A national hardtech-focused organization has named its 2024 batch of innovators, which includes the inaugural Houston-based cohort.

Activate named 62 fellows and 50 companies for is latest class, which spans Berkley, California — where the organization is based, Boston, New York, and Houston. Additionally, Activate Anywhere, the program's virtual and remote cohort, was named. According to Activate, it received over 1,000 applicants.

“People, not ideas alone, move the world forward. It is through the drive and determination of brilliant scientists and engineers that we are witnessing true progress,” says Activate CEO Cyrus Wadia in a news release. “Our current Activate Fellows and alumni are already pioneering innovative solutions that make a measurable difference. We’re thrilled to support the next 62 visionaries who will lead the charge in addressing our most urgent issues through groundbreaking science and technology.”

It's the first year Activate has hosted a Houston-based cohort. The organization initially announced its expansion early last year. The inaugural cohort has 11 fellows across energy, materials, life sciences, space, and other sectors.

The named Houston fellows who are working on energy transition solutions include:

  • Krish Mehta, founder and CEO of Phoenix Materials, a company that decarbonizes concrete using industrial waste.
  • Gabriel Cossio, founder and CEO of Nanoscale Labs, which is developing a high-throughput and low-cost nanomanufacturing system.
  • Matthew McDermott, founder and CEO of Refound Materials, a materials technology company developing more efficient synthesis recipes for accelerated materials discovery.
  • Alec Ajnsztajn, founder and CEO of Coflux Purification, a company that's creating a product that allows industries and water providers to cheaply remove forever chemicals to provide safe drinking water at a fraction of current energy use.
  • Ryan DuChanois and Yang Xia , co-founders of Solidec, a Houston-based startup redefining chemical manufacturing.

The rest of the cohort includes:

  • Meagan Pitcher, co-founder and CEO of Bairitone Health, which brings advanced imaging diagnostics into the home environment.
  • Wei Meng, co-founder and CEO of LumiStrain, a startup offering novel technology for mechanical strain mapping.
  • Sonia Dagan of Atolla Tech, which is developing a lidar and machine-learning algorithm for identifying and quantifying airborne insects.
  • Rodrigo Alvarez-Icaza, founder and CEO of Elysium Robotics, a company that's replacing electric motors with muscle-like actuators to enable massive deployment of highly capable and low-cost robotic systems.
  • Blake Herren, CEO and Co-founder of Raven Space Systems, which is modernizing composite manufacturing with 3D printing and Industry 4.0 solutions to build the factories of the future.

Houston cleantech company closes $12M seed round

fresh funding

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"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.

SLB and NVIDIA expand partnership to scale AI across energy sector

AI partnership

Houston-based energy technology company SLB has expanded its 18-year tech collaboration with chipmaker NVIDIA to include the development of an “AI factory for energy.”

Through their partnership, SLB and NVIDIA will create AI infrastructure and models built around SLB’s existing digital platforms to help energy companies scale AI for data and operations.

In addition to the development of the “AI factory,” SLB will:

  • Provide modular design services to enhance NVIDIA’s blueprint for building, launching and operating gigawatt-scale AI data centers. In this case, modular design involves manufacturing data center components off-site.
  • Use NVIDIA’s AI infrastructure to improve the processing of large datasets and AI models across SLB’s digital platforms.

Energy companies generate vast amounts of operational data, which can slow down and silo decision-making, SLB says. By combining NVIDIA’s Omniverse libraries and its Nemotron open models with SLB’s digital and AI platforms, the companies aim to more rapidly transform data into actionable insights.

Omniverse libraries are sets of prebuilt 3D elements, such as objects, surfaces and interactive features, that make it easier to construct detailed virtual spaces without having to design everything manually. They’re commonly used for building immersive environments, digital replicas of real-world systems and simulation scenarios.

Nemotron open models are AI models that are freely available to download and modify. Instead of relying on a hosted service, you can run them on your own infrastructure and tailor them to fit specific needs.

Vladimir Troy, vice president of AI infrastructure at NVIDIA, says the energy sector is at the forefront of AI driving a “new industrial revolution.”

“The winners in AI will be companies with the best data, the deepest domain expertise, and the ability to scale,” Demos Pafitis, SLB’s chief technology officer, added. “By collaborating with NVIDIA to advance modular data center construction and harness our domain expertise and digital platforms, we’re enabling the energy industry to deploy AI at scale and transform operational data into smarter decisions.”
