Vellum: $20 Million Series A Raised For Enterprise Development Platform

By Amit Chowdhry • Jul 15, 2025

Vellum, a leading enterprise platform for building, testing, and deploying mission-critical AI products, has announced a $20 million Series A funding round. The round was led by Leaders Fund, with participation from Socii Capital and returning investors Y Combinator, Rebel Fund, Pioneer Fund, and Eastlink Capital.

This funding reflects strong customer demand and will accelerate product development, enabling Vellum to expand into new verticals and global markets. The partnership with Leaders Fund will be crucial in bringing Vellum’s AI development platform to more organizations worldwide.

Vellum’s platform, now generally available, positions itself as the emerging standard for enterprise AI development. It helps large organizations transition experimental AI efforts into scalable, measurable business outcomes, addressing challenges that many companies face due to a lack of comprehensive AI strategies and mature data systems.

The platform provides cross-functional teams with a centralized control panel to orchestrate end-to-end AI workflows by connecting models, tools, and business data. This integrated approach, which combines workflow orchestration, evaluation, testing, deployment, and monitoring, enables organizations to build reliable, complex AI systems. Vellum has become essential infrastructure for companies in highly regulated industries requiring strict security, compliance, and reliability.

Vellum helps teams overcome key challenges in moving AI from prototyping to production by offering:
1.) AI workflow definition: A visual UI builder and SDK for collaborative mapping, testing, and refining of AI logic.
2.) End-to-end evaluation: A robust testing suite to catch failures before production.
3.) Safe deployments: Enables updates and new versions without risky redeployments, offering precise version control.
4.) Live monitoring and continuous improvement: Real-time observability for system behavior and feedback loops for testing.

Leading companies like Drata, Swisscom, Redfin, and Headspace already use Vellum to power their AI initiatives, from automating customer support to data extraction and content generation. Drata, a security and compliance automation provider, leverages Vellum for secure, scalable AI workflows across over 7,000 customer environments, ensuring accuracy and compliance.

Vellum plans to use the Series A funding to continue developing its platform and expand its global market presence, leveraging Leaders Fund’s go-to-market expertise.

KEY QUOTES:

“Generative AI has captured the imagination of nearly every industry, but turning that potential into reliable, production-ready systems remains a massive challenge. 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.”

Akash Sharma, co-founder and CEO at Vellum

“The rise of LLMs and AI has changed how software is built, but the need for reliability and structure remains the same. 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.”

Gideon Hayden, co-founder and Managing Partner at Leaders Fund

“Vellum has been a force multiplier for our AI efforts; their test-driven approach helps us catch regressions early and iterate quickly. In a space where accuracy and security assurance are critical, Vellum gives us the infrastructure to move fast without compromising performance and deliver AI-powered features that our customers can trust.”
