FinBridge

Provides a unified API and database for Korean and U.S. filings, financials, prices, and technicals to screen and compare listings across both markets

The product is an infrastructure API and data platform that normalizes Korean and U.S. filings, financials, prices, and technicals into a single schema and SQLite database, solving fragmented access to DART and EDGAR data and the inability to screen and compare listings across both markets together. It sells to developers, data teams, and finance professionals in B2B contexts who build agents, screeners, and research workflows. It is positioned as a single connection replacing two vendors, ingesting only redistributable public data from primary authorities and normalizing it nightly into the same fields and units.
