Saronic Valuation History, Stock and IPO: Every Funding Round from Series A to the $9.25 Billion Series D

Saronic is valued at $9.25 billion after a $1.75 billion Series D led by Kleiner Perkins, announced March 31, 2026, its latest priced round as of November 14, 2026. Saronic is a private company: it has no stock ticker, has not filed for an IPO, and its shares do not trade on any public exchange.

The Austin, Texas, maker of autonomous surface vessels was founded in 2022. In under four years its valuation rose from $1 billion in July 2024 to $9.25 billion, and it went from building 24-foot drone boats to opening a shipyard program for vessels up to 850 feet. This page lists every Saronic funding round with sources, explains what the money is buying, and answers the most common questions about Saronic stock and a possible IPO.

Saronic valuation history: every funding round

Saronic itself announced valuations for its Series B and Series D. The Series C valuation comes from press reports. No valuation was published for the Series A.

The seed figure is our inference: TechCrunch reported in October 2023 that Saronic had raised about $70 million in total including the $55 million Series A, which leaves roughly $15 million before it. Aggregator sites disagree on the seed's size, date and lead, and Saronic has not published it, so treat that row as approximate.

How much has Saronic raised?

About $2.6 billion in announced equity, by our count. Chief executive Dino Mavrookas told CNBC in February 2025 that the company had raised almost $850 million including the Series C, according to TechCrunch. Adding the $1.75 billion Series D gives roughly $2.6 billion. Saronic has not published a cumulative total.

The jumps between rounds are steep. The valuation quadrupled from the Series B to the Series C (from $1 billion to $4 billion in seven months) and rose about 2.3 times to the Series D.

Saronic Series D: who invested and why

Kleiner Perkins led the $1.75 billion Series D, and Sullivan & Cromwell, which advised Saronic, described it as a preferred stock round at initial closing. New investors included Advent International, Bessemer Venture Partners, DFJ Growth and BAM Elevate. Franklin Templeton returned, alongside the company's earlier backers.

Saronic said the money would fund Port Alpha, its planned shipyard; expand production in Louisiana and Texas; scale its vessel family from the 24-foot Corsair to the 180-foot Marauder "and beyond"; and develop maritime AI. At the time it had more than 1,300 employees, an Austin headquarters of more than 500,000 square feet, hubs in San Diego and Washington, DC, and operations in the UK and Australia.

What Saronic builds and who buys it

Saronic's products are autonomous surface vessels (ASVs) of increasing size: Corsair (24 feet), Mirage, Cipher and Marauder (180 feet), plus Echelon software for mission planning and command and control. Its customer base is mainly the US Navy, with growing allied interest.

• Corsair production contract: Saronic's Series D release cites a $392 million US Navy production contract awarded in 2025.
• Marauder, MUSV Marketplace: on September 29, 2026, the Navy announced production Other Transaction agreements with Galliano Marine Services, HII and Saronic, each for 10 Medium Unmanned Surface Vessels at an average procurement cost of $40 million per vessel. Saronic says Marauder completed more than 140 test scenarios over eight days of continuous operations in the at-sea phase (Saronic). First deliveries are due before the end of fiscal 2027 (FY2027). In the same announcement, Leidos, PAC MAR and Sea Machines received $15 million awards for completing their prototype agreements.
• Landing Craft Utility: the Navy has also contracted Saronic to build crewed Landing Craft Utility (LCU) vessels at Port Alpha, the company says; no value has been published.

Saronic revenue: what is public

Saronic does not publish revenue, and none of its funding announcements include a revenue figure. Estimates from private-market data providers circulate online, but they are not company disclosures and we do not repeat them here.

What can be sized is the contract backlog the company has announced. The 2025 Corsair production contract is $392 million. The September 2026 Marauder award covers 10 vessels at an average of $40 million each, or about $400 million at the Navy's stated average cost, although the Navy did not publish the exact value of each agreement. The Landing Craft Utility contract has no published value. Contract ceilings and averages are not the same as booked revenue: they are paid out as vessels are delivered and accepted.

Founders, partners and related companies

Saronic was started in 2022 by chief executive Dino Mavrookas, a former Navy SEAL, with co-founders including Doug Lambert and Vib Altekar, who later moved into new executive roles, according to company announcements. Its announced partners include Palantir, NVIDIA, Samsung Heavy Industries, Hornbeck Offshore, Vigor Marine Group and Lloyd's Register, and it signed a memorandum of understanding with Taiwan's National Chung-Shan Institute of Science and Technology.

Saronic has also teamed with Castelion, the hypersonic missile startup, to demonstrate launching a hypersonic weapon from an autonomous vessel. Partnerships of this kind matter for the valuation story: they position Saronic as a platform that carries other companies' payloads, not only a boat builder.

Port Alpha: the Saronic shipyard in Brownsville

On July 16, 2026, Saronic picked Brownsville, Texas, for Port Alpha, a shipyard planned with more than $3 billion of investment. It starts on 835 acres at the Port of Brownsville, with room to grow to nearly 4,400 acres, and is designed for vessels up to 850 feet. Saronic says it will create up to 10,000 direct jobs over a decade; construction was planned to start in 2026 and operations in 2028. Saronic has since announced a groundbreaking and selected Syncrolift to supply the shiplift.

Port Alpha adds to the shipyard in Franklin, Louisiana, that Saronic bought in early 2025 (the former Gulf Craft yard), where it is investing $300 million to add 300,000 square feet and build Marauder. These are capital-heavy projects, which helps explain why Saronic raises in billions rather than hundreds of millions.

Is Saronic publicly traded? Saronic stock and IPO

No. As of November 14, 2026, Saronic is privately held, has no ticker symbol, and has not filed a registration statement with the Securities and Exchange Commission (SEC). There is no confirmed IPO date. Any website offering "Saronic stock" is offering exposure to private shares through a secondary platform or a special purpose vehicle (SPV), not stock listed on Nasdaq or the NYSE.

Secondary marketplaces publish indicative prices for Saronic shares based on trades and orders between private parties. These are estimates, not priced funding rounds, and they are generally open only to accredited investors. The company's last priced valuation remains the $9.25 billion Series D.

Will Saronic go public? The company has not commented on IPO timing in the materials reviewed for this article. Two signals are worth watching: production revenue from the Navy contracts above, and whether Saronic needs public-market capital to finish Port Alpha.
