Namespace has closed a $42 million Series B for a developer cloud built around the work between writing code and shipping it. Engineering teams and AI coding agents use its remote environments to check out repositories, load toolchains, build software and test changes instead of keeping every working environment on a developer’s laptop.
A coding agent often needs the result of a build or test before it can decide what to do next, turning execution time into part of the programming loop. Namespace provisions isolated devboxes with the relevant code and tools, then carries useful cache and state across iterations. It also offers hosted GitHub Actions runners and remote execution for Bazel builds.
Namespace doesn’t stop at software orchestration. It operates its own server racks and selects the processors, NVMe storage and networking beneath the service, while its platform handles scheduling and data placement. Native Apple silicon environments let developers and agents build and test iOS and macOS software on Mac hardware, alongside Windows and Linux work.
The company says more than 1,000 organizations use the platform and that revenue grew eightfold over the past 12 months. Its disclosed customer roster includes Ramp, ElevenLabs, ClassPass, Vanta and Warp; Warp says it runs both continuous integration and its Oz cloud-agent platform on Namespace.
Scale Venture Partners led the round, with NEA, 20VC, Essence, Burst Capital and Susa Ventures participating. The closing came seven months after Namespace’s Series A and brings total funding to $65 million. Namespace plans to use the new capital for product development and additional data-center capacity, including more Mac hardware—physical expansion that follows directly from operating the computing stack itself.
