Linda Lourie: What DIU’s Promotion Signals for Israeli Startup Strategy

If you think the Pentagon wants your cutting-edge prototype, Linda Lourie has a reality check: the Secretary of Defense isn’t interested in science fairs. He wants battle-tested tech that works today.

Lourie served as General Counsel of the Defense Innovation Unit (DIU), Associate General Counsel at DoW, and Assistant Director of the White House Office of Science and Technology Policy. And two weeks ago, DIU got promoted to a DoW Field Activity — a designation that changes everything for startups trying to break into defense. In a recent briefing for Israeli founders, Lourie explained what this actually means and why Israeli tech companies have a massive advantage right now.

Here’s what matters:

1. DIU just became a permanent front door for innovation — with budget visibility

A Field Activity is a cross-cutting organization that serves the entire Department of Defense, not just one service or office. This means DIU and its sister organization SCO (Strategic Capabilities Office) now have budget transparency and institutional permanence.

Translation: every time there’s a government transition, innovation offices wonder if they’ll survive. This designation foot-stomps that DIU isn’t going anywhere. It’s now the front door for defense innovation, and startups finally have one clear entry point instead of chasing innovation hubs scattered across the country.

2. All innovation now reports to one person — and that kills the “everyone wants their own helicopter” problem

DIU, along with all the service innovation arms (Air Force Works, Naval X, Army Fuse), now reports to Emil Michael, the CTO and Undersecretary of Defense for Research and Engineering.

Why this matters: defense services love to duplicate efforts. Everyone wants their own helicopter, their own weapons system, their own innovation hub. Now one person has visibility across all innovation pipelines and can say: “This solution you’re building? Three other services need it too.”

For startups, this means greater visibility and less redundancy. Your tech has a better shot at scaling across multiple services.

3. Portfolio Acquisition Executives manage problems, not requirements documents

The Pentagon just replaced Program Managers with Portfolio Acquisition Executives (PAEs). The difference isn’t just semantic.

Old way: “My job is to build the best tank possible — even if nobody wants tanks anymore.”

New way: PAEs manage a portfolio of capabilities and publish problems, not requirements. They can reallocate resources based on battlefield threats, adapt to emerging tech like Gen AI and autonomy, and focus on outcomes instead of procurement documents.

Lourie’s take as a former lawyer: “It’s hard for me to say this out loud, but there’s a recognition that the department needs to loosen requirements and create flexibility while maintaining accountability.”

4. Israeli tech has an unfair advantage post-October 7th

Here’s why Israeli startups are uniquely positioned: the founder and the warfighter are often the same person.

In the U.S., a technologist builds something, hands it to a warfighter, and hears: “It’s too heavy, it drains too fast, it doesn’t work.” That feedback loop takes months or years.

In Israel? The tech gets battle-tested immediately. The alignment between tech and battlefield need is instant. The speed and agility of development is unmatched.

Lourie was direct: “The Pentagon recognizes the advantage Israeli tech brings. This focus on speed, innovation, and cutting red tape is going to benefit Israeli founders and entrepreneurs.”

5. Don’t just knock on DIU’s door — create demand from the services first

Lourie’s tactical advice: figure out who your ideal customer is in the services (Army, Navy, Air Force, etc.), ideally the counterpart to whoever used your tech in Israel.

Then create demand from the service side. Get them to go to DIU and say: “We need this.”

DIU ultimately works with the services, so if you can generate pull from the customer, DIU is far more likely to bring you in as a portfolio company.

The bottom line

The Secretary of Defense doesn’t want science projects. He wants commercially successful technology that can be adapted for the warfighter with minor or moderate changes. If your tech is battle-tested, solves a real problem, and works today — not theoretically at scale — DIU’s promotion just opened a clearer, more permanent pathway to scale across the entire DoW.

But if you’re still pitching prototypes? You’re bringing a poster board to a gunfight.
