Lounging at Margaritaville Lake Resort at Lake Conroe was just made easier by Rivalry Tech, a Houston-based mobile ordering platform company. Rivalry Tech upgraded poolside ordering with its myEATz. According to a news release, customers can now order food and drinks from the 5 o’Clock Somewhere Bar and Lone Palm Bar via a custom QR code system for each lounge chair and table to increase operational efficiency for the Margaritaville Lake Resort staff.

“We wanted to be sure the rollout of the myEATz mobile ordering platform was helpful to the Margaritaville staff, not a hindrance to their existing process. We created custom QR codes and a color coded map to easily identify where the mobile orders are going,” says Charles Willis, COO of Rivalry Tech, in the release.

Rivalry, which provides mobile ordering at numerous sports stadiums and venues with sEATz, expanded into hospitality this year.

“The Rivalry Tech team helped us to seamlessly implement mobile ordering at Margaritaville Lake Resort. They created the marketing materials, established custom QR codes, uploaded mentors and trained our staff onsite. The whole process has been easy and collaborative,” says Amit Sen, director food and beverage for Margaritaville Lake Resort, in the release.

Houston-based venture capital firm Mercury led Phillidelphia-based SaaS company ReturnLogic's $8.5 million series A funding round, which also had participation from Revolution’s Rise of the Rest Fund, White Rose Ventures, and Ben Franklin Technology Partners. The fresh funding will help the company double its workforce, accelerate product development, and expand Application Programming Interface capabilities, according to a news release.

Founded by CEO Peter Sobotta, Return Logic's SaaS platform, which can be plugged into existing e-commerce platforms, helps to enhance management of returns and prevent the challenging financial impacts of returns.

“While retailers have largely mastered forward logistics to get products into customers hands, the returns process remains an under-addressed, resource-draining problem that eats away at brands’ profits,” says Blair Garrou, managing director of Mercury, in a news release. “ReturnLogic is something entirely new to this market and uniquely built on Peter Sobotta’s deep operational experience in reverse logistics and supply chain management.

"While serving in the U.S. Navy, Peter specialized in reverse logistics and gained extensive expertise in ecommerce operations," Garrou continues. "With Peter at the helm, ReturnLogic’s innovative API-first returns solution is well-positioned to tackle the ever-growing operational returns problem facing retailers. We are excited to partner with Peter and his team as they continue to solve this massive problem for online retailers.”

OpenStax, a tech initiative from Rice University that uploads free learning resources, has announced it will publish the 10th edition of an organic chemistry textbook by Cornell University professor emeritus John McMurry.

“This is a watershed moment for OpenStax and the open educational resources (OER) movement,” says Richard Baraniuk, founder and director of OpenStax, in a news release. “This publication will quickly provide a free, openly licensed, high-quality resource to hundreds of thousands of students in the U.S. taking organic chemistry, removing what can be a considerable cost and access barrier.”

Usually a big expense for organic chemistry students, McMurry, with the support of publisher Cengage, made the decision to offer the latest edition online as a tribute to his son, Peter McMurry, who died in 2019 after a long struggle with cystic fibrosis.

“If Peter were still alive, I have no doubt that he would want me to work on this 10th edition with a publisher that made the book free to students,” McMurry says in the release. “To make this possible, I am not receiving any payment for this book, and generous supporters have covered not only the production costs but have also made a donation of $500,000 to the Cystic Fibrosis Foundation to help find a cure for this terrible disease.”

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
