A travel booking technology company that's looking to alleviate some of the stresses of finding and making hotel reservations has raised additional seed funding.

Houston-based Pinktada has raised additional funding to the tune of $975,000. Ireland-based Selenean Capital contributed to the seed funding round, joining the company's previous investor True Global Ventures 4 Plus, which has invested $2 million to date. According to Crunchbase data, the latest investment brings the company's total to $3.9 million.

“Selenean Capital’s approach to partnership is identifying real world future needs and then working relentlessly to achieve those goals," says Davin Browne, Selenean’s CEO, in a news release. "Pinktada encapsulates this perfectly with a transformational approach to the hotel booking model built around a brilliant team. We look forward to the partnership and journey with them."

Founded in 2020, Pinktada launched its booking platform earlier this year. The technology — backed by NFT encryption — allows users to sell or trade existing lodging reservations. As many hotels and third-party booking sites offer cheaper non-refundable booking options, Pinktada gives travelers a secure alternative if their plans change. The company's hotel partners can benefit from the transactions, too, per the company's statement.

“We are thrilled with the market validation we are receiving,” says Mark J. Gordon, chief hospitality officer, in the release. “We launched in May with properties in Hawaii and the Dominican Republic, have since added exquisite hotels in Mexico, New York, Miami and San Francisco, and have another 18 in the process of being on-boarded. More important though is the caliber of our partners, which are leading hotel industry names.”

According to the company, membership grew 20 percent in August and 40 percent in September as the platform added new hotel partners.

“We could not be more excited about our prospects," says Lyon Hardgrave, Pinktada’s CEO, in the release. “This investment reflects the significant progress we have made this year. It will allow us to accelerate the onboarding of new hotels, dial up marketing efforts, and continue to evolve our technology to embrace other large opportunities.”

Hospitality startup adds a new luxe approach to Houston's apartment rental market

City living

In 2018, Houston set a new tourism record with 22.3 million visitors to the city. That same year, Sébastien Long was finishing his Cambridge thesis on home-sharing companies like Airbnb and falling in love with a classmate. When the couple moved to Houston after graduation, Long brought his ideas with him, and that's how Lodgeur was born.

Lodgeur works as an upscale home-sharing startup that offers luxury apartments in midtown and downtown Houston for nightly rent. It doesn't replace Airbnb; customers can browse through and book the properties through the familiar website. Guests can also book short or extended stays directly with Lodgeur's website.

In short, Long's research found that most Airbnb's have high guest experience ratings, but those user reviews don't work to inspire the 90 percent of Americans who haven't used a homestay service. Those people have worries — mostly about what to expect, about safety, and about having to interact with homeowners. Long believes he can calm those fears by building a trusted brand that customers recognize on Airbnb, and Houston turned out to be the perfect place to do that: his main inspiration, Conrad Hilton, did the same with hotels over the last century.

"Houston has been a city that's been overlooked. Most companies didn't come here first," Long says. "Actually, people are coming to Houston every week of the year, prices don't fluctuate too much, and you're probably going to be running at a high occupancy every week of the year."

So Long drove around the city, looking for apartment buildings he liked and hoped his guests would, too. Having grown up working at the campground-turned-resort started by his parents in the French Mediterranean, he had an eye for what tourists found attractive — buildings with character, high-end aesthetics and clean designs like a hotel, but with modern kitchen appliances and more space.

"We're roughly split between leisure guests and business travelers," Long says. "They want to feel like they're staying in a home away from home."

Getting that experience is about the same price as a hotel. The properties range from $90 per night to a $200 apartment with 50 feet of floor-to-ceiling windows overlooking downtown. The apartments have not just attracted outside visitors; people have come from around Houston to stay during home renovations or when their houses have flooded, Long says.

The first guests arrived in mid-April. Long wanted to open by managing just a few properties, to make sure the company could ensure great guest experiences.

Last week, he hired his first full-time employee — an ex-marine who graduated from the University of Houston's Conrad Hilton College of Hospitality — and has contracted a marketing agency to turn up Lodgeur's social media presence. For now, Lodgeur relies on a freelance interior designer to fashion the apartments and a local housekeeping company to keep them clean.

Long — who is a Station Houston and WeWork Labs member — says he is looking to expand, but he wants to do so organically: Many of the owners of properties he's already renting own other apartment complexes, and he plans to work with them to move Lodgeur out of inner Houston, and then to other cities. Lodgeur isn't raising funds yet, but Long says he'll be looking for investors this summer.

Recently, Long stayed at Hilton in Austin — his first time at a hotel since launching Lodgeur. He booked a room with a king-sized bed, but it felt small. Business requires him to carry a tape measure, so he measured the mattress: it was six inches smaller than the mattresses Lodgeur uses. He laughed, thinking of how much more comfortable guests would be in an apartment with bigger beds and more space.

"I don't know how people would go back (to hotels)," he says.

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
