AUSTIN, Texas: Autonomous shipbuilder Saronic Technologies has raised $1.75 billion in a Series D round that values the company at $9.25 billion, the company announced on March 31. The round was led by Kleiner Perkins, with new investors Advent International, Bessemer Venture Partners, DFJ Growth, and BAM Elevate joining existing backers Andreessen Horowitz, 8VC, Caffeinated Capital, Elad Gil, and Franklin Templeton.
The raise more than doubles Saronic’s previous $4 billion valuation, set during a $600 million Series C in early 2025. It also places the four-year-old company among the most valuable private defense technology firms in the country, alongside other fast-scaling tech startups that have attracted massive capital in recent months. Saronic now employs more than 1,300 people across facilities in Texas, Louisiana, San Diego, and Washington, D.C.
Why a Startup Is Building Warships Faster Than the U.S. Government
The investment arrives at a moment when American shipbuilding capacity is under serious strain. A leaked U.S. Navy intelligence slide reported by The War Zone estimated that China has roughly 232 times the shipbuilding capacity of the United States. Meanwhile, 82 percent of U.S. Navy warships currently under construction are behind schedule, according to a March 2026 analysis from 19FortyFive.
Saronic’s pitch to the Pentagon: smaller, cheaper, autonomous vessels built at speeds traditional shipyards cannot match. The company completed its first 180-foot autonomous surface vessel, the Marauder, in under six months after acquiring its shipyard facility. That timeline would be unheard of in conventional naval procurement, where single destroyer programs routinely run years behind schedule and billions over budget.
CEO and co-founder Dino Mavrookas, who founded Saronic in 2022, has said the company is “confronting this challenge with a fundamentally new model of American shipbuilding” that combines first-principles engineering with software-defined production. The company currently builds two vessel classes: the 24-foot Corsair and the 180-foot Marauder, both designed for autonomous navigation, fleet coordination, surveillance, and patrol operations. Each vessel runs onboard autonomy systems that integrate sensors, navigation, and mission software, allowing the ships to operate under remote supervision rather than requiring full crew complements.
That approach directly addresses the Navy’s staffing problem. The U.S. Navy has struggled to recruit and retain sailors in recent years, making autonomous vessels that require minimal human oversight an increasingly attractive option. Mavrookas has described the shift as moving from “platforms that need hundreds of sailors to platforms that need a handful of operators monitoring a fleet from shore.”
What Does Saronic’s $1.75 Billion Raise Mean for Defense Tech Startups?
Saronic’s round signals that defense technology has become one of the fastest-growing categories in venture capital. A company that did not exist before 2022 now holds a $392 million Navy production contract, employs more than 1,300 people, and has raised capital at a pace that rivals the largest AI funding rounds of the past two years.
For context, Mistral AI raised $830 million days earlier for data center infrastructure. Saronic’s $1.75 billion dwarfs that figure and places it in rare company among private startups of any sector. The trajectory from founding to near-decacorn status in four years mirrors the velocity investors have come to expect from software companies, applied to something far more physical: building ships. Kleiner Perkins, the storied Silicon Valley firm that backed Amazon and Google in their early days, led the round.
The round also reflects a broader shift in Pentagon spending priorities. The U.S. military has signaled increasing interest in unmanned systems that cost a fraction of traditional warships. A conventional Navy destroyer costs upward of $2 billion and takes years to build. Autonomous surface vessels like Saronic’s Marauder can be produced faster and deployed in larger numbers, an approach the Navy calls “distributed lethality.” Mavrookas has stated the company aims to reach production levels not seen since World War II.
What’s Next for Saronic
The funding will go toward three immediate priorities. First, Saronic is expanding its shipyard in Franklin, Louisiana with a $300 million investment that will create 1,500 jobs and is expected to quintuple production capacity over the next 12 months. Second, the company is building Port Alpha, a next-generation shipyard in Texas designed for higher-volume manufacturing. Third, Saronic is expanding internationally, with new operations in the UK and Australia and additional hubs in San Diego and Washington, D.C.
The company’s production target of 20-plus ships per year by 2027 will be the clearest test of whether a startup can deliver on the promise of reshaping American shipbuilding. If Saronic hits that mark, it will have built a defense manufacturing operation of a scale that the U.S. has not seen from a private company in decades. For the venture capital industry, it would validate that defense tech can produce returns on par with the AI companies that have dominated funding headlines. The next major milestone to watch: whether the Navy exercises additional contract options beyond the initial $392 million, and whether Saronic’s autonomous vessels perform as advertised in real operational deployments.
