It's no secret that Austin and San Antonio are becoming some of the biggest cities in Texas, and that together, they just might rival the likes of Houston and Dallas-Fort Worth one day.

A new documentary called San Antonio-Austin: The Emerging Mega-Metro takes a deep dive into the booming 80-mile region between the Central Texas cities

Produced by KLRN, San Antonio's local PBS station, the program centers on the region's growth and the challenges that arise with such rapid expansion, such as water scarcity, environmental impacts, and increasingly common transportation and traffic woes.

They're issues that Houston residents know well, as the city's population continues to explode at a staggering rate.

"We know the area between San Antonio and Austin is growing at a tremendously rapid pace, but what is really happening is the development of a mega-metro that will be one of the biggest economic powerhouses in the world," says Shari St. Clair, the documentary's executive producer, in a release.

“We delve into the questions that need to be asked right now — how do we retain quality of life as we grow? How do we build a sustainable workforce?" St. Clair continues. "And, can San Antonio and Austin truly join forces and work together to make the most of this incredible opportunity?"

The hour-long documentary is hosted by former San Antonio mayor Henry Cisneros, who also authored The Texas Triangle: An Emerging Power in the Global Economy. The special highlights several prominent Central Texas leaders, including interviews with Austin Mayor Kirk Watson, San Antonio Mayor Ron Nirenburg, U.S. Congressman Greg Casar, and more.

As Texas is also a state of committed sports fans, the idea of a mega-metro between Austin and San Antonio is additionally explored through a sports lens. The documentary interviewed legends like Nolan Ryan, Sean Elliot, and Spurs Chairman Peter J. Holt.

Houston-Dallas high-speed bullet train gets back on the rails thanks to potential Amtrak partnership

In the latest chapter in the saga of the high-speed bullet train between Houston and Dallas, Amtrak is now involved.

According to a press release, Texas Central Partners and Amtrak are exploring a partnership to work together on the proposed Dallas-Houston high-speed rail project that's been under consideration for more than a decade.

Amtrak has cooperated with Texas Central on various initiatives since 2016 and the two entities are now evaluating a potential partnership to determine the line's viability.

“If we are going to add more high-speed rail to this country, the Dallas to Houston Corridor is a compelling proposition and offers great potential,” says Amtrak senior VP of High-Speed Rail Development Programs Andy Byford. “We believe many of the country's biggest and fastest-growing metropolitan areas, like Houston and Dallas, deserve more high quality high-speed, intercity rail service, and we are proud to bring our experience to evaluate this potential project and explore opportunities with Texas Central so the state can meet its full transportation needs.”

The route being proposed would span approximately 240 miles, going at 250 mph, resulting in a trip that would take less than 90 minutes between the two cities.

Texas Central has been working towards getting a train rolling since 2013, including lining up a potential builder in 2021. But the project has had pushback from Texas politicians and landowners along the route; a lawsuit against the project was filed by six rural counties in 2021, and the Texas Legislature passed a law prohibiting the state from spending any funds on the project.

Facing a seeming dead end, Texas Central CEO Carlos Aguilar and its board members resigned in June 2022; Michael Bui, a consultant, has been serving as CEO since then.

Texas Central and Amtrak have submitted applications to several federal programs in connection with further study and design work, including the Consolidated Rail Infrastructure Safety and Improvements (CRISI) grant program, the Corridor Identification and Development program, and the Federal-State Partnership for Intercity Passenger Rail (FSP-National) grant program.

Amtrak previously entered into an agreement with Texas Central to provide through-ticketing using the Amtrak reservation system and other support services for the planned high-speed rail line.

"This high-speed train, using advanced, proven Shinkansen technology, has the opportunity to revolutionize rail travel in the southern U.S., and we believe Amtrak could be the perfect partner to help us achieve that,” says Bui in a statement.

Despite its detractors, the project is forecast to provide social, environmental, employment and economic benefits including reducing greenhouse gas emissions by more than 100,000 tons per year, saving 65 million gallons of fuel and removing 12,500 cars per day from I-45.

The release from Amtrak has statements from both Dallas Mayor Eric L. Johnson and Houston Mayor Sylvester Turner, who calls the collaboration between Texas Central and Amtrak "an important milestone for the City of Houston and this project."

Byford joined Amtrak in April 2023 to begin developing a team focused on high-speed opportunities throughout the U.S. In his newly created role, he will develop and lead the execution of Amtrak’s long-term strategy for high-speed rail throughout the country, including the extension of the Crescent from Mississippi through Louisiana and Texas; Kansas DOT’s Heartland Flyer Extension Corridor Identification and Development (Corridor ID) connecting Wichita to Oklahoma and Texas, and TxDOT’s applications for the Texas Triangle (Houston — Dallas – Fort Worth – San Antonio) routes.

Houston startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”

Money Moves

Houston billionaire Tilman Fertitta may currently be serving as America’s ambassador to Italy, but his company is as busy as ever. Fresh off its move to revive the Houston Comets WNBA franchise, his company, Fertitta Entertainment, has announced a $17.6 billion deal to acquire Caesars Entertainment, Inc.

Speculation about the deal has been circulating since at least March, according to various media reports. The deal combines Fertitta’s well-known Golden Nugget casino brand with all of the properties in the Caesars’ portfolio, including Las Vegas hotels Caesars Palace, Harrah's, Paris Las Vegas, Planet Hollywood, Horseshoe, The LINQ Hotel, Flamingo, and The Cromwell.

Overall, the combined company will include 60 domestic casino resorts and gaming facilities; online gaming including sports betting, iCasino, and Caesar’s online poker platform; retail sports betting at over 200 third-party locations through the William Hill brand; and over 550 Fertitta Entertainment outlets, including more than 450 Landry's full-service restaurants across America. The companies will combine their loyalty programs, Caesars Rewards, Golden Nugget's 24 Karat Select Club, and Landry's Select Club.

The terms will see Caesars’ shareholders receive $31 per share. Fertitta Entertainment will also acquire approximately $11.9 billion of Caesars' outstanding debt.

The transaction will be financed through a combination of equity contributed by Fertitta Entertainment, assumed Caesars' debt, and new committed debt financing arranged by a group consisting of 10 banks. It is subject to approval by Caesars’ shareholders and government regulators.

Fertitta Entertainment is the Houston-based company behind a diverse array of hospitality businesses, including The Golden Nugget, The Post Oak Hotel, River Oaks District, the Kemah Boardwalk, and Houston’s Downtown Aquarium.

It also operates a number of prominent restaurant brands, including Mastro's Restaurants, Del Frisco's Double Eagle Steakhouse, Morton's The Steakhouse, The Palm, McCormick & Schmick's, Landry's Seafood House, The Oceanaire Seafood Room, and Saltgrass Steak House.
