What WikiRate does

WikiRate is a nonprofit open ESG data platform operated by Wikirate International e.V., a German-registered association (eingetragener Verein) founded in 2013 and headquartered in Berlin. The platform aggregates over 9 million community-contributed data points across 152,870 companies, covering environmental, social and governance metrics drawn from 231,266 cited public sources. Users include civil society organizations (Fashion Revolution, BankTrack, Clean Clothes Campaign, World Benchmarking Alliance), academic institutions (University of Connecticut, Ewha Womans University, Columbia SIPA, AMD Berlin) and general consumers seeking transparent corporate sustainability information.

The platform is built on Decko, an open-source wiki framework using a card-based architecture in which Companies, Metrics, Answers, Projects, Datasets and Topics are each modeled as cards. Data access is provided through a self-serve web interface and a REST API with JSON and JSON-LD support, including authentication via API key and pre-built SDK wrappers in Python, Java and Ruby. Linked-data principles and an ontology guide enable cross-platform integration with systems such as Wikidata. All platform data is licensed under CC BY 4.0, with database infrastructure under CC BY-SA 4.0, and the core platform is provided free of charge to all users.

WikiRate is funded through grants and donations to Wikirate International e.V. rather than commercial pricing or equity capital. Growth is community-led and supported by partnerships with benchmark owners (GRI, Walk Free, CDP, OECD, Alliance for Corporate Transparency, Center for Political Accountability) who use the platform to publish metrics, datasets and comparative benchmarks. The organization employs 1-10 staff and is supported by a distributed contributor base of 10,412 contributors, 225 metric designers and 326 research groups.
