Tucker Dordevic spent last year explaining aerospace and defence balance sheets to investors. The year before, he played professional lacrosse and won the Premier Lacrosse League's Rookie of the Year award. Neither job looks like preparation for building airspace sensors.
His co-founder's did. Isaac Duke was an engineer at Saronic, the Austin company building autonomous surface vessels. Duke's conviction was narrow enough to fit on a slide: you cannot protect what you cannot see. The two founded Austin Sensing Company in 2025, shipped a tripod-mounted RF detector this summer, and announced an $11M seed on 15 October. With an earlier pre-seed, total funding reaches $15M.
Bow Capital led the round. Bling Capital, Draper Associates, Mark VC, GTMfund and Ensemble VC joined.
The money buys the layer underneath every counter-drone system: the sensor that decides whether anything gets launched at all.
The Sensor Before the Interceptor
Counter-drone procurement has a sequencing problem. Effectors get the contract values and the conference demos. None of them can engage a target that no sensor has classified. A radar that reports “something” and an operator who cannot separate a delivery drone from a bird produce the same result: nothing happens, or the wrong thing does.
Austin Sensing's bet is that the bottleneck sits in that gap. Its stack starts with passive RF detection, adds acoustic classification and a compact radar, and fuses the three into one airspace picture. The company sells the picture. The missile stays someone else's product.
That framing travels well. A fire department can buy awareness without buying a weapons system. A defence buyer can route the same feed into an effector it already owns.

Company timeline from founder statements and the 15 October funding announcement.
The product names are literal. RF AS is a tripod-mounted detector rated at 28 square miles of coverage per unit. Duke says it picks up manned aircraft at 40,000 feet as well as FPV drones, and can indicate where the drone operator is standing. Acoustic AS classifies aircraft by sound across a full 360-degree field in under a second, including tethered drones that emit no radio signal. Radar AS tracks crewed and uncrewed aircraft out to 3 km. Tower AS bundles all three onto a single deployable mast.
| Layer | What it sees | Reach |
|---|---|---|
| RF AS | Radio emissions from drone and operator | 28 sq mi per unit |
| Acoustic AS | Propeller signature, including tethered aircraft | 360°, under 1 second to classify |
| Radar AS | Crewed and uncrewed aircraft | Up to 3 km |
| Tower AS | Fused view, networked across sites | Site scale |
Specifications as described by the company to Tectonic Defense, October 2026.
The interface decides whether the hardware matters. Operator AS is the company's own command-and-control layer, built to plug into Anduril's Lattice or Palantir's Maven rather than replace them. Duke's reason for building it in-house is practical: third-party integrations are rarely robust, and a sensing company that cannot turn its own knobs is exposed to someone else's API roadmap.
Fusion is where the claims get harder to check. Every vendor says it fuses sensors. The real test is whether a track holds when one modality fails — an RF-silent drone over a noisy stadium, a radar return lost in ground clutter. Austin Sensing has not published detection rates, false-alarm rates, or a head-to-head against a radar-only incumbent. The seed buys time to produce those numbers.
Passive First, Active Later
The order of the stack is not random. Passive RF detection is cheap, covert and long-ranged: a receiver listens for the control link and, in the best case, locates both the aircraft and the person flying it. It also fails against anything that stays quiet. Fibre-tethered drones, pre-programmed waypoints and autonomous terminal guidance all remove the radio link that RF depends on.
That gap explains the next two sensors. Radar supplies a return from objects that do not cooperate, at the cost of power, licensing and clutter. Acoustic detection catches the propellers at close range and works on tethered aircraft, but wind, traffic and distance degrade it quickly. Fusing three imperfect views is the only way to cover the failure modes of each.
The trade-off shows up in the specifications. RF covers 28 square miles per unit but sees only emitters. Radar reaches 3 km but needs line of sight and a clean return. Acoustic classification takes under a second but works over a short radius. A tower carrying all three is expensive per site; a network of cheap RF nodes is blind to silent drones. The customer's mission picks the mix.
That is also why the software layer carries the valuation. Hardware margins compress once three vendors sell comparable boxes. A fusion engine that improves with every deployment — more tracks, better classification, fewer false alarms — is the asset that compounds.
Sensor counts are the easy metric. The harder one is classification latency: how long between first detection and a track an operator can act on. Acoustic classification under one second is a start, but the clock that matters runs from detection to cueing an effector. Austin Sensing has not published that number, and neither have most of its competitors.
Why Public Safety Pays First
The go-to-market runs opposite to most defence startups. ASC sold first to police and fire departments, where procurement is faster and budgets renew annually. More than 40 agencies across four states now run the RF detector, according to the founders. A handful of defence customers are testing units.
Dordevic describes the sequence as deliberate. Civilian buyers came first because they fund the product and force a support organisation into existence. “We also wanted to develop almost a B2B SaaS company go-to-market,” he told Tectonic, “and we’re developing that muscle for public safety.”
That route has a cost. Public-safety deals are small, support-heavy and unforgiving on uptime. They reward onboarding and renewals, the unglamorous half of a hardware company. The 20,000-square-foot factory in Austin is the other half of the bet: enough production to serve both customer bases without waiting on a prime contractor's purchase order.
Procurement timelines add a second constraint. A police contract can close in weeks. A defence program of record can take years and may never arrive. Companies that bridge the two usually survive on the commercial side while the military side matures. Forty agencies are that bridge, and the factory is the capacity to walk across it.
The Detection Layer Is Crowded
ASC is not entering an empty market. Echodyne sells compact radar. Fortem and Hidden Level sell detection systems already inside defence programs. CHAOS Industries pairs sensing with interceptors. As we wrote in October, when MBDA added Fortem's interceptors, the plug is becoming the product; the integration layer now decides who wins the account.
Incumbents mostly sell one modality well. ASC pitches the opposite: an integrated stack from one vendor, with software that treats RF, sound and radar as three views of the same track. That is a harder engineering problem and a simpler procurement story. One contract, one integration, one accountable supplier.
Whether buyers want that trade is unresolved. An integrator with an existing radar may prefer best-of-breed sensors and its own fusion layer. A police department with no integration team may prefer the bundle. Both can be true in different segments, which makes the seed a test of segmentation as much as technology.
What $15M Actually Buys
Radar and acoustic units ship at the specifications quoted in testing
The 40-agency base converts into renewals instead of one-off pilots
Defence trials become a program of record before sensing budgets consolidate around two or three vendors
None of that is a technology moonshot. It is execution on manufacturing, support and integration — the part of defence tech that venture capital usually underfunds and incumbents usually win.
The cost-per-shot debate has dominated counter-drone coverage for two years, including the laser economics we examined with Aurelius Systems. Detection is the quieter line item, and it sets the ceiling on everything downstream. An airspace picture that misses the drone makes a cheap interceptor expensive and a good one irrelevant.
One number separates a sensing company from a demo. It is not the range on a spec sheet. It is the share of tracks an operator would act on twice.
