Startups take home cash prizes at inaugural Houston accelerator demo day

ion smart cities

The Ion Smart Cities Accelerator wrapped up the first phase of its inaugural program with a demo day this week as the startups move onto the pilot phase.

Over the past three months, the 10 selected startups have been working with mentors and the Station Houston resources to hone their companies within the program's new dedicated space, which includes a prototyping lab. At the demo day, which represents the conclusion of the first part of the Intel- and Microsoft-backed program, the startups presented their companies, what they've accomplished, and where they are headed.

Two companies received $5,000 checks from sponsors. GoKid, a carpooling optimization tool, received a prize from Brex, a credit card for startups. The other big winner was Aatonomy, a self-driving communities technology, which was awarded by Gulf States Toyota.

The second leg of the journey begins in January with pilot programs for the next six months. According to Christine Galib, director of Ion Smart Cities Accelerator, the companies have 15 pilots in the Houston area that hope to positively affect the lives of Houstonians.

"Our startups' technology focuses on connecting people. And this is what makes Houston truly the smartest city in America," says Galib. "To truly be the smartest city in America, we must continue to focus on how we connect people, and why we connect people, as well as to provide the processes and partnerships for these connections — not only to occur by chance, but also to be sustainable."

Gabriella Rowe, executive director of The Ion, echoed the importance people had on the smart cities equation.

"The great success that this accelerator has experienced over the last three months has really been because of people," she says.

Among those people who received a special shoutout from Rowe were the program's inaugural set of mentors. Several of these mentors introduced each of the startups as they presented.

"All of you opened your calendars, your time, and your wisdom to help these startups, but also to help our city," Rowe says to the crowd, which included the program mentors. "And to express a universal desire to make Houston the best possible city it can be, accessible to all Houstonians in every way as we grow to be that innovation economy and city of the future."

Houston leads Texas with 7 new National Academy of Inventors senior members

top honor

The University of Houston is now home to seven new senior members of the National Academy of Inventors.

The distinction honors active faculty, scientists and administrators from NAI member institutions that have demonstrated innovation and produced technologies that have “brought, or aspire to bring, real impact on the welfare of society,” according to the NAI. The members have also succeeded in patents, licensing and commercialization, and educating and mentoring.

According to UH, its seven new members represent the largest group from any single Texas institution this year, bringing the university's total senior member count to 46.

UH faculty also represented three of Houston's four new senior members in 2025. Six Houstonians were also named to the NIA's class of fellows late last year.

“This recognition affirms what we see every day at the University of Houston—bold, collaborative innovation focused on improving lives," Ramanan Krishnamoorti, vice president of energy at UH, said in a news release. "Having seven faculty members named Senior Members reflects our momentum and a culture where discovery moves beyond the lab into solutions that strengthen communities and drive economic growth.”

UH’s new senior members include:

Texas takes the No. 1 spot on new energy resilience report

Ranking It

A new report by mineral group Texas Royalty Brokers ranks Texas as the No. 1 most energy-resilient state.

The study focused on four main sources of electricity in hydroelectric dams, natural gas plants, nuclear reactors and petroleum facilities. Each state was given an Energy Resilience Score based on size and diversity of its power infrastructure, energy production and affordability for residents.

Texas earned a score of 71.3 on the report, outpacing much of the rest of the country. Pennsylvania came in at No. 2 with a score of 55.8, followed by New York (49.1) and California (48.4).

According to the report, Texas produces 11.7 percent of the country’s total energy, made possible by the state’s 141,000-megawatt power infrastructure—the largest in America.

Other key stats in the report for Texas included:

  • Per-capita consumption: 165,300 kWh per year
  • Per-capita expenditures: $5,130 annually
  • Total summer capacity: 141,200 megawatts

Despite recent failures in the ERCOT grid, including the 2021 power grid failure during Winter Storm Uri and continued power outages with climate events like 2024’s Hurricane Beryl that left2.7 million without power, Texas still was able to land No. 1 on an energy resilience list. Texas has had the most weather-related power outages in the country in recent years, with 210 events from 2000 to 2023, according to an analysis by the nonprofit Climate Central. It's also the only state in the lower 48 with no major connections to neighboring states' power grids.

Still, the report argues that “(Texas’ infrastructure) is enough to provide energy to 140 million homes. In total, Texas operates 732 power facilities with over 3,000 generators spread across the state, so a single failure can’t knock out the entire grid here.”

The report acknowledges that a potential problem for Texas will be meeting the demands of AI data centers. Eric Winegar, managing partner at Texas Royalty Brokers, warns that these projects consume large amounts of energy and water.

According to another Texas Royalty Brokers report, Texas has 17 GPU cluster sites across the state, which is more than any other region in the United States. GPUs are specialized chips that run AI models and perform calculations.

"Energy resilience is especially important in the age of AI. The data centers that these technologies use are popping up across America, and they consume huge amounts of electricity. Some estimates even suggest that AI could account for 8% of total U.S. power consumption by 2030,” Winegar commented in the report. “We see that Texas is attracting most of these new facilities because it already has the infrastructure to support them. But we think the state needs to keep expanding capacity to meet growing demand."
