Vellum
FeaturedBuild, test, and deploy production AI workflows.
Founded in 2023, Vellum was built to solve one of the biggest challenges in enterprise AI development — moving from a promising LLM prototype to a reliable, production-ready AI product. Vellum provides a unified platform for prompt engineering, model evaluation, regression testing, and deployment monitoring, giving AI product teams the infrastructure to iterate quickly and ship with confidence. On May 7, 2026 — just two days ago — Vellum raised $25 million in a Series A round led by Leaders Fund. The platform is used by hundreds of AI engineering teams at companies building LLM products across industries including legal, healthcare, finance, and customer support.
