What GOSB does

GOSB (Gebze Organize Sanayi Bölgesi) is a Turkish Organized Industrial Zone (OSB) established in 1986 in Gebze, Kocaeli, operating as a quasi-governmental industrial-zone management entity under Turkish OSB legislation. It manages a 518.34-hectare zone at 97% occupancy, hosting 178 active production companies (42 of them foreign-capital) and approximately 29,000 employees across the tenant base. Named tenants include Siemens, Alarko Carrier, and Agco. GOSB also operates GOSB Teknopark, a technology park subsidiary supporting R&D and technology tenants within the zone.

GOSB's core service portfolio covers infrastructure (utilities, roads), facilities management, licensing and permitting, transportation, social amenities, and shared industrial utilities. The technology backbone includes the GOSB Kule ve Veri Merkezi (an operator-independent, Tier III-compatible data center with A+B dual power supply and 8 kW-per-rack cabinet density), a 4,800 m³/day wastewater recovery facility, a continuous natural gas supply network (1 main station plus 8 district regulator stations serving the GOSB and TEMBELOVA regions), integrated waste segregation and recycling, and an energy management system. GOSB holds ISO 9001, 14001, 27001, 45001, and 50001 certifications, AFAD disaster-management accreditation, TSE-verified greenhouse gas reporting (cumulative -8.3 M tons CO₂e), and Green OSB certification from the Ministry of Industry and Technology.

Revenue derives from two streams: recurring service fees (Hizmet Bedelleri) charged annually to operating tenants for infrastructure, utilities, and administrative services, and one-time land lease and sale revenue from companies establishing operations in the zone. Pricing is not publicly disclosed. The go-to-market model is direct enterprise engagement with manufacturers seeking turnkey industrial infrastructure, supplemented by government and academic partnerships (World Bank, Akbank, Yıldız Technical University, Gedik University). Recent strategic activity has emphasized green-industrial positioning and international tenant diversification through diplomatic outreach to Senegal, Kazakhstan, and Uganda.
