What sustaynr gmbh does

SUSTAYNR GmbH is a Munich-based B2B SaaS company that operates the ESG Score platform, which delivers normalized sustainability scores (0-100) for standard indirect-procurement products such as office supplies, IT accessories, and construction materials. The scoring methodology combines category-specific criteria derived from analysis of over 5,000 chapters of Type I ecolabel certification guidelines with product-level sustainability data sourced from public records, certifier inputs, and manufacturer self-reports. Scores are independently reviewed by academic experts and institutes, recommended by BME (Germany's leading procurement industry body), and updated on a monthly (German site) or bi-weekly (English site) cadence to support best-in-class comparison within each product category.

The product surface comprises three interconnected components: the ESG Score web platform (sorting and filtering by sustainability), a browser extension deployed on Chrome, Edge, and Firefox that overlays scores directly on Amazon (9 marketplaces), OTTO Office, Bechtle, Conrad, and other online shops, and the ESG Datahub (esg-datahub.org), which provides a manufacturer data-entry portal and API distribution in BMEcat format. Revenue is generated through annual subscriptions at €250 (single-user) and €750 (multi-user, email-domain-based) tiers, with API access priced separately via the Datahub. The company serves corporate procurement teams (Siemens, WPS Management), public-sector buyers (TEK-SERVICE AG), digital marketplaces (wescale), retailers, and manufacturers seeking visibility for certified products.

The company is privately held and backed by HTGF (High-Tech Gründerfonds) and angels Rainer Hoffmann and Thomas Zachau (co-founders of H&Z Consulting). Founded by Jan Bussiek, formerly of B2B procurement platform Unite Mercateo, SUSTAYNR operates with a small core team (1-10 employees) and an advisory board of four industry and academic experts. Strategic emphasis is on independent, conflict-of-interest-free scoring, public-procurement compliance positioning, and ecosystem expansion via certifier and manufacturer data contributions.

Broad incumbents

• EcoVadis: Global leader in business sustainability ratings with scorecards across environment, labor, ethics, and procurement. Directly comparable as it provides ESG ratings used in procurement decisions, but operates at company rather than product level and serves a much broader enterprise market.
• Clarity AI: AI-powered sustainability analytics platform providing ESG ratings, climate data, and regulatory reporting tools for investors and corporates. Overlaps in ESG data/ratings and Scope 3 reporting use cases but primarily serves financial markets rather than procurement.
• DEKRA: Global testing, inspection and certification organization with ESG/sustainability advisory services. Comparable in Type I ecolabel certification expertise and serving corporate buyers with sustainability documentation, though broader scope and much larger scale.

Direct peers

• IntegrityNext: German-based SaaS platform for sustainable supply chain and procurement compliance, including supplier ESG monitoring and risk data. Closest direct peer in terms of geography, customer segment (procurement teams), and B2B SaaS delivery model.
• Sedex: Global platform for supply chain ESG data, including supplier assessments and product-level sustainability information. Comparable in providing ESG data feeds into procurement workflows and serving corporate buyers.

Emerging players

• Source Intelligence: Product compliance and ESG data platform providing supply chain transparency including product-level certifications and sustainability attributes. Comparable in focus on product-level data integrated into procurement catalogs.
• Manufacture 2030: Cloud platform helping manufacturers and buyers measure and reduce Scope 3 emissions across supply chains. Comparable in targeting procurement-led sustainability measurement, but focused on carbon rather than broader ESG product scoring.
• SupplyShift: Supply chain sustainability platform enabling buyers to assess supplier ESG performance and trace product-level sustainability data. Comparable in serving enterprise procurement teams with supplier/sustainability scoring.
• Sigli: Provider of product carbon footprint and ESG data feeds integrated into e-commerce and procurement platforms. Comparable product-level scope and API-based delivery model, but narrower focus on carbon footprint versus broader ESG criteria.

Regional players

• Unite Mercateo: Leading European B2B procurement marketplace where ESG Score founder Jan Bussiek previously led marketplace operations. Strategic adjacency — Unite could embed or compete with ESG Score in its platform, and serves a highly overlapping customer base in DACH indirect procurement.
