Houston Exponential closed the first round of funding for its fund of funds with $25 million in commitments from nine companies. The money will go to non-Houston venture capitalists to invest back into Houston startups.

HX Venture Fund's first-round partners include: Insperity, Chevron, Shell, Quanta Services, Westlake Chemical, The Plank Companies, PROS, HEB, and Camden.

Kingwood-based Insperity was the anchor investor, committing to $5 million last October, according to the release. The company also provided an undisclosed amount of resources support the operations of the fund as it launched.

"This is another transformational moment for Houston," says Gina Luna, chair of Houston Exponential, in the release. "From day one at Houston Exponential, we have been executing a plan to accelerate the growth of the ecosystem, including connecting Houston startups with the capital they need to grow their businesses. This is a significant, tangible milestone. Houston's leading companies have stepped up in a big way to make this happen, and this is a clear signal that Houston is committed to success."

Houston-based venture capital firm Mercury Fund's co-founder and managing director, Blair Garrou, chaired the fund's advisory board. He's also a board member for HX.

The fund of funds won't donate to Houston organizations directly, Garrou says in a statement. The fund's organizers had a different approach to growing funds in Houston's startup space.

"The HX Venture Fund will invest in venture capital funds outside of Houston – generating investment and interest in the region while increasing the investable capital available to Houston-based startups," says Garrou. "The HX Venture Fund is built upon a proven model that provides multiple benefits to its investors."

The benefitting venture capital funds haven't yet been named.

HX modeled the fund after the Renaissance Venture Capital Fund in Michigan, from which 10 outside venture capital firms benefitted —Mercury Fund was one of the 10. It was Garrou who led the movement to get Renaissance Fund's CEO and Fund Manager, Chris Rizik, as a part of the HX Venture Fund from the start as a member of the investment committee.

The Michigan fund launched 9 years ago and exceeded all expectations. For ever dollar Rizik and his team invested, $17 came back into the Michigan area, he told the Houston Business Journal. He says Houston has the same potential.

"I've spoken to many cities about Renaissance's fund of funds model and the impact it has had on Michigan," says Rizik in the release. "Houston has leaned into this model and it is impressive what they have been able to accomplish in a short time. It is a testament to the commitment of Houston's business and tech leaders to growing the ecosystem. It's really exciting to see."

In October 2017, Houston Exponential was launched by Mayor Sylvester Turner's Innovation and Technology Task Force in collaboration with the Greater Houston Partnership's Innovation Round Table and the Houston Technology Center. HX's launch included three main goals, according to the release: "make Houston a top 10 innovation ecosystem, generate $2 billion in venture capital annually and create 10,000 new technology jobs a year by 2022."

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.
