Intrinio is a financial data platform that provides developers, analysts, and fintech companies with affordable access to market data, company fundamentals, ESG data, and alternative datasets through clean REST APIs. Founded in 2012, Intrinio has positioned itself as the accessible, developer-friendly alternative to expensive legacy data providers like Bloomberg and FactSet. The platform covers US equities, international stocks, ETFs, mutual funds, options, cryptocurrencies, forex, and economic indicators. Company fundamentals include standardized financial statements, calculated ratios, earnings estimates, and ownership data going back decades. Real-time and delayed quotes are available from major US exchanges. Intrinio's Excel Add-In enables analysts to pull live data into spreadsheets without coding. SDKs for Python, JavaScript, Ruby, Java, and other languages accelerate integration. The Data API provides flexible querying of financial data points. ESG and sustainability data has become increasingly prominent. Alternative datasets include web traffic, app downloads, and other non-traditional financial signals. Intrinio's pricing is significantly more accessible than traditional financial data providers, making it viable for startups and individual developers. The company provides excellent documentation and a responsive support team. Intrinio is popular with fintech startups building investment apps, financial analysts building custom models, and developers creating financial tools. Its free tier enables experimentation before commitment.
