Prefect

Prefect (operating via prefect.io) is a pioneering open-source workflow orchestration and durable execution platform engineered to build, monitor, and scale resilient data pipelines, machine learning models, and agentic workflows. Founded in 2018 and trusted by over 25,000 engineers globally, the enterprise fundamentally transforms how data teams automate complex operations and eliminate pipeline friction. Moving far beyond traditional rigid DAG definitions and legacy orchestration systems, Prefect natively unifies Pythonic execution with a managed cloud control plane, allowing developers to turn standard Python functions into production-grade, fault-tolerant pipelines using simple decorators without learning complex domain-specific languages (DSLs). The company powers mission-critical workloads for thousands of organizations, from digitally native startups to Fortune 500 enterprises like Progressive Insurance, Flatiron Health, and Ramp. Under the hood, their technology core leverages a highly secure hybrid execution model—ensuring sensitive enterprise data never leaves the user’s infrastructure (VPC)—while delivering centralized observability, automatic state tracking, robust retry logic, and seamless integrations with modern AI and data tools. Capturing massive market acceleration and successfully orchestrating over 100,000 mission-critical workflows every minute, Prefect remains a definitive cornerstone of modern data engineering, empowering teams to clear technical debt, build intelligent context layers, and turn massive data operations into a reliable, automated advantage.
