A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth."

The fresh funding will go toward advancing the company's Xeus HTS wire technology for key energy transition applications by expanding MetOx's U.S.-based manufacturing capabilities to meet demand.

"This funding marks a pivotal step in our mission to revolutionize the energy and technology sectors with our advanced power delivery technology and accelerate delivery for our customers and partners. HTS is critical to enhancing the efficiency of our electric grid and enabling technological developments that, in many cases, would not be viable or even possible without superconductor technology," adds Bud Vos, CEO of MetOx. "Support from investors such as Centaurus and NSV not only provides the financial resources and strategic support required for accelerated scaleup, but also validates the broad reach of our technology across energy, data center, medical, and defense industries."

HTS wire technology is critical for the energy transition, especially amid rising data center growth, and for next generation wind turbines and interconnections.

MetOx's technology originated out of the University of Houston and was founded in 1998 by Alex Ignatiev, UH professor emeritus of physics and a fellow of the National Academy of Inventors. Last year, the company secured $3 million in funding from the U.S. Department of Energy to support the advancement of its proprietary manufacturing technology for its HTS wire.

"MetOx's HTS technology aligns with our systems-level research and offers a unique opportunity to dramatically accelerate the energy transition," says Ian Samuels, founder and managing partner at NSV. "MetOx's Xeus wire stands to be a force multiplier in clean energy generation and high-power transmission and distribution, enabling load growth and the deployment of power-dense data centers. NSV is excited to support MetOx as it scales domestic manufacturing capacity."

Plans revealed for $2 billion expansion of Houston convention district

coming soon

Mayor John Whitmire and Houston First Corporation shared a new master plan for the George R. Brown Convention Center and its surrounding area last week. The plan features expanded exhibition space, a living roof, a pedestrian plaza with access to Toyota Center and more.

The project will be funded by the state’s portion of incremental Hotel Occupancy Tax revenue growth within a three-mile radius of the GRB for 30 years, which is estimated to total about $2 billion, according to a release from Houston First.

The first phase of the project, which is slated to be completed by 2028, will focus on developing a 700,000-square-foot convention facility known as GRB South.

GRB South will feature:

  • Two exhibition halls, totaling 150,000 square feet
  • A 50,000-square-foot multipurpose hall that opens to the new Central Plaza
  • The 100,000-square-foot Central Plaza, an extension of the Avenida Plaza that will connect to Discovery Green and Toyota Center
  • Atrium flex hall totaling 25,000 square feet
  • 225,000 square feet of contiguous exhibit space
  • A 60,000-80,000-square-foot ballroom
  • Ground-level spaces for retail and restaurants
  • A central atrium, providing each level with natural light

The design of the space is inspired by the Houston area's native prairies and will use low-carbon materials, high-efficiency building systems with rainwater collection and water-reduction strategies. A living roof on top of the GRB South will also have the potential for solar integration.

"It is imperative for us to stay competitive and meet the needs of our meetings and convention customers,” Michael Heckman, president and CEO of Houston First, said in the release. “This project will not only accomplish that but will establish a gathering space that will be the epicenter for entertainment, sports, and city-wide events, accentuating our ability to capitalize on Houston's unique offerings.”

The full campus renovation is expected to wrap in 2038, and construction will be managed in phases. Houston First reports that construction should not impact events currently scheduled as GRB.

“This project is truly transformative for downtown Houston, a lasting legacy that will solidify our position as a top-tier convention and entertainment destination,” Mayor John Whitmire said in the release. “Most importantly, we are creating a space that will build community, foster connection, and shape the future of Houston.”

Tech company floats plan for futuristic shipyard on Texas Gulf Coast

Anchors Away

Armed with $600 million in fresh funding, Austin-based Saronic Technologies has set its sights on building a shipyard for producing remotely operated military vessels — and the futuristic shipyard could be located along the Texas Gulf Coast.

The shipyard, dubbed Port Alpha, would manufacture unstaffed midsize and large Navy ships known as “maritime drones.” Defense Newsreported that Texas — with the Gulf Coast being a prime target — is among the places under consideration for the shipyard. A timeline for construction of the shipyard hasn’t been set, and a cost estimate for the project hasn’t been revealed.

“A core principle of Saronic is that we design our vessels for autonomy from the keel up,” Saronic co-founder and CEO Dino Mavrookas, a former Navy SEAL, says in a news release. “We will take the same approach with Port Alpha, designing a shipyard from the ground up to produce at a speed and scale not seen since World War II.”

Saronic says Port Alpha would boost the U.S. shipbuilding industry, which is practically nonexistent. Consulting giant McKinsey & Co. reported in 2024 that the U.S. has gone from building about 5 percent of the world’s ocean-going ships in the 1970s to about 0.2 percent today. China, Japan, and South Korea now dominate global shipbuilding.

“The last years have seen a degradation in the capacity for the United States to build ships and to manufacture core needs of the country. I am excited to back Saronic and its focus on revitalizing shipbuilding in America, while also building products to defend those interests,” says investor and tech entrepreneur Elad Gil, who led the $600 million funding round.

The $600 million round, announced February 18, pushes the value of Saronic to $4 billion. Investors in Saronic, founded in 2022, include Gil, General Catalyst, a16z, Caffeinated Capital, and 8VC.

Last year, Saronic raised $175 million from investors, lifting the company’s value to $1 billion. In 2023, the startup collected $55 million from investors.

In the past three years, Saronic has focused on manufacturing three small remotely controlled vessels, or “maritime drones,” for the Navy: the six-foot-long Spyglass, 14-foot-long Cutlass, and 24-foot-long Corsair. Port Alpha would specialize in much bigger remotely controlled ships for the Navy. The Navy has expressed interest in assembling a modern fleet that combines staffed and unstaffed vessels.

Saronic’s nearly 420,000-square-foot factory in Austin manufactures the Spyglass, Cutlass and Corsair boats.

“The velocity and economics of warfare have fundamentally evolved, and several of our own team have witnessed firsthand how unmanned systems became true force multipliers in Afghanistan and in other theaters of conflict,” says Paul Kwan, managing director of General Catalyst.

Tesla poised to bring ‘megafactory’ to Houston area with 1,500 jobs

Tesla Talk

Tesla is expected to bring a “megafactory” and 1,500 manufacturing jobs to the Houston area.

According to various news reports this week, Tesla intends to spend $200 million on a facility in Brookshire, Texas. The Waller County Commissioners Court approved tax abatements on March 5 for the new plant.

“We are super excited about this opportunity—1,500 advanced manufacturing jobs in the county and in the city," Waller County Precinct 4 Commissioner Justin Beckendorff said during Wednesday’s Commissioners Court meeting.

Tesla will lease two buildings in Brookshire's Empire West Business Park. According to documents from Waller County, Tesla will add $44 million in facility improvements. In addition, it will install $150 million worth of manufacturing equipment.

As part of the deal, Tesla will invest in property improvements that involve a 600,000-square-foot, $31 million manufacturing facility that will house $2 million worth of equipment and include improvements to the venue.

The facility will produce Tesla megapacks, which are powerful batteries to provide energy storage and support, according to the company. A megapack can store enough energy to power about 3,600 homes for one hour.

Tesla can receive a 60 percent tax abatement for 10 years. According to the tax abatement agreement, Tesla has to employ at least 1,500 people by 2028 in order to be eligible for the tax break.

In addition to the employment clause, Tesla also will be required to have a minimum of $75 million in taxable inventory by January 1, 2026, which will increase to $300 million after three years.
