Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”

Axiom Space announces new CEO amid strategic leadership change

new leader

Six months after promoting Tejpaul Bhatia from chief revenue officer to CEO, commercial space infrastructure and human spaceflight services provider Axiom Space has replaced him.

On Oct. 15, Houston-based Axiom announced Jonathan Cirtain has succeeded Bhatia as CEO. Bhatia joined Axiom in 2021. Cirtain remains the company’s president, a role he assumed in June, according to his LinkedIn profile.

In a news release, Axiom said Cirtain’s appointment as CEO is a “strategic leadership change” aimed at advancing the company’s development of space infrastructure.

Axiom hired Cirtain as president in June, according to his LinkedIn profile. The company didn’t publicly announce that move.

Kam Ghaffarian, co-founder and executive chairman of Axiom, said Cirtain’s “proven track record of leadership and commitment to excellence align perfectly with our mission of building era-defining space infrastructure that will drive exploration and fuel the global space economy.”

Aside from praising Cirtain, Ghaffarian expressed his “sincere gratitude” for Bhatia’s work at Axiom, including his leadership as CEO during “a significant transition period.”

Bhatia was promoted to CEO in April after helping Axiom gain more than $1 billion in contracts, Space News reported. He succeeded Ghaffarian as CEO. Axiom didn’t indicate whether Bhatia quit or was terminated.

Cirtain, an astrophysicist, was a senior executive at BWX Technologies, a supplier of nuclear components and fuel, for eight years before joining Axiom. Earlier, Cirtain spent nearly nine years in various roles at NASA’s Marshall Space Flight Center in Huntsville, Alabama. He previously co-founded a machine learning company specializing in Earth observation.

“Axiom Space is pioneering the commercialization of low-Earth orbit infrastructure while accelerating advancements in human spaceflight technologies,” Cirtain said. “I look forward to continuing our team’s important work of driving innovation to support expanded access to space and off-planet capabilities that will underpin the future of space exploration.”

Among other projects, Axiom is developing the world’s first commercial space station, creating next-generation spacesuits for astronauts and sending astronauts on low-Earth orbit missions.

Houston Spaceport launches $12M expansion for leading space tech co.

to the moon

Houston will get one step closer to the moon, as the Houston Spaceport at Ellington Airport (EFD) has announced an expansion of the lease for Intuitive Machines, the Houston space tech leader dedicated to furthering lunar exploration.

On July 15, the City of Houston announced passage of Amendment 1, which would add three acres of commercial space for Intuitive Machines at the spaceport and a $12 million infrastructure expansion. Approved by the city council and Mayor John Whitmire, the expansion will include new production, testing and support facilities. The amendment extends the current lease for Intuitive Machines from 20 years to 25 years.

"I want to shout out to Intuitive Machines about everything they’re doing at the Houston Spaceport. It’s exciting to see them expand. We’re starting to reach a critical mass out there — more and more aerospace companies want to be at the Spaceport because that’s where innovation is happening,” said Fred Flinkinger, who represents District E on the Houston City Council. “It’s a great sign of momentum, and we’re proud to have them here in Houston."

Intuitive Machines was the first commercial tenant for the Houston Spaceport when it moved into the facility in August 2016. Founded by Stephen Altemus, Kam Ghaffarian, and Tim Crain in 2013, the company holds three contracts with the National Aeronautics and Space Administration (NASA) to deliver payloads to the lunar surface. In 2023, the company opened its doors in Houston with a 105,572-square-foot Lunar Production and Operations Center that contains research and development labs, clean rooms, mission control centers, and a spacecraft assembly floor.


Intuitive Machines landed Odysseus on the moon in February 2024, the first privately owned soft lunar landing ever and the first soft landing since 1972.

The Houston Spaceport is owned and operated by the City of Houston and Houston Airports, who have an eye of keeping the city a prime name in space exploration. As "Houston" was the first word spoken on the moon when Apollo 11 landed in 1969, lunar exploration in particular has a soft place in the heart of the metropolis formerly known as Space City.

“This agreement reinforces Houston’s leadership in space innovation,” said Jim Szczesniak, director of aviation for Houston Airports. “We’re building infrastructure and supporting the next era of lunar and deep space exploration, right here at Houston Spaceport. This partnership represents the forward-thinking development that fuels job creation and drives long-term economic growth.”

Houston space tech startups share latest updates on lunar missions and more

space update

Houston-based space tech companies Axiom Space and Intuitive Machines recently shared updates on innovative projects and missions, each set to launch by 2027.

Axiom Space

Axiom Space, developer of the world’s first commercial space station and other space infrastructure, is gearing up to launch two orbital data center nodes to low-earth orbit by the end of 2025.

The Axiom Space nodes will lay the foundation for space-based cloud computing. Axiom says orbital data centers provide cloud-enabled data storage and processing, artificial intelligence, and machine learning directly to satellites, constellations, and other spacecraft in Earth’s orbit. This innovation will reduce reliance on earth-based systems, enhance wireless mesh networks and improve real-time operation of space-borne assets, according to Axiom.

Axiom has been working on the development of orbital data centers since 2022. The two nodes going into space in 2025 will be part of Kepler Communications’ 10-satellite data relay network, which is scheduled to launch by the end of this year. Axiom Space and Kepler Communications have been collaborating since 2023.

Kam Ghaffarian, co-founder, executive chairman, and CEO of Axiom, says his company already has deals in place with buyers of space-based cloud computing services. Orbital data centers “are integral to Axiom Space’s vision of era-defining space infrastructure, unlocking transformational capabilities and economic growth,” he says.

Axiom Space says it will be able to buy additional payloads on Kepler’s network to boost capacity for orbital data centers. The two companies will team up to provide network and orbital data center services to various customers.

Intuitive Machines

Meanwhile, Intuitive Machines, a space exploration, infrastructure and services company, has picked SpaceX’s Falcon 9 rocket to launch its fourth delivery mission to the moon. The launch will include two lunar data relay satellites for NASA.

Intuitive Machines says its fourth lunar delivery mission is scheduled for 2027. The mission will comprise six NASA commercial lunar payloads, including a European Space Agency drill set designed to search for water at the moon’s south pole.

“Lunar surface delivery and data relay satellites are central to our strategy to commercialize the moon,” Intuitive Machines CEO Steve Altemus says.

The first of five lunar data relay satellites will be included in the company’s third delivery mission to the moon. The fourth mission, featuring two more satellites, will be followed by two other satellite-delivery missions.

Axiom Space CEO steps down, search begins for replacement

CEO hunting

Houston-based space exploration company Axiom Space is searching for a new CEO.

Co-founder Mike Suffredini stepped down effective August 9 as CEO. He cites unidentified personal reasons for his transition from CEO to company advisor. Suffredini remains a board member of Axiom Space.

Co-founder Kam Ghaffarian, the company’s executive chairman, is serving as interim CEO until Axiom Space taps Suffredini’s permanent successor.

“We are grateful for Mike’s invaluable contributions to human space exploration and the remarkable growth of Axiom Space,” Ghaffarian says in a news release. “He will continue to offer his unique perspective and expertise as we advance our mission.”

Suffredini — who managed NASA’s International Space Station program from 2005 to 2015 — founded Axiom Space in 2016 with Ghaffarian. The company operates missions to the International Space Station, is building the world’s first commercial space station, and is developing commercial infrastructure for the space economy.

At one point, Suffredini also held the title of president. Axiom Space executive Matt Ondler was promoted to that job in 2023.

Suffredini led the company as it reached numerous milestones, such as:

Earlier this month, Axiom Space named NASA veteran Peggy Whitson, a former student and professor at Houston’s Rice University, as commander of their next global crew heading to the International Space Station aboard a private mission. Whitson and her three fellow crew members arrived in Houston on August 6 to train with Axiom Space, NASA, and SpaceX for Axiom Mission 4. The mission is tentatively scheduled for October.

Houston space tech startup raises $350M series C, clinches unicorn status

$1B club

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold. Axiom reports that, according to available data, it's now raised the second-most funding of any private space company in 2023 behind SpaceX.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.

"We are building on the legacy of the International Space Station, leveraging the pillars that were constructed in low-Earth orbit more than two decades ago, to now support a burgeoning global space economy,” he continues.

Axiom, founded in 2016 by Suffredini and Executive Chairman Kam Ghaffarian, is working on the first commercial space station that will replace the International Space Station when NASA retires it in 2031. The first module is expected to launch to the ISS by 2026.

Boryung, which has reportedly invested in Axiom prior to this round, is a firm focused on health care investments. Chairman of the firm, Jay Kim, says Boryung is making investments in technology that supports human space missions and building a space health care system.

“We recognize the depth of human spaceflight knowledge and the level of space station construction and management experience at Axiom Space, as well as the sophistication of the company’s sales and business strategy,” Kim says in the release. “We have a shared vision and ethos and are excited to build opportunity together.”

Naif AlMesned, CEO and managing director of Aljazira Capital, says his investment in Axiom is in accordance with Saudi Vision 2030, a government program launched in 2016 by the Kingdom of Saudi Arabia to increase economic, cultural, and social diversification for the sovereign state.

“We believe in the importance of innovation in various sectors and across various markets," AlMesned says in the release. "In line with the Saudi Vision 2030’s transformative approach, we acknowledge the need for technology toward the advancement of human life. To that end, we are excited to support Axiom Space along its journey of building for beyond.”

In addition to its work on Axiom Station, the company is working on other contracts with NASA, including constructing a new age spacesuit, a long-term NASA contract that's reported to be $1.26 billion. Axiom has also collaborated with NASA on two private astronaut missions — with two more planned for 2024.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

  • 1. Memphis, Tennessee
  • 2. Houston, Texas
  • 3. St. Louis, Missouri
  • 4. San Francisco, California
  • 5. Kansas City, Missouri
  • 6. Albuquerque, New Mexico
  • 7. Oakland, California
  • 8. Nashville, Tennessee
  • 9. Philadelphia, Pennsylvania
  • 10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

  • Fort Worth ranked No. 22
  • Austin ranked No. 26
  • San Antonio ranked No. 54
  • Dallas ranked No. 73

Houston healthtech startup raises $30M to scale surgical healing gel

fresh funding

Houston-based healthtech startup TYBR Health has raised a $30 million Series A round to scale its B3 GEL System, which helps protect tendons from scarring after surgery.

The round was led by Minneapolis-based Vensana Capital and Cleveland-based Mutual Capital Partners, with participation from Denver-based Neovate Capital Partners and existing investors, according to a news release from the company.

TYBR Health said it plans to use the funding to broaden the B3 GEL System's clinical applications, expand commercialization and conduct studies to evaluate its ability to protect tissue and improve healing outcomes.

"Surgeons are exceptionally good at the structural repair, but the biology that follows is what determines how it heals. That part of the equation has gone largely unaddressed ... There's a shift underway across surgical specialties, from focusing almost entirely on the mechanical repair to also weighing the biological conditions that repair needs to succeed," Tim Keane, co-founder and CEO of TYBR Health, said in the news release. "This financing lets us reach more surgeons and generate the clinical evidence to move that shift forward."

As part of the financing round, Greg Banker of Vensana Capital and Liz Todia Zambory of Mutual Capital Partners will join the TYBR board, alongside independent director Aaron Smith.

"TYBR Health is addressing a gap surgeons have lived with for a long time, with a product that fits the way they already work," Zambory, principal at Mutual Capital Partners, added in the release. "We're excited to co-lead this round and support the company's growth."

TYBR was founded in 2020 and originated from the TMCi’s Biodesign fellowship and participated in the TMC's Accelerator for HealthTech. Its B3 GEL System is a flowable extracellular matrix hydrogel designed to protect tendons, ligaments, muscles, and the surrounding soft tissue while they heal from orthopedic surgery. It received FDA 510(k) clearance last June and launched an Australian clinical trial in the fall.

The B3 GEL System has been used in hand, wrist, shoulder, foot and ankle, and sports medicine procedures since it launched, according to the company, and was first used in the clinical setting earlier this year by Dr. Tammam Hanna with Texas Tech University Health Sciences Center.
