Drumbeat Capital just released the largest Deep Tech report in the world - 461 pages covering funding, talent, exits, robotics, AI, energy, and the transatlantic bridge between the U.S. and Europe. Data powered by Dealroom and Carta, with contributions from investors at Founders Fund, Lux Capital, Eclipse, General Catalyst, Lightspeed, and many others.
Here are the takeaways I think matter most for founders, investors, and operators building in physical AI, robotics, and industrial tech.
Deep Tech is no longer an alternative asset class. It IS the asset class.
50% of all U.S. venture capital funding now goes to Deep Tech. In Europe, it's 26% and growing.
7 of the 10 most valuable companies in the world started as Deep Tech companies - from Nvidia (GPU computing) to TSMC (chip manufacturing) to Tesla (reinventing the automobile). This has been consistent for 50 years. The biggest companies in every era commercialized scientific breakthroughs.
The combined enterprise value of Deep Tech startups globally has reached $3.9 trillion.
Funding is at record highs - but the distribution is extremely uneven
Total Deep Tech venture funding in the U.S. and Europe hit $156.6B. The U.S. makes up 80% of that.
At the seed stage, the U.S.-Europe gap is 2x. By Series C+, it balloons to 16x. European Deep Tech startups aren't failing to start - they're failing to scale. Europe has actually overtaken the U.S. in the number of Deep Tech rounds. The dollars just aren't there at growth stage.
The Bay Area hosts only 16% of Deep Tech startups but captures over 50% of all capital raised. Capital concentration remains extreme.
Graduation rates tell a clearer story than fundraising totals
U.S. Deep Tech companies raise subsequent rounds at significantly higher rates than both Regular Tech and European Deep Tech:
- Seed to Series A: 39% (U.S. Deep Tech) vs. 22% (Europe Deep Tech) vs. 28% (U.S. Regular Tech)
- Seed to Series D+: 13% (U.S. Deep Tech) vs. 5% (Europe Deep Tech)
U.S. Deep Tech companies are also 1-2 years faster at reaching each funding milestone. And the median time to unicorn in the U.S. is almost half of what it is in Europe.
Deep Tech companies are 2x more likely to reach Series D than Regular Tech companies. This is a structural advantage, not a bubble.
Robotics funding has tripled in the U.S.
The robotics section is where this report gets most interesting for our community.
U.S. robotics venture funding has tripled. Europe has doubled. The top 10 U.S. robotics rounds in 2025 include Project Prometheus ($6.2B), Figure ($1B), Physical Intelligence ($600M), Apptronik ($415M), Agility Robotics ($400M), Field AI ($314M), and Hadrian ($260M).
Haomiao Huang from Matter Venture Partners - one of the sharpest voices in physical AI investing - put it well in the report: "The robots of the past were capital equipment. The robots of the future are not just products, they are distribution channels for services powered by Physical AI. The best robot companies to come will have the potential to combine the innovation and massive market sizes of hardware companies like SpaceX and Tesla with the profit margins and enduring stickiness of the SaaS titans of the past."
The report identifies three key bottlenecks in robotics:
- Data, not compute, is the real constraint. The largest manipulation models train on a tiny fraction of the compute used by frontier language models - not because of chip shortages, but because there simply isn't enough real-world training data. The fix is a blend of internet-scale priors, teleoperation, and simulated/world-model-generated data.
- The sensor and hand bottleneck. Robot dexterity is limited less by how hands move than by how little they feel. Recent breakthroughs in high-resolution touch sensing are starting to change this.
- Vertical vs. general-purpose. The central strategic question: one general-purpose robot that learns any task, or specialized machines optimized per industry? Evidence that robotics foundation models follow the same scaling laws as language models has strengthened the general-purpose camp.
China is dominating humanoid unveils - 51 in 2024 alone vs. 8 from North America and 4 from Europe. But 56% of those platforms are chasing "general purpose," which tells you how early and fragmented the market still is.
The transatlantic bridge is a structural advantage, not a nice-to-have
The report's central thesis is that the next category-defining Deep Tech companies will be built by teams that bridge the U.S. and European ecosystems. The data backs this up:
- Europe produces 2x more STEM graduates than the U.S.
- European tech employees stay 2x longer at their companies
- European Deep Tech salaries are 2-5x lower
- 50% of top technical universities are in the U.S., 30% in Europe
- 44% of U.S. unicorn founders were born outside the U.S.
But 89% of European Deep Tech exit value leaves the continent - mostly to U.S. acquirers. The European ecosystem produces world-class talent and research. The U.S. ecosystem provides scale capital and exit markets. Companies that connect both have a structural edge.
Exits: 90% M&A by count, 60% IPO by value
2025 was a record year for Deep Tech M&A - led by Nvidia's $20B acquisition of Groq, SoftBank's $6.5B acquisition of Ampere Computing, and Marvell's $3.3B acquisition of Celestial AI.
90% of Deep Tech exits by count are M&A. But 60% of exit value comes from IPOs and SPACs. The takeaway: M&A provides liquidity for most companies, but the outsized returns come from going public.
U.S. exit rates are 2x higher than Europe at later stages - again reinforcing the scaling gap.
Energy: the binding constraint nobody's talking about enough
Novel Energy is the section that surprised me most.
The grid itself has become the binding constraint on AI growth. There's a severe shortage of conventional transformers, and a meaningful share of planned data centers are at risk of delay from grid limitations.
Hyperscalers are now directly underwriting nuclear power - both fission (SMRs, restarted plants) and fusion - through long-term purchase agreements. Commonwealth Fusion Systems raised $863M, X-energy raised $1.4B across two rounds, TerraPower raised $650M.
Advanced geothermal has quietly become one of the most credible sources of firm, around-the-clock clean power - importing horizontal drilling techniques from the shale industry to tap heat almost anywhere.
And solid-state transformers built on wide-bandgap power electronics are emerging as the fix for grid bottlenecks, replacing bulky legacy units with compact devices that feed high-voltage DC straight to AI racks.
What I'd add to the conversation
The report is excellent on macro trends and capital flows. A few things I'd layer on from the operator side:
Revenue is still the signal. The report includes a benchmarking table from SVB showing median revenue at each stage (median $220K at Seed, $2.5M at Series A, $6M at Series B, $14.6M at Series C). For physical AI companies specifically, I'd argue the deployment story matters even more than the revenue number - how many units in the field, what's the data flywheel, what does the path from pilot to production contract look like.
The data bottleneck in robotics is creating an entire infrastructure layer. Companies building training data pipelines, simulation environments, and synthetic data generation are becoming as important as the robot companies themselves. This is a theme we're tracking closely at Optim.
The "Deep Tech is a moment in time" framing is smart. Deep Tech isn't a sector - it's the stage where a founding team decides to turn a discovery into something deployable (TRL 4-6). Some of today's Deep Tech will be tomorrow's Regular Tech. The investment window is finite.
