Pete DeJoy

Pete DeJoy is the co-founder and interim CEO of Astronomer, the New York-based data orchestration company built on Apache Airflow. A Bowdoin-trained chemist who spent eight years scaling Astronomer's product from an early commercial offering to a platform trusted by enterprises, he stepped into the CEO seat in July 2025 after a viral concert-video scandal took out his predecessor.
