız Holding. Their median headcount is 719. Half of them were founded in 1970 or later.

These family-owned companies in Istanbul are predominantly large, diversified conglomerates with interests spanning multiple sectors. Companies like Anadolu Group, Sabanci Holding, and Yıldız Holding each employ tens of thousands of people and operate across various industries, including manufacturing, finance, energy, and retail. Many of these firms have a long history, with several founded in the mid-20th century, indicating established presences in the Turkish economy.

A significant pattern observed is the prevalence of holding companies and investment management firms, such as Akkök Holding and Zorlu Holding, which manage diverse portfolios. Manufacturing also features prominently, with companies like Eczacıbaşı Topluluğu and Evyap producing goods ranging from ceramics and personal care products to industrial materials. This mix reflects a broad industrial base within Istanbul's family-owned business landscape.

## 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 14, 2026.
