What Sustera Group does

Sustera Group is a Nordic property lifecycle management company headquartered in Helsinki, Finland, with a regional headquarters in Stockholm, Sweden. Founded in 1989 (originally as Raksystems Insinööritoimisto Oy) and reorganized under the Sustera brand through 17 acquisitions completed between 2016 and 2023, the firm employs 459 people (79% in Finland, 21% in Sweden) and operates as a B2B professional services provider to property owners, real estate developers, construction companies, facility managers, and municipalities. Its service portfolio spans three divisions—Inspections & Surveys, Energy & Sustainability Services, and Projects & Supervision—alongside a Due Diligence practice offering Technical, Environmental, and ESG Due Diligence plus a Real Estate Warranty+ insurance product underwritten by Lloyd's.

The company's core technical differentiator is Geolo, a proprietary carbon-neutral construction heating and cooling solution developed with Rototec and Enersys that uses geothermal energy to provide emission-free temporary climate control during construction phases. Sustera is also a leading practitioner of international environmental certification schemes (BREEAM, LEED, WELL, RTYL) across both construction projects and existing buildings, holds in-house WELL Performance Testing capabilities as the first Finnish GBCI-authorized operator, and operates a GHG Protocol-aligned carbon footprint and carbon handprint methodology since 2020. The firm holds SBTi-validated climate targets and achieved WELL Platinum certification for its own Helsinki headquarters (Colony) in November 2025.

Sustera generates revenue through project-based professional services fees across four core streams: Inspections & Surveys, Energy & Sustainability Services, Projects & Supervision, and Due Diligence Services, supplemented by managed services revenue from Geolo. Distribution is direct-sales-led with localized country teams, service-specific expert contacts, and enterprise-level engagement with major Nordic property owners and developers; pricing is quote-based rather than tiered. The firm reported €61.1M in turnover for 2025 and is majority-owned by a fund managed by Capital Four (Copenhagen-based credit asset manager, €23bn+ AUM) following an October 2025 ownership transition from Trill Impact.
