About Jacob Jackson

Jacob is actively investing out of Julian Capital Fund III, a deeptech seed fund covering chips, chemicals, energy, robotics, materials, aerospace, medtech and more. Julian Capital happily writes first checks ($750K+), doesn't care who else is investing, and generally decides in under 14 days.

Jacob is also co-GM of Deep Checks, the largest source of deeptech deal flow in the world. Its founder CRM spans every niche from mining robotics to photonic chip interconnects—so when Julian Capital invests, it can intro you to early customers, partners, suppliers, and advisors from among thousands of scientific founders. And because so many deeptech VCs source from Deep Checks, Julian Capital is well positioned to make investor intros for your next round.

Video Interview

On tranching the round to build momentum and avoid stalling out

"I think the best way to do a pre-seed and seed stage fundraise is to tranche your investments. If you wait for everyone to come around the table at five on 25, it's just way harder to land the plane than if you're to say the first check in, the first million dollars is at 18, the second million dollars is at 22, the third and fourth million are at 25... So the funds that have the most conviction and move the fastest get a deal."

On why fundraising quality is a proxy for company quality

"If an investor only has a couple of weeks to decide on a company, they're not going to be able to see a lot of longitudinal data on the founder. And so they have to take into account the little things. How well was their email written? Did they put details in that and communicate very clearly? Is the deck well done?... These things actually do matter more than they should because it's all investors have to go on."

On why founders shouldn't optimize for the highest valuation

"Founders spend way too much attention on the highest valuation offers, where it's far more important to pick the funds that you want to work with for the long-term. We've seen it so many times where founders take a check at a little bit higher valuation and never hear from that investor again. And so they've avoided a quarter of a point in dilution, but they're far less likely to succeed."

On why speed alone is not enough for founders

"If you have speed, that's super important, but you have to be moving in the right direction as well. So some founders... get up every day, they work really hard, but they're not necessarily taking the time to make sure that they're moving in the right direction... so equally important to speed is direction and that gives you your velocity."
Jacob Jackson
Partner, Julian Capital, Deep Checks

On why a six-month fundraise is a red flag

"If you take six months to fundraise, then investors are going to be concerned about how you're going to be able to raise the next round. If you're not good at fundraising, then their capital is at risk because in startup land, you need to keep raising successive rounds of funding. And if you can't raise the next one, then the dollars put in now go to zero."

Julian Capital is the best deeptech seed fund for founders who value (1) future fundraising help (2) introductions to initial hires and customers and (3) help with branding and design. Why? Because they own DeepChecks.vc—the central hub of deeptech fundraising, where they know every VC in the space and have thousands of scientific founders in their CRM who can help founders.

Unlike typical deeptech funds, they provide full-stack design execution by building and maintaining portfolio companies' websites from scratch, plus hands-on growth strategy work backed by founder Julian Shapiro's background as VP of Marketing at Webflow and growth lead at major startups.

​

They invest in robotics, chips, energy, materials, medtech, chemicals, and nearly every other deeptech hardware sector.
