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]. 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 business. Its proposition is to turn any commercial drone into a humanitarian detection platform, providing 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. The AI software processes sensor data to identify potential threats and generates maps aligned with International Mine Action Standards (IMAS) [lagertha.ie, retrieved 2024]. 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 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]. 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 questions about bandwidth and operational focus for a hardware-intensive, field-deployment startup.
Early Institutional Support
Lagertha 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 Competitive and Operational Minefield
The risks for Lagertha are not abstract:
- Technical validation. The AI’s false-positive and false-negative rates in varied soil conditions are unproven.
- Operational focus. The founder’s simultaneous leadership of multiple, unrelated companies is an unusual configuration for a capital-intensive startup.
- Sales motion. Selling to NGOs and government agencies involves long sales cycles and complex procurement.
The Next Twelve Months
The immediate milestone is to translate the €100,000 pre-seed into a functional, field-testable prototype. Success in the coming year will be measured 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 significant signal.
