What GEM Real Estate does
GEM Real Estate is a Netherlands-based independent developer and long-term investor specializing in logistics real estate. Founded by Willem Slager and operating as a strategic collaboration with Timeless Investments (the family office of the Van Veggel family), the company focuses on three integrated service lines: brownfield and greenfield development of future-proof warehouses, value-add investments that revitalize and upgrade existing logistics assets, and in-house asset management covering commercial, financial, and technical operations. Its investment profile targets sites above 20,000 m² for development and above 6,000 m² GLA for value-add assets, with a portfolio that spans Oosterhout, Rotterdam-Botlek, Moerdijk, Dordrecht, Veghel, and Oegstgeest.
The company's technology stack centers on its proprietary GEMSTONE redevelopment concept, which standardizes delivery to BREEAM Very Good to Excellent certification, all-electric systems, high insulation values, and Paris Proof performance standards. Operational technology includes digital monitoring and AI-driven data analysis tools used to track building usage and energy performance across the asset lifecycle, enabling proactive management and ESG reporting. Underlying engineering emphasizes brownfield redevelopment — reusing existing infrastructure (electricity, water, data, transport links) and upgrading with solar panels, green energy systems, and digital infrastructure.
GEM makes money through a combination of recurring rental income from long-term leases with institutional logistics tenants (e.g., SolaX Power Netherlands, Rietveld Logistics Group) and one-time returns from the development, repositioning, and eventual sale of logistics assets. The company pursues off-market acquisitions via direct outreach to property owners and through a network of commercial advisors, and co-invests alongside institutional capital — notably through a joint value-add logistics platform with Tristan Capital Partners using the EPISO 6 fund. GTM motion is relationship-driven, B2B enterprise sales with bespoke deal-by-deal pricing and multi-year lease or co-investment contracts.

Revenue model
- Real Estate Development & Asset Disposition: GEM develops logistics properties (brownfield and value-add) for its own account and co-investment platforms. Revenue is realized through asset appreciation, lease income, and eventual sale of repositioned assets. Development is also conducted within a joint venture with Tristan Capital Partners (EPISO 6 fund) targeting value-add logistics properties across the Netherlands.
- Lease Income (Asset Management): GEM collects long-term rental income from tenants occupying its logistics assets. Properties are managed in-house (commercially, financially, and technically), providing full control over performance and tenant relationships. Assets are leased to logistics operators (e.g., SolaX Power Netherlands at Jupiterweg 1, Moerdijk; Rietveld Logistics Group at Visserijweg 4, Oosterhout).

GEM Real Estate competitors and assessment
Company assessmentDirect peers
- CTP: Pan-European logistics real estate developer and investor with a value-add brownfield/greenfield development model that directly parallels GEM's approach. CTP operates at vastly greater scale across 10+ countries but shares the build-and-hold philosophy and ESG-focused new-build pipeline.
- Hillwood: Privately-held US-based logistics real estate developer with growing European operations. Focuses on build-to-suit and speculative development with strong ESG positioning, paralleling GEM's GEMSTONE concept.
- OVG Real Estate: Dutch developer focused on sustainability-certified commercial and logistics buildings. Highly comparable on geography, ESG-first positioning, and Dutch institutional capital partnerships.
- Verdion: European logistics value-add developer focused on brownfield redevelopments and large-scale urban logistics. Deal-by-deal structure and last-mile/port-corridor strategy closely mirror GEM's Netherlands-focused playbook.
Broad incumbents
- Prologis: Global leader in logistics real estate with significant Netherlands footprint. Operates as a publicly-traded REIT offering scale, data, and capital advantages GEM cannot match, but serves the same tenant base.
- Panattoni: Europe's largest privately-owned logistics real estate developer with active speculative build strategy and Netherlands operations. Highly relevant benchmark on development pipeline, speculative lease-up risk, and ESG-certified new-build demand.
- VolkerWessels: Dutch-listed construction and real estate development conglomerate with logistics real estate exposure. Less specialized than GEM but relevant on Dutch market dynamics, construction cost trends, and ESG building demand.
- P3 Logistic Parks: Pan-European owner, developer, and manager of logistics properties with strong Netherlands presence. Direct functional overlap in customer segments and asset class but operates as a large institutional owner/investor platform.
- Logicor: Europe's largest owner-operator of logistics real estate with extensive Netherlands portfolio. Comparable on geography and tenant base but operates at vastly greater scale as an institutional long-hold owner.
- WDP (Warehouses De Pauw): Belgian-listed REIT focused on logistics and semi-industrial real estate across Benelux, France, and Romania. Strong Netherlands presence provides benchmarking on rents, yields, and tenant demand in adjacent geographies.
