NEW YORK — Astronomer, the company behind Astro, a leading unified DataOps platform powered by Apache Airflow, has secured $93 million in Series D funding led by Bain Capital Ventures, alongside Salesforce Ventures and existing investors including Insight, Meritech, and Venrock, with Bosch Ventures seeking to participate. Astronomer will use the funding to expedite research and development, and to strategically expand the company’s international presence.
“While this is just one step in Astronomer’s journey to build a durable, lasting software company, we’re thrilled to have one of our earliest investors, Bain, leading the round,” said Andy Byron, CEO, Astronomer. “All of our investors are committed to Astronomer’s long-term vision because of our recent momentum, the massive market demand for the platform we’re building, and the macro tailwinds that support our vision. Whether it’s getting enterprise AI into production at scale, maximizing data platform value through cost optimization, or just driving more value from data in general–everything we do at Astronomer is at the heart of boardroom conversations across the world.”
The financing comes at a time of tremendous momentum for Astronomer and Airflow, the open-source framework and de facto standard for data orchestration that sits at the core of Astronomer’s offerings. In the past year, Astro expansion beyond data orchestration included data observability/lineage, data quality, integrated dbt workflows, cost optimization and other capabilities as Astronomer continues to invest in Astro as the leading unified DataOps platform.
Last fiscal year Astronomer saw:
- 150%+ YoY Astro ARR growth
- Improved operational efficiency, with a two year path to profitability
- World-class 130% Net Revenue Retention
- 90%+ product utilization with customers
Meanwhile, Airflow has surged in popularity alongside the rise of AI and MLOps. Airflow is used by more than 80K organizations and was downloaded more than 324M times in 2024. Astronomer’s engineering efforts are critical to driving Airflow releases, including the recent general availability of Airflow 3.0 – the most significant release in project history. This watershed release makes Airflow easier to use, with enhanced security and the ability to run anywhere, all while introducing an architecture that is tailor-made to support production AI at scale.
“We invested in Astronomer in 2019 with a simple bet: Airflow would become the standard for data orchestration,” said Enrique Salem, Partner at Bain Capital Ventures. “Today, it runs at over 80,000 companies and drives 30 million downloads a month. We backed Astronomer because they’re not only riding that wave; they’re building the enterprise control plane on top of it. As AI raises the stakes for reliable, scalable data infrastructure, we’re doubling down on our investment. Orchestration is just the start. The team at Astronomer are poised to unify the entire DataOps stack.”
