Union.ai Raises $38.1M to Scale AI Workflow Platform

Washington: Union.ai completes $38.1 million in Series A funding to expand infrastructure that helps engineering teams move AI projects from experimentation to production.

The round was led by existing investor NEA, with participation from Nava Ventures and new investor Mozilla Ventures. The total includes a previously announced $19.1 million portion.

Founded as the enterprise platform for Flyte, a widely adopted open-source AI orchestrator, Union.ai provides an end-to-end AI development infrastructure.

Flyte has crossed 80 million downloads, while its data validation framework Pandera has surpassed 100 million. More than 3,500 companies now run AI workloads on infrastructure powered by the platform.

The company addresses a fundamental challenge in AI development, which requires a different approach than traditional software. Legacy software infrastructure and development tools struggle to handle AI development requirements.

Union.ai’s platform covers orchestration as well as training, inference and observability. The system helps engineering teams manage complex machine learning and data workflows while maintaining reliability and reproducibility with automatic failure recovery, caching and versioning.

“This round came together as demand for AI orchestration is surging, and our open-source work is translating into clear commercial momentum,” Ketan Umare, CEO and co-founder of Union.ai, said. “Building AI requires a fundamentally different approach than traditional software, and engineering teams are now embracing that,” he added.

The funding will accelerate product development, expand engineering and field teams, and deepen investment in the company’s open-source community. The capital supports Union’s mission to build AI development infrastructure that enables faster scaling from experiment to production.
