What Ülemiste City does

Ülemiste City is a mixed-use business campus spanning approximately 30 hectares near Tallinn Airport in Estonia, developed and operated by Mainor Ülemiste AS (a subsidiary of Mainor AS). The platform combines commercial real estate leasing with an integrated ecosystem of services, housing approximately 400 companies, 18,000 talents representing 73 nationalities, and 20+ university partnerships. Core physical assets include 78,000+ m² of directly managed office space across LEED Gold and Platinum-certified buildings (notably Alma Tomingas, Viktor Palm, and the Technopolis Ülemiste portfolio acquired in February 2024), three Health Centres (Tervisemaja 1-3), educational facilities, residential components, conference and community spaces, and mobility infrastructure connected to Rail Baltica.

The technology stack centers on a smart-city layer combining green building certifications, AI-based energy management (R8 Technologies' predictive digital operator), EV charging (eTerminal), smart parking, and the Test City platform, which provides real-world urban infrastructure, talent access and data for technology pilots (Skeleton Technologies supercapacitors, DPD/Clevon autonomous delivery, Grab2Go autonomous retail, Fyma computer-vision mobility analytics). The business model is primarily subscription/recurring through multi-year B2B office leases with direct enterprise sales, supplemented by ancillary service fees (healthcare tenants, education, Conference Centre, childcare, Green City services) and Test City program revenue. The stated €2.5 billion annual turnover refers to the combined revenue of tenant companies operating on campus, not Mainor Ülemiste AS's own revenue.

Broad incumbents

• Lendlease Corporation: Australian multinational real estate and infrastructure group developing mixed-use urban precincts and integrated communities globally. Comparable for its integrated mixed-use development approach, though operates globally rather than focusing on a single Nordic campus.
• Fabege AB: Swedish real estate company focused on prime office properties in Stockholm. Comparable for Nordic office property ownership and management expertise, though operates in a single metropolitan market rather than developing mixed-use campus ecosystems.
• Skanska AB: Swedish construction and real estate development company that develops office buildings and mixed-use properties across the Nordics. Comparable in scale and Nordic geographic focus, though Skanska operates broadly across multiple property types and geographies rather than concentrating on campus ecosystems.
• NCC AB: Swedish construction and real estate development company building office properties and mixed-use developments in the Nordics. Comparable for its Nordic real estate development activities and commercial property expertise, though operating more broadly than campus-specific developments.
• YIT Corporation: Finnish construction and real estate developer active in residential, commercial, and infrastructure projects across the Nordics and Baltics. Comparable for its Nordic/Baltic geographic footprint and real estate development capabilities, though broader in scope than Ülemiste City's campus focus.
• Castellum AB: Swedish commercial real estate company owning and developing office, logistics, and retail properties across Sweden, Denmark, and Finland. Comparable for Nordic commercial real estate portfolio management, though operates as a portfolio owner rather than integrated campus developer.

Direct peers

• Technopolis Plc: Finnish business campus operator that develops and leases office space across the Nordic and Baltic region. Most directly comparable to Ülemiste City given the similar campus-based business model and geographic overlap; the two companies previously competed in Tallinn before Mainor Ülemiste acquired a 51% stake in Technopolis Ülemiste in February 2024.
