Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Texas lands top 10 spot in new future of tech study

report

Texas is among the top 10 states making the biggest investments in digital innovation, according to a new study.

The study, conducted by web-hosting company Hostinger, puts Texas in eighth place among the states when it comes to these key metrics:

  • Financial impact of the digital economy
  • Amount of venture capital and grants received by digital startups
  • Number of government-run tech hubs
  • Presence of top-rated business incubators

“To many, the Texas story is one of oil magnates and real estate tycoons. But in recent decades, the state has emerged as an innovation and high-tech hub,” according to a report from the Federal Reserve Bank of Dallas.

On a scale of 1 to 100, Texas received a score of 79. California nabbed the top spot with a score of 100. Appearing behind California and ahead of Texas in the ranking are:

  • No. 2: New York
  • No. 3: Washington
  • No. 4: Illinois
  • No. 5: Massachusetts
  • No. 6: Missouri
  • No. 7: Wisconsin

In terms of ranking factors, Texas benefited the most from landing at No. 2 among the states for its impact on the digital economy. The study pegged Texas’ digital economic impact at $141.7 billion, well below California’s impact of $492.8 billion.

Hostinger relied primarily on government data on 31 states to come up with the ranking. “The research provides a detailed ranking based on a composite score that reflects each state's overall investment and capacity for digital innovation,” the company says.

More than 30,000 businesses in Texas participate in the digital economy, according to the Computer & Communications Industry Association (CCIA). Those businesses employ more than 633,000 people and account for over six percent of the state’s GDP, a key measure of economic strength.

“As technology companies face increasing scrutiny through state and national legislation and litigation, it’s crucial to recognize the significant positive impacts of the digital economy that resonate across the United States,” says the CCIA.

new bling

Last month, a global organization honored innovation leaders in life sciences, and the Texas Medical Center was among the recipients of the prestigious awards program.

The 18th annual Prix Galien Awards Gala awarded TMC Innovation with the win in the "Incubators, Accelerators and Equity" category. The Galien Foundation created the awards program in 1970 in honor of Galien, the father of medical science and modern pharmacology. Alongside TMC, the other winners represented biotech, digital health, startups, and more.

"We are super proud of this distinction," Tom Luby, director of TMC Innovation says at Envision 2024 last month, crediting the TMCi team and TMC leadership for the award. "We lean on a lot of advisers and experts — people who volunteer their time to work with startups. Without (them), we would not have been successful."

Luby explains that a Prix Galien Award holds a Nobel Prize level of significance for the community.

TMCi was named a finalist in August, and competed against programs from Cedars-Sinai, Mayo Foundation for Medical Education and Research, TechConnect, and more.

"The Awards Committee is honored to witness the exceptional dedication and creativity of our nominees as they turn visionary ideas into transformative solutions for patients worldwide," says Michael Rosenblatt, chair of the Prix Galien USA Awards Committee, in a news release. "Their unwavering commitment to advancing patient care is truly commendable, and we are honored to celebrate their outstanding contributions to global health."

The award is displayed at TMC Innovation's office, located in the medical center at 2450 Holcombe Blvd.

Houston initiative selected for DOE program developing hubs for clean energy innovation

seeing green

Houston has been selected as one of the hubs backed by a new program from the United States Department of Energy that's developing communities for clean energy innovation.

The DOE's Office of Technology Transitions announced the the first phase of winners of the Energy Program for Innovation Clusters, or EPIC, Round 3. The local initiative is one of 23 incubators and accelerators that was awarded $150,000 to support programming for energy startups and entrepreneurs.

The Houston-based participant is called "Texas Innovates: Carbon and Hydrogen Innovation and Learning Incubator," or CHILI, and it's a program meant to feed startups into the DOE recognized HyVelocity program and other regional decarbonization efforts.

EPIC was launched to drive innovation at a local level and to inspire commercial success of energy startups. It's the third year of the competition that wraps up with a winning participant negotiating a three-year cooperative agreement with OTT worth up to $1 million.

“Incubators and Accelerators are uniquely positioned to provide startups things they can't get anywhere else -- mentorship, technology validation, and other critical business development support," DOE Chief Commercialization Officer and Director of OTT Vanessa Z. Chan says in a news release. “The EPIC program allows us to provide consistent funding to organizations who are developing robust programming, resources, and support for innovative energy startups and entrepreneurs.”

CHILI, the only participant in Texas, now moves on to the second phase of the competition, where they will design a project continuation plan and programming for the next seven months to be submitted in September.

Phase 2 also includes two national pitch competitions with a total of $165,000 in cash prizes up for grabs for startups. The first EPIC pitch event for 2024 will be in June at the 2024 Small Business Forum & Expo in Minneapolis, Minnesota.

Last fall, the DOE selected the Gulf Coast's project, HyVelocity Hydrogen Hub, as one of the seven regions to receive a part of the $7 billion in Bipartisan Infrastructure Law. The hub was announced to receive up to $1.2 billion — the most any hub will get.

Tech startups are leaving Silicon Valley in droves — and some are finding benefits in heading back to school. Miguel Tovar/University of Houston

Siliconned: Leaving Silicon Valley for universities

Houston Voices

Silicon Valley has been a tech startup paradise for decades. It has been described as the modern day Florence in the Renaissance. Tech gods from Apple and Google to Facebook and Twitter were born here. We can credit Silicon Valley as the birthplace for such world-changing innovations like smartphones, microprocessor chips, Tesla automation, and WIFI-enabled teapots.

Okay, so maybe that last one isn't changing the world, but it was created in the Valley and it's changed my life, for whatever that's worth. If Silicon Valley were a country, it would have the 19th-biggest economy on the planet. There's no doubt it is an engineer's dream. A techie's haven. A capitalist's utopia. A beacon of the modern world.

Or at least, it used to be.

Now leaving the Bay Area

There is an exodus in Silicon Valley. It's been happening for about three years. For instance, according to a 2018 poll conducted by the Bay Area Council, 46 percent of survey takers admit they plan to leave the Bay Area in the next year. Couple that with the fact that Silicon Valley investors have allocated 66 percent of their funds into startups outside of Silicon Valley, compared with 50 percent just six years ago, and you have a recipe for a great exodus to other markets around the country.

Now, just for kicks, add to all of this that the Kauffman Foundation's research has pegged Miami-Fort Lauderdale as the number one city in America for startup activity. Where does Silicon Valley's Bay Area, formerly the world's preeminent hub for tech startups, rank? Fourteenth. How the mighty have fallen.

So, to what exactly can this mass egress be attributed?

Insufficient funds

The biggest reason is cost.

The cost of living in the Bay Area is one of the steepest on the planet. Startups in the Valley pay four times what they would in any other city in the country. In fact, just last year the California Association of Realtors reported that a typical family in San Francisco has to make over $300,000 a year in order to afford a median-priced house tagged at just over a million dollars. That includes a 20 percent down payment and an $8,000 monthly payment. Because most of the startups in Silicon Valley are in their infancies, the engineers, programmers, and non-technical employees don't get compensated enough to afford such a living. As a result, they are leaving the Bay Area in droves for places where the cost of living is manageable.

One location that tech startup entrepreneurs are flocking to is the university. Universities are also retaining tech wunderkinds on campus to blossom their startups, rather than seeing them leave for the microprocessor motherland known as Silicon Valley.

Now entering university life

One of the biggest reasons universities have become hotbeds for tech startups is that campuses provide a means for people with multidisciplinary backgrounds to intermingle within the same space. A chemical engineering student with a great idea might meet an MBA during a startup launch party. Together they can build and market the second iteration of "Secret Stuff" from Space Jam, or whatever that student has in mind.

The point is that universities position aspiring entrepreneurs to network with the right people for building their company from the ground up. Even the Innovation Leadership Forum attests that innovation is born when different ways of thinking clash. That is precisely what happens on campuses every day.

Furthermore, college students also have more room to take risks. Most aspiring entrepreneurs in college between 18 and 25 are not married, do not have kids, mortgages, or any other major financial responsibilities. This allows them to have the luxury of leeway when it comes to experimenting and trial and error.

The ecosystem of innovation

In essence, academic incubators are courting tech entrepreneurs because universities offer an ecosystem designed to support and grow startups from conception to commercialization. This ecosystem includes a space where researchers, faculty, and students of all disciplines interact and form working relationships. In many cases, it also includes university owned equipment and laboratories for use by startup researchers.

There is, of course, incentive for universities to concentrate so many resources to building incubators and luring startup entrepreneurs. There is an inherent sense of responsibility that universities have to create an academic climate that encourages students to explore new ideas. A sense of responsibility that encourages them to take more risks; to be fearless in their quest to use their intellect to enrich lives; to dream.

Moreover, university incubators also position schools as progressive institutions. Such positioning attracts elite researchers and enhances a university's reputation. Further, these incubators forge a bridge that links industry and academia in a way that Silicon Valley does not. That's because with academic incubators, startups are a stone's throw away from a place teeming with researchers, scientists, hungry students, and aspiring entrepreneurs: the university campus.

Consequently, it is no wonder that tech startups are leaving Silicon Valley for universities. It's also no surprise that students who have graduated are staying with their university's incubators to develop their companies. There, they have a place that cultivates innovation, encourages risk-taking, and is set up specifically to help them bring their tech to the world. In short, the university has become a hub set up to be conducive to thriving tech startups. And tech entrepreneurs have noticed.

Here's the income it takes to live comfortably in Houston in 2026

Money Talk

2026 report analyzing how much it costs to live "in sustainable comfort" in the biggest U.S. cities has found Houston residents have the 11th lowest salary requirement to live a comfortable life in 2026.

SmartAsset's annual report found single adult residents in Houston need to make $89,981 a year to qualify as "financially stable." Compared to last year, single Houstonians needed to make $83 more to live comfortably in the city.

Families with two working parents and two children need to make a household income of $204,672 to have a financially stable life in Houston, the report found. That's almost $2,000 less than what families needed to make last year.

To determine the rankings, SmartAsset's analysts examined 100 of the largest U.S. cities and used the latest cost of living data – such as the costs for housing, food, transportation, and income taxes where applicable – from the MIT Living Wage Calculator for childless individuals and for two working adults with two children.

For the purpose of the study, the 50/30/20 budgeting strategy was used to determine "comfortable lifestyle" costs for both individuals and families: 50 percent of income to cover needs and living expenses, 30 percent for "wants," and 20 percent for savings or paying down debt.

Here's breakdown of a Houston resident's comfortable lifestyle based on SmartAsset's findings:

  • $44,991 dedicated to needs and living expenses
  • $26,994 dedicated to wants
  • $17,996 dedicated to savings or debt repayment

This is SmartAsset's interpretation of a comfortable lifestyle for families of four:

  • $102,336 dedicated to needs and living expenses
  • $61,402 dedicated to wants
  • $40,934 dedicated to savings or debt repayment
SmartAsset said single individuals and families should compare the fluctuating local cost of living and their long-term goals to fully "understand the context" of their respective household incomes. But it's worth pointing out that a financially stable life in Houston isn't quite attainable for many residents: The city had a median household income of $64,361 in 2024, according to the U.S. Census Bureau.

Comfortable salaries in other Texas cities

Elsewhere in Texas, the report found that families in the Dallas-Fort Worth suburbs Frisco and McKinney "are closest to a comfortable salary."

"In Frisco, the median household earns $145,444 – substantially higher than the national median of $83,730," the report's author wrote. "This figure also accounts for 63.1 percent of the $230,464 income a family of four in Frisco needs to live comfortably. In McKinney, TX, the $124,177 median household income accounts for 53.9 percent of the $230,464 needed."

Both cities also tied with Plano for the 29th highest salary needed nationally to live comfortably in 2026. Single adults living in these cities need to make $109,242 a year to live a financially stable life this year.


On the opposite end, San Antonio has the lowest salaries needed to live comfortably in the U.S. Single adults only need to make $83,242 a year, and $192,608 for families of four.

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization
