The math of modern air defense has a problem. A Patriot missile costs millions. The drone it might be aimed at can cost less than a thousand euros. For Aleksander Djurka, a former data engineering lead at Stellantis, that imbalance looked less like a military challenge and more like a unit economics puzzle. His solution, now housed in a small Berlin workshop, is a drone designed to be cheaper than the threat it’s meant to destroy.
That product is the core of Axair Systems, a defense hardware startup founded in 2025. The company is building what it calls "AI interceptors",small, autonomous drones that use onboard computer vision to detect, track, and physically neutralize other drones. The key specification, repeated by its early investor F4 Fund, is a target unit cost of around €800 [F4 Fund, 2024]. The bet is that by making the interceptor itself attritable, or expendable, you flip the economic calculus of defending a perimeter against swarms of cheap, commercially available quadcopters.
A wedge built on cost and autonomy
The product wedge is straightforward. Traditional counter-drone systems often rely on expensive radar, jamming equipment, or missile-based hard-kill systems. These are effective but financially unsustainable against low-cost threats. Axair's approach is to build a simpler, single-purpose interceptor that is autonomous from detection to impact. According to the company's materials, the interceptor uses computer vision for guidance, eliminating the need for continuous human control or complex off-board sensor networks [Axair Systems, Unknown]. This aims to address two pain points simultaneously: the sticker shock of existing solutions and the operational burden of manning them.
The team behind the hardware
Founding a defense hardware company from a background in automotive data infrastructure is an unusual path, but Djurka's co-founder, Antoine Volard, and a third managing director, Markus Geese, round out the early leadership [northdata.com, 2026]. Djurka's prior roles at Stellantis, Vestiaire Collective, and Lazada/Alibaba point to a career built on scaling complex data systems, a skill set that may translate to the software and autonomy stack critical to the interceptor's function [startup.stream, 2024]. The team remains small, with LinkedIn listing the company at 2-10 employees [LinkedIn, 2024]. Their early backing comes from the F4 Fund, a European early-stage fund focused on defense technology, though the exact size of the investment remains undisclosed [F4 Fund, 2024].
Where the wheels could come off
Building a physical product that must reliably perform a complex, kinetic task in contested environments is a different class of problem from shipping software. The risks for Axair are substantial and multifaceted.
- Regulatory and certification hurdles. Selling to defense customers, especially in Europe, involves navigating stringent certification processes for both hardware and software. A prototype is one thing; a fielded system approved for military use is another.
- Technical performance under pressure. The promise of "onboard AI" for terminal guidance must work in all weather, against electronic countermeasures, and at the speeds required for interception. Failure here isn't a bug; it's a mission failure.
- Manufacturing and supply chain. Hitting the €800 price point at scale requires a supply chain and manufacturing process far beyond a Berlin workshop. The leap from prototype to production at volume, with the requisite quality control, is a capital-intensive endeavor.
- Competitive landscape. Axair is not alone. The company lists established German defense contractors like Hensoldt, ESG, and MBDA Deutschland as competitors, alongside other startups like TYTAN Technologies, which recently won a major German contract for interceptor drones [defence-industry.eu, 2026]. These incumbents have deep customer relationships and manufacturing muscle.
The rebuttal from Axair's corner would likely hinge on agility and software-centric design. A small team can iterate faster on autonomy algorithms than a large contractor, and a clean-sheet design built around attritability could avoid the cost structures of legacy systems. Their success depends on proving that this agility translates to a product reliable enough for a defense procurement officer to bet on.
The next twelve months
The immediate roadmap is about moving from concept to credible prototype. Key milestones to watch will be any announced partnerships with defense entities for testing, a clearer disclosure of funding to support hardware development, and public demonstrations of the interception capability. For a company at this stage, the next round of funding will be telling,it will signal whether specialist hardware investors believe the unit economics can scale from a datasheet to a production line.
On paper, the energy balance is compelling. If a €800 interceptor can reliably eliminate a threat worth several times its cost, the system pays for itself in a single engagement. Scale that across a fleet, and the defensive cost curve bends in your favor. The company Axair must ultimately outsell isn't just the startup next door; it's the entrenched defense prime offering a gold-plated solution to a problem that now demands something disposable. For militaries staring down the barrel of drone swarms, that disposable math is starting to look like the only kind that counts.
