What Union.ai does
Union.ai is an AI development infrastructure company headquartered in Bellevue, Washington, founded in 2021 as the commercial steward of the open-source Flyte project, which originated at Lyft in 2016 and was open-sourced in 2020. The company provides a Kubernetes-native workflow orchestration platform that enables engineering teams to build, deploy, and scale AI/ML and data pipelines in production, serving enterprises across biotech and life sciences, geospatial, autonomous systems, and financial services.
The company's core technology centers on Flyte 2, an open-source AI orchestrator written in Python with over 80 million downloads and 10,000+ community members. Flyte 2 introduces infrastructure-as-context, a self-healing architecture where pipelines recover from logic and infrastructure failures autonomously, and supports fully dynamic runtime decision-making for agentic AI workloads. The commercial platform, Union 2.0, is built on Flyte 2 and provides end-to-end orchestration, training, inference, and observability with a Zero Trust split-plane architecture where customer data never leaves the customer's own cloud environment. Supporting tools include the Flyte Python SDK, uctl CLI, Pandera (data validation framework with 100M+ downloads), Agent Chat UI, MCP server capability, and a free Devbox local sandbox.
Union.ai operates a primarily enterprise subscription revenue model with Union Cloud deployed in customer AWS or GCP accounts, distributed via direct enterprise sales, AWS Marketplace, and GCP Marketplace, with product-led developer adoption through the free Devbox sandbox. The company has raised $38.1M cumulatively across seed and Series A rounds led by NEA, with participation from Nava Ventures and Mozilla Ventures, and reports 3X revenue growth with 2.6X customer base expansion in 2025. Named enterprise customers include Johnson & Johnson, Lockheed, Spotify, Woven by Toyota, Wayve, Warner Bros. Discovery, Gojek, and over 30 Fortune 100 companies, with more than 3,500 companies total using the platform.

Union.ai competitors and assessment
Company assessmentDirect peers
- Prefect: Prefect is a workflow orchestration platform purpose-built for data engineers and ML practitioners, with Python-native authoring and a managed cloud offering. It directly competes with Union.ai/Flyte in the same enterprise AI/ML orchestration category.
- Dagster: Dagster provides an asset-centric, Python-native orchestration platform for data and ML pipelines, with strong emphasis on data lineage and observability. It competes head-to-head with Union.ai for enterprise AI/ML workflow orchestration workloads.
- Temporal: Temporal offers durable execution and orchestration for long-running, fault-tolerant workflows, with strong adoption in AI agent and data engineering use cases. Its self-healing durable execution model directly overlaps Flyte 2's positioning.
- Modal: Modal provides a serverless compute platform for AI/ML workloads with Python-native authoring and on-demand scaling. It targets the same AI engineering teams Union.ai serves, with overlapping value props around developer velocity and runtime orchestration.
- Anyscale: Anyscale is the commercial platform behind the open-source Ray distributed compute framework, providing orchestration and scaling for AI workloads. Flyte integrates with Ray, but Anyscale competes for the orchestration and runtime layer of enterprise AI pipelines.
- Argo Workflows: Argo Workflows is a Kubernetes-native, open-source workflow engine for orchestrating parallel jobs, often deployed on EKS for ML pipelines. It is the closest open-source competitor to Flyte's Kubernetes-native orchestration model.
- Metaflow (Netflix / Outerbounds): Metaflow is a Python framework originally built at Netflix for ML/AI workflow orchestration, now commercialized by Outerbounds. It directly competes with Flyte for ML engineering teams building production AI pipelines.
Broad incumbents
- AWS Step Functions / SageMaker Pipelines: AWS bundles Step Functions and SageMaker Pipelines as managed orchestration services for ML workflows within the AWS ecosystem. As a broad incumbent, AWS offers overlapping orchestration but as part of a much wider cloud platform that does not specialize in agentic or self-healing AI workflows.
- Google Cloud Composer (Airflow): Google Cloud Composer is a managed Apache Airflow service for workflow orchestration on GCP, often paired with Vertex AI Pipelines for ML. As a broad incumbent, it competes with Union.ai for orchestration workloads within GCP environments.
- Databricks Workflows / Lakeflow: Databricks offers workflow orchestration (Jobs, Lakeflow) tightly integrated with its lakehouse data platform and MLflow. As a broad incumbent, it competes for enterprise ML orchestration but is positioned as a data platform rather than a dedicated AI runtime.
