• Delian Alliance Industries, founded by former Apple engineer Dimitrios Kottas, announced Tuesday it’s raised $14 million in Series A funding to accelerate production of its affordable and autonomous defense systems. 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 Projects Group” (SPG), working on autonomous systems for robots—and, for many years, was the team most closely associated with Project Titan, Apple’s since-canceled car project. But a few months after leaving Apple in 2021, he began work on Delian Alliance Industries, a defense startup designed “to protect 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 production” 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 product 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 production. 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 researching machine learning, said Silicon Valley also taught him about the importance of embracing “moonshot” projects, which are ambitious ideas that may result in revolutionary, rather than evolutionary, change. Some of its prototypes 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 technologies 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 proven our systems in mission critical environments and will now ramp up production 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 program aimed at providing cheap loans for member countries so they can buy military equipment together. As you might imagine, defense companies and startups like Delian are reaping the benefits of these policy shifts.

• Prime Day is Amazon’s most important sales event of the year. It all started when Diego Piacentini, an Amazon executive, noticed the success of Alibaba’s Singles Day in China and pitched Jeff Bezos that his “everything store” do something similar. Today, Prime Day generates billions in revenue for the tech giant.

Amazon Prime Day is one of the most lucrative and influential retail events in the world. Last year, it generated a whopping $14.2 billion in sales, according to Capital One.

But the origins of this sales juggernaut trace back to a single executive’s vision and a pivotal pitch to Amazon’s founder, Jeff Bezos.

The genesis of Prime Day

In the early 2010s, Amazon’s international business was led by Diego Piacentini, a seasoned executive who had joined the company in 2000 after a successful career at Apple. As Amazon’s global footprint expanded, Piacentini was tasked with finding new ways to energize both customers and the company’s growing base of Prime members outside the U.S.

According to Brad Stone’s book “Amazon Unbound,” Piacentini was inspired by the explosive success of Alibaba’s Singles Day in China, which had quickly become the world’s largest online shopping event. So Piacentini pitched Jeff Bezos on Amazon having its own event, and Bezos was into it, thinking the primary goal would be to drive sales to Prime, the company’s subscription service.

After obtaining Bezos’s blessing, Amazon executives reportedly went back and forth on when to hold their event. But according to Stone’s book, Amazon leadership eventually opted not to go toe-to-toe with Alibaba’s Singles Day, which is held in November, and instead decided on having their own sale during the summer months, a traditionally slower time in retail. The logic there was customers would have enough money during the summer months since they weren’t doing all of their holiday shopping just yet, and that also meant there would be ample warehouse space.

Amazon Prime Day got the green light in January 2015, with the goal of launching on July 15 to coincide with Amazon’s 20th anniversary.

From ‘Project Piñata’ to ‘Christmas in July’

The internal codename for the Amazon Prime Day initiative was “Project Piñata.” Meagan Wulff Reibstein, a young product manager who spent seven years at Amazon before departing for a VP role at Zillow, was assigned to execute the plan. She traveled to Amazon’s international hubs—Tokyo, London, Paris, and Munich—to convince suppliers and partners to participate in the event.

The first Prime Day launched across nine countries, and the response was immediate. In Japan, the massive surge in traffic crashed the local website. Across Europe and the U.S., customers snapped up deals, even as some complained about limited inventory and underwhelming discounts.

Despite technical hiccups and mixed reviews, the numbers told a different story: 34.4 million items sold and 1.2 million new Prime members added in a single day. “It was Christmas in July quite frankly—a bigger day than Black Friday,” Amazon CFO Brian Olsavsky told investors on an earnings call the following week.

Amazon Prime Day has only grown since then. In its second year, Prime Day sales jumped by 60%. By 2019, Amazon expanded the event to be two days, and in 2025, the event now spans four days. It kicked off on Tuesday, July 8, and runs until Friday, July 11—a full 96 hours to take advantage of deals.

Prime Day has become a crucially important event for Amazon. Last year, consumers in 23 different countries purchased over 300 million items with an average order value approaching $60. Notably, 88% of all Prime Day consumers were Prime members, and 85% of customers had been Prime members for over a year. And people tend to buy lots of Amazon products, specifically: Last year, Prime Day shoppers bought more Amazon Fire Sticks than any other item.
