Zurich-founded developer infrastructure startup Namespace Labs Inc. today announced it raised $42 million in Series B, led by Scale Venture Partners, to give developers powerful compute infrastructure to speed up software engineering work.

NEA, 20VC, Essence, Burst Capital and Susa Ventures also joined the round. The round comes just seven months after the company’s Series A, led by NEA, bringing total funding to $65 million.

Founded in 2022 by former Google engineer Hugo Santos, Namespace delivers a specialized compute stack for developers that runs artificial intelligence agents, developer tools, continuous integration, container builds, testing and more at lightning speeds. This lets software engineers move faster through the software lifecycle because the underlying compute can keep up with demand.

As AI agents become more pervasive in coding, the coding lifecycle has gotten tighter. Even as DevOps and continuous delivery and integration cycles shorten the time from feature to deployment, testing cycles have squeezed the way that software is delivered, sometimes down to the smallest feature request – often developers work on micro-versions where multiple tiny changes are wrapped up daily or weekly and then pushed into production.

The 2025 DORA Report, run by Google LLC’s Cloud division, found that 16.2% of respondents deployed on demand, 6.5% deployed between hourly and daily, and 21.9% deployed between daily and weekly.

This is generating constant labor and an appetite for compute that can handle the speed needed to build, validate, test and deploy while maintaining quality. Generic cloud virtual machines may handle the durability question, but they’re not generally built with developer tools in mind; they must be configured and constantly monitored and they are often sold with enterprise scale in mind, not developer needs.

To handle the role and purpose of development, Namespace purpose-built its compute cloud for ephemeral storage, running with high-speed networking and cache support.

Additionally, the company is investing in Mac architecture. An increasing number of applications are built for MacOS and Apple Inc. hardware and run on iPhone and MacBook. Many of today’s infrastructure providers skip Mac, which means that most developers building for iOS or macOS have to go to specialized providers.

The company said the new funding will help it expand its data centers, including its fleet of Mac hardware. The company supports multiple OS versions, including Sonoma, Sequoia, Tahoe, and Golden Gate, and can handle up to 12 virtual central processing units and 56 gigabytes of memory.

Namespace currently supports build and test environments across Mac, Windows and Linux.
