History of Development

In 2008, pandas development began at AQR Capital Management. By the end of 2009 it had been open sourced, and is actively supported today by Lambda Foundry, a company focused on building high-performance and high-productivity tools for Finance. Please see the commercial support page for full details.

There is also a community of like-minded individuals around the world who contribute their valuable time and energy to help make open source pandas possible. Thank you to all of our contributors.
