What the Quantum Computing Investor Map Looks Like Right Now
Quantum computing pulls a smaller, more concentrated investor base than most tech categories, and that makes sense once you think about it. Building a working qubit is still mostly a research problem with a business plan attached, so the money clusters around a handful of places actually doing the physics.
In the AngelMatch database, United States investors make up roughly half of everyone tagged to quantum computing, with the United Kingdom a distant second and Germany, Canada, India, Israel, and France rounding out the rest. Inside the US, California carries the biggest share, and San Francisco alone is home to more of them than most entire countries on this list. London and Cambridge do a similar job for the UK, and Munich, Paris, and Toronto each punch above their size, usually because a major quantum research university or national lab sits nearby.
That clustering changes how you should fundraise. You're not going to find quantum-focused investors by casting a wide net across a city's general startup scene. You're more likely to find them by working backward from research institutions like MIT, Caltech, Oxford, and ETH Zurich, all of which keep spinning out quantum hardware and software companies, and then following the money that already backs those spinouts.
Stage-wise, this market skews early. Most investors tagged to quantum computing focus on early stage venture, seed, and pre-seed, and together those three stages make up the vast majority of the list. Series B and later-stage investors show up far less often, partly because the technology is still young enough that most rounds are proving out a qubit modality rather than scaling a finished product, and partly because the handful of companies that do raise big growth rounds tend to pull in generalist late-stage funds and sovereign vehicles that aren't tagged to quantum computing specifically in most investor databases.
How Much Quantum Computing Startups Actually Raise
The canonical numbers you'll see everywhere, angel checks in the $25,000 to $500,000 range and VC checks from $2 million to $100 million or more, still apply here. But quantum hardware pushes toward the top of that range earlier than most categories, because building and testing physical qubits is expensive before you have anything close to a product.
According to The Quantum Insider's 2026 investor roundup, citing the QED-C's State of the Global Quantum Industry report, private venture capital flowing into quantum reached $4.9 billion in 2025, more than double the prior year's record high. US-headquartered companies alone raised over $2.7 billion of that total, well over half the global figure. The single biggest deal of the year was PsiQuantum's $1 billion Series E, led by BlackRock at a $7 billion valuation, the largest private funding round quantum computing has ever seen.
Seed rounds for quantum hardware companies now average close to $10 million, up sharply from around $2 million a few years back, mostly because early prototyping work like cryostats, laser systems, and cleanroom time costs real money before there's anything a customer can touch. Series A rounds for hardware typically land in the $15 million to $40 million range, and Series B rounds often clear $50 million once a company starts scaling manufacturing. If you're building quantum software instead, the numbers are gentler: Series A rounds in the $5 million to $20 million range are common, closer to what a typical enterprise software company raises at that stage.
Non-dilutive money plays a bigger role here than in most categories too. Government programs like NSF SBIR grants, which typically run from $150,000 to $2 million, fund a meaningful chunk of the earliest research before any equity round happens. If your company touches national security, defense, or fundamental physics with a long runway, it's worth lining up grant funding alongside your VC search rather than treating the two as separate tracks.
Who's Writing the Checks: Dedicated Funds, Corporates, and Government Money
Quantum computing has developed something most tech categories don't have yet: a small cluster of venture funds that invest in quantum and only quantum. Quantonation, a Paris-based fund, is the largest of these by assets, investing from pre-seed through Series A across quantum computing, sensing, and related hardware. 55 North out of Copenhagen and Quantum Exponential in the UK run similar dedicated quantum mandates, and Ground State Ventures backs pre-seed and seed quantum companies out of Amsterdam, London, and San Francisco.
Alongside the dedicated funds, a set of deep-tech generalists shows up in nearly every quantum round. Lux Capital, Playground Global, and Andreessen Horowitz have all backed quantum hardware companies from seed through growth, often because a partner at the firm has a physics background and a specific conviction about which qubit modality will win.
Corporate venture arms are unusually active in this market too, and they're not just writing checks. Google Ventures, IBM Ventures, and Microsoft's M12 all hold confirmed quantum positions, and each ties back to a cloud platform, Google Quantum AI, IBM Quantum, or Azure Quantum, that benefits from having portfolio companies building on it. Samsung, Bosch, Airbus, and BMW have also backed quantum companies through their corporate venture arms, usually with an eye on a specific industrial application like materials science or sensing rather than a pure financial return. Treat a corporate strategic investor differently from a normal VC: they tend to move slower, expect closer technical alignment with their internal roadmap, and often exit through acquisition rather than an IPO.
Government and sovereign capital rounds out the picture. In-Q-Tel backs quantum companies for the US intelligence community without the usual VC exit pressure, and sovereign funds like Temasek and Mubadala have taken direct positions in major rounds, including Temasek's participation in PsiQuantum's Series E. If national security or long-horizon deep tech is part of your pitch, these investors are worth researching even if they don't fit the profile of a typical seed check.
Worth noting: government involvement in quantum has been getting more direct, not less. In mid-2026, a new national quantum strategy pushed federal agencies toward faster post-quantum migration deadlines and backed a federally funded quantum computer for scientific research, on top of an existing push toward fault-tolerant computing capability by 2028. None of that shows up as a line item in a pitch deck, but it does mean a founder working on anything adjacent to national infrastructure or scientific computing has more government doors worth knocking on than founders in most other categories.
Where Quantum Computing Overlaps With AI, Hardware, and Cybersecurity
Quantum computing rarely gets pitched as a category on its own. Most of the investors active here also have a thesis in adjacent deep-tech categories, and that's worth knowing before you write your pitch. A corporate venture arm like Samsung or Bosch, for example, is often evaluating a quantum bet alongside its broader hardware and sensing portfolio, not treating quantum as an isolated line item.
Artificial intelligence is the clearest overlap. Several of the corporate strategics active in quantum, including Google and Microsoft, run their quantum and AI investment theses through related teams, since both are seen as long-horizon computing bets with shared infrastructure needs. Cybersecurity is the other close neighbor: post-quantum cryptography, the effort to secure systems against a future quantum computer that can break today's encryption, has become one of the more fundable niches inside the category, and investors who back quantum hardware often have a cybersecurity thesis running in parallel.
If your company sits at one of these intersections, mention it early. An investor who already has a thesis in hardware or AI security will move faster on a company that maps cleanly onto something they already understand, rather than one that requires them to build a new investment thesis from scratch.
What Quantum Investors Want to See Before They Write a Check
Vague claims about "quantum advantage" don't get you very far anymore. Investors in this space expect specific numbers: qubit count against your own roadmap, gate fidelity, coherence times, and error rates measured against competing hardware platforms. If you can't produce those numbers, or you're citing a milestone nobody outside your team has verified, expect that to come up in diligence fast.
Commercialization timeline matters just as much as the physics. A credible path to revenue within three to seven years, whether through hardware sales, software licensing, or a services partnership, is close to a baseline expectation now. The 2025 funding surge didn't loosen that bar. If anything, it raised it: investors are rewarding teams that pair a strong fault-tolerance roadmap with a believable near-term revenue plan, not just impressive lab results.
Team credibility carries unusual weight in quantum, more than in most software categories. A founder with a deep quantum physics research background, or one who's already built and scaled a hardware or software company, gets taken more seriously than a strong deck alone would suggest. Corporate investors in particular look for prior exits or operational experience running deep-tech companies, and government-backed investors weigh peer-recognized scientific credibility heavily. If your founding team is light on that kind of background, a technical advisor with the right research pedigree can do more for your credibility than another slide of projections.
One more thing worth knowing before you start reaching out: who you approach matters as much as how you pitch. A dedicated quantum fund or a government-backed program is a much better first conversation for an early-stage company than a corporate venture arm looking for strategic fit at Series B. Save the corporate conversations for once you have real technical validation behind you, and use AngelMatch's investor database to sort the list by stage before you start sending notes.
Where to Actually Find These Investors
Start with location. The United States carries the largest share of quantum computing investors in the AngelMatch database by a wide margin, and if you're outside the US, United Kingdom-based investors are the next biggest pool, concentrated around London and Cambridge.
Stage is the other filter worth narrowing by. If you're pre-product, pre-seed and early stage venture investors are where most of the activity sits. If you already have a working prototype and are raising to scale manufacturing or move toward Series A, seed-stage funds in this list are more likely to have the check size and risk tolerance you need.
Once you've narrowed the list, treating outreach like a normal fundraising process still works. Build a tracked list, personalize each note to the investor's actual quantum thesis instead of a generic pitch, and follow up on a schedule, which beats sending the same email to everyone tagged to the category. It's a small pool compared to most markets on this site, so a scattershot approach wastes more of your limited targets than it would in a bigger category.
Quantum computing is a small, concentrated market to raise in, and that's actually good news if you approach it deliberately. Knowing which of the roughly 1,000+ investors in this database actually write checks at your stage and in your geography beats emailing all of them. Build your target list around the funds and corporates who've already backed something close to what you're building, lead with real hardware or software metrics, and use AngelMatch's Fundraising CRM to keep every conversation moving instead of losing track of who you've already talked to.
