The war in Ukraine has made unmanned vehicles central to modern combat, and the cycle of measure and countermeasure now runs in months and weeks. No outsider can follow that pace, and no early-stage investor can predict which vehicle will win. An investor can, however, back what every winner will need. That idea leads to three questions an early stage investor should ask of defense startups: Where does it play? Is the demand real? Who will pay for it to scale?
The Market Rewards Discipline
Government demand is real but narrow. The Pentagon's Drone Dominance program, an 18-month, $1.1B effort, aims to buy hundreds of thousands of one-way attack drones by the end of 2027. Yet its first round split a $150M order among 11 companies, and its second drew 48 companies with about 78 designs.
Much of this has been financed by expensive equity capital. Defense and adjacent startups raised $35.6B in the first half of 2026, and early-stage companies reportedly raised at 17 to 50 times revenue. Anduril's CEO Brian Schimpf calls the market ‘in a bit of a bubble’ and warns that companies burning cash without production contracts will face down rounds.
Where Should an Early Stage Investor Play?
Remove a bottleneck. Back companies that remove a bottleneck rather than add one more platform. Training and simulation tools for autonomous vehicle operators are a case in point, because operator skill limits this type of warfare more than hardware does. Supply-chain software also checks that box since every manufacturer in the Pentagon's drone program must prove that motors and batteries come from outside China.
Invest in a layer, not a whole system. A stable layer, such as motors, batteries, magnets and sensors, sells no matter which manufacturer wins. A fast layer, such as jam-resistant communications, navigation without GPS, or swarm control, keeps pace with the front and sells for every vehicle. A seed-stage drone airframe, by contrast, competes as one more platform, and the next iteration of the war will make its design obsolete.
Require an advantage rivals cannot copy. A prime contractor or a better-funded rival must not be able to rebuild the product in a quarter. The advantage can be proprietary data, access to classified networks, a security authorization (ATO), or a design proven in combat, such as Ukrainian technology licensed or co-produced in the United States. Thin "defense AI" companies will fail this test.
Prefer dual use. A commercial market will carry the company when defense budgets swing. Navigation without GPS also serves agriculture and logistics; drone motors and batteries also serve industrial robots.
Is the Demand Real?
Require contracts with money and a buyer. Real traction means an awarded contract with funding behind it, a named buyer, and a path to production. A prototype contract (OTA) counts when a program office has committed to the follow-on and has named the buyer. A finalist slot, a zero-dollar CRADA or an SBIR Phase I shows interest, but it does not count as traction.
Require a funded path to a program of record. The best early-stage companies keep their burn low until a program funds them, so each equity round buys progress rather than survival. Ask the founder to name the program, the budget line and the champion who will carry the company there, and to show how long current cash lasts.
Value the company on appropriated money and price the round on contracts Congress has funded and program offices have awarded. The FY2027 budget request seeks $54.6B for the Defense Autonomous Warfare Group, up from about $225M in FY2026, but Congress has not yet appropriated it. But a budget request is only an option the company may win, not revenue it can count today.
Who Pays to Scale?
Capital-intensive hardware companies raise round after round before revenue is generated, and each round dilutes the investors who came in first. An angel's equity should therefore fund design, certification and early sales, and someone else should pay for the factory. Software companies meet this rule outright. Hardware companies meet it when one of two sources finances production.
Look for a contract that lenders will finance. US government receivables make strong collateral. Lenders finance purchase orders and receivables, and the Assignment of Claims Act lets a contractor assign government payments to a lender. Machine tools and production lines with resale value can also carry equipment loans.
Look for government capital. The Office of Strategic Capital lends to companies in critical supply chains, and Defense Production Act Title III awards fund new production capacity.
Back What Every Winner Needs
The developments in an actual conflict change faster than any outsider can follow. An angel trying to pick the autonomous vehicle that wins is akin to playing the lottery. Every autonomous vehicle, though, will need operators who can move it, components that pass the sourcing rules, software that survives jamming, and a factory that someone else but the angel paid for.
