European venture funding held up decisively this week, with more than €280 million flowing into a mix of AI-native, defence-tech, deeptech and fintech companies. The pattern is familiar — AI continues to dominate headlines — but the spread of stages and sectors this week gives a clearer picture of where capital is actually moving in 2026. From a $130M late-stage deeptech round for a space-to-AI infrastructure company to a scrappy €1.7M pre-seed for an AI moderation startup, Week 15 was a reminder that European venture is still placing bets across the full maturity curve.
Two themes stand out. First, AI is no longer a category — it is infrastructure across construction, security, diagnostics, personal care and enterprise workflows. Second, sovereign and defence-adjacent tech is quietly racking up serious funding momentum, with European LPs and funds increasingly comfortable backing dual-use technologies. Here are the deals that mattered.
The Deals
AirHub closed a €4.4M Series A to scale its mission-critical drone operations software for Europe’s defence and security sector. The Dutch company builds the fleet-management and counter-drone infrastructure that European public-safety and defence buyers are scrambling to deploy in 2026. Read the full AirHub story.
Trent AI raised a $13M seed to bring agentic AI security to enterprise workflows — a category that barely existed 18 months ago but is now attracting some of the largest seed cheques in Europe. As companies roll out autonomous agents, the attack surface multiplies, and Trent AI is betting that securing agents will be a standalone market. More in our Trent AI deep dive.
Handhold secured €3M in seed funding to automate B2B software sales with AI account managers — attacking the fragmented buying journeys that make enterprise procurement so painful for both vendors and buyers. Read more on Handhold.
Audicin picked up $1.9M to scale its brainwave-based nervous system regulation technology, pushing the boundary of consumer neurowellness beyond meditation apps. Full story on Audicin’s raise.
Pickmybrain raised $2.1M to let domain experts monetise their knowledge through AI-powered “Digital Brains” — a creator-economy play that sits at the intersection of expertise marketplaces and generative AI. Details in the Pickmybrain article.
Penemue closed €1.7M to scale AI-powered hate speech detection across European languages — a timely raise given tightening EU regulation around online harms and platform accountability. See the Penemue announcement.
Xoople delivered the week’s largest deep-tech headline with a $130M raise to build Earth’s AI data infrastructure from space. The company is positioning itself as a foundational layer for Earth-observation intelligence, with applications from climate monitoring to defence. Full coverage in our Xoople Series B piece.
Covalo raised €3.5M to build the data backbone for the personal-care industry — a B2B ingredients and formulation platform that has quietly become critical infrastructure for beauty and skincare brands. More in our Covalo story.
Octostar closed €6.1M to scale its sovereign AI intelligence platform across Europe — a clear vote of confidence in the “European stack” narrative that is driving procurement decisions in the public sector. Read the full Octostar coverage.
Finally, Upvest closed a landmark $125M Series D to modernise Europe’s investment banking infrastructure — one of the biggest European fintech rounds of the year so far, and a signal that investor appetite for embedded-finance infrastructure has not cooled. Full analysis in our Upvest Series D article.
Sector Themes
Three patterns jump out from Week 15’s activity.
AI has become horizontal infrastructure. The AI label applies to seven of this week’s ten deals, but the use cases are strikingly diverse: drone operations, enterprise security, B2B sales, neurowellness, knowledge monetisation, content moderation, and sovereign intelligence. This is the maturation curve we have been watching for the past year — AI is no longer a destination sector but the default architecture for new companies across every vertical.
Defence and sovereignty are structural, not cyclical. AirHub, Octostar and arguably Xoople all touch dual-use or sovereignty-adjacent markets. The investor base for these rounds is expanding beyond specialist defence funds — generalist European VCs are now comfortable writing cheques in a space that would have been off-limits three years ago.
Fintech infrastructure is back. Upvest’s $125M round is the headline, but the broader message is that the “picks and shovels” layer of European finance — custody, clearing, embedded infrastructure — is once again a priority area for growth capital. That is a meaningful shift from the 2024-25 fintech winter.
Looking Ahead
Week 16 will be the first real post-Q1 reporting period, and we expect a cluster of follow-on raises from companies closing out Q1 milestones. Watch in particular for more activity in climate-tech and energy-transition deals — two spaces that were relatively quiet this week but have strong pipelines heading into Q2. Expect at least one European unicorn crowning by month-end.
