The Nordic defence-tech boom has produced drones, sensors, missiles and software. Stendr wants to go one layer deeper and build what it calls the foundational technology stack for a new Nordic defence prime.

The Oslo company announced a $5.4 million oversubscribed pre-seed round, co-led by Rainfall, ACME and Skyfall, with participation from Sisyphus, Antler, StartupLab, Off Piste and Andøya Ventures, plus angel investors. The company says it is one of the largest pre-seed rounds in Nordic defence tech history.

The founder twist is the part people will remember first. CEO Aleksander Leonard Larsen previously co-founded Sky Mavis, the company behind Axie Infinity. Gaming money to drone defence. It sounds odd until you remember that modern warfare now has user interfaces, real-time infrastructure and cheap autonomous objects everywhere.

Stendr’s initial focus is drone defence: detecting, tracking and responding to autonomous drone threats with AI-driven multi-sensor technology embedded in cost-efficient hardware platforms. The company is deliberately talking about full-stack hardware and software, not a dashboard that sits politely on top of someone else’s system.

Larsen’s line in the announcement is blunt: drones are cheap, autonomous and everywhere, while defence systems built for a previous era can’t keep pace. That’s the thesis in one sentence. Europe’s security problem isn’t only a shortage of equipment. It’s a mismatch between the speed of threats and the speed of procurement, integration and software iteration.

Defence primes are usually built over decades. Stendr is trying to borrow startup tempo without pretending defence is just another SaaS market. That’s a hard balance. Possibly the whole company.

Before Stendr, Larsen helped scale Sky Mavis and Axie Infinity to a reported $3 billion valuation, building real-time infrastructure for millions of users. Crypto gaming is not air defence. No serious person should pretend otherwise.

Yet the operational muscles do rhyme: high-pressure systems, adversarial environments, fast iteration, distributed users and a need to make complex infrastructure feel usable. The battlefield has become a place where software decisions travel fast and hardware needs to be cheap enough to deploy in volume.

The company’s technical team adds more direct relevance. CTO Robin Alexander Holm Pedersen brings more than 15 years of full-stack engineering experience across AI systems, digital identity infrastructure and hardware development. Head of Hardware Markus Leonhard Hansen previously co-founded and led Gungnir of Norway, taking a hardware product from concept to global customer recognition. Not a conventional defence founding team. That may be the appeal.

Rainfall’s Ron Rofe said he’s backing Larsen again, citing resilience, talent density and an ability to solve problems in unusual ways. ACME and Skyfall co-leading gives the round both U.S. and Nordic venture weight, while Andøya Ventures adds a Norwegian aerospace and defence adjacency.

Stendr’s language is explicitly European: sovereign systems, democratic nations, a Nordic defence prime. That’s not just branding. Europe is trying to reduce dependence on non-European defence technology while moving faster than legacy procurement cycles usually allow.

There’s tension in that setup. Global venture capital wants speed and scale. Sovereign defence wants control, trust and export discipline. Stendr has to satisfy both. Easy on a pitch deck, harder once customers ask where every component comes from.

Norway has deep maritime, energy and industrial capabilities, but its startup brand has often been softer: marketplaces, SaaS, fintech, climate. Stendr adds to a sharper category forming across the Nordics, where defence, autonomy and sensing are becoming credible venture targets.

The pre-seed size matters because it gives the company room to hire, build hardware, test and survive the slow parts of defence sales. A $1 million round can build a prototype. A $5.4 million round can start building a system company.

The hard question is whether Europe can create new defence primes quickly enough without simply becoming a feature supplier to the old ones. Stendr’s answer is in the name it wants to claim. Prime. Not vendor.

Watch whether this story turns into customer deployments, follow-on financing, regulatory attention or a copycat wave across the Nordic ecosystem. The first announcement is the easy part. The second proof point is where the market starts telling the truth.
