GOSSEYE

What GOSSEYE does

Gosseye n.v. is a third-generation, family-owned Belgian HVAC and sanitary installation specialist founded in 1946 and headquartered in Wortegem-Petegem, with a registered office in Ronse. The company employs approximately 20-30 staff and operates from two Belgian locations positioned on the language border, enabling bilingual service delivery across Flanders, Wallonia, and northern France. Its service portfolio covers four integrated disciplines: heating (condensing boilers, geothermal and aerothermal heat pumps, hybrid systems), ventilation (energy recovery systems for mid-sized to large-scale applications), air conditioning (split, VRV, and chilled water systems), and sanitary installations (water capture, distribution, drainage, and recovery). All four product lines are designed around energy savings, energy recovery, and energy optimization themes, with alternative energy systems and intelligent building management systems positioned as differentiators.

Gosseye serves industrial and commercial buildings exclusively, including offices, factory towers, apartments, castles, churches, sports complexes, and public infrastructure. Named customers span manufacturing (Samsonite in Oudenaarde), telecommunications (See Telecom), food production (Choc and Co), hospitality (Restaurant Nivelles), and public infrastructure (Waggelwater in Brugge, Steenkaai in Brugge). The company operates an enterprise field sales motion with direct client engagement on industrial projects, delivering full-service from concept through engineering, execution, and ongoing maintenance, including weekend support packages. Revenue is generated through professional services for installation work and recurring maintenance contracts.

The business model is project-based with custom quoting, supplemented by subscription-style maintenance packages. Go-to-market relies on direct field sales and a bilingual digital presence (gosseye.be in Dutch and French), with bottom-of-funnel conversion through website contact forms and quote requests. The company is privately held with no disclosed external investors, parent entity, funding rounds, acquisitions, partnerships, patents, or third-party certifications. No mobile app, API, or SDK is offered, and no AI/ML capability is evidenced in the source material.
