Infrastructure Investments, Strategic Exits, and Digital Sovereignty Define European Tech's Latest Evolution
A $225 million Series A for a Swiss chip-interconnect company. A €1.3 billion exit for a Swedish-founded music rights platform. A coalition of European firms launching an open-source office suite to reduce dependency on Microsoft. And a former German AI CEO pulling an Apple engineer across the Atlantic.
These are not disconnected headlines. Read together, they trace the contours of a European tech ecosystem that is maturing in specific, measurable ways – and revealing where the structural bets are being placed.
The Hardware Layer Gets Serious
Kandou AI's $225 million Series A stands out not just for its size – one of the largest Series A rounds in European deeptech this year – but for what it signals about where capital sees bottlenecks forming. The Lausanne-based company focuses on breaking memory bottlenecks in AI systems, a problem that becomes more acute as model sizes grow and inference demands scale.
This is infrastructure-layer investment. Not applications, not wrappers, not chatbots – but the physical and architectural constraints that determine what AI systems can actually do at speed and at scale. The round positions Kandou at the intersection of semiconductor design and AI acceleration, a space where European players have historically been sparse.
The timing matters. As hyperscalers and AI labs push toward larger models and more complex reasoning chains, memory bandwidth and interconnect efficiency become binding constraints. Kandou's bet is that solving these problems at the chip level creates defensible value – and that Europe can host such companies if the capital is willing to show up early and at scale.
It did.
Exits as Ecosystem Signals
The €1.3 billion sale of Kobalt, the Swedish-founded music rights management platform, offers a different kind of signal. Exits of this magnitude remain relatively rare in European tech, and each one recalibrates expectations – for founders, for investors, and for the talent pool that watches where liquidity actually materializes.
Kobalt's trajectory – from Stockholm origins to London operations to a billion-euro-plus exit – illustrates a pattern worth tracking: European companies that build global platforms in underserved verticals can reach scale, but the path often involves geographic arbitrage and patient capital. The music rights space, long dominated by legacy players and opaque structures, proved receptive to a technology-first approach.
For the ecosystem, the exit matters less as a single data point than as a reference class. It expands the set of plausible outcomes for founders building in adjacent spaces – media infrastructure, creator economy tooling, rights management – and it returns capital to investors who may redeploy it into the next generation of European startups.
Sovereignty as Product Strategy
Perhaps the most structurally interesting development this week is the launch of Euro-Office, a coalition-backed open-source office suite designed to offer full Microsoft format compatibility under European governance.
The coalition includes IONOS, Nextcloud, Eurostack, XWiki, OpenProject, Soverin, Abilian, and BTactic – a mix of infrastructure providers, collaboration platforms, and open-source specialists. A tech preview is available immediately, with a stable release planned for summer.
The framing is explicit: digital sovereignty. As IONOS CEO Achim Weiss stated, "With the geo-political developments we have seen in the last year, there is a clear need for a reliable, fully Microsoft-compatible and easy-to-use sovereign office solution in Europe."
The context is instructive. ONLYOFFICE, a previously popular alternative, recently shut down its cloud offering, forcing organizations to reassess their setups. Euro-Office positions itself as a response to this gap – not just a feature-for-feature competitor, but a structurally different offering: open-source licensing, no trademark constraints, transparent governance, and a contributor community open to public scrutiny.
Whether Euro-Office achieves adoption at scale depends on execution – specifically, on whether it can deliver the "seamless handling of widely used document, spreadsheet and presentation formats" it promises, with an interface that "minimises retraining and migration friction." The technical building blocks exist; the question is whether the coalition can assemble them into something that public administrations, enterprises, and educational institutions will actually deploy.
Frank Karlitschek, Nextcloud CEO
Europe has had the technical building blocks for years. What was missing until now was an initiative to bring them together into a meaningful, comprehensive solution.
Talent Flows and Founder Recycling
The announcement that Jonas Andrulis, former CEO of Aleph Alpha, has launched a new startup called CNTR adds another data point to the European AI talent map. Andrulis left Aleph Alpha last year after six years leading the high-profile German AI company, which itself pivoted from building large language models (LLMs) to helping businesses and governments deploy AI.
CNTR – named after "centaur chess," where humans and computers play together – is developing what it calls "collaborative AI systems." The premise: in industrial environments, automated AI systems alone are insufficient, and human judgment remains critical. The technology enables AI agents to ask humans clarifying questions, helping mitigate hallucinations.
The startup is backed by Roland Berger, the German consultancy, and has recruited Alejandro Molina, an Apple engineer, to relocate from the US West Coast to Germany as CTO. Molina previously worked at Amazon and Aleph Alpha.
This is founder recycling in action. Andrulis brings operational experience, investor relationships, and a network of technical talent. The ability to pull a senior engineer from Apple to Germany suggests that European AI startups can compete for talent when the mission and the team are compelling enough.
Investor Moves Worth Watching
The week also brought notable fund announcements. Nathan Benaich's Air Street raised $232 million for Fund III, becoming Europe's largest solo GP venture firm. futurepresent emerged from stealth with a $300 million Fund I focused on AI across infrastructure and industry. Credo Ventures raised $88 million for Fund 5, targeting pre-seed in Central and Eastern Europe and its global diaspora.
And Hiro Capital disclosed that it invested around €50 million in AMI Labs, the world model startup founded by Yann LeCun, as part of a $1 billion-plus raise. Hiro co-led the round alongside Cathay Innovation, Greycroft, HV Capital, and Bezos Expeditions.
Luke Alvarez, Hiro Capital Managing General Partner
We have done one investment in world models. We probably won't do more of those. We are really interested in applications of those world models, in things like autonomy and robotics. We certainly don't think there is much opportunity to invest at this point in competitors to Anthropic and OpenAI for language and code foundation models.
This is capital allocation discipline. The foundation model layer is consolidating; the application layer is where European investors see differentiated opportunity.
What the Week Reveals
Taken together, the week's developments suggest a European AI ecosystem that is:
- Investing in infrastructure: Kandou's round reflects a willingness to fund hardware-layer companies at scale.
- Generating meaningful exits: Kobalt's €1.3 billion sale expands the reference class for European founders and investors.
- Building sovereignty-oriented alternatives: Euro-Office represents a coordinated attempt to reduce dependency on non-European platforms.
- Recycling founder talent: Andrulis's new venture shows that experienced operators are staying in the ecosystem and building again.
- Deploying capital with discipline: Investors are increasingly explicit about where they see opportunity – and where they don't.
The aggregate funding tracked this week – more than 55 deals worth over €850 million, plus over 15 exits and M&A transactions – reflects an ecosystem that is active, liquid, and increasingly differentiated.
The question is whether these signals compound. Infrastructure investments take years to mature. Sovereignty initiatives require adoption at scale. Founder recycling depends on the next generation of companies reaching meaningful outcomes.
The mechanisms are in place. The capital is flowing. The talent is circulating. What remains to be seen is whether Europe can convert these inputs into durable competitive position – not just in applications, but in the layers beneath them.
For those tracking these dynamics closely, the conversation continues in Vienna on May 19 at Human x AI Europe, where the people shaping these trajectories will be in the same room.
