The Open-Source Debt Nobody in Finance Wants to Talk About

The financial industry relies heavily on open-source software, yet it has largely failed to provide adequate funding or support to maintain these critical tools. Most software powering global financial markets was developed by volunteers and maintained by small teams, with no revenue generated from these efforts. EXANTE, a prime broker holding $4 billion in client assets and serving 20,000+ professional investors, has taken steps to address this issue by launching the Gecko Fund in June 2026.

This grant program aims to fund existing open-source projects that run in production at major institutions, recognizing that these projects are often maintained by people who have never received compensation for their work. The Gecko Fund's first grant went to Kryo, a Java serialization framework in use for over a decade, highlighting the importance of such infrastructure.

Nathan Sweet, creator of Kryo, expressed gratitude for the support, acknowledging the reciprocal dependence between the open-source community and the financial industry. EXANTE's Chief Technology Officer, Richard Forss, emphasized that open-source infrastructure is essential for modern businesses and financial markets. The Gecko Fund aims to ensure the resilience, security, and sustainability of this critical infrastructure by providing funding for projects in various programming languages and tools relevant to the financial ecosystem.
