Scaling deep-tech and dual-use founders into market leaders
The deep-tech and dual-use landscape is one of the most exciting places to invest right now — and one of the least understood by generalist investors.
At Seed Round Capital, we’ve backed companies developing advanced carbon materials, radioisotopic persistent power systems for defense and space applications, ISS National Lab award-winning contactless magnetic gears, and autonomous maritime platforms operating with the U.S. Navy. We’ve co-invested with leading deep-tech and dual-use VCs — firms that have spent years building the playbooks for investing in frontier technology and at the defense-commercial intersection.
Here’s what we’ve learned about what separates the companies we invest in from the ones we don’t.
The founder has to be a capital-efficient engineer. Deep-tech founders often think in terms of what the technology can do. We think in terms of what it can do before the next round closes.
The technology has to solve an urgent, timely need. Whether it’s persistent power for remote sensors and small satellites where batteries fail, frictionless gears for environments where lubricants simply don’t work, or next-generation advanced carbon antennas — the best deep-tech companies we’ve seen are solving problems that existing solutions genuinely cannot solve.
The team has to be coachable and have a clear path to traction. Deep-tech founders are often brilliant technologists who are fundraising for the first time in a market that doesn’t reward the slow, linear thinking of traditional R&D.
If you’re a deep-tech or dual-use founder raising your pre-seed or seed round, we’d like to learn about what you’re building...

Most deep tech founders don’t fail on the science. They fail on the path to Series A: burning capital before technical validation, mistiming SBIR and grant cycles, or pitching generalist investors who can’t underwrite the risk. We help you avoid those mistakes. Read our founder blog.
IS YOUR DEEP TECH STARTUP INVESTOR-READY?
We've reviewed thousands of deep tech startups and invested in more than 80. The same 10 factors separate the companies that raise from the ones that stall: technical depth on the founding team, technology proven outside the lab, protected IP, validated customer demand, real commitments from buyers or partners, non-dilutive funding wins, a clear path to government and commercial revenue, known unit economics, and a raise tied to specific milestones.
