Quantum Systems: mapping European defense tech

The client and the question

A European family office new to defense investing asked Northern Lights to map the European defense tech landscape and identify where returns could be attractive.

Which segments of European defense tech offer venture-scale returns, and what does a winning scale-up look like?

Context

European defense budgets are rising sharply, and governments are opening procurement to younger companies with faster development cycles. Drones, counter-drone systems, autonomy and AI are attracting record investment.

Quantum Systems, the German maker of electric vertical take-off drones, has grown into one of Europe’s leading defense tech scale-ups, with drones used in operational environments and a growing international footprint.

In defense tech, the hardest part is not the prototype. It is the production contract.

Key questions

1. Segments. Which defense tech segments combine growing budgets, fast procurement and scalable economics?
2. Winners. What distinguishes scale-ups that reach production contracts from those that stall?
3. Entry. How should a family office build exposure: direct stakes, co-investments or funds?

Our approach

We combined defense procurement experience with a structured screen of the European landscape.

1. Landscape map. Segmentation of European defense tech by technology, maturity and customer.
2. Scale-up benchmark. Analysis of what successful companies did differently, using Quantum Systems as a reference case.
3. Portfolio options. Entry routes for a family office, with their return and risk profiles.

Key insights

1. Operational feedback is the new advantage.
   Companies whose products are used and improved in real operations iterate faster than competitors relying on trials. This accelerates both product maturity and customer trust.
2. Production capacity separates winners.
   The transition from prototype to volume production, with secure supply chains, is where most companies stall. Scale-ups that invest early in manufacturing capture the largest contracts.
3. Diversified customers reduce policy risk.
   Exposure to several countries and to dual-use markets reduces dependence on a single government budget and improves valuation resilience.

Outcome

1. A sector map with priorities.
   The client received a clear view of the most attractive segments and the companies leading them.
2. A screening framework.
   We provided criteria to evaluate defense tech opportunities quickly and consistently.
3. An entry strategy.
   The family office defined a staged approach combining fund commitments and selective co-investments.

For discussion

1. Is the current wave of defense tech investment sustainable once budgets stabilise?
2. What responsibilities come with investing in defense companies?
3. Can European defense tech scale-ups compete with US peers for global contracts?
