In the wake of a leadership reshuffling and amid lingering financial troubles, publicly traded Nauticus Robotics, a Webster-based developer of subsea robots and software, has netted more than $12 million in a second tranche of funding.

The more than $12 million in new funding includes a $9.5 million loan package.

Nauticus says the funding will accelerate certification of the company’s flagship Aquanaut robot, which is being prepared for its inaugural mission — inspecting a deep-water production facility in the Gulf of Mexico that’s owned by a major oil and gas company.

The new funding comes several weeks after the company announced a change in leadership, including a new interim CEO, interim chief financial officer, and lead general counsel.

Former Halliburton Energy Services executive John Gibson, the interim CEO, became president of Nauticus last October and subsequently joined the board. Gibson replaced Nauticus founder Nicolaus Radford in the CEO role. Radford’s LinkedIn profile indicates he left Nauticus in January 2024, the same month that Gibson stepped into the interim post.

Radford founded what was known as Houston Mechatronics in 2014.

Victoria Hay, the new interim CFO at Nauticus, and Nicholas Bigney, the new lead general counsel, came aboard in the fourth quarter of 2023.

“We currently have the intellectual property, prototypes, and the talent to deliver robust products and services,” Gibson says in a news release. “Team Nauticus is now laser-focused on converting our intellectual property, including both patents and trade secrets, into differentiated solutions that bring significant value to both commercial and government customers.”

A couple of weeks after the leadership shift, the NASDAQ stock market notified Nauticus that the average closing price of the company’s common stock had fallen below the $1-per-share threshold for 30 consecutive trading days. That threshold must be met to maintain a NASDAQ listing.

Nauticus was given 180 days to lift its average stock price above $1. If that threshold isn’t reached during that 180-day period, the company risks being delisted by NASDAQ. The stock closed February 6 at 32 cents per share.

The stock woes and leadership overhaul came on the heels of a dismal third-quarter 2023 financial report from Nauticus. The company’s fourth-quarter 2023 financial report hasn’t been filed yet.

For the first nine months of 2023, Nauticus reported an operating loss of nearly $20.9 million, up from almost $11.3 million during the same period a year earlier. Meanwhile, revenue sank from $8.2 million during the first nine months of 2022 to $5.5 million in the same period a year later.

Nauticus went public in September 2022 through a SPAC (special purpose acquisition company) merger with New York City-based CleanTech Acquisition Corp., a “blank check” company that went public in July 2021 through a $150 million IPO. The SPAC deal was valued at $560 million when it was announced in December 2021.

Nauticus recently hired investment bank Piper Sandler & Co. to help evaluate “strategic options to maximize shareholder value.”

One of the strategic alternatives involves closing Nauticus’ previously announced merger with Houston-based 3D at Depth, which specializes in subsea laser technology. When it was unveiled last October, the all-stock deal was valued at $34 million.

Houston subsea tech company makes acquisition, plans to grow renewables biz

all aboard

A Houston company that harnesses the power of robotics hardware and programing for underwater use has made an acquisition.

Nauticus Robotics Inc. (NASDAQ: KITT) announced it has acquired 3D at Depth Inc., a Colorado-based company with a subsea light detection and range, LiDAR, technology for inspection and data services. The deal closed for approximately $34 million in stock, before certain purchase price adjustments and the assumption of debt, per the news release.

“The future of subsea services lies in autonomy, data gathering, and analytics,” Nicolaus Radford, Nauticus’ founder and CEO, says in the release. “LiDAR has long since been core to terrestrial autonomy and by adding 3D’s capabilities to the Nauticus Fleet, we enhance autonomous vehicles in the offshore market. This acquisition increases the value of Nauticus’ fleet services and positions the Company to capitalize on data acquisition and analytics for subsea operations.”

The acquisition expands Nauticus' capabilities for its autonomous underwater suite of technology for its customers. With the deal, Nauticus will assume 20 patents secured or pending by acquiring 3D, which generated $9.8 million in revenue last year and is slated to grow revenue by more than 20 percent in 2023, according to the release.

“In addition to the compelling strategic and financial benefits of this deal, the acquisition will add momentum to our commercial growth trajectory,” Radford continues. “By adding 3D’s technology, offshore inspection and data service, and experienced team, Nauticus expands our addressable market and accelerates our customer penetration in the offshore energy and renewables industries.”

Founded in 2009, 3D will operate as a division of Nauticus when the deal closes sometime before the end of the year. Nauticus will also assume approximately $4.1 million of debt in the transaction.

“The Nauticus Robotics and 3D at Depth combination creates a compelling solution for the subsea market and should help improve our products and services for all our clients,” Carl Embry, founder and CEO of 3D at Depth, says in the release. “We believe the integration of our unique subsea multi-dimensional data collection and processing with an emerging leader in subsea robotics creates a differentiated offering for customers seeking safer, cleaner, lower-cost subsea services.”

Nauticus, founded by Radford in 2014 as Houston Mechatronics, went public via a blank check company last year.

Engineering tech co. expands collaboration with Houston robotics startup in $2.1M contract extension

underwater moves

A major customer of Webster-based Nauticus Robotics, a maker of autonomous oceangoing robots, has bulked up its current contract.

Reston, Virginia-based Leidos has tacked on a $2.1 million extension to its existing contract with Nauticus. That brings Leidos’ total financial commitment from $14.5 million to $16.6 million.

In partnership with Leidos, Nauticus is developing next-generation underwater drones for business and military customers. These unmanned underwater vehicles are being designed to carry out tasks that are dangerous or impossible for human divers to do, such as mapping the ocean floor, studying sea creatures, and monitoring water pollution.

“This very important work combines great attributes from each company to deploy a truly novel subsea capability,” says Nicolaus Radford, founder and CEO of Nauticus.

Based on Nauticus’ Aquanaut product, these robots will feature the company’s toolKITT software, which supplies artificial intelligence capabilities to undersea vehicles.

“This work is the centerpiece of Nauticus’ excellent collaboration with Leidos,” says Radford, “and I look forward to continuing our mutual progress of advancing the state of the art in undersea vehicles.”

Founded in 2014 as Houston Mechatronics, Nauticus adopted its current branding in 2021. Last year, Nauticus became a publicly traded company through a merger with a “blank check” company called CleanTech Acquisition Corp.

During the first six months of 2023, Nauticus generated revenue of nearly $4 million, down from a little over $5.2 million in the same period last year. Its operating loss for the first half of 2023 was almost $12.7 million, up from slightly more than $5.2 million during the same time in 2022.

Nauticus attributes some of the revenue drop to delays in authorization of contracts with government agencies.

The company recently lined up a $15 million debt facility to bolster its operations.

“I’ve never been more optimistic about the future of Nauticus. We employ some of the best minds in the industry, and we are positioned with the right product at the right time to disrupt a $30 billion market,” Radford said earlier this month. “Demand from potential customers is high, but constructing our fleet is capital-intensive.”

More good news for Nauticus: It recently signed contracts with energy giants Shell and Petrobras. Financial terms weren’t disclosed.

The Shell contract involves a project in the Gulf of Mexico’s Princess oil and gas field that Nauticus says could lead to millions of dollars in additional contracts over the next few years. Shell operates the offshore field, which is around 40 miles southeast of New Orleans, and owns a nearly 50 percent stake in it.

Co-owners of the Princess project are Houston-based ConocoPhillips, Spring-based ExxonMobil, and London-based BP, whose North American headquarters is in Houston. In July, the Reuters news service reported that ConocoPhillips was eyeing a sale of its stake in the Princess field.

Under the contract with Petrobras, whose U.S. arm is based in Houston, Nauticus will dispatch its Aquanaut robot to support the Brazilian energy company’s offshore activities in South America. Nauticus says this deal “opens up a potential market opportunity” in Brazil exceeding $100 million a year.

Q&A: Houston robotics entrepreneur on IPO, military innovation, and more

automation nation

Almost a decade ago, Nicolaus Radford founded a robotics company that automated underwater operations for heavy industry customers. Now, the company provides its robotics-as-a-service business to customers across industry, providing key analytics, risk-managed monitoring, and emission-reducing service.

Nauticus Robotics (Nasdaq: KITT) went public via SPAC last year, and Radford, CEO and founder, sat down with InnovationMap earlier this year to share the unique challenges he faced with the IPO, the company's partnerships with the United States Marine Corps, and more. Check out the shortened Q&A below and head to InnovationMap for the full conversation.

InnovationMap: Tell me about life after IPO. What’s been surprising for you leading your company through the transition and now on the other side of IPO?

Nicolaus Radford: I'll tell you what, it’s the hardest thing I ever did in my professional career by a factor of 10. It was a very exceptionally challenging period of time. It took a long to complete the transaction, and the market was just changing under our feet. Rules were and regulations were changing — were we grandfathered in or were we not?

I'm part of some business organizations and, and some of those confidential relationships have turned into friendships. And a couple of them call me and they're like, “we're really worried. We think this is going to be we don't know if you're going to get it done. And we just want you to be aware that you're not you may not get it done.” It is a little scary because once you engage in it, you're running quite a tab with bankers and law firms and all sorts of things. And if you don't complete the deal, it just might kill the company.

But we did it. We were one of a few people last year to actually get a deal over the line. I'm very proud of that. I think it speaks to the quality of the deal that we had. The macro economic environment was exceptionally difficult. It remains to be very difficult today. But we had strong backing from our strategic investors and our partners that were already on the cap table. They put a tremendous amount of money into the deal.

You know, I look back on it and it's, you know, ringing the Nasdaq bell when we listed, and giving that speech at the podium — it was a surreal moment. I remember when I was standing there looking at the Nauticus logo on the seven-story Nasdaq tower, having as many people in the company as we could bring, and just sharing that moment with all of them.

I was excited but cautious at the same time. I mean, the life of a CEO of a public company at large, it's all about the process following a process, the regulations, the administration of the public company, the filings, the reportings — it can feel daunting. I have to rise to the occasion to tackle that in this the next stage of the company.

IM: You’re working with the military on a project that adapts Nauticus tech for Marine Corps use. What’s it been like working with the military on this project?

NR: We've probably worked with military interests for the last six years, but all of the things that we have been doing have been extremely confidential and hush. Now we've been able to work with customers that have a stronger public facing persona, and the Defense Innovation Unit is one of those.

Their charter is it's quite literally looking for commercial technology and adapting that towards military applications, and so it's been nice to be able to show the utility and the application of of a lot of our technology and what we've been working on for so long as it's applied on a broader scale to the big services, whether it's the Navy or the Marine Corps.

Both of the programs we’re working on are all about mine countermeasures, and mines are really, really difficult, especially underwater mines. We've been we've been applying all of Nauticus’s broad technology portfolio to being able to search autonomously and being able to identify and neutralize threats in the water. I love that mission because anytime we can remove our service men and women from these situations, that's just the right thing to do.

IM: What’s next for Nauticus?

NR: What’s next is tough to talk about, because I can only talk about what’s already been published. I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow. We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.

Houston robotics company secures deal with Brazilian energy giant

sea change

Houston-based Nauticus Robotics, a developer of autonomous ocean robots, has landed a deal to supply its equipment to one of the world’s largest energy companies — a deal that eventually could blossom into $100 million worth of contracts.

Under the deal, Nauticus will dispatch its Aquanaut autonomous subsea robot to support offshore oil exploration activities carried out by Brazil’s Petrobras. Specifically, Aquanaut — propelled by artificial intelligence-enabled software — will supervise infield inspection services over a two-month span.

The deal with Brazil’s Petrobras represents Nauticus’ entry into the South American market and puts Nauticus in a position to score several Petrobras contracts that could collectively be valued at $100 million. Both companies are publicly traded.

Nicolaus Radford, founder and CEO of Nauticus, says Brazil offers a significant market opportunity for his company, as South America’s largest nation boasts one of the world’s most active offshore energy basins.

“A contract with [a] worldwide leading operator for Nauticus speaks to the state-of-the-art technologies of our autonomous robots as we further penetrate the global markets,” Radford says in a news release.

Petrobras is one of the world’s biggest offshore operators, managing 57 platforms, operating 10,000 miles of oil and gas pipelines, and producing the equivalent of 2.6 million barrels of oil per day. The company generated $124.47 billion in revenue last year.

Founded in 2014, Nauticus posted revenue of $11.4 million in 2022. The company went public last year through a $560 million merger with a special purpose acquisition company (SPAC). Nauticus recently opened a new office in The Ion, in addition to their Webster office.

“I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow,” Radford told InnovationMap in May. “We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.”

Fervo Energy leads Time’s top green tech companies of 2026

top spot

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

  • No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
  • No. 71 Plus Power, which develops, owns and operates battery energy storage systems
  • No. 98 Utility Global, whose technology enables industrial decarbonization
  • No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
  • No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

  • The 2025 Houston Innovation Awards named it Scaleup of the Year
  • MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
  • Time named Fervo one of the 100 Most Influential Companies of 2025
  • Fervo was hailed as the Global Cleantech Group 100 North American Company of the Year
  • Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span
Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

3 strategies to strengthen the Gulf Coast as a global energy hub

The View from HETI

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone.

This unmatched concentration of refining, petrochemical manufacturing, pipelines, ports, and technical talent makes the Gulf Coast one of the most critical energy hubs in the world. But maintaining that leadership in a rapidly evolving global market will require intentional collaboration, faster technology commercialization, and strengthened supply chain resilience.

In fall 2025, the Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) convened national laboratories, Gulf Coast universities, and industry leaders to examine how to reinforce the region’s long-term competitiveness. Participants included Argonne, Oak Ridge, Lawrence Berkeley, the National Energy Technology Laboratory (NETL), and the National Laboratory of the Rockies, alongside Gulf Coast academic institutions and energy and chemical companies. Here are the key findings and takeaways from the workshop.

1. Supply Chain Resilience Requires Structured Industry–Lab Collaboration

Resilience—diversity of supply, operational flexibility, and rapid recovery—was a recurring theme. Recent disruptions exposed vulnerabilities in tightly interconnected energy and manufacturing systems.

National laboratories provide capabilities that complement Gulf Coast industrial scale, particularly at early and mid technology readiness levels (TRLs 1–7), before full commercial deployment. Examples include:

  • Advanced manufacturing and AI-enabled validation of critical components (Oak Ridge).
  • Materials scale-up and techno-economic modeling to move from lab discovery to industrial relevance (Argonne).
  • Pilot-scale testing for severe-service alloys, chemical conversion, and process innovation (NETL).
  • Integrated energy systems modeling to assess grid resilience and system disruptions (National Laboratory of the Rockies).

Recommendation: Organize targeted Gulf Coast industry missions to national laboratories focused on critical supply chains—power equipment, high-heat industrial processes, novel catalysts, refining, and grid infrastructure—to identify joint development opportunities and reduce time to commercialization.

2. Modeling, AI, and Open-Access Platforms Can Bridge the Technology Gap

A persistent barrier to innovation is the gap between scientific discovery, applied development, and commercial deployment. Universities often operate at TRLs 1–3, national labs at 1–7, and industry at 7–9. Bridging these silos requires shared modeling tools, high-performance computing, and structured feedback loops.

National labs maintain open-access platforms capable of:

  • Simulating grid expansion, investment, and dispatch decisions.
  • Modeling cradle-to-gate industrial material flows.
  • Optimizing complex energy and chemical systems.
  • De-risking carbon capture, critical mineral recovery, and advanced manufacturing integration.

Recommendation: HETI should convene structured training and feedback sessions on these public modeling platforms—ensuring Gulf Coast industry can apply, improve, and help guide further development of tools critical to regional competitiveness. Federal initiatives such as the Genesis Mission, focused on AI-accelerated scientific discovery, further expand opportunities for Gulf Coast participation.

3. Time to Commercialization Is the Ultimate Competitive Metric

The lithium-ion battery is a cautionary example: while pioneered in U.S. labs, large-scale manufacturing leadership shifted overseas. Without strategic intervention, U.S. firms are projected to capture less than 30% of domestic lithium battery cell value by 2030.

Successful DOE-backed consortium models show that mission-aligned, multi-partner collaboration reduces development timelines and strengthens domestic manufacturing know-how. However, public–private partnership mechanisms such as CRADAs and Strategic Partnership Projects can be time-intensive.

Recommendation: The Gulf Coast should actively engage DOE and national laboratories to streamline public–private partnership pathways, improve intellectual property clarity, and expand industry access to laboratory infrastructure.

The Path Forward: A Gulf Coast Consortium Model
The workshop’s central conclusion was clear: the Gulf Coast should formalize collaboration through a regional industry–academia–laboratory consortium.

Such a model could:

  • Co-locate national lab researchers within the region.
  • Share modeling data and analytical capabilities.
  • Establish open-access pilot facilities that complement lab infrastructure.
  • Harmonize IP frameworks to accelerate licensing and deployment.

With its dense industrial ecosystem, technical workforce, and decision-making concentration, the Gulf Coast is uniquely positioned to serve as a national demonstration hub for advanced energy and chemical manufacturing.

If industry, universities, and national laboratories align around a shared regional strategy, the Gulf Coast can:

  • Accelerate commercialization timelines.
  • Strengthen critical supply chains.
  • Unleash a world-class technical workforce.
  • Reinforce U.S. leadership in strategic energy and chemical sectors.

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.
