NGP Capital Leads $35M Series B in NetBox Labs to Accelerate AI Data Center Deployments

NetBox Labs has successfully closed a $35 million Series B funding round led by NGP Capital, with participation from Sorenson Capital, Headline, and existing backers such as Flybridge Capital, Notable Capital, Mango Capital, Salesforce Ventures, Two Sigma Ventures, and IBM.

The company serves as the commercial steward of NetBox, an open-source network and infrastructure management platform that has become the industry standard for modern technology operations. This platform currently supports tens of thousands of enterprises worldwide, including numerous Fortune 500 companies, hyperscalers, AI startups, and government organizations who rely on NetBox for critical infrastructure management.

NetBox Labs has developed a comprehensive suite of solutions designed to address the growing complexity of modern networks. Their portfolio includes NetBox as the core system of record, NetBox Discovery for automated network detection, NetBox Assurance for infrastructure monitoring, and NetBox Operator, which leverages AI for network operations. These tools work together to help organizations deploy AI data centers more efficiently, often reducing deployment timelines by weeks.

The funding comes at a time when infrastructure demands are surging due to AI adoption across industries. Companies like CoreWeave have experienced significant benefits from using NetBox Cloud to accelerate their AI datacenter deployments. The platform's automation capabilities enable faster infrastructure deployment, which directly impacts revenue generation for rapidly growing technology companies.

"There's a race to expand and modernize the complex infrastructure that keeps every aspect of today's digital world quick, resilient, secure, and manageable," explained Kris Beevers, co-founder and CEO of NetBox Labs. "NetBox is now a ubiquitous platform at the heart of a composable network and infrastructure management stack, with adoption soaring even more as AI drives massive demand for infrastructure."

NGP Capital's investment reflects confidence in NetBox Labs' market position and growth potential. "NetBox Labs represents a powerful convergence of open-source innovation and enterprise-scale network automation, positioned perfectly to address the expanding needs of complex, modern networks," said Upal Basu, Partner at NGP Capital. "Their impressive commercial growth validates our belief that they can become the de facto platform for network operations, observability, automation, and security."

CoreWeave's experience demonstrates the practical value NetBox provides to infrastructure-heavy organizations. "We're building dozens of new AI data centers every year, full of complex infrastructure," noted Jim Julson, head of network at CoreWeave. "NetBox is crucial for accelerating our timelines with automation. Deploying our infrastructure even a month sooner as a result of these efficiencies directly impacts our revenue."

The Series B funding builds on NetBox Labs' previous $20 million Series A round raised in 2023. The company plans to use the new capital to accelerate innovation and scale operations to meet increasing global demand. This expansion includes hiring across multiple departments including customer success, engineering, marketing, product development, partnerships, and sales.

NetBox Labs has experienced remarkable growth, with their globally distributed team quadrupling in size over the past two years. The company maintains a strong focus on community engagement, fostering a vibrant ecosystem of contributors, partners, and technology integrations that continues to drive platform adoption and innovation.

The platform's success stems from its ability to make sense of increasingly complex networks and infrastructure environments. As organizations worldwide continue replacing legacy infrastructure management tools with modern, cohesive solutions, NetBox has emerged as the preferred choice for companies seeking reliable, scalable network operations capabilities.
