Where deeptech founders meet the best VCs.
We're a team of 40+ hardware VC funds who rigorously read every submitted deck to find the best. We individually reach out if we're interested in investing. We cover every sector—no idea is too niche. We're not an accelerator, so we take no equity.
Skip to the front of 40+ deeptech VC inboxes
Submit your deck, we'll take a look, and we'll forward the best to investors who invest in your sector. Our guarantee is that we look through every deck.
We're a group of 40+ hardware VCs who've built Deep Checks for the benefit of the community. We're one of the largest deeptech funding platforms, with hundreds of millions of dollars invested. We cover every sector within hardware—no idea is too niche. We write checks between $250K and $10M each.
For each great deck we receive, we write a one-pager explaining why our VCs should care. We stake our name on this small set of hardware companies and put them in front of the best-fitting funds. Because of how much time we put into pitching you, Deep Checks is far more effective than cold emailing VCs.
Why submit? Getting in front of this many qualified VCs at once pressures them to move fast—and that helps you close quicker and get a higher valuation. Further, by getting a check from one of us domain expert VCs, we help validate to VCs that you're among the best. Better yet, there's no program to attend—so you give up zero equity.
Testimonials
Deep Checks facilitated the second check into Samara Aerospace, and one of the most important. Early capital is the hardest to secure, and they moved quickly and decisively when it mattered most. Since then, the team has checked in regularly and made introductions without ever being asked. They are incredible partners to have.
Deep Checks helped us connect with one of our investors, who then opened the door to the broader Silicon Valley investor ecosystem, which has been particularly valuable as we expand in the US. Deep Checks has been an incredibly helpful and easy-to-use resource for us, and we’re very grateful for the role it played in our fundraising journey.
My experience with Deep Checks was great. The team was highly engaging, communicative and genuinely supportive throughout, and the platform helped us connect with investors who were a strong fit for what we’re building. We've raised $2.2M so far, some of which from Deep Checks investors!
Since being featured in Deep Checks, The Renatural has raised $6.2 million across our pre-seed and seed rounds. Deep Checks meaningfully changed The Renatural’s fundraising trajectory. At a pivotal stage, the platform cut through the noise and introduced us to thoughtful, high-integrity investors who understood both the technical ambition of our robotics platform and the scale of the market opportunity.
Our 1M pre-seed came together quickly since being featured on Deep Checks. As two founders fresh out of our PhDs, we booststrapped and cold-emailed hundreds of VCs. Most of the meaningful conversations we had came from Deep Checks. After submitting our deck to Deek Checks, we consistently had a few meetings each week with investors who were genuinely interested in deep tech, and we eventually connected with one of our current investors through the platform. I would recommend every deeptech founder to try Deep Checks!

Questions?
What is Deep Checks—in one sentence?
A free, curated matching platform that puts strong deeptech decks in front of 40+ specialist deeptech VCs who actively invest in your specific niche and stage, all at the same time, without an accelerator, a program, or any equity given up.
How is this different from just cold-emailing VCs?
Two ways. First, deeptech VCs are hard to map—most invest in only a few narrow subsectors, and their websites rarely make that clear, so founders waste weeks guessing who would actually be a good fit. Deep Checks has already done that mapping across every sector. Second, for the strongest decks, our team writes a custom one-pager for each relevant investor. A warm, contextualized one-pager lands very differently from a cold inbound, which is why this tends to outperform emailing VCs yourself.
Who should submit?
Companies building something physical: hardware, robotics, chips, materials, energy, batteries, space, defense, transportation hardware, agriculture, food, medtech hardware, quantum hardware, climate hardware and biotech. Any geography. Any stage from pre-incorporation and pure idea through prototype, post-accelerator, and revenue. No company is too early. Your target valuation must be $30M or below. Lower valuations get more attention.
Who should not submit?
Pure software companies (and that includes standalone AI models and most crypto plays) and pure pharmaceutical (drug) startups unless they’re pharmaceutical platform plays. Your product needs a physical component. The submission form also asks you to confirm a credible path to $100M+/yr in revenue within a few years, since the investors here are looking for venture-scale outcomes.
What actually happens after I submit?
Every deck is reviewed—that's the guarantee. Decks are looked at in batches roughly every 2-3 weeks. The team surfaces the strongest decks to thesis-fit investors with a custom write-up. Interested investors then email you directly. There's no group investment decision and no program to attend.
What does it cost? What's the catch?
It's free, and no equity is taken. Deep Checks was built by deeptech fund Julian Capital as a contribution to the deeptech community, and the network of participating VCs benefits from higher-quality, pre-contextualized deal flow. The effort works because everyone in the loop wants the same thing: good deeptech founders meeting the right investors faster.
What are my odds of investors reaching out?
Roughly 30% of founders who submit get contacted by at least one investor. If you don't hear from anyone, it means no investor was interested this time around.
Will I get feedback on my deck?
The goal of the platform is to route deals rather than critiquing them. We don’t offer feedback. For help strengthening your pitch, however, use the sector-by-sector pitch guides on the guides section of our site.
Who sees my deck, and is it confidential?
The Deep Checks VCs on the site, their fund staff, and a rotating set of additional pre-vetted VC partners the team is trialing for inclusion. All are required to keep submissions confidential. You can email our team at any time to have your deck pulled, for any reason.
How should I prepare before submitting?
At minimum, have a clean deck and, ideally, a longform memo. In your traction answer of the submissions page, don't paste a generic company summary—our team already writes the summary for investors. Instead, use that space to show concrete evidence of demand: revenue, LOIs, pilots, or a sharp argument for why demand exists. Make sure every URL you share has open view access; restricted links and tracking-style short links get rejected.
I'd rather join a deeptech startup than fund one. Can you help?
Yes. There's a separate Deep Checks reverse job board: you describe the sectors and kinds of companies that excite you, and Deep Checks matches you against its database of deeptech startups. It's free, and you can resubmit about once a week.
Who's behind it, and who do I contact?
Deep Checks was created by Julian.capital, a deeptech seed fund, with key operational support from two other funds: UndeterredCapital.com (Joe Wilson) and HumbaVentures.com (Leo Polovets). Specifically, Jacob Jackson (video) and John Forbes (video) from Julian Capital run the admissions process. For founder questions: decks@deepchecks.vc. For site problems: john@deepchecks.vc.

Mythos invested $1M into Heritable Ag through Deep Checks
Once I submitted to Deep Checks, my email started blowing up with DocSend deck view notifications. It felt like hundreds of them.
I booked meetings with a dozen firms and closed my round way oversubscribed within 2-3 weeks of submitting.
GreenLIB's entire $1.5M pre-seed was filled through Deep Checks
Fundraising can be such a black box. Deep Checks helped open it up for us. We didn’t just get names - we got warm, well-matched intros to investors who actually got what we were building.
That’s how we landed Undeterred Capital, Humba Ventures, and Julian Capital for our pre-seed. If you’re tired of cold outreach and endless pitch emails, this is the way to go.
