$42m · Series B · AI · Zurich, Switzerland
Namespace has raised $42m in Series B funding to expand the compute infrastructure used to build and test software. The Zurich company said Scale Venture Partners led the round, with NEA, 20VC, Essence, Burst Capital, Susa Ventures and angel investors including Datadog CEO Olivier Pomel participating. The financing brings total funding to $65m and will support product development and a larger data-centre footprint, including more Mac hardware.
Coding agents turn build latency into infrastructure demand
Namespace provides development environments, continuous-integration runners, remote build execution and caching across Linux, Windows and macOS. Its Devboxes give coding agents isolated computers with repositories, tools and credentials, while its GitHub Actions product replaces hosted runners with compute designed for build and test workloads.
The commercial mechanism becomes clearer as agents run in parallel. Generating code may be fast, but an agent often needs a build or test result before deciding what to do next. Slow queues and cold environments therefore hold up each iteration, and more concurrent agents multiply the demand for isolated machines, cache reuse and predictable execution. Scale Venture Partners argues that this breaks assumptions behind infrastructure designed for human-paced workflows; Namespace is betting that specialised developer compute becomes a recurring operational expense as agent activity grows.
The company controls more of that stack than a software-only runner service. It says it designs and deploys its own server racks, with processors, NVMe storage, networking, a hypervisor and scheduling software tuned for development workloads. That can improve performance and data placement, but it also makes growth capital-intensive: customer demand has to arrive quickly enough to keep specialised capacity productively used.
Mac capacity widens the platform's role
Apple development is a concrete example of the infrastructure gap. iOS and macOS builds require Apple hardware and toolchains that many general-purpose cloud providers do not offer at scale. Namespace plans to expand its Mac fleet, positioning the same platform to serve both coding agents and mobile teams that need native environments.
Namespace reports that revenue grew eightfold over the past twelve months and that more than 1,000 organisations use its platform, including Ramp, ElevenLabs, Framer, Vanta, Warp and DuckDB. On its product site, customers report faster queues and builds, alongside lower CI costs; those figures are company-published case studies rather than standardised benchmarks, but they show that buyers are paying for shorter feedback cycles rather than raw compute alone.
The round now funds a capacity-and-reliability test. Owning infrastructure can differentiate Namespace on speed, Mac availability and integration with developer workflows. It also raises the cost of forecasting demand and maintaining service quality across a larger fleet. The company will need its reported customer growth to translate into durable utilisation while coding-agent workloads are still changing quickly.
