Achetez un café à Jeroen Bouma

Thank you for stopping by! 👋

I'm a passionate open-source developer bringing Python and Finance together; making financial theory accessible, transparent, and practical for everyone from hobbyist investors to professional quants.

By buying me a coffee, you're directly supporting the time I spend building, expanding, and maintaining these projects; adding new financial models, improving documentation, and keeping everything up to date.

I'm actively maintaining the following open-source packages:

FinanceToolkit: 200+ financial metrics, ratios, and models including valuation, profitability, risk, technical indicators, Fama-French factor models, and macroeconomics. Every formula is fully transparent and documented. Now also available as an MCP server, letting Claude run financial analysis directly. Over 5K Stars.

FinanceDatabase: a database of 300,000+ financial instruments covering Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies, and Money Markets. Perfect for screening, filtering by sector or country, and building watchlists programmatically. Over 7K Stars.

Every coffee keeps these projects alive and growing, thank you! ☕
