About


Arctos Alliance exists to ensure the long-term sustainability of Apache Arrow and Apache Parquet.

When corporate layoffs left many of the core open-source contributors without support, we came together to keep the projects independent, healthy, and community-driven.

Through Arctos, sponsors can directly fund the work of committers, maintainers, and fellows. Our Governing Board represents financial sponsors, our Steering Committee sets technical direction, and our Engineering Team ensures that Arrow and Parquet continue to thrive at the center of the modern data ecosystem.

By contributing, you are helping to:
  • Keep Arrow and Parquet neutral and independent.
  • Fund the ongoing development and maintenance of critical data infrastructure.
  • Support the engineers and researchers whose work powers analytics, machine learning, and high-performance computing worldwide.

Join us in building a sustainable future for Arrow, Parquet, and the open data ecosystem.
