Astronomer provides a fully-managed platform for building, running, and monitoring data pipelines using Apache Airflow, with native support for AI and MLOps workloads.
Astronomer, founded in May 2015 by Ry Walker, Greg Neiheisel, and Tim Brunk, originally launched as USERcycle, an engagement analytics tool, before pivoting to data orchestration in 2015. The company built its managed platform around Apache Airflow, Airbnb's open-source workflow engine, officially committing to the Airflow-centric strategy in May 2018. Today, Astronomer operates as the commercial leader in managed Apache Airflow, serving over 700 enterprise customers including Uber, Stripe, LinkedIn, OpenAI, GitHub, and Ford Motor Company.
The platform, called Astro, handles orchestration across multiple cloud providers and on-premises environments, with customers executing over one billion tasks in 2024—a 1,774% increase from 2023. Astronomer has raised $376 million across four funding rounds, most recently closing $93 million in Series D funding in May 2025 at a $775 million valuation. The company reports 150% year-over-year Astro annual recurring revenue growth, a 130% net revenue retention rate, and projects a two-year path to profitability.
In April 2026, Astronomer launched Otto, a data engineering agent built specifically for Airflow that assists with DAG authoring, failure investigation, and upgrade planning. The market for data orchestration is expanding rapidly, driven by AI and MLOps adoption—Astronomer's 2025 State of Airflow Report found that 55% of Astro customers use Airflow for machine learning and AI workloads, and over 85% expect growth in external-facing, revenue-generating applications. In July 2025, the company experienced a significant leadership transition when CEO Andy Byron resigned following a public incident at a Coldplay concert; co-founder Pete DeJoy, who was serving as Chief Product Officer, assumed the interim CEO role.
