Kottas, who spent five years working in Apple’s secretive robotics lab, said he applied many learnings from his time in Silicon Valley to his four-year-old defense startup
Dimitrios Kottas spent years at Apple working in its secretive “Special jects Group” (SPG), working on autonomous systems for robots—and, for many years, was the team most closely associated with ject Titan, Apple’s since-canceled car ject
But a few months after leaving Apple in 2021, he began work on Delian Alliance Industries, a defense startup designed “to tect Europe and its allies.” On Tuesday, Kottas wrote a blog post announcing Delian had raised $14 million in a Series A funding round, led by Air Street Capital and Marathon Venture Capital, to “accelerate the duction” of affordable and autonomous systems that “defend against invasion and incursion at nation scale.” “We started Delian with a pilot of a single surveillance tower, but after just a few years we are now pursuing multiple nationwide deployments for our autonomous surveillance networks,” Kottas told Fortune. “Beyond this, we’re also helping allies to strike threats, as well as sense them
Our duct lineup ranges from autonomous detection to autonomous one way effectors” Rather than partnering with other defense companies and startups, Delian is borrowing a page from Apple, as well as Tesla, in that it’s choosing vertical integration as its key strategy around duction
It makes its own hardware—targeting systems, surveillance towers, drones, and more— as well as the software and systems, which are all “designed to be low cost, deployed in mass, and sovereign,” according to the company’s website. “Why do we pursue vertical integration? Speed,” Kottas told Fortune. “Look at the speed that Tesla moved versus its European competitors who sub-contracted out everything to hundreds of different suppliers
By bringing everything under one roof we can move at the speed we need to equip our allies in the face of a rapidly changing geopolitical landscape.” Kottas, who graduated from the University of Minnesota after years of studying computer science and reing machine learning, said Silicon Valley also taught him the importance of embracing “moonshot” jects, which are ambitious ideas that may result in revolutionary, rather than evolutionary, change
Some of its totypes reflect this concept, including explosive-laden high-speed boats that launch out of concealed locations to deter attacks by air or by sea. (Kottas told The Financial Times Delian is focused on “the maritime domain,” as airborne drones are a “very saturated market.”) “Our adversaries are arming themselves with emerging nologies at a rapid industrial scale,” Kottas wrote in a company blog post. “We’re in a race against time and should measure deployments in days, not decades
We’ve ven our systems in mission critical environments and will now ramp up duction internationally.” Delian, which has offices in Athens and London, says it’s built to integrate with “Europe’s evolving defense priorities.” The EU is having a defense boom right now: Ever since President Trump signaled that Europe is no longer a security priority for the U.S., several EU countries have accelerated their own investments as they attempt to reduce their dependency on U.S. support
At the NATO summit in June, all 32 member countries committed to raising security-related spending to 5% of GDP by 2035; separately, 18 EU countries have applied for billions of euros from The Security Action for Europe (SAFE) fund, which is a new $173 billion defense gram aimed at viding cheap loans for member countries so they can buy military equipment together
As you might imagine, defense companies and startups Delian are reaping the benefits of these policy shifts
