Small defense industry artificial intelligence startups are suddenly fielding calls from generals, combatant commanders and deep-pocketed investors, after the souring relationship between the Pentagon and its once-favored AI vendor, Anthropic, reinforced the need to diversify and increase the number of AI providers for the military.

In the weeks since the Department of Defense's troubled relationship with Anthropic burst into public view and led to the company being kicked out of the US military, new defense-focused AI companies like Smack Technologies and EdgeRunner AI say they have experienced a shift in interest that would have been unimaginable just months ago. They have received a surge of overtures about possible contracts and meeting requests and been approached by investors who previously showed no interest.

The Pentagon's growing animosity toward its top AI provider, Anthropic, has opened up opportunities for smaller rivals, who have long sought a foot in the door to the most lucrative government contractor in the world. A defense contract can lead to more business with other branches of the US government, and is a useful signal of trust and safety for potential commercial clients.

"We've seen a massive increase in demand from customers and the government to get AI solutions fielded since Anthropic was declared a supply-chain risk," said Tyler Sweatt, CEO of Second Front, a company that helps technology firms meet the requirements needed to operate on secure Pentagon networks. "Our customers are turning to us as the Pentagon turns to them to deploy quickly in the wake of the Anthropic blowup."

Since the Pentagon deemed Anthropic's products a "supply-chain risk" in March and the two sides became embroiled in a lawsuit, the military has expressed increasing interest in AI startups like Smack Technologies, saying, "We want more, we want demos, let's talk about how we can move faster," said Andrew Markoff, co-founder and chief executive of the 19-person startup based in El Segundo, California. In late March, a judge temporarily blocked the Pentagon's blacklisting of Anthropic.

Tyler Saltsman, co-founder and chief executive of EdgeRunner AI, described a similar experience. His company had been waiting more than a year for a Space Force contract to clear the Pentagon's procurement machinery. It was signed within weeks of the Anthropic situation breaking into the open. "I can't prove that the Anthropic drama sped this up," Saltsman said, "but I have a sneaky suspicion it did."

"The Pentagon will continue to rapidly deploy frontier AI capabilities to the warfighter through strong industry partnerships across all classification levels,” a Pentagon official said.

One Pentagon technologist has previously told Reuters that the falling-out with Anthropic, and the realization that the Defense Department was heavily dependent on one AI provider, forced the department to diversify AI providers.

Smack's marine corps contract speeds up

For Smack, the clearest example of the post-Anthropic acceleration involves the Marine Corps. The company won a contract with the Marine Corps in March 2025 and delivered a successful prototype by October — software that compresses what is normally a months-long operational planning process into roughly 15 minutes.

Despite the successful prototype, momentum stalled. Full production had been budgeted for fiscal year 2027 — meaning October 2027 at the earliest. Through the 2025 holiday period and into early 2026, there was no clear direction.

Then the Anthropic uproar occurred. Within weeks, Smack was invited to multiple meetings with the Marine Corps focused on a single question: how fast can this move into production this year? Markoff said there was "very specific guidance and movement and energy" toward getting the prototype ready for combat operations in 2026 — an acceleration of more than a year.

The shift extended beyond the Marines. Smack holds contracts with the Navy and Air Force, and Markoff said interest came in nearly immediately from U

S Special Operations Command, and others.

EdgeRunner, which is deploying with the Army Special Forces groups and has received a contract with the Space Force, said the Navy has also dramatically sped up engagement. Meetings that had been biweekly or monthly are now happening multiple times a week.

Both EdgeRunner and Smack are now racing to get their systems operating at higher security classification levels — the gateway to the most operationally significant use cases and the largest military contracts.

EdgeRunner said the military has told the company it can get to IL-6, a security designation enabling access to secret and top-secret data, within three months — a timeline Saltsman described as remarkable, given that the process normally takes 18 months or longer. The acceleration, he said, is being driven partly by pressure from Pentagon leadership to cut through procurement bureaucracy, and partly by the urgency the Anthropic situation has injected into the department's AI strategy.
