The Story

The plumbing behind the data

Every dashboard, machine-learning model, and AI feature depends on data arriving in the right place, in the right shape, at the right time. The unglamorous machinery that makes that happen is called data orchestration, and Astronomer has built a business on doing it well. The New York company is the commercial steward of Apache Airflow, the open-source project that became the de facto standard for scheduling and managing data pipelines, and its flagship product, Astro, packages that engine into a fully managed, cloud-native platform.

Astronomer was founded in 2015 by Ry Walker, Greg Neiheisel, and Tim Brunk. It started in Cincinnati, Ohio before basing itself in New York City, and over the following decade it made a deliberate bet: rather than compete with Apache Airflow, it would become the place enterprises go to run it. That bet turned into deep involvement in the open-source project itself. Since 2018, Astronomer employees have helped steer every Airflow release, and the company employs a large share of the project's core committers.

The result is a company that sits at an unusual intersection - part open-source steward, part enterprise software vendor. Airflow is free to download and run. Astronomer's proposition is that running it reliably at scale, across clouds, with observability and support, is a job worth paying for.

“Astronomer is the best place to run Apache Airflow.”

Products & Services

What you can build with it

Astronomer's platform spans the full lifecycle of a data pipeline - from writing it as code, to running it across clouds, to watching it in production.

2022

Astro

The fully managed, cloud-native orchestration platform powered by Apache Airflow. Teams build, run, scale, and observe pipelines across AWS, Google Cloud, and Azure with autoscaling, CI/CD, role-based access, and deployment rollbacks.

2025

Astro Observe

A unified observability layer that gives a single pane of glass over pipeline health and the wider data supply chain - with AI log summaries, an Insights Engine, data lineage, and Snowflake cost management.

2019

Astronomer Software

A self-managed deployment for enterprises that need to run Airflow inside their own infrastructure, with the same tooling and support.

2023

Astro Cosmos

An open-source package that simplifies orchestrating dbt (data build tool) transformations directly inside Airflow.

2020

Registry & Astro CLI

A registry of Airflow providers, modules, and DAGs, plus a command-line tool for local development and one-command deploys.

2021

Astronomer Academy

Training and certification programs for Apache Airflow and the Astro platform, feeding the open-source community and enterprise teams alike.


The Problem It Solves

When a pipeline breaks at 3am

Data pipelines fail quietly and expensively. A broken job overnight can mean stale dashboards, a mispriced product, or a machine-learning model trained on missing data. Traditionally, keeping pipelines healthy meant a patchwork of cron jobs, custom scripts, and on-call engineers piecing together what went wrong from scattered logs.

Astronomer's pitch is to collapse that complexity. Orchestration decides when and how data moves; observability tells you the moment something breaks and why. Astro Observe merges both into one platform, because in production they were never really separate concerns. AI log summaries pinpoint the failing task and suggest next steps, and the Insights Engine flags risks before they become outages.

What sets Astronomer apart from managed rivals like Amazon MWAA and Google Cloud Composer, or alternative frameworks like Dagster and Prefect, is its position inside Airflow itself. Because it employs so many of the project's committers, the company can shape the roadmap of the very engine everyone else is repackaging. For enterprises already standardized on Airflow, that closeness is a practical advantage - migrations are faster and support runs deeper.

“Astro Observe provides all teams using Apache Airflow with an actionable view of their entire data supply chain.”

Customers & Business Model

Who uses it, and how it earns

Astronomer serves more than 700 enterprises across finance, healthcare, retail, manufacturing, and technology. Publicly referenced customers include Adobe, Marriott, Ford, Autodesk, Sweetgreen, and Foot Locker.

B2B SaaS core

Astro is sold on usage-based pricing that scales with deployment size, number of active deployments, and compute. Standard deployments range from hundreds to a few thousand dollars a month.

Enterprise contracts

Large customers sign custom annual agreements, with self-managed software licensing plus professional services, training, and support layered on top.

Open source as funnel

The free Apache Airflow project is the top of the funnel - millions of engineers adopt it, and a share graduate to Astronomer's managed platform.

Proof point: Autodesk

Autodesk migrated 536 Oozie pipelines across 25 data-engineering teams onto Astro in roughly 12 weeks - a case study in how migration speed becomes a competitive moat for a managed orchestration vendor.
