Funding Round attributes
On May 1, 2025, Astronomer, the company behind the unified DataOps platform Astro powered by Apache Airflow®, announced the successful completion of a $93 million Series D funding round. The financing was led by Bain Capital Ventures, with participation from Salesforce Ventures and existing investors including Insight Partners, Meritech Capital, and Venrock. Bosch Ventures is also seeking to participate in this round.
The newly secured capital is earmarked to accelerate Astronomer's research and development initiatives and to support the strategic expansion of its international operations. This infusion of funds comes at a time when the company is experiencing significant momentum, particularly with the widespread adoption of Apache Airflow, the open-source framework central to Astronomer's offerings.
In the previous fiscal year, Astronomer reported over 150% year-over-year growth in Annual Recurring Revenue (ARR) for its Astro platform. The company also achieved a Net Revenue Retention rate of 130% and reported that over 90% of its customers are actively utilizing its products. These metrics indicate strong customer engagement and satisfaction with Astronomer's solutions.
Apache Airflow's popularity has surged in tandem with the rise of artificial intelligence (AI) and machine learning operations (MLOps). In 2024, Airflow was downloaded more than 324 million times and is now used by over 80,000 organizations. Astronomer's engineering team has played a pivotal role in driving the development of Airflow, including the recent release of Airflow 3.0, which introduced enhanced security features and improved usability.
