Thank you for visiting my GitHub Sponsors page! 👋

I'm Jeroen Bouma, a Quantitative Investment Strategist at a.s.r. asset management, where I work on the quantitative and AI models behind Solvency II internal model calculations, lifecycle investing and portfolio optimization. Before that I worked at OpenBB and PGGM. In my own time I build open-source tools that make financial analysis transparent and accessible to everyone.

Open-Source Projects

  • Finance Toolkit: 500+ financial methods, from ratios and valuation models to risk, performance and econometrics, each written out so you can see exactly how a number is calculated. Also available to AI assistants such as Claude and ChatGPT through its MCP server. 5,300+ GitHub stars and 640,000+ downloads.
  • Finance Database: 300,000+ symbols across Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies and Money Markets. 9,300+ GitHub stars and 600,000+ downloads.

Both are used by thousands of developers, researchers and investors, and I maintain and expand them in my own time.

Why Sponsor?

Your sponsorship gives me more time to add new financial methods, keep the data and documentation up to date, and respond to issues and ideas from the community. Every contribution directly supports free, transparent tools for financial analysis.

Thank you for considering sponsorship!

Reaching this goal would further validate my work and motivate me to put more hours into it.
