The numbers are stark. In 2023, landmines and unexploded ordnance killed or maimed 5,757 people, a 22% increase from the year before. Thirty-seven percent of those casualties were children [lagertha.ie, retrieved 2024]. The problem is vast, spanning more than 60 countries, and the traditional tools for finding these hidden killers are slow, expensive, and perilous. Manual demining clears just 20 to 50 square meters per person per day [lagertha.ie, retrieved 2024]. Ground-penetrating radar systems, the current technological standard, can cost between €40,000 and €60,000 [lagertha.ie, retrieved 2024].
Lagertha, a pre-seed startup founded in Ireland in 2023, is betting that a drone-mounted sensor and an AI platform can change the economics of this grim business. Its proposition is simple: turn any commercial drone into a humanitarian detection platform. The goal is to provide evidence-grade mapping for clearance organizations at a price point it claims is three to five times cheaper than existing GPR systems [lagertha.ie, retrieved 2024].
The Hardware Wedge
The company’s initial wedge is a sensor payload designed to be attached to off-the-shelf commercial drones. This hardware-plus-software approach sidesteps the need to build an entire aircraft from scratch, focusing capital on the detection system itself. The AI software processes sensor data to identify potential threats and generates maps aligned with International Mine Action Standards (IMAS), the audit trail required by major humanitarian funders [lagertha.ie, retrieved 2024].
The unit economics are the core of the pitch. By targeting a system cost significantly below €40,000, Lagertha aims to move the technology from a specialist tool to a scalable asset for NGOs and national demining programs. The focus, according to a founder presentation, is on farmland in conflict-affected regions like Ukraine and Southern Africa, where 170,000 square kilometers are suspected of contamination [lagertha.ie, retrieved 2024] [YouTube, May 2024].
Founder in Multiple Arenas
The venture is led by solo founder Tom Weldon, an entrepreneur with a 35-year track record primarily in the medical device industry, where he holds more than two dozen patents [Vitamin Retailer, retrieved 2026]. His professional footprint, however, is notably broad. Public records show Weldon is simultaneously the CEO of Penguin Random House UK, Chairman and CEO of Ponce De Leon Health, and associated with Accuitive Medical Ventures LLC [Penguin Random House, April 2026] [LinkedIn, retrieved 2026] [Bloomberg Markets, retrieved 2026].
This raises immediate questions about bandwidth and operational focus for a hardware-intensive, field-deployment startup. Weldon’s experience in regulated industries and patent development is a clear asset for navigating technical and certification hurdles. The execution risk, however, lies in the day-to-day demands of building, testing, and selling physical systems in a demanding, low-margin humanitarian sector.
Early Institutional Support
Despite its early stage, Lagertha has secured institutional backing in Ireland, a signal that the concept has passed initial technical and commercial diligence. The company has raised approximately €100,000 in pre-seed funding, with support from Enterprise Ireland’s Pre-Seed Start Fund and the Irish accelerator NDRC [Enterprise Ireland, retrieved 2026] [NDRC, retrieved 2026].
This early capital validates the problem space and provides runway for prototype development. The backing from Enterprise Ireland, a government agency, also suggests alignment with Irish industrial and export policy, potentially opening doors to diplomatic channels in key regions.

The Competitive and Operational Minefield
The demining technology sector is niche but not empty. Lagertha’s most direct conceptual competitor appears to be Mine Kafon, known for its wind-powered, rolling detection devices. The competitive landscape for drone-based detection, however, is still forming. The larger challenge may not be a single rival, but the entrenched processes and procurement cycles of a conservative, risk-averse customer base.
For a hardware startup, the path from prototype to reliable field operation is fraught. The risks for Lagertha are not abstract.
- Technical validation. The AI’s false-positive and false-negative rates in varied soil conditions and against different mine types are unproven. A single missed detection is catastrophic.
- Operational focus. The founder’s simultaneous leadership of multiple, unrelated companies is an unusual configuration for a capital-intensive startup requiring deep, hands-on attention.
- Sales motion. Selling to NGOs, government agencies, and UN bodies involves long sales cycles, complex procurement, and a need for proven, auditable results before scale adoption.
The company’s answer to these risks rests on its cost thesis and modular design. By being cheaper and attaching to existing drone fleets, it lowers the barrier to trial. The IMAS-aligned output is designed specifically to fit into the existing reporting workflows of clearance organizations [lagertha.ie, retrieved 2024].
The Next Twelve Months
The immediate milestone is clear: translate the €100,000 pre-seed into a functional, field-testable prototype. Success in the coming year will be measured not by revenue, but by validated technical partnerships. Landing a collaborative field trial with a recognized humanitarian organization like The HALO Trust or Norwegian People’s Aid would be a more significant signal than any additional funding round.
Given the capital requirements for hardware iteration and inventory, a seed round is a likely next step. The investor pitch will hinge on demonstrating that first proof-of-concept data, moving the narrative from a compelling idea to a tool that has actually identified a subsurface threat from the air.
Enterprise Ireland and NDRC have placed an initial €100,000 bet on Tom Weldon’s vision of a cheaper detector. The question for the next check-writers is whether a drone can reliably find a landmine before a farmer, or a child, does.
