Quantum fundraising is its own sport. You're not just selling "a startup"—you're selling a physics roadmap, a capital strategy, and a believable path from lab reality to commercial advantage.

When preparing your pitch to quantum investors, having a professional data room is essential. Peony helps quantum startups organize investor materials with AI-powered document organization, track investor engagement with page-level analytics, and securely share sensitive technical and financial data. With transparent pricing at $40/user/month, Peony delivers enterprise-grade secure data rooms without the $5,000-20,000 per-deal costs of legacy platforms.

This guide focuses on investors with real quantum presence (specialist funds, deep-tech leaders, and a few strategic/public investors that consistently show up in serious quantum rounds). No generic VC tourists.

1) How to pick the right quantum investors (the fit test that saves months)

Step 1: Know what kind of "quantum company" you really are

Investors pattern-match hard here. Put yourself in one of these buckets:

  • Hardware / systems (superconducting, trapped-ion, photonics, neutral atoms, cryo/control stacks)
  • Error correction + runtime (QEC stacks, compilers, control, verification)
  • Quantum networking (interconnects, entanglement distribution, quantum repeaters)
  • Software / algorithms (simulation, optimization, chemistry, ML—often hybrid)
  • Sensing & metrology (timing, gravimetry, imaging; sometimes nearer-term revenue)

Your target investor list should be different for each.

Step 2: Match capital intensity to the investor's appetite

Quantum has two common financing "shapes":

  • Capital-light (software / tooling / error correction): faster iteration, earlier revenue, clearer seed/Series A metrics.
  • Capital-heavy (hardware / systems): longer timelines, more infrastructure, heavier syndicates, more patience.

A fund that loves "picks-and-shovels" may be skeptical of "build the computer" (and vice versa). DCVC explicitly describes its quantum approach as largely picks-and-shovels investing (with exceptions). (DCVC)

Step 3: Choose investors whose platform matches your bottleneck

In quantum, your bottleneck is usually one of:

  • recruiting elite quantum talent
  • lab access / fabrication partners
  • error rates / scaling plan
  • customer discovery for the first real use case
  • government / defense relationships
  • ecosystem credibility (partners, standards, cloud access)

Your "best" investor is the one that unlocks the bottleneck—not the one with the fanciest logo.

Step 4: Prioritize "fresh dry powder" and visible activity

Look for:

  • new funds / new closes (faster decisions, more follow-ons)
  • recent deals in quantum categories
  • published theses that match your wedge

Example: Quantonation publicly announced the first close of its second quantum tech fund (Quantonation II) targeting €200M, and stated it is already investing globally from that fund. (Quantonation)

2) Detailed info on the top 10 quantum investors (2025)

1) Quantonation (France/US-active) — the specialist benchmark

Why founders care: Quantonation is one of the most globally recognized quantum-dedicated VCs, and "specialist credibility" matters a lot in quantum rounds.

What they invest in: Quantum technologies and deep physics, with a stated seed-stage focus. (Planet First Partners)

Proof of activity / dry powder: Quantonation announced the first closing of Quantonation II, targeting €200M, and said it is already investing globally from the new fund. (Quantonation)

Founder-useful pitch angle:

  • Lead with the physics wedge + the commercial wedge (not one or the other).
  • Show why your roadmap makes the "useful quantum" timeline shorter for a specific class of problems.

2) DCVC (US) — deep tech leader with explicit quantum strategy

Why founders care: DCVC has long built a reputation for frontier tech, and they publish their thinking clearly.

What they invest in (quantum): DCVC states its approach has been to back "picks and shovels" companies supporting quantum systems, with portfolio examples like Q-CTRL, and notes Rigetti as an exception (they invested in a quantum computer builder too). (DCVC)

Why they're great for founders:

  • If you're building enabling infrastructure (control, verification, middleware), DCVC's framing can be a strong match.
  • They also signal long-term conviction in quantum as a foundational computing shift. (DCVC)

Pitch angle that works:

Bring a "picks-and-shovels" narrative: who are you selling to, what's the budget owner, and how do you become a standard part of quantum stacks?

3) Playground Global (US) — "big-swing" deep tech with quantum in the core

Why founders care: Playground is one of the most respected deep-tech firms for ambitious bets.

Quantum proof points: Playground's portfolio highlights PsiQuantum as a "million qubit quantum computer" effort. (Playground) PsiQuantum itself announced a $1B Series E in 2025 for utility-scale fault-tolerant quantum computing sites. (PsiQuantum)

Best fit for:

  • capital-intensive hardware or system-level plays
  • teams aiming for "category-defining" outcomes, not incremental tools

Pitch angle that works:

Tell a credible story about industrialization: supply chain, fab partners, timelines, and what "useful" means (and how you'll prove it).

4) Lux Capital (US) — frontier VC with real quantum exposure

Why founders care: Lux consistently backs "hard science" companies and has a long history with frontier hardware.

Quantum proof point: Lux publicly lists Rigetti Computing as a portfolio company building a cloud quantum computing platform. (Lux Capital)

Best fit for:

  • quantum hardware, control stacks, enabling physics tech
  • founders who can frame quantum as part of a broader "computing + physical world" shift

Pitch angle that works:

Make the market concrete. Lux responds well when you can connect deep science → product → a huge, real customer budget.

5) Amadeus Capital Partners (UK/EU) — AI + quantum + advanced computing, early-stage friendly

Why founders care: Amadeus is one of Europe's best-known early-stage tech investors with explicit quantum language.

Quantum presence: Amadeus states it invests in "AI, quantum and advanced computing pioneers." (Amadeus Capital)

Recent signal: Amadeus published about Nu Quantum's $60M Series A for quantum networking/distributed quantum computing. (Amadeus Capital)

Best fit for:

  • quantum networking, distributed architectures, enabling layers
  • startups that can show measurable progress pre-revenue (benchmarks, fidelity, integration wins)

Pitch angle that works:

Highlight scalability: how your approach unlocks modular growth (like classical networking did for data centers).

6) IQ Capital (UK) — deep tech VC active in quantum deals

Why founders care: IQ is one of the UK's best-known deep tech VCs and shows up in real quantum financings.

Quantum proof points: IQ Capital lists Nu Quantum in its portfolio. (IQ Capital) Industry coverage of Nu Quantum's Series A also names IQ Capital among the existing investors. (DatacenterDynamics)

Best fit for:

  • UK/EU quantum startups, especially where Cambridge/Oxford talent pipelines matter
  • enabling tech (networking, error correction, systems software)

Pitch angle that works:

Anchor on "shortening the timeline to commercially relevant quantum"—show exactly how your product compresses that timeline.

7) In-Q-Tel (IQT) (US) — strategic investor where defense/national security is relevant

Why founders care: IQT is a strategic investor tied to the US national security ecosystem; for some quantum categories, that's a major accelerator.

Quantum signal: IQT's portfolio taxonomy explicitly includes "Microelectronics & Quantum" categories and lists companies under it. (IQT)

Best fit for:

  • quantum sensing, comms, security-relevant hardware, and enabling microelectronics
  • companies where public-sector adoption is a realistic early path

Pitch angle that works:

Be specific about mission outcomes and deployment constraints (supply chain, sovereignty, reliability). Don't hand-wave.

8) Parkwalk Advisors (UK) — Cambridge spinout machine with quantum credibility

Why founders care: Parkwalk is a powerhouse in UK university spinouts, which is a primary source of quantum talent and IP.

Quantum proof point: Parkwalk lists Riverlane (quantum error correction / "operating system for error-corrected quantum computers") in its portfolio under "Quantum Computing." (Parkwalk Advisors)

Best fit for:

  • Cambridge/Oxford/UK-linked quantum startups
  • error correction, systems software, and deep-tech commercialization paths

Pitch angle that works:

Make your academic roots an advantage—but show you can ship like a company (hiring plan, productization, customer pipeline).

9) Oxford Science Enterprises (UK) — Oxford spinout investor with quantum exposure

Why founders care: OSE is one of the most visible university-linked investors globally, and Oxford is a quantum hotspot.

Quantum proof point: OSE features Oxford Quantum Circuits in its portfolio (explicitly framed as quantum computing). (Oxford Science Enterprises)

Best fit for:

  • Oxford-linked quantum startups
  • teams translating serious academic IP into products

Pitch angle that works:

Show that the spinout is "de-risked": clear IP assignment, a product roadmap, and partnerships that prove credibility beyond papers.

10) Bpifrance (France) — major deep-tech backer showing up in real quantum mega-rounds

Why founders care: For Europe-based quantum, Bpifrance is often the difference between "great research" and "global-scale company."

Quantum proof points:

  • Alice & Bob's €100M Series B announcement lists Bpifrance as a participant and describes Future French Champions as a partnership between QIA and Bpifrance. (Alice & Bob)
  • Polytechnique's coverage also states the round included Bpifrance via its DeepTech 2030 fund. (École polytechnique, école d'ingénieur)

Best fit for:

  • French/EU quantum hardware and core systems plays that need serious capital and national-scale support
  • companies where sovereign capability and industrialization are part of the story

Pitch angle that works:

Tie your roadmap to industrial outcomes: manufacturing, jobs, sovereignty, and a credible path to a European champion.

3) 5 quick tips to pitch quantum investors (and not get politely ghosted)

  1. Show your "physics milestone ladder." Investors want to see 3–5 technical milestones that de-risk the next round (error rates, fidelity, scaling approach, integration, stability). Make it measurable.

  2. Translate quantum performance into buyer value. Even if you're pre-revenue, you should know: who pays first, why they pay, and what success looks like (speedup, accuracy, cost reduction, security).

  3. Be explicit about what you're not doing. Quantum investors respect focus. If you're not building full-stack hardware, say so. If you are, show why that's necessary and defensible.

  4. Make your "go-to-market before quantum advantage" plan real. Many winning quantum companies sell enabling layers (tooling, control, networking, error correction) before full fault tolerance. DCVC's "picks and shovels" lens is a good mental model to address directly. (DCVC)

  5. Bring the diligence pack like a grown-up lab founder. Have ready: IP status, patents/licensing, key hires, supplier dependencies, experimental data rooms, security posture, and a realistic budget tied to milestones. Use a professional data room like Peony to organize materials with AI-powered organization and track investor engagement with page-level analytics.
