Skip to the front of 25+ VCs' inboxes

We guarantee our analyst goes through your deck slide-by-slide. The best decks are then passed to the investors below. We want no founder to go overlooked.

We're the most efficient way to get in front of deeptech VCs with priority—more so than emailing them—because we explain to them why your startup is so interesting after we review your deck. We're also the only way to get in front of deeptech founders who angel invest, like the CEOs of Solugen and Astranis.

By getting a check from one of us domain experts, we help validate to other VCs that you're the best in your space, which increases momentum when fundraising.

STEP 1

Submit your deck

Submit a deck within a minute. We prefer $15M valuations and below. All deep tech is welcome.
STEP 2

We'll review it

Every 2 weeks, our funds' analysts look through decks to surface the most interesting ones.
STEP 3

We'll email you

If an investor is interested, they'll email you. We don't invest as a group. Checks are $100K-$5M+.

FAQ

Which startups should submit?

Any deeptech sector, e.g. hardware, biotech, space, robotics, chips, materials, and energy. Please do not submit traditional SaaS/software decks.

All geographies are welcome.

Your valuation must be ~$20M or below. Lower valuations get more attention from us.

What happens after I submit?

If we like your deck after we review it, we will highlight it to our team above and compel them to seriously look at it.

Our investors individually reach out to founders if they're interested. We don't invest as a group; we each have our own fund. If you don't hear from us, it means no individual investors were interested.

Note that we don't provide feedback on your deck submission—we just route deals to the investors.

Deep Checks is the most efficient way for startups to get in front of VCs with priority—more so than emailing them directly—because we explain to them why your startup is so interesting after we review it.

How can we get you to talk at our university?

Fill out this form to let us know you're interested.

Is there a program to attend?

There is no program and nothing to do beyond submitting your deck and/or memo. This website is simply a way to get into multiple investors' inboxes with priority, and to lessen the chance of your deck being overlooked.

Who sees my deck?

The investors on this site, their fund staff, and an additional 25+ VC fund partners we're trialing for inclusion into the group. If founders tell us they have good experiences with the additional VCs, we keep them on. Our goal is to maximize the number of intros we get you—so long as it's to VCs we know and trust. We aim to constrain it to active investors who focus on deeptech and write sizable checks.

Who's the team behind Deep Checks?

Deep Checks was created by the team at Julian Capital with assistance from the deeptech community.

Mat Vogels
