Namespace raises $42M Series B for dev infra

Namespace said on October 5, 2026, that it closed a $42 million Series B led by Scale Venture Partners, with participation from NEA, 20VC, Essence, Burst Capital, Susa Ventures and angel investor Olivier Pomel. The Zurich-based company said the financing brings total funding to $65 million, after a Series A about seven months earlier.

The startup builds bare-metal build, test and sandbox infrastructure for human developers and coding agents. Namespace says its platform combines custom hardware, its own hypervisor and scheduler, and products that include Devboxes and a GitHub Actions replacement. Independent reporting described the company as a specialized developer-infrastructure and compute provider serving coding, build and test workflows across Mac, Windows and Linux, including AI agent use cases.

What does Namespace sell to developers?

Namespace sells compute infrastructure designed for software development workflows that need fast, isolated environments. The company says it runs AI agents, developer tools, CI, container builds and testing workloads, and that its cloud is purpose-built for ephemeral storage, high-speed networking and cache support. SiliconANGLE reported that the service is intended to let software engineers move faster through the software lifecycle, while Tech.eu said the company wants to be the infrastructure layer for AI coding agents so developers and agents can build, test and run code faster.

Namespace also says it designs and deploys its own server racks worldwide, and that its platform spans custom hardware, a hypervisor and a scheduler. The company says one of its products is a drop-in replacement for GitHub runners.

Why is the company emphasizing Mac capacity?

Namespace says demand for its Mac environments has been overwhelming, and that coding agents need Mac capacity with Apple developer tooling at scale. The company said the new funding will expand its data-center capacity, including its Mac hardware fleet.

SiliconANGLE reported that Namespace supports Apple operating system versions including Sonoma, Sequoia, Tahoe and Golden Gate, and that its Mac environments can provide up to 12 virtual CPUs and 56 gigabytes of memory. The same report said Namespace is investing in Mac architecture because more applications are built for macOS and Apple hardware. Namespace also said iOS and macOS app-building agents need Mac environments with the required Apple developer tooling.

The company’s focus on Mac infrastructure reflects a broader bet that conventional cloud virtual machines are not optimized for coding, build and test workloads. Namespace said hyperscalers such as AWS and GCP are not optimized for the workloads it targets.

What is driving the recent growth?

Namespace says demand has increased rapidly and that total revenue grew eightfold over the past 12 months. That revenue figure is company-reported and the supplied reporting does not include independently audited financials.

The customer list suggests the company has already pushed beyond early-stage experimentation. Tech.eu reported customers including SpaceXAI, Ramp, Framer, ElevenLabs and Vanta, while AT Partners said Namespace works with more than 1,000 organizations and also named Bilt and Sierra among them. Warp’s head of product engineering said Warp runs everything from CI to its cloud agent platform Oz on Namespace.

The company was founded in 2022 by former Google engineer Hugo Santos, whom Tech.eu identified as a former Google principal engineer. Santos said Namespace’s vision is to make better developer infrastructure the default for fast-moving companies, starting with coding and CI.

How will Namespace use the new funding?

Namespace said it plans to use the capital to accelerate product development and expand its data-center capacity, including its Mac hardware fleet. Tech.eu reported the company will expand its own compute and server operations, while AT Partners said it will add data-center capacity and open offices in San Francisco and New York City.

Scale Venture Partners partner Javier Redondo said AI agents in software development change prior tooling tradeoffs, and that Namespace can meet demand for speed and scalability while keeping reliability and security. Those comments fit the company’s core pitch: that modern coding and CI workloads need infrastructure built for developer workflows rather than general-purpose cloud instances.

Axios separately reported the round after CEO Hugo Santos disclosed it, and Sesamers listed the deal on October 5, 2026. Namespace said the financing supports its attempt to build the infrastructure layer for AI coding agents as software development becomes more automated.
