NetBox Labs secures $35 million in Series B funding to expand its open source infrastructure management platform used by enterprises, AI data centers, and government agencies. The company continues to deliver rapid product innovation, including AI-driven tools like NetBox Operator and NetBox Assurance. With a growing global team and strong investor backing, NetBox Labs reinforces its role as a core component in managing complex digital infrastructure.
Why NetBox Labs Attracts Major Investment Again
NetBox Labs secures $35 million in Series B funding, led by NGP Capital. New investors Sorenson Capital and Headline participate alongside existing backers, including Notable Capital, Flybridge, Two Sigma, Salesforce, Mango, and IBM. This round follows the company’s $20 million Series A announced just over two years ago. The funding is expected to accelerate development and expand capabilities across its infrastructure management offerings.
Since its spin-out from NS1, NetBox Labs has rapidly scaled its product portfolio, customer base, and team, now nearing 100 staff globally. The company’s open source roots and focus on delivering operational value to critical infrastructure teams continue to attract significant investor confidence.
How NetBox Labs Becomes a Backbone for Critical Infrastructure
NetBox has become the global standard for infrastructure management. It supports large-scale AI data centers, Fortune 500 companies, government agencies, and global service providers. These organizations use NetBox Labs products to operate, document, automate, and secure network and infrastructure systems.
Customers rely on NetBox’s comprehensive data models and open ecosystem to manage everything from enterprise networks to industrial control systems. By acting as a source of truth, NetBox provides teams with structured, validated infrastructure data that aligns operational intent with execution.
Inside the NetBox Stack: What Makes It So Widely Adopted
NetBox Labs offers multiple infrastructure management solutions:
- NetBox: Open source platform serving as a source of truth
- NetBox Cloud and NetBox Enterprise: Hosted solutions that include advanced features like change management and CMDB integration
- NetBox Discovery: Enables automatic infrastructure detection
- NetBox Assurance: Identifies and addresses configuration drift
- NetBox MCP server: AI-powered capabilities released in 2025
- NetBox Operator: Upcoming agentic AI product designed for autonomous infrastructure management
Product updates are released every one to two weeks. All major features and tools are developed in collaboration with a large group of design partners, reinforcing alignment with customer needs.
AI Is Changing Everything—NetBox Labs Plans for It
The company has introduced AI features that expand its infrastructure management approach. NetBox now serves as a semantic map for AI systems to analyze and act on infrastructure data. This contextual mapping supports advanced automation, risk detection, and infrastructure decision-making.
In 2025, NetBox Labs launched the MCP server and is preparing the release of NetBox Operator. This agentic AI solution is designed to navigate infrastructure autonomously, with NetBox as its knowledge base. The shift toward AI-enablement reflects rising demand for intelligent automation in complex environments.

The Open Source Flywheel That Keeps Gaining Speed
NetBox Labs follows a self-reinforcing investment model known as the “virtuous circle.” Revenue from commercial products is used to support open source projects through direct development, full-time engineering hires, and ecosystem support.
This strategy ensures NetBox’s continuous growth while remaining freely accessible. Projects like Diode (for data ingestion) and Orb (for observability) are maintained by dedicated NetBox Labs teams. The company encourages extensibility and integration with other infrastructure tools, avoiding vendor lock-in.
NetBox Labs also follows a “Big Tent” philosophy, promoting compatibility with diverse infrastructure management stacks. This approach has helped drive rapid adoption and active collaboration across the community.
Inside the Four C’s of Infrastructure Management Maturity
NetBox Labs describes infrastructure improvement using a framework called the “4C’s”:
- Coverage: Establishing a comprehensive inventory across systems
- Confidence: Ensuring data accuracy by detecting drift
- Cohesion: Unifying fragmented tools and systems
- Control: Using intent-driven automation to manage change and scale operations
Organizations often progress through these stages non-linearly, driven by specific initiatives such as audits or hardware refreshes. Users like CoreWeave, ARM, JPMorgan Chase, and Riot Games have used the NetBox stack to reduce costs, improve security, and accelerate infrastructure automation.
Why NetBox Labs Says the Journey Is Just Beginning
Founded in 2023, NetBox Labs is building long-term infrastructure for automation, observability, security, and operations. Its tools are increasingly used in environments where scale, accuracy, and resilience are mission-critical. Community feedback and design partner input guide every major release.
The company emphasizes its “community-first” value and continues to support public projects with commercial backing. Open roles across engineering and product teams indicate plans to grow rapidly alongside the expanding ecosystem.
With ongoing investment and increasing customer adoption, NetBox Labs plans to further develop the core NetBox platform and deliver infrastructure solutions that meet the complexity of modern digital systems.
