Vellum, a leading enterprise-grade platform for building, testing, and deploying mission-critical AI solutions, announced it has raised $20 million in Series A funding. The round was led by Leaders Fund, with additional participation from Socii Capital as well as returning investors Y Combinator, Rebel Fund, Pioneer Fund, and Eastlink Capital.
This investment highlights the surging demand for scalable, production-ready AI in the enterprise sector and underscores Vellum’s strong customer momentum. With this new funding, Vellum plans to fast-track its product roadmap and expand into new industries and international markets. The partnership with Leaders Fund—known for its deep expertise in enterprise go-to-market strategies—will help Vellum bring its AI development platform to more businesses around the world.
“Generative AI has captured the imagination of nearly every industry, but turning that potential into reliable, production-ready systems remains a massive challenge,” said Akash Sharma, co-founder and CEO at Vellum. “For many teams, it still feels like guesswork. Vellum changes that. We provide the infrastructure that brings rigor, predictability and repeatability to AI development, so teams can build with confidence and scale with clarity.”
Enabling Scalable, Reliable Generative AI Development
This funding milestone further cements Vellum’s role as an emerging leader in enterprise AI development. Despite the rapid growth of AI adoption, 54% of companies still lack a clear AI strategy and 56% face challenges with immature data systems, making the journey from prototype to production daunting. Vellum is uniquely positioned to help organizations overcome these barriers and transform experimental AI projects into measurable business outcomes. With the Series A funding, the Vellum platform is now generally available (GA) for teams looking to move beyond prototyping.
Vellum’s unified platform allows cross-functional teams to manage end-to-end AI workflows-connecting models, tools, and business data through a centralized interface. By integrating workflow orchestration, evaluation and testing, deployment, and monitoring, Vellum empowers enterprises to build sophisticated AI systems that deliver consistent, trustworthy results. This comprehensive approach has made Vellum an essential infrastructure layer for industries where security, compliance, and reliability are paramount.
“The rise of LLMs and AI has changed how software is built, but the need for reliability and structure remains the same,” said Gideon Hayden, co-founder and Managing Partner at Leaders Fund. “Most large organizations developing AI applications are stuck in the prototype phase, struggling to make AI systems reliable, repeatable and ready for production. Vellum’s test-driven development platform meets the moment. The team has quickly earned the trust of leading enterprise customers by solving the core challenges that slow AI development: maintaining reliability, accelerating iteration and enabling collaboration. Vellum is setting a new standard for how AI gets built, and we’re proud to support that vision.”
