Finnish Startup SEATOM Chosen for NATO's 2026 Innovation Programme

SEATOM Selected for NATO's Accelerator Programme

In a major development for the maritime and defense industries, SEATOM, a Finnish startup, has been chosen for NATO's prestigious Defence Innovation Accelerator for the North Atlantic (DIANA) 2026 Challenge Programme. The startup's novel approach, which involves an affordable modular micro nuclear reactor system designed for extreme environments, was recognized under NATO DIANA's Operations in Extreme Environments Challenge program. This selection not only highlights SEATOM's commitment to innovation but also its role in addressing critical defense and security challenges prevalent in harsh environments such as the Arctic.

About SEATOM and Its Innovative Technology

Based in Porvoo, Finland, SEATOM is pioneering solutions in nuclear propulsion systems aimed at both civilian and dual-use applications. Their groundbreaking reactor technology promises to redefine maritime energy solutions, particularly in challenging conditions where traditional energy sources may not suffice. Roope Marttila, the co-founder and co-CEO of SEATOM, emphasized the timeliness of their selection, stating, "This is the right time for nuclear, as national and international regulations are being reformed and public perception now favors maritime nuclear more than any other viable option out there."

This innovative nuclear reactor technology is anticipated to play a significant role in sustainable maritime solutions, especially in light of current trends favoring clean energy alternatives. As part of the NATO DIANA programme, SEATOM will be integrated into a network of experts and mentors, enhancing its technological readiness and enabling deeper connections with NATO's end-users.

Joining the NATO DIANA Programme

The upcoming six months will see SEATOM actively participating in DIANA's Core Programme, collaborating with the DualTech Accelerator located in Turin, Italy. This engagement provides unprecedented access to advanced testing infrastructure, essential defense market insights, and direct interaction opportunities with NATO resources. During this period, the company will receive an initial funding installment of €100,000, with potential for additional financial resources designated for testing, evaluation, and validation purposes, commonly referred to as TEVV activities.

Furthermore, SEATOM will be involved in operational exercises alongside NATO Allied forces, amplifying its exposure and capabilities in the defense sector. By participating in this challenge, the company aspires not only to refine its nuclear technology but also to solidify its standing within the NATO cooperative defense framework.

Future Outlook and Events

SEATOM is poised to emerge as an influential player in the defense industry, joining a select group of innovative companies addressing vital areas within Western security and defense. With the programme set to launch officially on January 19, 2026, the highlight will be an International Demo Day scheduled in Paris for June 2026, where various technological innovations, including SEATOM's, will be showcased to a global audience.

As SEATOM progresses through the NATO DIANA challenge, it represents the forefront of defense innovation, revolutionizing how nuclear technology can secure future maritime operations while concurrently contributing to environmental sustainability.
