What startups are building affordable interceptors or non-kinetic defenses for drone swarms?

There’s a fairly active startup layer here, especially around the idea of “cost-per-engagement below the cost of the drone being defeated.” As of September 2026, I’d divide the field into two groups:

Low-cost kinetic interceptors

• Mara — Spike. Probably the clearest example of the “attritable interceptor swarm” concept. Its Spike system uses a Spotter sensor and magazines of roughly 250-g autonomous Seeker interceptors. Mara says the individual interceptors are intended to cost only a few hundred dollars, roughly matching the FPV drones they target; complete systems start around $30,000. The company raised $7M in August 2026 and says it is targeting ground deployment by the end of 2026.Tom's Hardware+2
• Neura Defense Systems — Raptor/Sentinel. A newer U.S. startup building an integrated sensor/C2/launcher/interceptor architecture. Its advertised economics are about $4,500 per intercept, with a tube-launched autonomous Raptor and a 12-cell Sentinel launcher. It specifically targets mass attacks and drones that defeat conventional RF-based defenses.Volantyx Aerospace+2
• ZenaTech/ZenaDrone — Interceptor P-1. Developing a single-use autonomous VTOL interceptor with a target price below $5,000, coupled to AI threat detection and swarm-command software. The important caveat is that this is still a development/prototype program rather than a mature deployed product.Zenatech+2
• Earendil Robotics — Aeglos. A YC Summer 2026 company focused specifically on small-unit counter-UAS. YC describes Aeglos as an autonomous interceptor that has already achieved operational intercepts, alongside spotting and engagement capabilities.Y Combinator+1
• Corvus Industries — ATLATL. Building a guided, AI-enabled kinetic interceptor intended for inexpensive, high-volume procurement, including operation without GPS or an RF datalink. Its current public material describes a roughly 5-km engagement range and a pre-seed round in 2026, so I'd classify it as early-stage.Corvus+1
• Perseus Defense — Harpe. Developing small autonomous missile interceptors for Group 1/2 drones, advertising under $10,000 per shot and a 2-km range. Like several companies above, the central proposition is replacing expensive conventional missiles with something that can be manufactured in large numbers.Perseus Defense+1
• Thalanor Dynamics — HALCON-100. Madrid-based startup developing small autonomous interceptor drones, including a non-destructive variant, with onboard perception and external radar/RF/acoustic cueing.Thalanor+1

Non-kinetic / “one-to-many” defenses

This is arguably the more interesting category for actual swarms, because a single effector potentially defeats multiple aircraft without requiring one missile per drone.

• AnGard Microwave. A Dutch deep-tech startup spun out of TNO/University of Twente developing high-power microwave (HPM) systems specifically for drone swarms, including fiber-optic and autonomous drones that conventional RF jamming can't affect. It describes the system as having an effectively expendable “magazine” consisting of electrical power rather than ammunition.AnGard Microwave+2
• WaveLock Systems. Developing HPM directed-energy systems intended for 360° counter-swarm coverage. The company claims millisecond-scale engagements and emphasizes the economics of using electricity rather than physical interceptors. It's considerably earlier-stage than the established HPM players.WaveLock Systems+1
• Black Owl. Developing a high-power-microwave counter-UAS system in Europe, explicitly designed around massed swarms. Its approach is to defeat multiple aircraft with an electromagnetic effect rather than expend ammunition on each target.Black Owl+1
• This is no longer a tiny startup, but it remains one of the most important venture-backed companies in this category. uses software-defined HPM to defeat multiple drones and is explicitly designed around the swarm problem. says its systems can produce wide-area effects while retaining precision targeting.

A slightly different non-kinetic approach

D-Fend Solutions is worth knowing about, although it isn't really a startup anymore: Motorola Solutions completed its $1.5B acquisition in August 2026. Its EnforceAir system uses RF cyber takeover rather than jamming, attempting to take control of rogue drones and bring them down safely. That is particularly relevant for airports, public venues and infrastructure where kinetic defeat isn't desirable.Motorola Solutions+1

The interesting economics

The companies are attacking the problem at three different economic levels:

One particularly notable development is Mara's attempt to push the interceptor all the way down to the few-hundred-dollar range. That's a materially different proposition from simply making a $50K–$100K missile cheaper.Tom's Hardware

Also worth watching is Mach Industries' Dart, which combines its own low-cost interceptors with FMCW radar and C2 in an integrated counter-swarm system.Mach Industries

If you're looking at this from an investment/industry-landscape perspective, I can also map these companies by estimated interceptor cost, maturity/TRL, funding, customers/contracts, swarm capability, and whether they have demonstrated actual intercepts.

Yes. The startup landscape is increasingly splitting into very-low-cost kinetic interceptors and non-kinetic/“soft-kill” systems designed to make swarm attacks economically difficult to sustain.

Low-cost kinetic interceptors

• mara.inc — Its Spike system uses small autonomous “Seeker” interceptors launched from a backpack/vehicle-mounted system. Mara says the individual interceptors are intended to cost roughly the same as the FPV drones they attack, with the system designed specifically for swarm-scale threats. It raised $7 million in August 2026.Tom's Hardware+1
• perseusdefense.com — Developing the Harpe portable interceptor, advertised at under $10,000 per shot, with an integrated launcher/tracking architecture for Group 1–2 drones.Perseus Defense
• T4 Robotics — Building AI-commanded interceptors around existing Ukrainian combat-proven drone platforms. The company describes a target interceptor cost of $2,000–$8,000, aimed at making one-for-one interception economically viable against FPVs and loitering munitions.T4 Robotics
• Mach Industries — Its Dart system combines internally developed FMCW radar, C2 and inexpensive interceptors specifically for Group 1–3 threats and coordinated swarms.Mach Industries
• ZenaTech / ZenaDrone — Developing the Interceptor P-1, a single-use autonomous VTOL interceptor with a targeted price of under $5,000, plus software intended to coordinate multiple interceptors.ZenaTech+1
• Neura Defense Systems — An emerging counter-swarm company building an integrated sensor/C2/launcher/interceptor architecture. It advertises approximately $4,500 per intercept and specifically targets RF-silent, fiber-optic and autonomous drones that defeat conventional RF jamming.Volantyx Aerospace+1
• KOMIKAZE.AI — Developing very-low-cost kinetic interceptors, with its KX-1 advertised at $1,000–$2,000 and the broader platform emphasizing inexpensive, mass-produced systems. Much of this appears to remain developmental rather than field-proven.Komikaze+1

Non-kinetic / low-kinetic approaches

This category is somewhat harder to define because many startups combine electronic warfare, sensing and kinetic effects.

• Parallax Defense — Claims a low-kinetic, non-fragmenting effector intended to provide extremely low cost per engagement and an effectively unlimited magazine. Its system is designed to detect and track RF-silent/autonomous drones rather than depending exclusively on RF detection or jamming.Parallax Defense
• Talyra Technologies — Taking a different approach: rather than physically defeating every drone, its software creates decentralized coordination among low-cost defensive interceptor drones, intended to let a group of inexpensive systems respond to a numerically superior swarm.Talyra Technologies
• DroneShield and Epirus are also important names in the non-kinetic counter-UAS market, although they're considerably more established than the startups above. Their approaches include electronic warfare and high-power microwave technologies rather than cheap expendable interceptors.

One particularly interesting trend

The economics are changing rapidly. Traditional air-defense missiles can cost hundreds of thousands to millions of dollars, while the new generation of counter-drone companies is explicitly targeting $1,000–$10,000-class interceptors. Reuters reported in September 2026 that European defense planners are increasingly pursuing inexpensive, mass-producible interceptors; it identified startups including Destinus, Cambridge Aerospace and Fire Point among companies working on this cost problem.Reuters

For true swarm defense, I'd distinguish three approaches:

The most notable technical issue is that RF jamming alone becomes much less useful against autonomous or fiber-optic drones, which is why several of the newer companies are combining passive sensing, AI tracking and autonomous interceptors rather than relying solely on electronic warfare.PR Newswire+1

If you're looking at this from an investment/industry-landscape perspective, I can also map these startups by estimated interceptor cost, maturity, funding, customers/contracts, and whether their technology is actually demonstrated versus still a concept.

If you mean startups specifically attacking the cost-per-drone problem, there’s a surprisingly active group. The most relevant companies fall into two buckets: very-low-cost kinetic interceptors and non-kinetic/soft-kill systems that can engage multiple drones without firing a missile at each one.

Low-cost kinetic interceptors

• Mara — Spike. San Francisco startup developing a backpack-portable autonomous interceptor. Mara says the ~250 g interceptor is intended to cost roughly the same as the inexpensive FPV drones it defeats; it raised $7M in August 2026.GlobeNewswire+1
• IMPACT Drones. YC-backed startup developing autonomous interceptors launched from sealed containers. Its concept is explicitly aimed at infrastructure sites and emphasizes an interceptor cheaper than the incoming drone, with a subscription/“air defense as a service” model.Y Combinator
• Herakles Defense. Developing a small autonomous drone-on-drone interceptor that defeats FPVs through collision rather than a warhead, with no dependence on GPS or RF links.HERAKLES
• Corvus Industries. Building an AI-guided, fire-and-forget kinetic interceptor designed for volume deployment and operation without GPS or an RF datalink.Corvus
• Rattlesnake. Polish startup developing a rapid-fire autonomous counter-drone system; it advertises an intercept cost below €10 and has reported autonomous interception testing in 2026.Rattlesnake
• Fortem Technologies. More mature than the others, but particularly relevant: its DroneHunter interceptors physically capture hostile drones rather than destroying them with explosives. In February 2026, Fortem demonstrated five autonomous interceptors simultaneously defeating five drones.Fortem Technologies

Non-kinetic / swarm-oriented

• Epirus — Leonidas. Probably the clearest startup example of the non-kinetic swarm-defense approach. Leonidas uses software-defined, solid-state high-power microwaves to affect multiple drones/electronics, rather than expending one missile per target. Epirus explicitly markets it for counter-swarm applications and emphasizes low marginal cost per engagement.Epirus+1
• VANEA Defence — ATOMZA. European startup focused on counter-UAS for airports, critical infrastructure and other civilian sites. Its August 2026 announcement describes ATOMZA as a production-ready system intended to let private operators deploy active counter-drone defenses without sovereign enforcement powers.VANEA Defence
• Neura Defense Systems. Emerged from stealth in June 2026 with an autonomous counter-swarm platform that fuses different sensors and is specifically aimed at threats such as fiber-optic and autonomous drones that defeat conventional RF detection/jamming.PR Newswire

A couple of larger startups worth watching

• Anduril — Anvil. No longer an early-stage startup, but its Anvil family is an important benchmark: autonomous, ground-launched kinetic interceptors integrated with Lattice.Anduril+1
• Earendil Robotics. YC Summer 2026 company working on small-unit counter-UAS using sensors, autonomous interceptors and integrated systems, with an emphasis on contested electromagnetic environments.Y Combinator

The interesting dividing line is economics: a conventional $1M+ interceptor is problematic against a swarm of $500–$5,000 drones. The newer startups are therefore experimenting with $100s–$10,000s autonomous interceptors, collision-based defeat, reusable capture, or area-effect electromagnetic weapons. That is also consistent with the broader 2026 defense-market push toward mass-producible, cheaper interceptors.Reuters

If you're looking at this from a startup/investment/competitive-landscape perspective, I can also map these companies by estimated interceptor cost × swarm capacity × maturity × funding × military contracts, which gives a much clearer picture of who is actually differentiated.

The defense technology landscape has shifted heavily toward low-cost, high-volume counter-UAS (C-UAS) solutions to combat drone swarms, moving away from multi-million dollar traditional missiles.newmarketpitch.com+1

Several key startups are building affordable kinetic interceptors and non-kinetic defense systems tailored to neutralize swarms:

Affordable & Kinetic Interceptor Startups

• Mara (San Francisco, USA) – Developing the Spike portable counter-drone system, which features tiny, ultra-lightweight autonomous interceptors called Seekers . Designed to counter fast FPV quadcopters in a 1-to-1 cost match, the backpack-portable system aims for a dramatic cost advantage over legacy interceptors.defensedaily.com+2
• Neros (Torrance, USA) – Building an affordable interceptor drone named Bandit , with basic models targeted at around $5,000 per unit to address the cost asymmetry of modern drone conflicts.nytimes.com
• Fortem Technologies (Pleasant Grove, USA) – A pure-play C-UAS specialist known for its DroneHunter —a reusable, radar-guided, net-capturing interceptor drone backed by its SkyDome AI software. It safely captures rogue drones without kinetic explosions, making it ideal for swarms in populated or sensitive areas.newmarketpitch.com+1

Non-Kinetic & Directed-Energy Defenses

• Epirus (Torrance, USA) – A leader in high-power microwave (HPM) technology. Epirus builds Leonidas , a software-defined directed energy system that can neutralize swarms of drones simultaneously with electromagnetic pulses rather than physical projectiles.
• Allen Control Systems (USA) – Specializing in ultra-fast, computer vision-enabled kinetic gun systems (such as Bullfrog ) that use AI-driven turret automation to track and blast small, fast-moving drones out of the air at a fraction of the cost of missile defense.
• Powerus (USA/UAE) – Manufacturing low-cost interceptor solutions and scaling production regionally to meet surging demands for counter-swarm technology.nytimes.com

If you'd like to dive deeper, let me know if you want to focus on:

• Kinetic vs. non-kinetic trade-offs
• Readiness and deployment timelines for active conflicts
• AI and autonomy capabilities used for swarm targeting

If you mean startups specifically attacking the cost-exchange problem posed by mass drone attacks, there’s a surprisingly active field. I’d divide them into cheap kinetic interceptors, non-kinetic/direct-energy systems, and novel capture/disable approaches.

Low-cost interceptors

• Terra Drone — Probably one of the most interesting established startups in this category. It is developing relatively inexpensive autonomous interceptor drones, using AI, radar and cameras rather than expensive missile architectures. Its recent move into defense is explicitly motivated by the economics of Ukraine-style drone warfare.The Wall Street Journal
• ZenaTech / ZenaDrone — Developing the Interceptor P-1, an expendable autonomous VTOL interceptor with a stated target price below $5,000. Its planned C-UAS architecture also incorporates software for coordinating multiple interceptors.ZenaTech+1
• Mara — Its Spike system uses distributed sensors plus small, expendable interceptors. The company says the 250-gram interceptor is intended for the small FPV-drone threat and that the architecture is designed to engage multiple directions simultaneously. Mara announced a $7 million funding round in August 2026.GlobeNewswire
• Perseus Defense — Developing the Harpe micro-interceptor, advertised at under $10,000 per shot, with a 2-km range and an emphasis on mass production and portability.Perseus Defense
• Martel Defense — Its Bolt/Archer architecture is particularly interesting economically: a carrier drone brings small interceptors close to the target, allowing the actual interceptor to remain inexpensive. Martel advertises under $6,000 per shot.Martel Defense LLC
• Neura Defense Systems — A newer entrant building an integrated sensor/launcher/interceptor system around expendable Raptor interceptors. It claims roughly $4,500 per intercept and sub-two-second sensor-to-engagement times.Volantyx Aerospace
• SwarmFisher — An unusual non-destructive approach: autonomous interceptor drones physically capture hostile drones with nets rather than destroying them. That could be attractive around airports, infrastructure and other locations where falling debris is unacceptable.SwarmFisher

Non-kinetic / directed-energy

• Black Owl — One of the more directly relevant startups for swarm defense. Its DEDS system uses high-power microwaves, where a single emission can affect multiple drones rather than requiring one interceptor per aircraft. The company explicitly describes the system as being designed for massed swarms and emphasizes electricity rather than ammunition as the magazine.Black Owl
• Epirus — Its Leonidas high-power microwave technology is one of the best-known examples of the "one-to-many" approach. HPM is particularly interesting against swarms because the marginal cost of engaging additional drones can be dramatically lower than firing individual missiles.Drones & Defense
• Aurelius Systems — Developing Archimedes, an autonomous counter-UAS laser combining sensors, AI and high-power directed energy. The concept is to deploy multiple relatively compact nodes as a persistent defense grid.Aurelius Systems
• ADAMA Technologies — German startup developing high-power laser C-UAS systems. It advertises engagement costs below , with the practical magazine limited primarily by available electrical power rather than ammunition.

Particularly interesting emerging approaches

• Parallax Defense — Claims a low-kinetic, non-fragmenting effector intended to provide extremely cheap engagements while integrating detection, tracking and defeat into one autonomous system. It specifically pitches the system against RF-silent, fiber-optic and autonomous drones that defeat conventional jamming.Parallax Defense
• Cydra Defense — Developing small autonomous interceptor aircraft using acoustic and optical sensing, with a stated goal of making the interceptor cheaper than the drone being defeated. Its prototype is aimed at quadcopter swarms and other small UAS.Cydra Defense
• Talyra Technologies — This is more of a software layer than an effector: decentralized swarm-control technology intended to let groups of inexpensive defensive drones cooperate in contested environments where GPS and communications are degraded.Talyra Technologies

My shortlist

If I were mapping the startup landscape specifically around "how do you stop 50–500 cheap drones without spending $1M per kill?", I'd pay closest attention to:

The key distinction is that cheap interceptors solve the "cost per target" problem, whereas HPM/laser systems potentially solve the "magazine depth" problem. For a genuinely large swarm, I think the latter is strategically more interesting—provided power, weather, range and beam-control constraints can be solved.

One caveat: many of these are very young companies and their advertised prices/performance are company claims, not necessarily independently demonstrated operational economics. The market is moving extremely quickly in 2026.

If you're interested, I can also make a competitive landscape of ~20 startups, with funding, country, interceptor price, range, swarm capacity, TRL/prototype status, and known defense contracts.

The economics of modern drone warfare heavily favor the attacker—firing a multi-million-dollar missile at a $500 to $1,000 FPV or loitering munition is unsustainable. To reverse this math, a new wave of defense technology companies and startups are engineering low-cost kinetic interceptors, reusable systems, and specialized tactical countermeasures.youtube.com+1

1. Powerus

• The Tech: Creator of the Guardian interceptor family (including Guardian 1 and Guardian 2).youtube.com+1
• How it works: Inspired by proven Ukrainian counter-UAS combat designs, the Guardian is a high-speed, precision-guided interceptor capable of hitting speeds over 200 mph to physically ram or destroy one-way attack drones and low-tier threats. The components snap together like Lego bricks utilizing off-the-shelf microchips and GPS modules, bringing the cost down to roughly $5,000 per unit.nytimes.com+3
• Status: Blue UAS Approved, with scaled manufacturing operations expanding internationally (including modular production facilities in the UAE).power.us+2

2. Tytan Technologies / European Defense Innovators

• The Tech: Tytan anti-aircraft interceptor drone.youtube.com+1
• How it works: Designed to counter mass-produced swarm tactics that overwhelm traditional batteries, Tytan acts as a fast, highly scalable kinetic shield. Costing under $5,000 per unit, it fills the economic gap between ineffective electronic jamming and overly expensive surface-to-air missiles.youtube.com+1
• Status: Backed by manufacturing contracts aimed at scaling thousands of units annually for European and allied defense frameworks, drawing extensive operational feedback from trials in Ukraine.youtube.com+1

3. BagNet Interceptor Projects

• The Tech: BagNet Interceptor drone system.
• How it works: Developed collaboratively via European defense initiatives, BagNet uses portable tube launchers capable of firing salvos of up to 10 interceptor drones at a time. Designed to ram and disable hostile drones at speeds up to 150 km/h, units cost under $10,000 and target dense urban perimeters or fast-moving tactical convoys.
• Status: Active production and scaling trials, operating as a low-end multi-launch swarm layer.youtube.com+1

4. Defense Primes Adapting Non-Kinetic/Reusable Models (e.g., RTX / Raytheon)

• The Tech: Coyote Block 3 Non-Kinetic
• How it works: While Raytheon is a defense giant rather than a traditional startup, the Coyote Block 3 represents the prime industry shift toward non-kinetic solutions. It carries a reusable/recoverable non-kinetic payload that can loiter in an area, search out incoming swarms, disable them without traditional explosive warheads, and potentially return if unexpended—drastically lowering the cost-per-engagement curve.youtube.com+1

Would you like to explore non-kinetic electronic warfare and high-power microwave (HPM) startups handling swarms, or dive deeper into AI-piloted interceptor drone software?

Yes. The interesting market is splitting into cheap physical interceptors and non-kinetic “magazine-depth” systems that can engage many drones without firing a conventional missile for every target.

Most relevant startups

• Mara — Probably the clearest “cost-per-interceptor” bet right now. Its Spike system uses a launcher carrying up to 48 small autonomous Seeker interceptors. The company says each interceptor is intended to cost roughly the same as the attack drone—potentially hundreds of dollars—and has demonstrated the concept in Ukraine.Tom's Hardware
• Origin Robotics — New Zealand startup developing BLAZE, an autonomous physical interceptor aimed specifically at inexpensive drones. It is one of the more interesting approaches for defeating autonomous or fiber-optic drones where RF jamming isn't reliable.New Market Pitch+1
• Fortem Technologies — More mature than a typical startup, but highly relevant. Its DroneHunter 5.0 is an autonomous net-capturing interceptor, while SkyDome coordinates multiple interceptors. Fortem demonstrated five simultaneous autonomous intercepts against a five-drone attack in 2026.Fortem Technologies+1
• TYTAN Technologies — Developing METIS, a low-cost autonomous interceptor. Its focus is essentially the same economic problem: don't defend a $100k+ target with a million-dollar missile.New Market Pitch
• Frankenburg Technologies — Building compact, relatively inexpensive guided anti-drone missiles. This is closer to a conventional hard-kill interceptor than Mara/Origin's tiny-drone approach, but its business model is explicitly high-volume/low-cost.New Market Pitch
• Terra Drone — Particularly interesting because it is moving from commercial drones into defense. Its Terra B1 is a 3D-printed rocket-powered interceptor designed for mass production against Shahed-type and other one-way attack drones; Japan has approved mass procurement.The Wall Street Journal+1

Non-kinetic / counter-swarm

• Epirus — Probably the standout startup in non-kinetic counter-swarm. Its Leonidas high-power microwave system uses directed electromagnetic energy to disable drone electronics. Unlike conventional jammers, it is designed to defeat swarms, autonomous drones and even fiber-optic-guided systems. Epirus and Digital Force Technologies are integrating Leonidas with sensor/C2 software into a complete non-kinetic kill chain.Epirus+1
• Hidden Level — More of a sensing/enabling layer than a defeat system: its passive radar technology provides long-range drone detection and tracking that can feed inexpensive interceptors or EW systems.Drone Intelligence

My take on the most interesting economics

If the requirement is “defeat a swarm without getting trapped in a $1M-per-shot economics problem,” I'd watch these particularly closely:

The key technical distinction is that “non-kinetic” doesn't necessarily mean “cheap.” Conventional RF jamming can be inexpensive per engagement, but it struggles against autonomous, frequency-agile and fiber-optic-controlled drones. HPM is more interesting for swarms because one system can potentially affect multiple electronics-dependent targets without maintaining a one-to-one interceptor-to-drone ratio. Epirus explicitly positions Leonidas around that counter-swarm advantage.Epirus

And on the interceptor side, Mara's approach is unusually aggressive on the cost curve: if a defensive interceptor really can be produced for roughly the same cost as the incoming FPV drone, it changes the swarm-defense equation substantially.Tom's Hardware

If you're looking at this from an investment/competitive-intelligence perspective, I'd rank Mara, Epirus, Origin Robotics, Fortem and TYTAN as the five most interesting companies to investigate, with very different theses behind each.

Yes. If you mean startups/younger defense-tech companies trying to fix the “$500 drone vs. $100k–$5M interceptor” economics, there’s a pretty interesting group emerging. I’d divide them into cheap physical interceptors and non-kinetic/electronic defenses.

Low-cost interceptors

• Mara — probably one of the most interesting new entrants. Its Spike system uses tiny autonomous interceptors carried in a portable launcher/sensor package. Mara says the ~250 g interceptors are intended to cost roughly the same as the FPV drones they defeat, with complete systems starting around $30,000. It raised $7M in August 2026.Tom's Hardware+1
• ZenaTech / ZenaDrone — developing the Interceptor P-1, a single-use autonomous VTOL interceptor with a targeted price below $5,000. It began flight testing in July 2026 and is intended to be coordinated by AI software against drone swarms.ZenaTech+1
• Mach Industries — its Dart is an integrated counter-UAS system combining FMCW radar, C2 and low-cost interceptors, explicitly designed for Group 1–3 threats and swarm attacks.Mach Industries
• Neura Defense Systems — an emerging startup building an integrated sensor/launcher/interceptor architecture. It advertises roughly $4,500 per intercept, a sub-two-second sensor-to-effect timeline, and expendable autonomous “Raptor” interceptors. This one is much earlier-stage than the established names.Volantyx Aerospace
• Powerus — developing the Guardian-1, a relatively inexpensive high-speed interceptor intended for larger one-way attack drones such as Shahed-class systems.Nasdaq
• X-Bow Systems — somewhat higher up the cost spectrum: its Buckler is aimed at Group 3 UAS and is designed to come in below $100,000, rather than competing with $300 FPVs directly.Defense News

Non-kinetic / electronic approaches

• Epirus — arguably the standout startup here. Its Leonidas high-power microwave system uses electromagnetic energy rather than projectiles and is explicitly designed for one-to-many counter-swarm defense. Epirus says its approach is intended to dramatically reduce the cost-per-engagement and has been selected for the U.S. Army's IFPC-HPM program.Epirus+1
• Sentrycs — takes a different approach: passive RF detection plus protocol manipulation/cyber-over-RF to identify and potentially take control of drones. Its systems can be deployed in fixed, vehicle or portable configurations.Sentrycs+1
• D-Fend Solutions — another major RF-cyber approach, using EnforceAir to take control of rogue drones and direct them to safe landing locations rather than destroying them. It's worth noting that D-Fend is : completed its $1.5B acquisition in August 2026.

The ones I'd watch most closely

If the question is “who is genuinely attacking the swarm cost problem?”, my shortlist would be:

One particularly interesting trend is hybrid defense: rather than finding one magical anti-swarm weapon, companies are combining cheap sensors + software/C2 + electronic effects + extremely cheap interceptors. That's much closer to solving the underlying economics than simply making a smaller missile.

For comparison, even established players are moving this way: RTX demonstrated a non-kinetic Coyote variant against multiple drone swarms in 2026, while Anduril's portfolio includes both the kinetic Anvil interceptor and reusable Roadrunner.RTX+1

If you're looking at this from a venture-investing/startup landscape perspective, I can also rank ~15 companies by estimated interceptor cost, funding, technical differentiation, government traction, and likelihood of becoming a major defense contractor.
