Namespace raises $42M Series B for AI coding infrastructure
Zurich's Namespace raised $42M from Scale Venture Partners, NEA and 20VC after growing revenue 8x in a year - proof the compute behind AI-written code is becoming the prize infrastructure layer.

Founded 2022 · Zurich, Switzerland
Namespace, the Zurich company building the compute layer where software gets built, tested and shipped, has raised a $42M Series B led by Scale Venture Partners, with NEA, 20VC, Essence, Burst Capital, Susa Ventures and angels including Datadog CEO Olivier Pomel joining the round.
Europe has watched its developer-tool talent drift towards the Bay Area for a decade – and yet the build farm the AI era runs on is, for now, operated from Zurich. The round, announced on Monday 5 October 2026, is one of the sharpest European Series Bs of the autumn: large, fast, and priced off numbers rather than narrative.
Seven months from Series A to a $42M cheque
The facts first. Namespace raised $42M in Series B funding led by Scale Venture Partners, with NEA, 20VC, Essence, Burst Capital and Susa Ventures participating, alongside angel investors including Olivier Pomel, CEO of Datadog (company announcement, 5 October 2026). It comes seven months after the company disclosed $23M in combined seed and Series A funding led by NEA in March 2026, and takes the total raised to $65M.
The money goes where the queue is. Namespace will accelerate product development and expand its own data centre footprint – including the fleet of Mac hardware it runs for Apple-platform builds – and open offices in San Francisco and New York (announcement, 5 October 2026). The numbers behind the cheque: revenue up 8x over the last twelve months, with more than 1,000 organisations on the platform, among them Ramp, Framer, ElevenLabs, Vanta and Warp.
“Namespace is the platform that can meet demand for speed and scalability while delivering reliability and security,” said Scale Venture Partners’ Javier Redondo in the announcement. Harry Stebbings of 20VC was blunter: “Namespace has the best customer references we’ve ever encountered in 12 years of investing.”
Nine years inside Google, then everyone’s build farm
Founder and CEO Hugo Santos spent nine years as a principal engineer at Google, where he helped build Boq, the internal development platform behind Search, YouTube and Workspace (company site). In 2022 he founded Namespace in Zurich to sell what Google engineers take for granted: fast, secure compute for building, testing and running code.
In practice that means cloud CI runners that slot into GitHub Actions, ephemeral development environments, and remote build caching for Docker, Bazel and Turborepo – across Linux, macOS and Windows (company site). The Series B framing adds the part investors paid for: Namespace positions itself as the infrastructure layer for AI coding agents, because every agent-written pull request still has to compile, build and pass its tests on a real machine somewhere.
It is the same thesis that carried Restate’s $20M Series A for durable execution last week: as agents write more of the code, the unglamorous machinery around the code becomes the scarce asset.
A $1.67bn CI market compounding at 21% a year
The segment Namespace sells into is still small and moving fast. The global market for continuous integration tools stood at $1.67bn in 2025 and is forecast to reach $9.33bn by 2034, a 21.06% CAGR over 2026-2034 (Straits Research, updated August 2026). Add the compute bill that AI agents generate every time they iterate on a branch, and the addressable spend grows faster than the tooling line alone.
Set against our own records, the amount is the outlier. Recent European developer-infrastructure rounds include Restate’s $20M Series A led by Singular (September 2026) and Clastix’s €2.9M seed led by CDP Venture Capital (September 2026). A $42M Series B lands at twice the Restate cheque, seven months after the A – at a 21% market CAGR, that pace says the investors are underwriting the agent wave, not the historical CI market.
Why the agent era pays infrastructure first
What are we actually seeing here? US capital reaching into European software for the third time in a week: Scale Venture Partners leading in Zurich, days after Insight Partners led Metaview’s $60M Series C in London. The reality is familiar – the growth cheques still carry a Bay Area letterhead, and Namespace’s new offices are opening in San Francisco and New York, not Paris or Berlin.
The good news is what stays. The headquarters, the engineering and the data centres remain European, and Zurich has quietly become one of Europe’s best addresses for infrastructure software – the ETH pipeline and Google’s long-standing engineering presence in the city have seen to that. I keep hearing that Europe cannot do infrastructure; the term sheet above says otherwise.
What to watch: whether the cohort behind Namespace – Restate, Clastix and the rest of Europe’s developer-infrastructure bench – converts to B-rounds on anything like this timetable, and whether agent-driven compute demand keeps compounding for anyone else at 8x a year. Our fundraising data will show it quarter by quarter.
Europe does not need to copy the Bay Area to win this layer; it needs to keep building the machines the agents run on. Zurich just showed how that gets funded. Keep shipping.
