What Optigrun does

Optigrün international AG is a family-owned, Germany-based provider of green roof and building greening systems, founded in 1972 and headquartered in Krauchenwies-Göggingen in the Sigmaringen district of southern Germany. The company employs approximately 160 staff at headquarters and operates wholly-owned subsidiaries in Austria (Vienna), the Benelux region (Nijkerk, Netherlands), and the UK (Milton Keynes), with active market presence across more than 20 countries. Approximately 140 trained partner companies execute installation and maintenance across Europe, and the company reports greening roughly 5 million square meters of roof surface annually across ~9,000 construction projects, with 2022 sales exceeding €100 million for the first time.

The company's core offering is a portfolio of nine integrated roof system solutions — including Retention, Economy, Lightweight, Natural/Biodiversity, Pitched, Solar, Garden, Landscape, and Public/Communication roofs — supported by more than 100 individual components such as drainage boards (FKD series), retention boxes (WRB series), high-retention meander plates (FKM series), substrates, vegetation, inspection chambers, and proprietary solar mounting frames. Key proprietary technologies include Smart Flow Control (a weather-data-driven dynamic throttle awarded the GaLaBau Innovation Award in 2016), Retention Roof System 2.0 with WRB hollow-body retention boxes, Mander Plate achieving peak runoff coefficients of 0.01 per FLL standards, three generations of solar mounting systems (Sunroot 2010, 2015, Optigrün-Solar 2020), the SOLon vertical PV system launched in 2023 with SOLYCO Solar AG, and ballast-supported Optisafe fall protection and SkyGard railing systems that preserve waterproofing integrity.

Revenue is generated through three primary streams: B2B green roof system solutions sold to architects, planners, and specialized construction companies via the partner network and direct technical sales support; pre-project technical consulting services including wind suction calculations, drift resistance, flood proof, and water balance determinations; and direct-to-consumer e-commerce via dachbegruenung24.de for private homeowners. Pricing is project-based custom quotation with no publicly disclosed rates. The GTM motion is hybrid: sales-led technical consulting supported by a channel of 140 trained partner companies, supplemented by online self-serve for residential customers. Customer concentration is distributed across thousands of projects and multiple verticals (real estate, healthcare, education, technology), and the company maintains partnerships with FRÄNKISCHE Rohrwerke (water engineering) and SOLYCO Solar AG (PV modules), alongside memberships in industry associations including BuGG, DGNB, VFB, and SFG.

Products and services

• Retention Roof System (Dach retencyjny) Intelligent rainwater management system that stores and gradually releases rainwater, achieving peak runoff coefficients as low as 0.01 in accordance with FLL guidelines and incorporating Smart Flow Control technology for dynamic, weather-data-driven water management. Sold as a complete system solution to architects, planners, and specialized construction firms.
• Economy Roof System (Dach ekonomiczny) Cost-effective green roof system designed for large surface areas with minimal structural reserves, suitable for extensive greening applications. Sold as a complete Optigrün system solution.

Scale indicators7 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Sika AG: Sika is a Swiss-headquartered global specialty chemicals and construction materials company with roofing, waterproofing and increasingly green roof offerings. As a broad incumbent, it competes on waterproofing-adjacent components and large project specifications where Optigrün also bids, though green roofs are not its core focus.
• BMI Group: BMI Group (Braas Monier Icopal) is a large European pitched and flat roofing manufacturer offering green roof and BIPV-adjacent solutions across multiple markets. As a broad incumbent with portfolio roofing products, it competes with Optigrün where developers bundle full roof assemblies with greening.
• Soprema Group: Soprema is a French-headquartered global waterproofing and roofing manufacturer that has expanded into green roof systems (Sopranature). It is a broad incumbent comparable in waterproofing substrate layer to Optigrün's full-system offering and competes for the same building envelope specifications.

Direct peers

• LiveRoof, LLC: LiveRoof is a North American green roof system manufacturer offering modular pre-vegetated roof systems. While its product format is more module-based than Optigrün's full-system approach, it competes directly for the same building owner, architect, and installer customers in the green roof specification chain.
• Sempergreen Group: Sempergreen is a Netherlands-based manufacturer and installer of green walls and green roof systems, particularly strong in sedum mats and ready-made vegetation. It directly competes with Optigrün's Nature Roof and Garden Roof offerings across Benelux and Western Europe.
• ZinCo GmbH: ZinCo is a German-headquartered manufacturer of green roof and rainwater management systems with comparable system portfolios (retention, extensive, intensive). It is the most direct head-to-head competitor to Optigrün in the DACH market with similar channel partner approaches.
• Vegetal i.D. Vegetal i.D. is a French green roof and green wall specialist offering project design and installation across Europe. It is comparable to Optigrün's garden roof and landscape roof product lines and overlaps in southern/Western European markets.
• Xero Flor North America: Xero Flor is a US-based green roof system manufacturer supplying pre-vegetated mats and integrated drainage/substrate systems to projects in North America. Comparable to Optigrün's system-solutions approach (Mander Plate retention, substrates, retention boxes), differing mainly by geography.
• Bauder GmbH & Co. KG: Bauder is a leading European roofing systems manufacturer offering green roof and waterproofing solutions across Germany, UK and wider Europe. Its BauderGREEN system competes on the same specifications (retention, biodiversity, solar) that Optigrün sells into commercial and public projects.

Others

• Arup Group: Arup is a global engineering and design consultancy that advises developers and architects on green roof specifications and stormwater retention strategy. It is not a system manufacturer but shapes specifications that often lock in Optigrün or competing suppliers, making it a relevant ecosystem participant rather than direct competitor.
