HedgeID provides a continuously updated dataset mapping the global institutional capital markets ecosystem, covering approximately 700,000 verified contacts and 200,000 firms across hedge funds, asset managers, allocators, brokers, trading venues, and service providers. Each entity is enriched with structured metadata, including firm type, strategies, asset classes, technologies used, regulatory profiles, and hierarchical relationships. The dataset is built through a hybrid approach combining programmatic ingestion of public regulatory filings, AI-driven entity classification, and tagging.
