Polars, the Amsterdam-based company behind the high-performance open-source DataFrame library, has announced the successful completion of an €18 million Series A funding round. The round was led by Accel, with participation from Bain Capital Ventures (BCV), which had previously invested during the company’s seed stage.
This new capital will be instrumental in advancing Polars’ mission to simplify and enhance data processing workflows for developers and data scientists worldwide. Since its inception, Polars has experienced significant growth, expanding its user base from 250,000 to over 23 million monthly users. The company’s capabilities have evolved to include faster data processing, streaming execution, and improved cloud interoperability.
A key milestone in Polars’ development is the launch of Polars Cloud, a managed data platform that integrates low-latency, distributed data processing within the Polars ecosystem. This platform enables users to scale their data operations seamlessly without the need to rewrite code for different environments.
