What 61N does

61N Solutions Oy is a Tampere, Finland-based IT consulting firm founded in August 2022 that designs, develops, and modernizes critical information systems for the Finnish defense and security sector. The company serves the Finnish Defense Forces, security authorities, and government agencies, delivering five integrated service areas: performance development consulting, implementation leadership and systems integration, critical systems continuity, system portfolio modernization, and custom mission-critical systems. When off-the-shelf products are insufficient, 61N builds custom systems including analytics, AI solutions, and supporting infrastructure tailored to operational requirements. The firm employs a technology-agnostic stack spanning Kotlin/Java backends, TypeScript/React frontends, Python/Spark data pipelines, Kubernetes/OpenShift containerization, and AWS/Azure cloud platforms.

The business model is professional services delivery through direct enterprise sales to government clients. Revenue is generated from consulting engagements and custom systems development rather than packaged software products. The firm operates as part of the Krosswise consortium and Reaktor's Fusion Ecosystem, which provide access to broader expertise and academic partnerships with the University of Jyväskylä and University of Turku. 61N grew from 7 employees at founding to nearly 60 professionals by September 2025, with leadership transitioning in September 2024 from founder Janne Mansikkamäki to Heikki Härkönen and a new Operations Director role created in spring 2025. Geographic expansion to Helsinki is underway with stated plans for future international markets.

Distinctive capabilities include a research-led AI practice covering reinforcement learning for battlefield optimization, NLP, multimodal data fusion, and predictive analytics, supported by senior staff with doctoral credentials — including the first comprehensive Finnish doctoral dissertation on AI in Western armed forces. The firm markets itself primarily through direct enterprise sales, content marketing on its corporate blog, and employer branding via a Teamtailor-powered career site.

Direct peers

• Reaktor: Sister company within the Fusion Ecosystem that 61N's CEO previously led. Comparable Finnish IT consultancy with national-security-adjacent work, similar modern engineering culture, and the closest organizational peer for benchmarking scale, delivery model, and talent strategy.
• Futurice: Finnish software consultancy with significant defense and public-sector work and overlapping talent pool (multiple 61N leaders came from Futurice). Comparable in delivery model, technology stack, and ability to staff complex IT programs for government clients.
• Combitech: Nordic technical consulting and defense engineering firm owned by Saab. Directly comparable as a Nordic defense IT/systems engineering peer, with similar focus on mission-critical systems, security-cleared talent, and government clients across Sweden and the Nordics.
• Insta DefSec: Finnish defense and security software and systems integration company, one of 61N's main domestic competitors. Direct overlap in critical defense IT, command and control systems, and AI for defense; notably, 61N's COO Maija Wirlander joined from Insta DefSec, underscoring the talent and competitive overlap.

Emerging players

• Palantir Technologies: Defense and intelligence software platform with deep Western military footprint, including AI/data platforms for situational awareness and decision support. Overlaps with 61N's AI and data-fusion capabilities for defense, and is increasingly partnering with Nordic defense customers.
• Bittium: Finnish defense and critical communications specialist with software and tactical communications offerings. Adjacent competitor for Finnish defense IT budgets, particularly in secure communications and tactical systems that complement 61N's command-and-control work.

Broad incumbents

• Leidos: Large US-headquartered defense IT and systems integration prime serving US and allied governments. Comparable in delivering mission-critical defense IT services, and a reference point for the scale 61N could reach with sustained Nordic/NATO expansion.
• Accenture Federal Services: Global defense and public-sector IT services firm that competes for large-scale defense modernization programs. Comparable in delivering consulting, systems integration, and AI/analytics services to government clients, though at substantially larger scale.
• Saab: Large Nordic defense prime with a broad portfolio spanning sensors, systems, and digital defense solutions. Comparable as an incumbent that 61N may partner with or compete against for Finnish and broader Nordic defense IT modernization contracts.
• Kongsberg Defence & Aerospace: Norwegian defense and aerospace prime with growing digital and defense IT capabilities. Relevant incumbent peer given shared Nordic/NATO customer base and overlapping interest in defense AI and command-and-control systems.
