Investment Thesis
DYNE Ventures proudly backs early-stage founders developing critical dual-use technologies for national security and defense — with a focus on advancing capabilities in the maritime domain.
Maritime Expertise & Focus Areas
DYNE Ventures was an early market entrant when it comes to early-stage maritime defense technology investing. We noticed there was a clear gap in attention, and funding, within the maritime defense ecosystem and we went out to build the relationships with government, operators and founders to understand the pulse of this underserved domain. With the opportunity to build at the foundation of this market still in front of us, we are at the right time, in the right place, with the right product.
We invest across four technologies that are redefining the economics of the future:
Sensing Technology
Data Collection: Exponentially more parameters will be captured at higher resolution.
Communications
Data Transmission: High bandwidth, global, persistent coverage ensures observability and command & control.
Robotics (Autonomy)
Data Action: Awareness, connectivity, and intelligence allow (semi) autonomous systems to extend human capabilities.
Edge Compute
Data Processing: Low energy, edge compute allows AI/ML models to run everywhere. Intelligence in every component.
We're drawn to the maritime domain given its underlying infrastructure and global importance: ports, shipping lanes, undersea cables — the physical backbone already exists and carries ~90% of global trade. No country in the history of the world has been deemed a "Superpower" without a powerful and technologically advanced Navy.
That power is no longer defined by hull count alone. As the defense landscape shifts toward attritable, distributed systems, naval strength increasingly means the ability to sense, source, and respond to threats across the vast, contested expanse of the world's oceans — not just project force from a handful of capital ships. Understanding that shift is what drove us to chase founders solving hard problems with real urgency.
The ones building for the operator, not the spec sheet.
Maritime Domain Challenges
A few structural challenges within the maritime domain — and they're not going away anytime soon:
Physics is unforgiving — water is a harder operating environment than the vacuum of space; fluid dynamics, drag, and buoyancy add engineering complexity that air and space don't
Harsh environment — corrosion, biofouling, pressure, degraded RF/acoustic comms
Concentrated, slow-moving customer base — Navy, allied navies via FMS, a handful of primes; procurement runs on political/bureaucratic will, not always merit
Commercial "dual-use" isn't a fast lane — shipping, offshore energy, aquaculture are thin-margin, conservative, slow adopters
Manufacturing bottleneck — atrophied US shipyard capacity, Jones Act dynamics, workforce shortage; great designs can stall behind production, not product
Talent scarcity — small overlap between naval architecture/ocean engineering expertise and startup-speed operators; deep talent skews prime- or Navy-trained
What Has Worked in the Portfolio
As referenced above, building for the operator, not the spec sheet
Building for government need, not government nice-to-haves
Software integrators versus OS reinventors
Company Highlights
Aalyria Technologies: Building the software and hardware backbone for communications that stay connected while everything is moving — satellites, aircraft, ships, and ground stations, across space, air, land, and sea.
Vatn Systems: Building low-cost, modular, swarm-capable AUVs engineered for the most demanding undersea environments.
Geographic Focus
Global investors focused on AUKUS and allied-nation innovation.
Long-Term Vision
The conflict in Hormuz showed the world how important the maritime domain really is — and that isn't reversing over the next decade. GPS-denial, dark fleets, and contested chokepoints from the Red Sea to the Taiwan Strait to the Baltics aren't a 2026 anomaly; they're the new operating environment. The infrastructure gap behind it — a generation of undermodernized ports, cables, and sensing — doesn't fix itself, it compounds, and we expect the winners to look less like shipbuilders and more like the Anduril’s, Palantir’s, and Vatn’s of the maritime domain.
Within 5–10 years, GPS-degraded autonomy and human-out-of-the-loop response won't be pitch-deck differentiators — they'll be the baseline anyone selling into this space must clear. Public and institutional attention is finally catching up to what the water has quietly carried all along — 90% of global trade, the world's energy, the cables the internet runs on — bringing capital and tailwinds DYNE didn't have five years ago. But the thesis doesn't depend on that attention holding; the founders treating the ocean as a hard engineering problem, not a hypothetical war zone, are the ones who'll own the category.
Exit Expectations
Given our principals' capital markets backgrounds, we underwrite all our investments for venture-scale outcomes — whether through acquisition or IPOs for our top performers. Our portfolio CEOs build with the same lens: toward acquisition or platform status from day one, not growth for its own sake.
DYNE Ventures Strategy
Stage & Check Size
DYNE Ventures’ Maritime Fund II is a Seed & Series A stage fund. We write initial checks ranging from $500K to $5M and reserve significant follow-on capital for top performers. With a holding period ranging anywhere from 5-10 years, we target ~5-6 investments per year. DYNE has the ability to lead investment rounds or participate alongside top-tier investors as part of a syndicate.
Supporting the Portfolio
DYNE operates alongside our founders as a hands-on partner — across business development, fundraising, and strategic planning. We don't invest in directly competitive technologies, and we put proper guardrails in place when founders are building in adjacent areas.
Track Record
DYNE's principals have collectively executed over 70 early-stage transactions.
Fund I has performed strongly: our founders are winning meaningful government contracts, outpacing competitors, and scaling revenue to lead in their maritime categories.
Decision Process
Initial Meeting
Diligence Kick-off (Product, Team, Market)
Advisor & Defense Advisory Committee Introduction & Feedback
Investment Memo Generation
Investment Committee Discussion & Decision
Term Sheet (If Applicable)
General Partners lead all decision-making for DYNE Ventures, taking into consideration our network’s input.
Typical Timeline: 3-4 Weeks
Support & Involvement
DYNE stays as hands-on as each portfolio company needs, calibrated through a regular cadence with our CEOs. We back people first — which means mutual respect and a shared vision for the business must be there from the start.
Post-Investment Support Consists of:
● Regular Check-Ins (some cases monthly, most cases DYNE is involved in ongoing discussions, with daily-to-weekly cadences)
● Network Enhancement: Customer & Strategic Partner Introductions
● Hiring Support
● Capital Markets Guidance
Boards
Selective board participation.
When Things Go Wrong
DYNE's posture doesn't change in good times or bad — we are hands-on, pragmatic, and focused on the best outcomes for our founders and our limited partners.
What We Wish Founders Asked
How do I find my MVP within the government — that initial relationship that says, "we need to be paying attention to these guys?”
How do I differentiate myself from incumbents to those who control procurement dollars, versus assuming a prime can do this for the government?
Who are the best investors to approach given our strategy — Silicon Valley generalists, or niche domain experts?
