Prefect

Prefect develops workflow orchestration software for data, ML and AI agent workloads. Users write workflows as plain Python functions with decorators, and the open-source Apache 2.0 framework shares its engine with Prefect Cloud, which adds a managed control plane, scheduling, retries and monitoring. The website also presents FastMCP, an open-source framework for building MCP servers, and Dagster as products built by one team.

The website names data, ML and agent engineering teams, from startups to enterprises, as its users, and lists customer stories including Ramp, WHOOP, Cash App and Snorkel AI. Revenue comes from Prefect Cloud subscriptions: a free Hobby plan, a Starter plan listed at $100/mo, a Team plan listed at $100/user/mo, and custom-priced Enterprise plans. Plans include included hours of Prefect Serverless managed compute.

The company describes itself as remote-first with a distributed team. The careers page lists eight open roles, including Staff Platform Engineer, Director of Product, Developer Success Engineer and Senior Sales Engineer, with one role marked UK-based within EMEA. The website does not state a founding year or headquarters city.
