A material science startup with technology originating at Rice University has announced it has closed its seed round of funding.

DexMat raised $3 million in funding in a round led by Shell Ventures with participation from Overture Ventures, Climate Avengers and several individuals. The company transforms hydrocarbons, renewable fuels, and captured carbon into its flagship product Galvorn.

“DexMat presents an opportunity to capture methane, an abundant and inexpensive resource, and use it to replace materials such as steel, aluminum, and copper with a more sustainable option. We are excited to be part of DexMat’s journey going forward and to realize their ambitions,” says Aimee LaFleur, investment principal at Shell, in a news release.

Alongside the announcement of the seed round, DexMat has named Bryan Guido Hassin as its new CEO. Hassin, who was previously a member of the company's board of directors, has been at the helm of multiple climate tech startups and most recently co-founded Third Derivative. Dmitri Tsentalovich, the previous CEO, is transitioning to CTO.

“Before joining DexMat, as CEO of Third Derivative, I was introduced to easily over 2,000 innovative new concepts and technologies. DexMat’s solution was one of the most impactful I came across, which is precisely why I’m so excited to be joining the team,” says Hassin in a news release. “The opportunity to eventually cut up to 3 gigatons of CO2 annually in one of the most underserved markets of the clean energy transition — heavy industry — was too important for me to pass by.”

The product impacts the climate tech space on two levels. First, in the production process, the carbon is 'locked' into the Galvorn material structure as a form of long-term carbon storage, according to the release. On the use side, the material displaces carbon-intensive materials — like steel, aluminum, and copper.

"The world's net zero future is entirely dependent on electrifying everything and decarbonizing the built environment," says Shomik Dutta, co-founder and managing partner at Overture Ventures, in the release. "Metals like copper and steel sit at the heart of these trillion-dollar markets, and DexMat's technology promises carbon-negative, lighter, and stronger versions of what we currently mine and melt. Companies like this can help cement America's leadership in the most important transition of our lifetimes."

DexMat was founded to commercialize materials science technology that originally developed in the Rice University laboratory of co-founder Professor Matteo Pasquali. According to the release, the company was built on over $20 million in non-dilutive funding — including grants from from the Air Force Research Laboratory, Air Force Office of Scientific Research, U.S. Department of Energy, NASA, Advanced Functional Fabrics of America, and the National Science Foundation — with Rice University included in the list of original investors.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.
