Nearly 100 energy tech startups pitched at the 19th annual Rice Alliance Energy Tech Venture Forum this week — and over a third of those companies are based in the Houston area.

At the conclusion of the event — which took place on Thursday, September 15, at Rice University, and included a day full of company pitches, panels, and thought leadership — 10 startups were deemed the most promising among their peers. The group was voted on by investors attending office hours ahead of the event.

The Rice Alliance for Technology and Entrepreneurship facilitated nearly 700 meetings between 70 investor groups and 90 ventures, according to the organization. The group of presenting companies included participants from Rice's Clean Energy Accelerator's first two cohorts.

Here are 10 of the energy tech industry's most promising companies — and the technology they are working on that's set to disrupt the status quo.

Arolytics

Based in Calgary and founded in 2018, Arolytics is a software company that specializes in emissions management, ESG performance, and regulatory compliance. The company's platform is able to save its users up to 40 percent of their associated measurement costs and emissions management.

Atargis Energy

Atargis Energy is based in Pueblo, Colorado, and is a a member of Rice's second cohort of its Clean Energy Accelerator. The company has developed a twin hydrofoil-based wave energy converter that creates electric power from ocean waves. The technology is paired with real-time sensors and machine learning to optimize power conversion.

Compact Membrane Systems

Based in Delaware, Compact Membrane Systems, is pioneering membrane systems for decarbonizing hard-to-abate chemical manufacturing and industrial carbon capturing. The technology has the potential to revolutionize the chemicals industry.

Dimensional Energy

Dimensional Energy, based in Ithaca, New York, is transforming carbon dioxide into sustainable aviation fuels and products at market competitive prices. The technology integrates carbon capture, electrolysis, and Fischer Tropsch synthesis.

Kanin Energy

Headquartered in Houston, Kanin Energy works with heavy Industry to turn their waste heat into a clean baseload power source. The platform also provides tools such as project development, financing, and operations.

Houston firm invests $150M in leading 'lab on a chip' medical diagnostics co.

fresh funds

Houston-based health technology investment firm Hamershlag Private Capital Management Limited (HPCM) announced a $150.15 million venture investment in Patho Care LLC.

Patho Care is a “lab on a chip” medical diagnostics company known for its noninvasive point-of-care testing platforms, such as its Raman spectroscopy-based platform.

Its digital point-of-care testing devices are programmable, mobile, and reusable and can detect current or future respiratory bacterial or viral infections. The company says the technology is more cost-effective and provides results faster than traditional diagnostic methods.

“Patho Care LLC is a distinguished leader in healthcare diagnostics through the utilization of a novel approach with spectroscopy and this investment aligns with HPCM’s strategy of partnering with high-potential companies in dynamic industries,” L. Mychal Jefferson, Chairman of Hamershlag, said in a news release.

The transaction was structured as an acquisition and recapitalization using newly issued common stock and cash, which will work through a newly formed entity, PathoCare Holdings Inc. The deal will also facilitate the repayment of Patho Care LLC's existing financial obligations and settle Patho Care’s outstanding notes, helping ensure the company’s financial readiness, according to the release.

The investment will help Patho Care LLC improve operational efficiencies, broaden its service offerings and continue to innovate in the diagnostic testing space. The companies hope the collaboration will help “unlock new growth opportunities while maintaining the company’s legacy of excellence in an emerging technology,” according to a news release.

“Our commitment to delivering transformative value through innovative investments underscores our confidence in Patho Care’s vision and capabilities,” Jefferson added.

Houston humanoid robotics startup secures millions in pre-seed funding

my robot

A Houston-based startup developing AI-powered humanoid robots for manufacturers and other businesses has raised more than $10 million in pre-seed funding less than a year after its founding.

Nic Radford, co-founder and CEO of Persona AI, declines to disclose the amount raised. However, he tells InnovationMap that it was an eight-figure total.

While not providing names, Radford says Persona AI’s first outside investors include VC firms, institutions and high-net-worth individuals in the U.S., London and Singapore. One of the high-net-worth investors was among the first employees at SpaceX, Elon Musk’s Brownsville, Texas-based aerospace company, according to Radford.

No Houston investors have participated in the funding round yet. However, Radford says he’s working on bringing aboard one local investor before the round closes.

“Houston’s the perfect city to do a company like this in,” Radford says. “It’s just not the perfect investor climate, but it's the perfect city from a customer aspect.”

Persona AI’s pre-seed funding comes amid a dramatic surge in investment capital chasing AI startups. Global funding for AI-related companies exceeded $100 billion in 2024, up more than 80 percent from the 2023 total, Crunchbase data shows.

Radford and co-founder Jerry Pratt, the startup’s chief technology officer, bootstrapped Persona AI. The third co-founder, Jide Akinyode, serves as Persona AI’s chief operating officer. Radford and Akinyode helped develop NASA’s six-foot-two-inch Valkyrie humanoid robot and both are former employees of Webster-based Nauticus Robotics, a provider of autonomous subsea robots.

Persona AI launched last June in what Radford calls “anti-stealth mode.” The startup is close to announcing its first customer, which does business in the industrial sector. Persona AI expects customers to take delivery of its first robot in 18 to 24 months, Radford says.

Persona AI will operate primarily as a robotics-as-a-service provider, with the company retaining ownership of the lifelike robots and selling the labor that they supply. Radford says the startup’s robots will help alleviate a shortage of skilled labor in sectors like manufacturing.

A report released last year by consulting firm Deloitte and the Manufacturing Institute declared that as many as 1.9 million manufacturing jobs in the U.S. could go unfilled between 2024 and 2033 due to a skills gap and a tight labor market.

Persona AI competes in a market with enormous potential. In November, analysts at Citi Global Insights projected that the global market for humanoid robots could soar to $7 trillion by 2050, with 650 million of the robots tackling all sorts of jobs.

Radford says Personal AI is developing a “rugged” five-foot-eight-inch humanoid robot that’s able to survive tough indoor and outdoor conditions and take on tasks like carting around sheet metal, tending to metal-stamping machines, moving storage bins and handling order fulfillment. He likens his company’s robot prototype to a Ford F-150 pickup truck, compared to the less-sturdy versions produced by robotics competitors, which he calls the Toyota Camry or Volkswagen Beetles of the field.

Radford says he and his team “are building a really compelling startup in one of the hottest markets and one of the greatest cities.” Employees work at Persona AI’s headquarters in Houston or its satellite office in Pensacola, Florida, where Pratt is located.

“We don’t hire anybody that’s not a rock star or superstar,” says Radford, “and I think the city is going to benefit tremendously from our efforts at Persona.”

Radford saw his last company, Nauticus Robotics, from founding to IPO, left the company in January and previously told InnovationMap that he couldn't get the idea of advancing humanoid robotics out of his head. Read more here.
