RFU research

What RFU research does

RFU research GmbH is a Vienna-based, privately held sustainability research and ESG ratings provider founded in 1997 by Mag. Reinhard Friesenbichler. The firm operates with a small staff of cross-disciplinary sustainability specialists (about 9-10) and serves institutional clients including asset owners (pension funds, insurers, church institutions), asset managers, banks, corporates, sovereigns and sub-sovereigns, and stock exchanges or index providers across DACH, Central and Eastern Europe, and selected international markets such as Vietnam.

The company's core technology is a suite of proprietary sustainability rating models: the Corporate Rating (six stakeholder groups across four management levels with approximately 100 criteria operationalized by ~400 indicators), the Sovereign Rating (three-pillar society/environment/economy model using Max-Neef human needs theory, Bossel system theory, and Stockholm Resilience Centre planetary boundaries, covering ~200 countries), the Sub-Sovereign Rating for states and cities (launched 2021/2022), and the Commodity Rating for ~70 products across the full life-cycle (launched 2018/2019). An absolute A+ to C- rating scale with bell-curve distribution underpins the analytics. The firm is ISO 9001:2015 certified (Quality Austria) and is currently filing with ESMA for authorization as a micro ESG Rating Provider under EU directive 2025/3005. It also co-develops and maintains flagship indices VÖNIX (with the Vienna Stock Exchange) and CECE SRI, and publishes the annual Austrian ESG Funds Survey and monthly Going Green expert column.

RFU research operates a B2B enterprise field-sales go-to-market targeting institutional clients, delivering customized sustainability research subscriptions with quarterly-updated investment universes, bespoke consulting, and Second Party Opinions (SPO) for Green Bonds, Social Bonds, promissory note loans, and loans. The business is bootstrapped with three concentrated shareholders (founder Reinhard Friesenbichler, Ariane Friesenbichler, and Catherine Cziharz), no external institutional investment, and no disclosed revenue. Cumulative investment products built on rfu know-how since 1997 reach a total volume of "several billion euros," and the VÖNIX index delivered +50% in 2025/2026.

Expansion highlights6 records

Broad incumbents

• Morningstar Sustainalytics: One of the largest global ESG ratings and research providers, owned by Morningstar. Overlaps with rfu's corporate ESG ratings and SPO services, but at vastly greater scale and global coverage across corporate, sovereign, and country-risk dimensions.
• MSCI ESG Research: Global ESG and climate rating provider serving institutional investors with corporate and sovereign ESG data. Like rfu, MSCI produces ratings that feed sustainable investment universes, but with dramatically larger coverage and analytical scale.
• ISS ESG: Institutional Shareholder Services' ESG business provides corporate, sovereign, and country ESG ratings plus Second Party Opinions for green/social bonds — a near-perfect overlap with rfu's full product suite. ISS also acquired oekom research, a historical German-speaking direct peer.
• Moody's ESG Solutions: Built on Vigeo Eiris, Moody's offers ESG scores, SPOs for sustainable finance instruments, and credit-relevant ESG data. Comparable to rfu's corporate, sovereign, and SPO offerings, with significantly deeper global distribution.
• S&P Global ESG: S&P Global's ESG and S&P Dow Jones Indices divisions provide corporate, sovereign, and commodity-related ESG data and indices (e.g., S&P ESG Index family). Comparable to rfu's index heritage (VÖNIX, CECE SRI) and corporate/sovereign research offering.
• FTSE Russell ESG: Part of the London Stock Exchange Group, FTSE Russell builds sustainable investment indices (e.g., FTSE4Good, ESG indices) and provides ESG data. Comparable to rfu's VÖNIX/CECE SRI index business and corporate research offering, but at global scale.

Direct peers

• Imug | Rating: German ethical and sustainability rating agency specialized in issuer and fund ratings for institutional investors. Like rfu, it is a comparable-sized German-speaking specialist focused on ethical/sustainable investment research rather than a global mega-rater.

Regional players

• Inrate: Swiss sustainability rating agency providing ESG ratings on companies, countries, and funds for institutional investors. Comparable to rfu in scope and methodology style, but primarily serves the Swiss market rather than DACH at large.

Emerging players

• RepRisk: Data-driven ESG risk analytics provider focused on publicly available information and controversies. Comparable to rfu's institutional research customer base but differentiated as a data-vendor rather than a full sustainability rating.
• EcoVadis: Global sustainability ratings platform focused on corporate supply chains and procurement use cases. Compares to rfu's Corporate Rating model, but focused on buyer-side (procurement) rather than purely investor-side sustainability research.
