Flox, a leading platform enabling unified software lifecycles, announced it has secured $25 million in a Series B funding round, enabling the company to accelerate product development and market expansion as organizations struggle to manage increasingly complex software supply chains.
The funding round was led by Addition, with participation from NEA, the D. E. Shaw group, Hetz Ventures, and Illuminate Financial.
AI is generating more code than ever, security vulnerabilities are hiding in mounting complexity, and the current infrastructure is simply not built for this scale, according to the company.
Flox solves this by making the power of Nix—the open-source technology behind one of the world's largest package repositories—accessible to engineering teams through an intuitive platform that delivers consistent, portable environments across various operating systems, languages, and architectures.
“The extreme pressure on engineering teams has made standardized development infrastructure a necessity,” said Ron Efroni, CEO and co-founder of Flox. “While everyone else is building on top of broken foundations, Flox is strengthening the foundation itself, enabling teams to move faster without sacrificing trust.”
Early adopters of Flox’s platform range from Fortune 5 enterprises to high-growth tech companies such as Arcesium, Fellow.ai, Neo4j, PostHog, and Weaviate.
"Flox takes the power of Nix and makes it accessible for all," said Flox advisor and distinguished engineer Kelsey Hightower. “That’s why we're seeing an influx of engagement compared to traditional developer tools, they're solving the hidden infrastructure crisis every company faces.”
The Series B funding will also accelerate innovation across three core initiatives:
- Universal development infrastructure: Building the foundation for cross-OS, cross-architecture, and cross-language compatibility, so teams and agents code consistently without environment friction
- Compliance and policy management: Developing automated frameworks and software policies for governance at scale as code volume increases
- Zero-CVE security infrastructure: Providing real-time vulnerability detection with comprehensive SBOMs and SLSA compliance for unprecedented visibility into human and AI-generated code
Flox will also double down on engineering and go-to-market hiring to meet customer demand and expand its enterprise footprint, the company said.
