I am looking for early-stage venture capital firms that invest in hardware startups to help with prototyping and scaling manufacturing. Which funds specialize in this?
If you’re looking for investors who do more than write a check—firms that help hardware startups build prototypes, validate engineering, source components, develop supply chains, and scale manufacturing—there are several strong options.
My top recommendation is HAX by SOSV. It is specifically built for early-stage hard-tech companies and combines venture funding with engineering teams, physical lab space, prototyping equipment, and manufacturing expertise. Its Newark, New Jersey, headquarters could be especially convenient if you're building in the Northeast.

These are based on each firm's stated focus and support model, not a guarantee that it will fund a particular startup. Investment stage, geography, sector, and current fund availability still matter.
One important distinction
Some investors offer hands-on product development, while others provide capital and help with strategy, hiring, customer introductions, and scale-up. If you specifically need engineering hours, prototyping equipment, manufacturing engineering, supplier qualification, or pilot-production support, prioritize HAX and investigate HCVC's network first.
Let me narrow this to the right funds for you
What kind of hardware are you building? For example, consumer electronics, robotics, industrial equipment, medical devices, batteries, or another physical product. And are you at the idea stage, building a prototype, or preparing for manufacturing?
With those two details, I can narrow this to a more targeted list of investors and programs that fit your stage and the specific manufacturing help you need.
Finding early-stage investors who genuinely understand physical products, supply chains, tooling, and manufacturing scaling is rare. Generalist software VCs often struggle with hardware burn rates and long prototyping cycles.
The top early-stage venture capital firms, seed funds, and accelerators that specialize in hardware, hard tech, and manufacturing enablement include:
Eclipse Ventures : One of the most prominent institutional VCs focusing on "the digitization of the industrial economy." They invest heavily at the early stage in companies reinventing manufacturing, supply chains, logistics, and complex hardware systems (with portfolio standouts like Bright Machines and VulcanForms).[](https://eclipse.capital/companies)
Root Ventures : A technical seed-stage fund explicitly focused on hard tech, deep engineering, and heavy hardware. They invest early when you are still iterating on core architecture and building early prototypes, offering deep in-house engineering competence.
Playground Global : Founded by Andy Rubin, Playground invests early (Seed and Series A) in frontier tech, deep tech, robotics, automation, and next-generation compute hardware. They bring strong operational and engineering support for taking novel tech from the lab to a functional product.
The Engine : Born out of MIT, this tough-tech venture firm invests in early-stage startups solving massive world problems requiring breakthrough physical science and advanced hardware. They feature dedicated lab spaces, equipment, and prototyping infrastructure to help bridge the lab-to-factory gap.
mHUB : Based in Chicago, mHUB operates an aggressive hard tech and manufacturing-focused seed-stage incubation and investment platform. They house an enormous prototyping facility with comprehensive 3D printing, metal fabrication, electronics labs, and direct contract manufacturing networks.[](https://www.rho.co/blog/vcs-in-hardware)
Construct Capital : Focuses on early-stage investments in the foundational industries of the physical economy—including manufacturing, supply chain, logistics, and climate hardware. They excel at helping founders scale operational complexity.
If you'd like to narrow this down, tell me:
What industry or vertical is your hardware in (e.g., robotics, climate tech, medical devices, consumer IoT)?
What stage of development are you at (e.g., proof-of-concept breadboard vs. DFM/first tooling)?
I can tell you which of these specific funds aligns best with your current timeline and funding needs.
Eclipse : A prominent early-to-growth stage fund that specifically targets the intersection of technology and physical industries (manufacturing, supply chain, logistics, and hardware). They pride themselves on having an in-house platform team of operators and engineers who actively help founders solve complex industrial and scaling challenges.[](https://www.openvc.app/investor-lists/hardware-investors)
Playground Global : Founded by Andy Rubin and other tech veterans, Playground invests at the Seed and Series A stages in deep tech, frontier tech, and complex hardware. They have an extensive internal team of mechanical, electrical, and software engineers who roll up their sleeves to help portfolio companies transition from prototype to production.[](https://www.openvc.app/investor-lists/hardware-investors)
Root Ventures : A seed-stage fund run by engineers and technical founders. They focus heavily on deep tech, hard science, and heavy-duty hardware/robotics. Because the partners have built physical tech themselves, they offer practical, hands-on guidance through early engineering hurdles.[](https://www.openvc.app/investor-lists/hardware-investors)
The Engine (by MIT): Based in Cambridge, "Tough Tech" is their specialty. They invest from Seed onwards and provide startups working on breakthrough physical systems access to specialized lab space, equipment, prototyping facilities, and a deep network of manufacturing and regulatory experts.[](https://www.openvc.app/investor-lists/hardware-investors)
Yes. For a hardware startup, I’d prioritize investors that can help with engineering, prototyping, design-for-manufacturing, supplier relationships, tooling, pilot runs, and the transition to volume production—not just funds that happen to have hardware companies in their portfolio.
Probably the clearest fit if you're still prototyping. HAX provides up to , physical labs, engineering support, and supply-chain/manufacturing expertise spanning the U.S., Pune and Shenzhen. It explicitly works from prototype → pilot → commercialization.
If manufacturing and supply chain are core to your seed-stage risk, I’d put investors with actual hardware/industrial portfolios and operating expertise ahead of generalist seed funds.
A useful initial shortlist:
root.vc — Seed-focused and built around engineering-heavy companies. Its portfolio includes Fictiv (manufacturing), Instrumental (manufacturing quality/inspection), and other hardware/infrastructure businesses.
constructcapital.com — Particularly relevant if you're in industrial tech, manufacturing, logistics, robotics, or supply-chain infrastructure. Its portfolio includes companies such as Hadrian and Copia.
eclipse.vc — Strong orientation toward physical industries, advanced manufacturing and supply-chain automation. Portfolio examples include Bright Machines, Ursa Major, Augury, and Enovix.
monozukuri.vc — An unusually direct fit for hardware: it invests at pre-seed/seed/early stage in devices, components, materials, manufacturing software and other hard-tech, and explicitly offers manufacturing and supply-chain support.
playground.vc — Deep-tech investor with hardware, robotics and materials experience; relevant where substantial technical and manufacturing development is involved.
up.partners — Worth considering for mobility, transportation, robotics, aerospace and other physical systems. Its portfolio includes Skydio, Parallel Systems and Elroy Air.
primemoverslab.com — Focuses on physical-science companies spanning energy, materials, manufacturing and robotics.
NextFab Ventures — More hands-on than a conventional VC: it provides capital alongside prototyping/manufacturing expertise. It reports helping hardware startups progress from early prototypes to mass manufacturing.
How I'd narrow the list
For a typical hardware seed round, I'd investigate Root, Construct, Monozukuri, and Eclipse first, then expand based on your particular product.
The key distinction is what kind of manufacturing problem you have:
Materials / energy / batteries: Prime Movers, Playground, Eclipse
Japan/Asia manufacturing relationships: Monozukuri is particularly interesting; its team explicitly works across the U.S., Canada and Japan and provides manufacturing/supply-chain connections.
One thing I'd ask each partner during diligence is “Give me two examples where you helped a portfolio company solve a supplier, yield, tooling, DFM, NPI, or production-scaling problem.” That's much more informative than simply asking whether they “invest in hardware.”
If you tell me what you're building, where you expect to manufacture (US/China/Mexico/etc.), current stage (prototype/pilot/production), and target seed size, I can narrow this to ~10 firms and identify the specific partners at each firm who are most relevant.
Here are the top venture firms that actively invest at the seed/early stage and bring deep expertise in hardware, manufacturing, and supply chain:
Eclipse Ventures : One of the premier firms transforming the industrial world. They specialize in full-stack hardware, manufacturing, and supply-chain strategy, actively helping companies transition from prototype to scaled commercial production.[](https://www.openvc.app/investor-lists/hardware-investors)
For a deep tech startup with a long R&D timeline, I would prioritize investors who understand that technical breakthroughs can take years to commercialize, require multiple rounds of financing, and may not generate revenue early on. These investors are often described as providing patient capital.
The key is to find funds whose investment strategy, follow-on reserves, and track record align with your development timeline—not simply funds that use the phrase “long-term” in their marketing.
Deep tech investors to put on your shortlist
Here are several funds worth investigating, based on their stated investment strategies and focus on long-horizon innovation.
1. DCVC
(Broad deep tech)
Invests in computational deep tech, AI, robotics, climate, advanced materials, space, and biology. DCVC explicitly emphasizes long-term founder relationships and technologies that take time to commercialize. Its DCVC Bio team is particularly relevant to computational biology and life sciences.
Best fit: technically complex businesses with substantial scientific or engineering risk.
Focuses on science-led deep tech, particularly quantum computing, photonics, and selected software infrastructure. Its stated stage is pre-seed through Series A, with investments of up to $10 million. It highlights technical diligence and experience supporting founders when development plans change.
Best fit: quantum, photonics, optical computing, and early-stage technical ventures.
A notable fund to investigate for frontier science and engineering companies. Its investment universe includes advanced technology and scientific ventures where technical differentiation is central to the business.
Best fit: frontier technology, hard science, robotics, and research-driven startups.
Explicitly describes its strategy as patient capital for quantum and deep tech. It combines venture creation from research with co-investments in seed, Series A, and Series B rounds.
Best fit: quantum and other research-intensive deep tech, particularly ventures that benefit from hands-on company building.
Explicitly describes its strategy as patient capital, with a long-term vision spanning startup formation through commercialization. It invests in therapeutics and medical technology.
Best fit: biotech, therapeutics, medtech, and health-related scientific platforms.
MSD's therapeutics-focused venture fund backs early-stage, including seed-stage, drug development companies. It emphasizes sustained capital, board-level partnership, and scientific support from concept toward clinical proof of concept.
Best fit: preclinical therapeutics and breakthrough drug platforms, rather than general engineering deep tech.
Traditional venture capital isn't always the best sole source of funding for a 7–15-year R&D program. Depending on your technology, consider:
Strategic corporate investors: Companies with a commercial reason to see your technology succeed may offer investment alongside pilot projects, licensing, or development partnerships.
Government R&D grants and contracts: In the US, programs such as SBIR/STTR can fund technical milestones without immediate equity dilution, subject to program eligibility.
Specialist life-sciences funds: If you're developing therapeutics, Lightstone and MRL Ventures are relevant starting points. For broader biotech venture funding, a16z Bio + Health announced a $500 million fund with Eli Lilly in January 2025, designed to take a long-term view of emerging biological science.
How to tell whether a fund is genuinely patient
When you speak with potential investors, ask:
Fund life: How long can the fund hold investments, and does it have flexibility to extend?
Follow-on capacity: Does it reserve enough capital to finance several rounds before commercialization?
Technical milestones: Will it support progress measured by validated prototypes, experiments, or regulatory milestones rather than revenue alone?
Portfolio evidence: Has it backed companies with comparable R&D timelines, including through delays or difficult financing environments?
Exit expectations: Does it expect a conventional venture exit within a fixed window, or can it support a longer path through strategic partnerships and commercialization?
A fund can be patient about technology while still having a relatively short financial horizon. Ask for concrete examples of how it handled delays in previous portfolio companies.
Let's narrow this to the investors most likely to fund your startup
The best shortlist will depend heavily on your technology and how far you've progressed.

With those details, I can narrow the list to funds with a relevant technical thesis, suitable check sizes, and evidence that they can support a long R&D journey—not just generalist VCs that occasionally invest in deep tech.
Prominent venture funds and organizations well-known for backing long-horizon, tough-tech innovations include:
The Engine (built by MIT) : Explicitly designed to provide patient capital for "tough tech" (climate, human health, advanced infrastructure). They feature an unusually long fund life (up to 18 years) and provide portfolio companies access to specialized shared lab infrastructure and equipment.[](https://www.harvardmagazine.com/2020/10/harvard-invests-in-mit-the-engine)[[2]()](]()]()
My deep tech company has a very long R&D cycle before we can go to market. Can you suggest venture firms that specialize in patient capital for these kinds of extended timelines?
Yes. For a deep-tech company where commercialization may take 7–15+ years, I’d look beyond conventional early-stage VC and prioritize investors whose strategy, fund structure, or portfolio history accommodates extended technical de-risking.
Firms I’d put on the initial outreach list

Why it fits long R&D cycles
Particularly relevant for
DCVC
One of the clearest deep-tech specialists. It invests from incubation/pre-seed through later stages and explicitly describes maintaining reserves to support companies across the long gap between early innovation and market dominance.
I'm looking for investors who understand the extended development timelines of deep tech. Which funds are comfortable with long-horizon research capital?
How do I find VC firms that specifically invest in "hard tech" or deep tech startups with long R&D cycles?
Raising capital for a space tech startup means navigating a mix of dedicated "NewSpace" specialist funds , deep-tech generalists, and corporate/strategic players.
The primary venture capital firms specializing in or actively leading rounds in the space tech domain are organized below by category:
NewSpace Capital – A Luxembourg-based private equity and growth-stage investor targeting the European and broader space ecosystem with a team rich in aerospace engineering backgrounds.
Tier-1 Deep Tech & Frontier VCs (Active Space Core)
Lux Capital – Renowned for high-conviction, early-to-growth "long-shot" deep tech and frontier science bets, with a massive footprint in aerospace, defense dual-use, and orbital infrastructure (e.g., Planet Labs, Varda).
Founders Fund – Famous for early foundational bets on category-defining aerospace giants like SpaceX alongside newer propulsion and defense-tech startups.
DCVC (Data Collective) – Deep tech generalists who heavily back capital-efficient and data-driven space companies, earth-scanning constellations, and orbital logistics.
Andreessen Horowitz (a16z) – Through their American Dynamism practice, they actively invest in aerospace, defense, and hard-tech infrastructure with massive dry powder for scaling rounds.
– Long history of frontier aerospace and satellite infrastructure investing (such as Rocket Lab).[](]()]()
Strategic & Corporate VCs (CVCs)
Airbus Ventures – The corporate venture arm of Airbus, investing globally from Silicon Valley, Paris, and Tokyo into transformative aerospace and space innovations.
RTX Ventures – The venture arm of RTX (Raytheon), focused on aerospace, defense, and advanced-technology solutions.
Yes. If you’re raising for a space-tech company, I’d prioritize investors with actual space underwriting experience rather than simply “deep tech” VCs that happen to have one aerospace investment.
There are several venture capital firms that specialize in space technology, often called SpaceTech or NewSpace investing. They finance companies developing launch vehicles, satellites, in-orbit infrastructure, Earth observation, satellite communications, and other technologies that enable the commercial space economy.
For a focused starting list, I’d prioritize firms whose investment strategies are explicitly dedicated to space, rather than generalist VCs that occasionally invest in aerospace startups.
Leading space-focused venture capital firms
1. Space Capital
(Top U.S. starting point)
A dedicated space investment firm focused on the infrastructure, distribution, and applications layers of the space economy. Its interests include satellite communications, GPS, geospatial intelligence, and related technologies. Portfolio companies include SpaceX, Planet, Rocket Lab, and ICEYE.
Engineer-led seed fund focused specifically on hardware, manufacturing, robotics, automation and semiconductors. Its typical initial investment is $3–5M, so it's particularly interesting if you have meaningful technical/IP risk rather than simply a consumer product.
One of the more hardware-specific funds: its stated focus includes engineering, manufacturing, marketing and financial capital, with an emphasis on the earliest stages of building hardware companies.
Particularly relevant to companies whose product itself changes physical industry. Eclipse has built companies around manufacturing technology and says its venture-equity model brings customer, talent and operational networks to physical-industry startups.
Strong candidate if your hardware touches vehicles, mobility, logistics, robotics, manufacturing or infrastructure. Its portfolio spans manufacturing, robotics, IoT, OEMs and warehouse/logistics, and its current strategy includes seed and early-stage investing.
Especially worth pursuing if you're in Michigan. It explicitly targets advanced manufacturing, mobility, clean energy and hardware, invests at Seed/early stage, and describes its model as hands-on with industry partnerships and operational expertise for commercialization and scaling.
Detroit/Michigan-specific option. Its Detroit Innovate Fund invests $100K–$250K initially with follow-on capital, focused on commercialization and sales scaling; its Michigan Innovation Fund covers pre-seed through Series A and includes advanced manufacturing, materials and mobility.
Not a manufacturing specialist, but it invests extremely early and explicitly includes hardware among its investment clusters. Its active-founder support model can be useful around hiring, GTM and early company-building alongside a more manufacturing-focused investor.
One important distinction
I'd actually build your financing strategy around two kinds of capital:
1. Equity investor: funds R&D, engineering, tooling, hiring and working capital. 2. Production/capex financing: eventually pays for molds, machinery, production equipment and inventory without unnecessarily diluting you.
For the second category, Fountain Partners is worth knowing. It's not an early-stage VC, but it specifically provides non-dilutive equipment financing to manufacturers and hardware businesses, including from first production equipment through scale.
If you're in/around Detroit
I'd put Side Door Ventures + ID Ventures unusually high on your outreach list because Michigan's manufacturing ecosystem can be strategically useful for a hardware company—not merely a source of capital. Pointe Angels is another local possibility; it explicitly invests in early-stage hardware and describes itself as hands-on.
For a company that is pre-prototype, I'd start with HAX/SOSV and Lemnos.
For a company with a working prototype and significant engineering/manufacturing risk, Root is particularly relevant.
For a company approaching pilot production or scaling, I'd broaden toward Eclipse, industry-specific funds, and non-dilutive production financing.
One caveat: Bolt is frequently recommended in older hardware-investor lists, but don't put it on your current fundraising list—the firm says it is no longer making new investments under the Bolt banner.
If you tell me (a) what the hardware is, (b) current stage—idea/prototype/EVT/DVT/PVT/shipping, (c) how much you're raising, and (d) where you're manufacturing, I can turn this into a target list of ~15–25 investors, including likely check size, stage, relevant portfolio companies, and the best partner/contact to approach.
Bolt : A specialized seed/pre-seed fund that explicitly invests in startups combining hardware and software. They are famous for having an in-house engineering and prototyping team that helps founders work through manufacturing bottlenecks.[](https://blog.hardfin.com/venture-capital-firms-that-focus-on-hardware-technology)
Root Ventures : A firm built by engineers for engineers. They invest at the earliest stages of hard tech and hardware development, providing hands-on support for building reliable, scalable systems.[](https://www.openvc.app/investor-lists/hardware-investors)

They run an intensive program providing seed capital alongside a fully equipped prototyping lab and dedicated on-the-ground manufacturing support (frequently interfacing with Shenzhen and US production ecosystems).[](https://www.openvc.app/investor-lists/hardware-investors)
Bee Partners : Often writes the first check at the pre-seed and seed stages for foundational tech, including robotics, industrial automation, and machine intelligence tied to physical workflows.[](https://www.rho.co/blog/vcs-in-robotics)
Lux Capital : Managing multi-billion dollar vehicles (such as their recent $1.5B Fund IX commitments), Lux specializes in turning "sci-fi into sci-fact," investing heavily across physical sciences, deep tech, defense, and life sciences with the conviction required for multi-year horizons.[](https://www.luxcapital.com/news/announcing-lux-ventures-ix)
Prime Movers Lab : Invests in breakthrough scientific startups (energy, transportation, human augmentation, agriculture) that reinvent foundational human industries, explicitly advertising a long-term outlook to match scientific timelines.
Lowercarbon Capital : Focused strictly on climate tech and hard science interventions to slash emissions or remove carbon, managing substantial funds with a high tolerance for regulatory and physical R&D timelines.
Breakthrough Energy Ventures (BEV) : Backed by global titans, BEV was built specifically to finance tough energy and climate transitions that standard 7-to-10-year venture funds cannot support due to protracted commercialization paths.
Strategic Corporate VCs (CVCs) & Sovereign/Gov Funds : Entities like In-Q-Tel (IQT) for national security/defense, or regional entities like the UK National Security Strategic Investment Fund (NSSIF) or various ARPA-E/SBIR/STFC government-backed vehicles, offer non-dilutive or ultra-patient capital aligned with national interests rather than quarterly LP returns.
If you tell me your specific vertical (e.g., nuclear fusion, quantum computing, advanced materials, or biotech) and what funding stage you are at (Pre-Seed vs. Series A), I can help you narrow down the exact funds or non-dilutive grants best aligned with your milestones.
Built around frontier science and technology. Its latest $1.5B fund says it can support companies from the first $100K through the last $100M and across the full company-building arc.

Deep tech, life sciences, Cambridge/UK ecosystem
Arcas Ventures
Calls its strategy "patient capital for impatient founders," investing at pre-seed/seed with follow-on capacity.
European deep tech, materials, space, computational science, medtech
Uniseed
Particularly interesting if you're university/CSIRO-connected. It explicitly defines deep tech around long R&D, IP, manufacturing and regulatory timelines and provides later-stage follow-on capital.
University spinouts, biotech, quantum, advanced materials, energy, robotics, aerospace
"Patient capital" doesn't necessarily mean a 15-year venture fund. Even deep-tech VCs generally operate within finite fund lives. What matters is whether they have:
large follow-on reserves rather than expecting you to raise a new round every 18–24 months;
a demonstrated willingness to fund technical milestones rather than revenue milestones;
experience financing companies through multiple difficult development stages;
partners who understand regulatory, manufacturing and scientific risk;
access to non-VC capital such as government grants, strategic investors and project finance.
DCVC is particularly interesting on this dimension: its own materials emphasize the need for reserves to carry companies from early innovation toward market dominance.
I'd also consider the financing architecture
For genuinely long-cycle technology—say fusion, novel semiconductors, quantum hardware, new materials, advanced therapeutics, aerospace, robotics hardware, or industrial biotech—I wouldn't necessarily try to fund the entire R&D period with ordinary VC.
A stronger structure can be:
VC + non-dilutive R&D capital + strategic/corporate capital + eventual project/growth financing.
That lets the VC fund company-building while grants and strategic partners absorb some of the expensive technical development. The right investor therefore isn't merely "who has the longest holding period?" but who has successfully assembled this capital stack before?
One interesting caution: Lux itself has explicitly argued that some technologies with 15–20-year commercialization timelines don't fit conventional VC economics, despite being a major deep-tech investor. www.luxcapital.com That's a useful reminder that even excellent deep-tech VCs may want to see a credible sequence of intermediate value-creating milestones.
If you tell me (1) your technology/sector, (2) current TRL or development stage, (3) how many years until first commercial revenue, and (4) roughly how much capital you need before that point, I can narrow this to 5–8 specific funds and identify the partners/investors who are most relevant to your particular technology, rather than giving you a generic deep-tech list.
Prominent venture firms and specialized funds known for providing patient capital to deep tech, hard tech, and long-timeline R&D ventures include the following:
Prime Movers Lab : Invests in breakthrough scientific startups inventing transformational technologies (energy, longevity, manufacturing, and transportation). They explicitly position themselves as long-term partners capable of supporting companies through extensive scientific validation and commercialization.
Breakthrough Energy Ventures (BEV) : Backed by a coalition of global investors, BEV finances cutting-edge innovations in clean energy and climate technology. They are purpose-built for multi-decade timelines, recognizing that decarbonization technologies require extensive R&D and infrastructure scale-up.
Founders Fund : Known for making contrarian, high-conviction bets on hard tech, aerospace, and defense (e.g., SpaceX, Anduril ). They have a long-standing appetite for foundational technologies that require an extended runway before market entry.
Foundry : Frequently structures their approach to support foundational ecosystems and longer-term innovation horizons, often operating with structural flexibility compared to traditional fast-turnaround SaaS funds.
This is probably the cleanest specialist target if you're building a commercially oriented space business. Founded in 2012, it now reports $1B+ AUM across four institutional funds and invests across infrastructure, distribution and applications. Its portfolio includes companies such as SpaceX, Planet, Rocket Lab, Impulse Space and ICEYE.
Probably the most obvious specialist investor if you're looking for a fund whose identity is SpaceTech. Seraphim describes itself as a specialist SpaceTech investor and has backed 150+ SpaceTech startups, including ICEYE, D-Orbit, LeoLabs, Xona, Skylo, Pixxel, AST SpaceMobile and Tomorrow.io. Its latest early-stage fund closed above $100M in 2026 and targets Seed/Series A globally.
Don't overlook the "space-adjacent" mega-specialists
Depending on what you're building, I'd also approach Lux Capital, DCVC, Founders Fund, Khosla Ventures, General Catalyst and Andreessen Horowitz's American Dynamism practice. They aren't pure-play space funds, but can be much better leads for companies where space intersects with defense, AI, robotics, autonomy, semiconductors, energy or industrial infrastructure.
For example, Lux explicitly categorizes investments under Physics + Aerospace and has backed Anduril. www.luxcapital.com DCVC is a deep-tech specialist with a long history of investing in technically difficult, capital-intensive technologies.
One important distinction
The best investor depends enormously on what kind of space company you are:
🚀 Launch / propulsion → Space Capital, Seraphim, Airbus Ventures + deep-tech/defense VCs
🛰️ Satellite / spacecraft hardware → Seraphim, Airbus Ventures, Space Capital
The sector is also getting considerably larger: Seraphim's latest tracker reports $23B invested in SpaceTech over the 12 months through Q2 2026, with 620 deals.
If you tell me your company's stage (pre-seed/Seed/A/B), what you're building, where you're headquartered, and roughly how much you're raising, I can turn this into a targeted list of ~20 VCs ranked by fit, including the specific partner at each fund you should approach.

If you are looking for funding or research, let me know:
What stage is your project or company (pre-seed, seed, Series A+)?
