Vellum, an enterprise development platform, has successfully raised $20 million in Series A funding. Leaders Fund led this significant investment round. The company provides infrastructure for building, evaluating, and deploying reliable AI products at scale.
Socii Capital also participated in the round, alongside existing investors Y Combinator, Rebel Fund, Pioneer Fund, and Eastlink Capital. This capital infusion will accelerate Vellum's product innovation. Furthermore, the company plans to expand into new verticals and global markets.
Advancing Enterprise AI Capabilities
Vellum's platform helps organizations operationalize AI, moving beyond prototyping to production. It addresses a critical enterprise gap where many companies lack a comprehensive AI strategy. Unlike broader machine learning platforms such as DataRobot or specialized MLOps tools like Weights & Biases, Vellum focuses on end-to-end workflow orchestration for mission-critical AI.
The Vellum platform is now generally available.
Top companies including Drata, Swisscom, Redfin, and Headspace currently utilize Vellum. They leverage the platform to automate customer support and scale secure, compliance-ready workflows. Vellum provides rigor, predictability, and repeatability to enterprise AI development.
