The Startup Whose Drones Fly Blind, in the Dark, at -20F, Inside Your Freezer

A decade-old inventory problem meets a drone that navigates without GPS, light, or a single sticker on the wall.

Inside a Kroger cold storage facility, the freezer aisles sit at minus 20 degrees Fahrenheit, dark enough and cold enough that human workers rotate through in short shifts wearing insulated gear rated for arctic exposure. A small drone lifts off a charging dock, threads between racks stacked dozens of feet high, and reads barcodes frosted over with ice. No one is flying it. There is no Wi-Fi beacon guiding it, no reflective sticker marking its position, no light switched on for its benefit. It simply knows where it is, because the AI system onboard built a model of the space the first time it flew through and has been refining that model ever since. This is Corvus One, and it is quietly replacing one of the most dreaded jobs in American logistics: counting frozen inventory by hand.

From an MIT Dorm Room to Kroger's Freezers

Corvus Robotics traces back to 2017, when Mohammed Kabir, then a freshman in MIT's Department of Aeronautics and Astronautics, got a message from Jackie Wu, at the time a robotics graduate student at Northwestern University. Wu had come across Kabir's work on drone navigation in GPS-denied environments through an open-source drone project and floated the idea of turning it into a company. Kabir built the first Corvus drone in his MIT dorm room, working nights and weekends around his coursework. He was already a founding member of MIT Driverless and an early contributor to PX4, one of the most widely used open-source autopilot systems in the drone industry.

The founders initially tried retrofitting off-the-shelf drones with extra sensors and compute. It did not work. Off-the-shelf hardware could not give them the low-level control needed for what they were attempting, so they designed their own drone from the ground up. That decision became the foundation of what Corvus calls infrastructure-free autonomy: a system that requires no beacons, no localization markers, no reflective tape, and no lighting changes to fly and map a facility on its own.

The pitch was aimed at a problem that has barely changed in decades. Distribution centers typically count inventory twice a year, a process that ties up labor for days and still leaves managers flying blind between counts. "Typically, warehouses will do inventory twice a year, we change that to once a week or faster," Kabir has said of the shift Corvus enables. Wu, who studied economics at Northwestern before turning to robotics, has described his motivation in similar terms: better, faster data replacing guesswork, first for national economies and then, more practically, for the businesses that move physical goods around the country.

Engineering a Drone That Can Survive a Freezer

Warehouse automation has never been kind to sub-zero environments. Sensors fog. Batteries lose capacity in the cold. Condensation forms on lenses the moment a drone crosses from an ambient loading zone into a freezer. Corvus spent months re-architecting thermal management, sensing, flight stability, and onboard perception before it would put a drone into that environment commercially. CEO Jackie Wu has called it an engineering challenge most robotics platforms were never designed to handle.

The result, launched in February 2026, is Corvus One for Cold Chain, a variant purpose-built to operate continuously from minus 20 degrees Fahrenheit up to ambient temperature. It uses industrial-grade barcode scanners with adaptive focus and exposure control so it can still read a label that is frosted over, glare-washed, or partially damaged. Flight control is stabilized to compensate for the powerful airflow generated by freezer blowers and cycling door activity, and the whole system runs under a Robots-as-a-Service model that handles its own battery swaps and health monitoring so it can maintain uptime without an on-site operator.

None of this required Kroger, or any customer, to change how its freezer floor operates. The drones fly during active shifts, adapt to blower airflow and door traffic in real time, and sync their scans directly into the warehouse management system already in place. Kroger has deployed the system across both ambient and sub-freezing cold chain operations, using it to replace the manual cycle counts that once required staff to suit up and enter freezer aisles just to verify what was on the shelf. According to Corvus, the deployment has progressed through multiple phases, from initial validation into full operational use, delivering weekly inventory visibility in place of the periodic physical counts the industry has relied on for decades.

The Case for Urgency: Nobody Wants This Job

The timing is not incidental. Cold storage warehouses report annual labor turnover exceeding 35 percent, roughly double the rate seen in ambient warehousing, according to the International Association of Refrigerated Warehouses. Some operators report turnover spiking within the first two weeks of a new hire's tenure, as workers discover in practice what a sustained shift at minus 20 degrees actually feels like. Facilities typically pay a premium of two to four dollars an hour to attract workers willing to do the job at all, and even then many warehouses are drawing from the same shrinking labor pool as every other cold storage operator in the region.

That backdrop is exactly why a drone willing to fly into conditions no human wants to work in is more than a novelty. It converts a job nobody wants to keep staffing into a task nobody has to staff at all, while directly addressing the safety exposure, frostbite and hypothermia risk, and musculoskeletal strain that regulators and operators alike have flagged as inherent to sub-zero manual labor.

Proof at Scale: Southern Glazer's

If Kroger shows Corvus working in the hardest environment it built for, Southern Glazer's Wine & Spirits shows what happens when the standard system scales across an entire network. Over eighteen months, Southern Glazer's has deployed more than 40 Corvus One drones across nine distribution centers nationwide, with expansion still underway. The fleet has logged approximately 5,000 flights and surfaced more than 35,000 verified inventory discrepancies, according to the companies' joint announcement.

"Across our network, inventory accuracy directly impacts how effectively we serve our customers," said Karli Sage, Southern Glazer's Vice President of Supply Chain Management, Technology & Engineering, describing a shift from quarterly counts to biweekly turns across facilities. The company has tied the rollout to a 100 basis point improvement in cases per hour, framing the accuracy gains as a direct contributor to faster, more reliable order fulfillment rather than just a compliance exercise.

The Money Problem: A Well-Funded Rival

Corvus is not the only company chasing this niche, and it is not the best-funded one. The company has raised roughly $28 million across its seed and Series A rounds, led by S2G Ventures and Spero Ventures, with backers including Tesla's cofounder and Y Combinator. Its most direct competitor, Verity, has raised more than $76 million, giving it a significant capital cushion in a market where enterprise sales cycles and multi-site fleet deployments demand sustained investment over years, not quarters.

Corvus is betting that its moat is architectural rather than financial: infrastructure-free autonomy that lets a facility go live without retrofitting a single aisle, versus systems that lean more heavily on fixed markers or localization hardware. Whether that technical edge outlasts a rival with nearly three times the capital is the open question hanging over the company's next few years. Industry analysts have also flagged that Corvus's Robots-as-a-Service unit economics, including fleet maintenance costs, device lifespan, and customer renewal rates, remain largely undisclosed, and that its named enterprise customer list is still short relative to the ambitions of a national rollout strategy.

What Comes Next

Corvus has kept adding to the platform. In April 2026, the company introduced Corvus Trident, a device aimed at giving warehouses a continuous record of every pallet from the moment it arrives at a dock door to the moment it departs. The company's existing customer base beyond Kroger and Southern Glazer's includes MSI Surfaces, Dermalogica, and Staci Americas, spanning industries well outside grocery and beverage distribution.

The bigger bet is architectural rather than commercial: that cold-chain labor shortages and falling costs for drone autonomy are converging at the same moment, ahead of competitors with deeper pockets scaling into the same niche. Twice-yearly manual counts became standard in distribution centers because nothing else was practical in a GPS-denied freezer where humans could only work in short bursts. Corvus is wagering that the practical constraint has quietly disappeared, and that whoever proves it fastest, at the biggest scale, sets the standard the rest of the industry has to answer to.
