Finance is one of the slowest industries to embrace open- source, married to legacy software that is too risky to change. It recreates technology stacks, introducing unnecessary risks, stagnation, and inefficiency. Thousands of firms do proprietary integrations to the same connectivity and data transformations.

We are pioneering a new era of open infrastructure for quantitative finance. Our community-focused, fully-open source model gives anyone cutting-edge quantitative research tools. We believe in building in public and sharing our work openly. We embrace new, innovative business models to make our work sustainable and accessible. Today, LEAN manages billions in assets for thousands of clients and is becoming the new standard to launch your new fund.
