According to Forbes, half of all of the world’s billionaires are less wealthy than they were in 2022. But that’s not the case for most Houston-area billionaires like oil tycoon Jeffery Hildebrand, who was named the richest man in the city.

The 2023 edition of Forbes’ World’s Billionaires List declared Hildebrand’s net worth at $10.2 billion, placing him as the 171st richest person in the world. His fortune is $2.7 billion higher than his 2022 net worth of $7.5 billion, when he ranked No. 316 on the list.

As CultureMap reported, in 2015, Hildebrand made headlines when he gifted each of his 1,381 employees a $100,000 holiday bonus.

Houston’s favorite hospitality mogul and Rockets owner Tilman Fertitta is the city’s second-richest man, with his net worth climbing up to $8.1 billion. He ranked No. 256 on Forbes’ list, substantially higher than his No. 471 rank in 2022 when his net worth was $5.6 billion. Fertitta is surely living life to the fullest after hosting Miami rapper Pitbull at his San Luis Salute celebration earlier this year.

New to the 2023 report is Kamal Ghaffarian, the co-founder and executive chairman of Houston's Axiom Space, with a net worth of $2.1 billion. Though his LinkedIn notes that he is based in Maryland, reports add that he resides in Florida. His Forbes rank is No. 1434.An honorable mention (and billionaire newbie) is Amy Adams Strunk, the controlling owner of the Tennessee Titans and daughter of Houston Oilers owner Bud Adams. She has a residence in Waller (about 40 miles northwest of Houston) and her net worth is $1.7 billion — making her No. 1725 on the list.One name missing from Forbes 2023 report is software entrepreneur Robert Brockman, who passed away last August. Brockman fell from grace after he was charged in the largest tax fraud case in U.S. history in 2020. Forbes listed his 2022 net worth at $4.7 billion. He is survived by his wife, son, and two grandchildren.Elsewhere in Texas, Elon Musk reigns as the richest man in the state and in its capital city of Austin with a net worth of $180 billion. The Tesla and Space-X founder is the second richest person in the world, wedging his way between No. 1 Bernard Arnault of France (overseer of the LVMH empire of 75 fashion and cosmetics brands, including Louis Vuitton and Sephora), with a net worth of $211 billion; and No. 3 Jeff Bezos, the American Amazon founder, worth $114 billion.

Dallas Cowboys owner Jerry Jones'$13.3 billion net worth won him the title of Dallas' richest person, and the 12th richest sports owner on Forbes' "World's Richest Sports Owners 2023." His net worth is up from $10.6 billion last year.

The Fort Worth-based Walmart family heiress Alice Walton earned a spot on Forbes’ list as the third richest woman in the world. Her fortune is pegged at $56.7 billion, down slightly from $65.3 billion last year.

Intuitive Machines to buy satellite maker Lanteris for $800M

space deal

Houston-based aerospace company Intuitive Machines has agreed to buy satellite manufacturer Lanteris Space Systems for $800 million from private equity firm Advent International.

Intuitive Machines co-founder, president and CEO Steve Altemus said the combined revenue of his company and Palo Alto, California-based Lanteris exceeded $850 million as of Sept. 30, and their backlog of orders totaled $920 million.

Until recently, Lanteris operated as Maxar Space Systems. Its origins date back to 1957.

The deal—comprising $450 million in cash and $350 million in Class A shares of Intuitive Machines stock—is expected to close in the first quarter of 2026.

The acquisition “marks the moment Intuitive Machines transitions from a lunar company to a multi-domain space [company], setting the pace for how the industry’s next generation will operate,” Altemus said.

Altemus said the acquisition would enable Intuitive Machines to better compete for Earth orbit, lunar, Mars and deep space projects. Among the opportunities that would open up thanks to the Lanteris deal are the proposed Golden Dome missile defense system and a large lunar lander capable of carrying astronauts, he said.

“The new Intuitive Machines will combine rapid innovation and precision spacecraft production to meet the growing demand for responsive, high-reliability space infrastructure and services,” Altemus said.

Intuitive Machines, founded in 2013, develops lunar landers and provides aerospace services. In 2024, it became the first U.S. company to land a spacecraft on the moon in half a century.

Altemus said Intuitive Machines is already building three satellites for NASA’s near-space network, and it might upsize two more satellites now that it plans to buy Lanteris.

Aside from satellites, Lanteris is developing the power and propulsion element for NASA’s Gateway, a lunar orbiting command module that will support Artemis missions and deep space exploration.


Lanteris was a division of Maxar Technologies, which Advent and minority investor British Columbia Investment Management took private in a 2023 deal valued at $6.4 billion

Anil Shetty, InformAI

Anil Shetty serves as president and chief medical officer for biotech company Ferronova and chief innovation officer for InformAI. He's mentored numerous medical device and digital health companies at seed or Series A, including Pathex, Neurostasis, Vivifi Medical and many others. He mentors through organizations like Capital Factory, TMC Biodesign, UT Venture Mentoring, UTMB Innovation and Rice's Global Medical Innovation program.

"Being a mentor means empowering early-stage innovators to shape, test, and refine their ideas with clarity and purpose," Shetty says. "I’m driven by the opportunity to help them think strategically and pivot early before resources are wasted. At this critical stage, most founders lack the financial means to bring on seasoned experts and often haven’t yet gained real-world exposure. Mentorship allows me to fill that gap, offering guidance that accelerates their learning curve and increases the chances of meaningful, sustainable impact."

Jason Ethier, EnergyTech Nexus

Jason Ethier is the founding partner of EnergyTech Nexus, through which he has mentored numerous startups and Innovation Awards finalists, including Geokiln, Energy AI Solutions, Capwell Services and Corrolytics. He founded Dynamo Micropower in 2011 and served as its president and CEO. He later co-founded Greentown Labs in Massachusetts and helped bring the accelerator to Houston.

"Being a mentor means using my experience to help founders see a clearer path to success. I’ve spent years navigating the ups and downs of building companies, struggling with cash flow, and making all the mistakes; mentoring gives me the chance to share those lessons and show entrepreneurs the shortcuts I wish I’d known earlier," Ethier says. "At Energytech Nexus, that role goes beyond just helping individual founders — it’s about creating a flywheel effect for Houston’s entire innovation ecosystem."

Jeremy Pitts, Activate Houston

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston last year. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Being a mentor to me is very much about supporting the person in whatever they need. Oftentimes that means supporting the business—providing guidance and advice, feedback, introductions, etc," But just as important is recognizing the person and helping them with whatever challenges they are going through ... Sometimes they need a hype man to tell them how awesome they are and that they can go do whatever hard thing they need to do. Sometimes they just need an empathetic listener who can relate to how hard these things are. Being there for the person and supporting them on their journey is key to my mentorship style."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard and chief information officer at Empact IT, which he also owns. He mentors through Founder Fridays Houston Group, Software Day by Mercury Fund, SUPERGirls SHINE Foundation, Cup of Joey and at the Ion. He's worked with founders of FlowCare, STEAM OnDemand, Lokum and many other early stage startups.

"Being a mentor to me means unleashing an individual’s 10x—their purpose, their ikigai (a Japanese concept that speaks to a person’s reason for being)," Alapat says. "Mentoring founders in the Houston community of early stage, high-growth startups is an honor for me. I get to live vicariously through a founder’s vision of the future. Once they show me that compelling vision, I’m drawn to bring the future forward with them so the vision becomes reality with a sense of urgency."

Neal Dikeman, Energy Transition Ventures

Neal Dikeman serves as partner at early stage venture fund Energy Transition Ventures, executive in residence at Greentown Labs, and offices in and supports Rice Nexus at the Ion. He mentors startups, like Geokiln, personally. He also mentored Helix Earth through Greentown Labs. The company went on to win in the Smart Cities, Transportation & Sustainability contest at SXSW earlier this year. Dikeman has helped launch several successful startups himself, most recently serving on the board of directors for Resilient Power Systems, which was acquired by Eaton Corp for $150 million.

"Founders have to find their own path, and most founders need a safe space where they can discuss hard truths outside of being 'on' in sales mode with their team or board or investors, to let them be able to work on their business, not just in it," Dikeman says.

Nisha Desai, Intention

Nisha Desai serves as CEO of investment firm Intention and mentors through Greentown Labs, TEX-E, Open Minds, the Rice Alliance Clean Energy Accelerator, Avatar Innovations and The Greenhouse. She currently works with founders from Solidec, Deep Anchor Solutions, CLS Wind and several other local startups, several of which have been nominated for Innovation Awards this year. She's served a board member for Greentown Labs since 2021.

"When I first started mentoring, I viewed my role as someone who was supposed to prevent the founder from making bad decisions. Now, I see my role as a mentor as enabling the founder to develop their own decision-making capability," Desai says. "Sometimes that means giving them the space to make decisions that might be good, that might be bad, but that they can be accountable for. At the end of the day, being a mentor is like being granted a place on the founder's leadership development journey, and it's a privilege I'm grateful for."

Rice, Houston Methodist developing soft 'sleep cap' for brain health research

Researchers and scientists at Rice University and Houston Methodist are developing a “sleep cap” that aims to protect the brain against dementia and other similar diseases by measuring and improving deep sleep.

The project is a collaboration between Rice University engineering professors Daniel Preston, Vanessa Sanchez and Behnaam Aazhang; and Houston Methodist neurologist Dr. Timea Hodics and Dr. Gavin Britz, director of the Houston Methodist Neurological Institute and chairman of the Department of Neurosurgery.

According to Rice, deep sleep is essential for clearing waste products from the brain and nightly “cleaning cycles” help remove toxic proteins. These toxic proteins, like amyloids, can accumulate during the day and are linked to Alzheimer’s disease and other neurological issues.

Aazhang, director of the Rice Neuroengineering Initiative, and his team are building a system that not only tracks the brain’s clearing process but can also stimulate it, improving natural mechanisms that protect against neurodegeneration.

Earlier proof-of-concept versions of the caps successfully demonstrated the promise of this approach; however, they were rigid and uncomfortable for sleep.

Preston and Sanchez will work to transform the design of the cap into a soft, lightweight, textile-based version to make sleep easier, while also allowing the caps to be customizable and tailored for each patient.

“One of the areas of expertise we have here at Rice is designing wearable devices from soft and flexible materials,” Preston, an assistant professor of mechanical engineering, said in a news release. “We’ve already shown this concept works in rigid device prototypes. Now we’re building a soft, breathable cap that people can comfortably wear while they sleep.”

Additionally, the research team is pursuing ways to adapt their technology to measure neuroinflammation and stimulate the brain’s natural plasticity. Neuroinflammation, or swelling in the brain, can be caused by injury, stroke, disease or lifestyle factors and is increasingly recognized as a driver of neurodegeneration, according to Rice.

“Our brain has an incredible ability to rewire itself,” Aazhang added in the release. “If we can harness that through technology, we can open new doors for treating not just dementia but also traumatic brain injury, stroke, Parkinson’s disease and more.”

The project represents Rice’s broader commitment to brain health research and its support for the Dementia Prevention Research Institute of Texas (DPRIT), which passed voter approval last week. The university also recently launched its Rice Brain Institute.

As part of the project, Houston Methodist will provide access to clinicians and patients for early trials, which include studies on patients who have suffered traumatic brain injury and stroke.

“We have entered an era in neuroscience that will result in transformational cures in diseases of the brain and spinal cord,” Britz said in the release. “DPRIT could make Texas the hub of these discoveries.”
