AI Development Needs a Standard. We’ve raised a $20m Series A to build it.
Today, I’m thrilled to share that we’ve raised $20M to bring rigor, speed, and reliability to AI development. The round was led by
@leadersfund, with participation from
@ycombinator,
@sociicapital,
@RebelFund_VC,
@pioneer_fund and
@eastlinkcap. It’s a big milestone for us, but more than anything, it validates what we’ve been seeing on the ground: the need for a standard approach to bring AI products into production, especially inside large, complex organizations.

The promise of AI is real. But real AI powered products are still rare.
Why? Because building with LLMs today feels like writing software in quicksand:
- What works in a demo often breaks in production because models behave unpredictably
- The pace of change makes it nearly impossible to stay current, let alone build with confidence (agents weren’t mainstream until just 6 months ago!)
- Everything falls on engineers, making them the main bottleneck
@SiddSeethepalli,
@FlahertyNoa and I felt this pain firsthand, and Vellum is the platform we wish we had when doing our AI development.
Teams at Redfin, Drata, Swisscom and Headspace use Vellum to power mission critical AI systems. Not demos, real apps in production built using our test-driven development philosophy.

I remember someone asking me in Month 2 of our company, “What’s your vision of Vellum?”
My answer back then holds true today: “We’ve lived the AI development pain first-hand so our customers don’t need to. We will be the best-in-class platform engineering teams around the world rely on to power core AI applications.”
Today we are grateful to partner with
@Gideonhayden, and the team at
@leadersfund to scale what we have shown works time and time again.
We’re building not just software, but the standard of how the world builds AI products.
Over the next few days we’ll be sharing some exciting new case studies and launching a huge new feature every day, so follow along for updates!

Huge thank you to our team, customers, and investors, especially
@bradflora and
@_puneetKumar for working with us since the early days in YC. We’ve been building toward this moment and there’s an exciting journey ahead. The path to billions of ARR continues 🚀 🚀
