The traditional dual-use model assumes one technology serving two markets. What if the next wave of defense companies is built around a different idea entirely: one mission, two classes of customers?

For decades, defense startups have been built on a single, largely unquestioned assumption: the customer is the government.

Procurement is military. The budget comes from a ministry of defense. The end user is a soldier.

It’s such a fundamental assumption that most founders never stop to ask whether it still holds.

For most of modern history, it did. Governments protected strategic infrastructure because governments owned it. Ports, airfields, military bases, power generation, communications networks. The customer for defense technology was obvious because governments were defending assets that belonged to them.

But that relationship may be changing.

Today, some of the most strategically important infrastructure on Earth is owned and operated by private companies. Data centers. Fiber networks. Satellite constellations. Energy projects. Cloud infrastructure. Logistics networks.

While ownership may be private, the strategic importance often extends far beyond the company itself.

Recent conflicts have made this harder to ignore. Private companies increasingly operate infrastructure that governments, economies, and military organizations depend on. Once that happens, the line between commercial infrastructure and strategic infrastructure becomes harder to define.

The asset may be privately owned, but the consequences of disrupting it can be national.

In many ways, this isn’t a new phenomenon. Standard Oil was a private company, yet energy became a question of national power. AT&T was private, yet communications became a strategic asset. More recently, SpaceX demonstrated how quickly a commercial platform can become strategically significant.

The pattern itself is familiar. What may be changing is the scale.

And historically, whenever an asset became strategically important, an ecosystem emerged to protect it. Ports gave rise to maritime security. Aviation created its own security ecosystem. Energy infrastructure required specialized protection. Military installations, of course, built entire defense industries around them.

The question is whether the next generation of strategic infrastructure will create a new category of defense customers.

What This Means For Founders

For years, building a defense company meant accepting a particular reality. Long procurement cycles. Government budgets. A limited number of buyers. Success was often determined as much by procurement as by technology.

But what happens if strategic infrastructure itself becomes a customer?

A company protecting a military installation and a company protecting a privately owned satellite network may ultimately be solving versions of the same problem. The technology may not change much. The customer does.

That possibility raises a different question for founders. Not “how do I sell to the military?” but “who else has this problem?”

Because if critical infrastructure is increasingly owned by private organizations, then some of the largest future customers for defense technologies may not be defense organizations at all.

This matters because it changes the shape of the opportunity. For decades, defense founders had little choice but to navigate government procurement. If the customer base expands beyond governments, entirely new paths to scale could emerge. Faster-moving buyers. Different purchasing processes. Larger pools of capital. Organizations that face strategic threats but do not think of themselves as defense customers.

At the very least, it is worth asking whether we are looking at dual-use too narrowly.

Maybe the future is not one technology serving a military mission and a commercial mission. Maybe it is one mission serving two different customer types.

If the problem you solve is protecting critical infrastructure, perhaps the opportunity does not stop at governments.

The next generation of defense startups may still sell to militaries.

The more interesting question is whether they’re asking the right question in the first place.

Why is the military your only customer?
