The company reports growth from 250k to over 23M monthly users since its seed round and plans to use the new funds to make Polars OSS fully streaming, build a state-of-the-art distributed engine for cloud and on-premises use, and expand Polars Cloud into a full managed data platform with autoscaling, query insights, and profiling. Polars Cloud is currently live on AWS with on-premise sign-up available. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Polars Cloud and how does it relate to the open source Polars library? Polars Cloud is a managed data platform built on top of open source Polars that adds distributed, low-latency data processing, managed hardware, autoscaling, and query profiling. It lets a Polars query written for a single machine run in the cloud by adding a remote() call within a ComputeContext, without rewriting the DataFrame API. It is currently live on AWS, with on-premise deployment available by signup. _Developers deciding how to scale DataFrame workloads can track Polars Cloud updates on daily.dev._ ### How much funding did Polars raise in its Series A round? Polars raised €18 million in a Series A round led by Accel, with participation from BCV, which had also backed the earlier seed round. The company states its monthly users grew from 250,000 to over 23 million since the seed investment, and the new funds will go toward making Polars OSS fully streaming and building a distributed query engine. _Anyone evaluating data-processing tools can follow Polars funding and roadmap news on daily.dev._ ## Similar posts on daily.dev - [Decathlon Switches to Polars to Optimize Data Pipelines and Infrastructure Costs](https://daily.dev/posts/decathlon-switches-to-polars-to-optimize-data-pipelines-and-infrastructure-costs-5gcd7b1tn) · InfoQ · 70 upvotes · 0 comments - [Dash0 Acquires Polar Signals for Continuous Profiling and GPU Visibility](https://daily.dev/posts/dash0-acquires-polar-signals-for-continuous-profiling-and-gpu-visibility-hlvy4k5hl) · DevOps.com · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#venture-capital](https://daily.dev/tags/venture-capital), [#data-engineering](https://daily.dev/tags/data-engineering), [#distributed-systems](https://daily.dev/tags/distributed-systems), [#polars](https://daily.dev/tags/polars) [View this post on daily.dev](https://daily.dev/posts/polars-raises-18m-series-a-to-build-fast-ergonomic-data-processing-at-any-scale-jioa4mtb0) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Polars raises €18M Series A to build fast, ergonomic data processing at any scale","url":"https://daily.dev/posts/polars-raises-18m-series-a-to-build-fast-ergonomic-data-processing-at-any-scale-jioa4mtb0","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/polars-raises-18m-series-a-to-build-fast-ergonomic-data-processing-at-any-scale-jioa4mtb0"},"datePublished":"2026-08-16T08:53:25.151Z","dateModified":"2026-08-16T08:55:37.263Z","description":"Polars, the DataFrame library, raised €18M in Series A funding led by Accel with participation from BCV.
