Deep Tech is busy breaking all sorts of investment records.
It’s halfway through 2025, and the venture market is enjoying a strong rebound. Mega-rounds and a resurgence in IPOs pave the way for a promising new growth cycle.
Volume is down, value is up, and according to Crunchbase News, over a third of all funding in the first half of the year went to just 11 companies.
Deep Tech still dominates. VC funding is currently sitting at an all-time high in Europe, where novel segments alone (including space tech and robotics) account for $7.8 billion.
The U.S. still leads the global market, propelled by the meteoric rise of AI. According to Reuters, startups raised $162.8 billion in the first half of 2025, with AI companies capturing around 64% of total deal value.
Deep Tech continues to prove its VC attractiveness elsewhere, captured by some interesting market shifts. Here are some numbers worth watching this year:
· In Switzerland, Deep Tech accounts for 60% of all VC funding, the largest national share in the world.
· The UK leads Europe in Deep Tech investment, with Cambridge and Oxford continuing to combine cutting-edge university spinouts with record startup funding.
· Germany saw a staggering 61.7% increase in deep tech investment between 2024 and 2025.
· Ireland is quietly building deep-tech momentum: Tech startups raised a record €634 million in Q1 2025, with three companies accounting for over half the total.
· Globally, a 15% surge in M&A value is offsetting the 9% dip in volume, resulting in a tricky-to-navigate environment for dealmakers.
The detail comes alive when you take a closer look at the specific transactions. From mega AI rounds to breakthrough bets in hardware and biotech, here are some of the deals that caught our eye so far this year:
Portal Biotech – UK – $35 Million – Series A
London-based Portal Biotech raised one of Europe’s largest life sciences investments back in July, a $35 million Series A investment led by the NATO Innovation Fund and the Earlybird. The funding will aid the delivery of Portal Biotech’s full-length single-module protein sequencer; the first of it’s kind.
Proxima Fusion – Germany – $150 Million – Series A
Proxima Fusion, a Munich-based energy startup, secured Europe’s largest ever private fusion investment round in June, raising approximately $150 million in series A funding. The investment will be used to develop the world’s first stellarator fusion power plant.
HAYA Therapeutics – Switzerland – $65 Million – Series A
Switzerland’s Haya Therapeutics have raised $65 million in series A funding to advance its precision RNA-guided medicines programme. The funding follows a $25 million seed raised back in 2021.
ZuriQ – Switzerland - $4.2 Million – Seed
ETH Zurich spinout, ZuriQ, raised $4.2 million in seed funding in January to grow its trapped-ion quantum hardware business and push forward its work on next-generation quantum computing.
ProVerum – Ireland - $80 Million – Series B
Dublin-based ProVerum, the developers of minimally invasive medical devices, raised $80 million in a Series B funding round. The funding will support the commercialisation of ProVerum’s novel treatment for men with benign prostatic hyperplasia.
PhysicsX – UK – $135 Million – Series B
PhysicsX are a London-based company that empower engineers with AI-driven, real-time multiphysics simulations, and they rasied $135 million in series B funding in June. The investment will support the growth of its global footprint and the industrial adoption of its enterprise software platform.
Looking to the Future
From trillion-dollar AI buildouts to bold bets in quantum, chips, and even space solar power, 2025 is shaping up as a watershed year for deep tech.
What stands out is not just the size of the capital being deployed, but the breadth of ambition: governments, private equity, and tech giants alike are all racing to secure strategic ground in the technologies that could define the next two decades.
