Namespace, a developer-infrastructure company that runs compute for software builds, tests and development environments, has raised a $42m Series B led by Scale Venture Partners. The company announced the round on its blog on 5 October 2026.
NEA, 20VC, Essence, Burst Capital and Susa Ventures also took part, along with angel investors including Olivier Pomel, chief executive of Datadog. The round comes seven months after Namespace's NEA-led Series A and brings its total funding to $65m. No valuation was disclosed.

What Namespace does
Namespace was founded in Zurich in 2022 by Hugo Santos, a former principal engineer at Google, according to Tech.eu. It wants to be the infrastructure layer for AI coding agents, starting with coding and continuous integration (CI), the automated building and testing of code every time it changes.
Its products include devboxes, which are remote development environments for AI coding agents; a drop-in replacement for GitHub Actions; and support for build tools such as Docker, Bazel, Turborepo and Nix. It offers Mac, Windows and Linux environments, including Mac machines for iOS and macOS development. The Namespace Platform is vertically integrated, with its own hardware, hypervisor and scheduler.
Customers and growth
Namespace says more than 1,000 companies use its service. Customers named in the announcement include Ramp, SpaceXAI, ElevenLabs, Factory, ClassPass, Framer, Zed, Verkada, fal.ai, Buildkite, Vanta, Sierra, Warp, DuckDB and Mapbox.
The company said its total revenue grew eight times over the past 12 months, but it did not give revenue figures. It describes its team as lean and has not disclosed its headcount.
Harry Stebbings, founder of 20VC, said in the announcement that the company had the strongest customer references his firm had seen in 12 years of investing. Aloke Desai, head of product engineering at customer Warp, said in the same announcement that Namespace was the best developer infrastructure tool he had used in years.
What the money is for
Namespace said it will use the money to speed up product development and to expand its own data centre and server capacity, including its fleet of Mac hardware. It did not say how much of the $42m will go to hardware or set out hiring plans.
Owning its compute stack is central to the company's pitch. Tech.eu described the product as aimed at engineering teams that want faster development without managing their own infrastructure, and Namespace positions that same stack as the place where AI coding agents build, test and run code.
The funding so far
The Series A, led by NEA, closed about seven months before the Series B. Namespace did not state its size in the announcement. Together, the company's rounds now total $65m, so the Series B accounts for almost two-thirds of the money it has raised.
Scale Venture Partners led this time, while NEA, which led the Series A, put in more money alongside 20VC, Essence, Burst Capital and Susa Ventures.
