For most of the postwar era, defence procurement moved on a timescale measured in decades: an aircraft programme could outlast the political administration that commissioned it. That cadence is breaking. Software updates, not new hulls, now determine whether a given platform can counter this month's threat.
The shift has a name inside the industry: software-defined defence. It describes a platform philosophy in which sensors, weapons and vehicles are treated as comparatively interchangeable hardware, while the intelligence lives in a continuously updated software layer.
Market context
Three forces are converging to accelerate this transition: sustained European rearmament budgets, a maturing bench of venture-funded companies, and battlefield evidence — most visibly from Ukraine — that inexpensive, software-updatable autonomous systems can offset expensive legacy platforms.
The primes that survive this decade won't be the ones with the best hardware. They'll be the ones that figured out how to ship software as fast as the threat changes.Defence-sector portfolio manager, European growth fund
The companies setting the pace
No single company defines the category, but a handful have become reference points. Anduril's Lattice platform popularised a shared autonomy layer that can run across many hardware types. Helsing has taken a comparable approach from a European base.

Funding growth at this pace typically precedes a consolidation phase. We'd expect the next 18 months to produce more acquisitions of point-solution autonomy vendors by the larger software-defined platforms.
Procurement is the real bottleneck
Capital has moved faster than the institutions meant to spend it. The UK's new autonomy framework is one of the more closely watched attempts to solve this.
| Company | HQ | Focus | Latest stage | Outlook |
|---|---|---|---|---|
| Helsing | Germany | AI perception & EW | Series D | Positive |
| Anduril Industries | United States | Software-defined platforms | Private | Positive |
| Tekever | United Kingdom | Maritime ISR / UAS | Series C | Neutral |
| Palantir Technologies | United States | Decision platforms | Public | Watch |
Risks and open questions
Risk Box
Valuations across the sector now assume sustained double-digit budget growth across multiple NATO members. A shift toward fiscal consolidation would compress the funding environment faster than most current models assume.
Methodology
Funding figures are drawn from disclosed rounds tracked by the Defense Mandate Capital Tracker, cross-referenced against PitchBook and company announcements.
Outlook
Expect the next phase of this story to be told less through funding announcements and more through procurement outcomes — which frameworks actually convert into fielded capability.
