It's been a busy past year or so for Nicolaus Radford, founder and CEO of Nauticus Robotics. He's taken his company public at a difficult time for the market, launched new partnerships with the United States Marine Corps, and even welcomed a new family member.

Originally founded in 2014 as Houston Mechatronics, Nauticus Robotics has designed a fleet of underwater robots and a software platform for autonomous operations. Radford caught up with InnovationMap about these recent milestones for him and the company in an interview.

"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," he tells InnovationMap. "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." Read more.

A Houston startup that combines unique sensor technology with software analysis has raised its next round of funding to — according to Founder and CEO Josh Teekell — turbocharge its sales.

SmartAC.com's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. Teekell says he's focused on sales, and he's going to do that with the $22 million raised in the series B round that closed this month. He says the company will also grow its team that goes out to deploy the technology and train the contractors on the platform.

"This funding really buys us a couple years of runway through the end of next year and allows us to focus on getting to cash flow breakeven, which is right around our wheelhouse of our abilities here in the next 12 months," Teekell says. "In general, we've accomplished everything we'd be able to accomplish on the hardware side, and now it's just about deployment." Read more.

Researchers at the University of Houston and in Germany released a proof-of-concept paper this month that uncovers a new, fuel efficient means of transportation that they say could one day make air travel and traditional freight transport obsolete.

"I call it a world-changing technology,” Zhifeng Ren, director of the Texas Center for Superconductivity at UH and author of the paper, said in a statement.

Published in the journal APL Energy, the paper demonstrates a new way of using superconductors to move vehicles along existing highways while transporting liquified hydrogen at the same time. Until now, the costs of using superconductivity for transportation has held back innovation in the field. This model also reduces the need for a separate specialized pipeline system to transport liquified hydrogen that's able to keep the fuel source at minus 424 degrees Fahrenheit. Read more.

Researchers at the University of Houston and in Germany released a proof-of-concept paper this month that uncovers a new, fuel efficient means of transportation that they say could one day make air travel and traditional freight transport obsolete.

"I call it a world-changing technology,” Zhifeng Ren, director of the Texas Center for Superconductivity at UH and author of the paper, said in a statement.

Published in the journal APL Energy, the paper demonstrates a new way of using superconductors to move vehicles along existing highways while transporting liquified hydrogen at the same time. Until now, the costs of using superconductivity for transportation has held back innovation in the field. This model also reduces the need for a separate specialized pipeline system to transport liquified hydrogen that's able to keep the fuel source at minus 424 degrees Fahrenheit.

The model uses a similar concept to what's behind already existing magnetically levitating trains that operate on a magnetized rail, with superconductors embedded in the train's undercarriage. In Ren's model, superconductors would be embedded into existing highway infrastructure and magnets added to the undercarriages of vehicles. Liquified hydrogen would be used to cool the superconductor highway as vehicles move across it.

The idea could apply to trains, cargo trucks, and even personal cars, according to the paper. Better yet, the vehicles could travel up to 400 mph while on the highway. Drivers would then use the vehicle's traditional or electric motor once they exit.

"Instead of 75 mph, you could go 400 mph, from Houston to Los Angeles, or Houston to New York in just a few hours," Ren said in a statement.

Ren adds that this method would also require drivers to consume less fuel or power, cutting down on cost and environmental impact.

Technical and economic details still need to be addressed. But Ren believes "the project’s potential long-term economic and environmental benefits, would outweigh the upfront costs," according to a statement.

The paper joins a number of other innovative concepts coming out of UH in recent months. Recently, a research team at the university upgraded at-home rapid COVID-19 testing to make results more detectable via glow-in-the-dark materials.

Late last year the university also opened its

new tech transfer facility, and early this year it signed an agreement with India to bring a data center focused on energy to campus.

University of Houston designs device that instantly kills COVID-19

ZAPPING COVID-19

While the world rushes to find a COVID-19 vaccine, scientists from the University of Houston have found a way to trap and kill the virus — instantly.

The team has designed a "catch and kill" air filter that can nullify the virus responsible for COVID-19. Researchers reported that tests at the Galveston National Laboratory found 99.8 percent of the novel SARS-CoV-2 — which causes COVID-19 — was killed in a single pass through the filter.

Zhifeng Ren, director of the Texas Center for Superconductivity at UH, collaborated with Monzer Hourani, CEO of Medistar, a Houston-based medical real estate development firm, plus other researchers to design the filter, which is described in a paper published in Materials Today Physics.

Researchers were aware the virus can remain in the air for about three hours, which required a filter that could quickly remove it. The added pressure of businesses reopening created an urgency in controlling the spread of the virus in air conditioned spaces, according to UH.

Meanwhile, to scorch the virus — which can't survive above around 158 degrees Fahrenheit — researchers instilled a heated filter. By blasting the temperature to around 392 F, they were able to kill the virus almost instantly.

The filter also killed 99.9 percent of the anthrax spores, according to researchers.

A prototype was built by a local workshop and first tested at Ren's lab for the relationship between voltage/current and temperature; it then went to the Galveston lab to be tested for its ability to kill the virus. Ren says it satisfies the requirements for conventional heating, ventilation and air conditioning (HVAC) systems.

"This filter could be useful in airports and in airplanes, in office buildings, schools and cruise ships to stop the spread of COVID-19," said Ren, MD Anderson Chair Professor of Physics at UH and co-corresponding author for the paper, in a statement. "Its ability to help control the spread of the virus could be very useful for society."

Medistar executives are also proposing a desk-top model, capable of purifying the air in an office worker's immediate surroundings, Ren added.

Developers have called for a phased roll-out of the device, with a priority on "high-priority venues, where essential workers are at elevated risk of exposure — particularly schools, hospitals and health care facilities, as well as public transit environs such as airplanes."

The hope, developers add, is that the filter will protect frontline workers in essential industries and allow nonessential workers to return to public work spaces.

Texas booms as No. 3 best state to start a business right now

Innovation Starts Here

High employment growth and advantageous entrepreneurship rates have led Texas into a triumphant No. 3 spot in WalletHub's ranking of "Best and Worst States to Start a Business" for 2026.

Texas bounced back into the No. 3 spot nationally for the first time since 2023. After dropping into 8th place in 2024, the state hustled into No. 4 last year.

Ever year, WalletHub compares all 50 states based on their business environment, costs, and access to financial resources to determine the best places for starting a business. The study analyzes 25 relevant metrics to determine the rankings, such as labor costs, office space affordability, financial accessibility, the number of startups per capita, and more.

When about half of all new businesses don't last more than five years, finding the right environment for a startup is vital for long-term success, the report says.

Here's how Texas ranked across the three main categories in the study:

  • No. 1 – Business environment
  • No. 11 – Access to resources
  • No. 34 – Business costs

The state boasts the 10th highest entrepreneurship rates nationwide, and it has the 11th-highest share of fast-growing firms. WalletHub also noted that more than half (53 percent) of all Texas businesses are located in "strong clusters," which suggests they are more likely to be successful long-term.

"Clusters are interconnected businesses that specialize in the same field, and 'strong clusters' are ones that are in the top 25 percent of all regions for their particular specialization," the report said. "If businesses fit into one of these clusters, they will have an easier time getting the materials they need, and can tap into an existing customer base. To some degree, it might mean more competition, though."

Texas business owners should also keep their eye on Houston, which was recently ranked the 7th best U.S. city for starting a new business, and it was dubbed one of the top-10 tech hubs in North America. Workers in Texas are the "third-most engaged" in the country, the study added, a promising attribute for employers searching for the right place to begin their next business venture.

"Business owners in Texas benefit from favorable conditions, as the state has the third-highest growth in working-age population and the third-highest employment growth in the country, too," the report said.

The top 10 best states for starting a business in 2026 are:

  • No. 1 – Florida
  • No. 2 – Utah
  • No. 3 – Texas
  • No. 4 – Oklahoma
  • No. 5 – Idaho
  • No. 6 – Mississippi
  • No. 7 – Georgia
  • No. 8 – Indiana
  • No. 9 – Nevada
  • No. 10 – California

Houston lab-test startup seeks $1M for nationwide expansion

Testing Access

Health care industry veteran Jim Gebhart knew there had to be a better way for patients to access lab services, especially those with high health insurance deductibles or no insurance at all.

“This challenge became deeply personal when a close family member developed a serious illness, and we struggled to secure prompt appointments,” Gebhart tells InnovationMap. “It’s incredibly frustrating when a loved one cannot receive timely care simply because of provider shortages or the limited capacity of traditional clinics.”

Driven by the desire to knock down lab-test barriers, Gebhart founded Houston-based TheLabCafe.com in 2024. The platform provides access to low-cost medical tests without requiring patients to carry health insurance. TheLabCafe serves patients in six states: Texas, Georgia, Louisiana, Nevada, New Mexico and Oklahoma. Gebhart, the startup’s CEO, says that by the end of March, LabCafe will be offering services in 20 more states and the District of Columbia.

Gebhart has spent more than 30 years in the lab industry. His career includes stints at Austin-based Clinical Pathology Laboratories, Ohio’s Cleveland Clinic Laboratories and Secaucus, New Jersey-based Quest Diagnostics.

“Since nearly 80 percent of disease diagnoses rely on laboratory testing, I decided to leverage my background to create a more accessible, self-directed process for individuals to order blood and urine tests on their own terms — when and where they need them,” says Gebhart.

So far, Gebhart is self-funding the startup. But he plans to seek $700,000 to $1 million in outside investments in late 2026 to support the nationwide expansion and the introduction of more services.

TheLabCafe contracts with labs for an array of tests, such as cholesterol, hepatitis, metabolic, testosterone, thyroid and sexually transmitted infection (STI) tests. A cholesterol test obtained through TheLabCafe might cost $29, compared with a typical cost of perhaps $39 to $59 without insurance.

A health care professional reviews every test, both when the test is ordered and when the results are delivered, often within 24 hours. After receiving test results, a patient can schedule a virtual visit with a health care professional to go over the findings and learn potential treatment options.

Gebhart says TheLabCafe particularly benefits uninsured patients, including those in Texas. Among the states, Texas has the highest rate of uninsured residents. U.S. Census Bureau data shows 21.6 percent of adults and 13.6 percent of children in Texas lacked health insurance in 2024.

“Uninsured patients often pay the highest prices in the health care system,” Gebhart explains. “We address this by offering straightforward pricing and convenient access to testing without requiring insurance.”

“Our rates are intentionally set to remain affordable, helping individuals take a proactive approach to their health,” he adds. “Regular testing enables people to identify potential health issues early and track their progress as they make lifestyle changes. Ultimately, you can’t measure improvement without data — and laboratory results provide that data.”

Houston geothermal startup secures $97M Series B for next-gen power

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.
