National hardtech-focused organization Activate has named its 2025 cohort of scientists, which includes new members to Activate Houston.

The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Collectively, the 2025 Activate Fellowship consists of 47 scientists and engineers from nine U.S. states.

This year's cohort comprises subject matter experts across various fields, including quantum, robotics, biology, agriculture, energy and direct air capture.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. The fellows receive a living stipend, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

“Science entrepreneurship is the origin story of tomorrow’s industries,” Cyrus Wadia, CEO of Activate, said in an announcement. “The U.S. has long been a world center for science leadership and technological advancement. When it comes to solving the world’s biggest challenges, hard-tech innovation is how we unlock the best solutions. From infrastructure to energy to agriculture, these Activate Fellows are the bold thinkers who are building the next generation of science-focused companies to lead us into the future.”

The Houston fellows selected for the 2025 class include:

  • Jonathan Bessette, founder and CEO of KIRA, which uses its adaptive electrodialysis system to treat diverse water sources and reduce CO2 emissions
  • Victoria Coll Araoz, co-founder and chief science officer of Florida-based SEMION, an agricultural technology company developing pest control strategies by restoring crops' natural defenses
  • Eugene Chung, co-founder and CEO of Lift Biolabs, a biomanufacturing company developing low-cost, nanobubble-based purification reagents. Chung is completing his Ph.D. in bioengineering at Rice University.
  • Isaac Ju, co-founder of EarthFlow AI, which has developed an AI-powered platform for subsurface modeling, enabling the rapid scaling of carbon storage, geothermal energy and lithium extraction
  • Junho Lee, principal geotechnical engineer of Houston-based Deep Anchor Solutions, a startup developing innovative anchoring systems for floating renewables and offshore infrastructure
  • Sotiria (Iria) Mostrou, principal inventor at Houston-based Biosimo Chemicals, a chemical engineering startup that develops and operates processes to produce bio-based platform chemicals
  • Becca Segel, CEO and founder of Pittsburgh-based FlowCellutions, which prevents power outages for critical infrastructure such as hospitals, data centers and the grid through predictive battery diagnostics
  • Joshua Yang, CEO and co‑founder of Cambridge, Massachusetts-based Brightlight Photonics, which develops chip-scale titanium: sapphire lasers to bring cost-effective, lab-grade performance to quantum technologies, diagnostics and advanced manufacturing

The program, led locally by Houston Managing Director Jeremy Pitts, has supported 296 Activate fellows since the organization was founded in 2015. Members have gone on to raise roughly $4 billion in follow-on funding, according to Activate's website.

Activate officially named its Houston office in the Ion last year.

Charlie Childs, co-founder and CEO of Intero Biosystems, which won both the top-place finish and the largest total investment at this year's Rice Business Plan Competition, was named to the Activate Anywhere cohort. Read more about the Boston, New York, Berkley and Activate Anywhere cohorts here.

Hardtech fellowship names 11 innovators to inaugural Houston cohort

ready for activation

A national hardtech-focused organization has named its 2024 batch of innovators, which includes the inaugural Houston-based cohort.

Activate named 62 fellows and 50 companies for is latest class, which spans Berkley, California — where the organization is based, Boston, New York, and Houston. Additionally, Activate Anywhere, the program's virtual and remote cohort, was named. According to Activate, it received over 1,000 applicants.

“People, not ideas alone, move the world forward. It is through the drive and determination of brilliant scientists and engineers that we are witnessing true progress,” says Activate CEO Cyrus Wadia in a news release. “Our current Activate Fellows and alumni are already pioneering innovative solutions that make a measurable difference. We’re thrilled to support the next 62 visionaries who will lead the charge in addressing our most urgent issues through groundbreaking science and technology.”

It's the first year Activate has hosted a Houston-based cohort. The organization initially announced its expansion early last year. The inaugural cohort has 11 fellows across energy, materials, life sciences, space, and other sectors.

The named Houston fellows selected for the 2024 class include:

  • Krish Mehta, founder and CEO of Phoenix Materials, a company that decarbonizes concrete using industrial waste.

Exclusive: Hardtech-focused program announces Houston expansion, seeks local leader

changing the world

An organization that directs support to scientists developing impactful technology has decided on Houston for its fifth program.

Activate was founded in Berkeley, California, in 2015 to bridge the gap between the federal and public sectors to deploy capital and resources into the innovators creating transformative products. The nonprofit expanded its programs to Boston and New York before launching a virtual fellowship program — Activate Anywhere, which is for scientists 50 or more miles outside one of the three hubs.

"Our mission is to empower scientists to reinvent the world by bringing their research to market," Aimee Rose, executive managing director of Activate, tells InnovationMap. "There's so much technical talent that we educate in this country every year and so many amazing inventions that happen, that combining the two, which is the sort of inventor/entrepreneur, and giving them the support mechanisms they need to get on their feet and be successful, has the potential to unlock an incredible amount of value for the country, for the environment, and to address other social problems."

This year, Activate is planting seeds in Houston to grow a presence locally and have its first set of fellows in 2024. While Activate is industry agnostic, Rose says a big draw from Houston is the ability to impact the future of energy.

"We're super excited about Houston as an emerging ecosystem for the clean energy transition as being the energy capital of the world, as well as all the other emerging players there are across the landscape in Houston," Rose says. "I think we can move the needle in Houston because of our national footprint."

The first order of business, Rose says, is hiring a managing director for Activate Houston. The job, which is posted online, is suited for an individual who has already developed a hardtech business and has experience and connections within Houston's innovation ecosystem.

"We want to customize the program so that it makes the most sense for the community," Rose says about the position. "So, somebody that has the relationships and the knowledge of the ecosystem to be able to do that and somebody that's kind of a mentor at heart."

The program is for early-stage founders — who have raised less than $2 million in funding — working on high-impact technology. Rose explains that Activate has seen a number of microelectronics and new materials companies go through the program, and, while medical innovation is impactful, Activate doesn't focus on pharmaceutical or therapeutic industries since there are existing pathways for those products.

Ultimately, Activate is seeking innovators whose technologies fall through the cracks of existing innovation infrastructure.

"Not every business fits into the venture capital model in terms of what investors would expect to be eventual outcomes, but these these types of businesses can still have significant impact and make the world a better place," Rose says, explaining how Activate is different from an incubator or accelerator. "As opposed as compared to a traditional incubator, this is a very high touch program. You get a living stipend so you can take a big business technical risk without a personal risk. We give you a lot of hands on support and mentoring."

Each of the programs selects 10 fellows that join the program for two years. The fellows receive a living stipend, connections from Activate's robust network of mentors, and access to a curriculum specific to the program.

Since its inception, Activate has supported 104 companies and around 146 entrepreneurs associated with those companies. With the addition of Houston, Activate will be able to back 50 individuals a year.

Houston startup expands nationally, teams win DOE prize, and more local innovation news

short stories

As Houston ramps up for fall, the city's innovation news has followed suit, and there might be some headlines you may have missed.

In this roundup of short stories within Houston startups and tech, Houston angel investors dole out prize money, the DOE grants Houston innovators some cash, a digital health company expands, and more.

2 Houston teams win DOE geothermal manufacturing prize

This week, the U.S. Department of Energy announced that two Houston-based companies have won the American-Made Geothermal Manufacturing Prize — a $4.65 million competition to incentivize innovators to use 3D printing, or additive manufacturing, to address the challenges associated with operating sensitive equipment in harsh geothermal environments, per a press release. The competition challenged participants with quickly developing, testing, and revising prototypes using additive manufacturing to support the advancement of geothermal tools and technologies.

“This DOE competition harnesses breakthroughs in additive manufacturing to help overcome barriers to widespread deployment of geothermal energy,” says Alejandro Moreno, deputy assistant secretary for renewable power, in the release. “The rapid prototype development supported by this prize is spurring advancements in the geothermal industry to help power the nation from the heat beneath our feet.”

The competition launched in January 2020, and the finalists presented their innovations at the annual Geothermal Rising conference in Reno, Nevada. The winning teams each were awarded $500,000 in cash and up to $200,000 to test their innovations in the field. The two Houston-based winning teams were:

  • Team Downhole Emerging Technologies: "This team developed an alternative to traditional packer systems," the release states. "The all-metal, retrievable packer system is designed specifically for high temperatures, extreme pressures, and corrosion experienced in geothermal wells. The Downhole Emerging Technologies’ partnership resulted in the production of the largest Inconel additively manufactured component by Proto Labs, Inc. and the development of DET’s tool, the Diamond ETIP (Extreme Temperature Isolation Packer).”
  • Team Ultra-High Temperature Logging Tool: "This team developed a technology that uses a labyrinthian heat sink to reduce thermal emissivity and increase the exposure time of temperature sensitive electronic components," according to the release. "Oak Ridge National Laboratory used a powder bed laser fusion technique to manufacture the heat sink design, with the aim that the technology would solve limitations around maximum temperature rating and lifetime of electronics in logging and measurement tools. The team also worked closely with Sandia National Laboratories to test the logging prototype in a high-temperature setting."

Koda Health expands across the country

Houston-based Koda Health has announced via LinkedIn that it has expanded into a handful of new states recently: Florida, Oregon, North Carolina, Virginia, California, and Maryland. These six expansions have all been announced over the past month following the announcement in July that the company is going nationwide.

"Every state has different regulations and requirements for their advancecare planning documents. So, the folks at Nixon Gwilt Law and Koda Health have been hard at work making our platform compliant in every single state," the company announced in a post. "It's hard work, but we're committed to helping patients stay in control of their health care journey, regardless of where they call home."

Koda Health was born out of the TMC's Biodesign Fellowship and launched by Tatiana Fofanova, Dr. Desh Mohan, and Katelin Cherry in March of 2020. The platform uses AI to help patients create advanced medical care directives and documents, such as a living will, through its proprietary machine learning approach.

In February, Koda closed over $3 million in seed funding in order to grow its staff and support expansion. Now, including Texas, Koda is in seven states across the country.

The Houston Angel Network announced its investment of over $160,000 in Hoth Intelligence, the winner of HAN’s prize at the 2022 Rice Business Plan Competition.

“Following the HAN award announcement at the RBPC banquet, we learned that the Houston Chapter of The Indus investor Entrepreneurs (TiE) was also interested in Hoth as an investment for its members," says HAN Chairman Richard Hunter in a news release.

The organizations collaborated on due diligence and negotiation of the investment terms. Hunter led HAN's due diligence and Jeff Tomlinson led the effort on behalf of TiE.

The company, which was established at University of Pittsburgh, has developed an artificial intelligence platform for health care providers. The company's RBPC prize initially totaled $386,700 in investment awards from a handful of entities.

Per HAN's news release, Houston investment firms Prosalus Capital Partners joined in with a $300,000 investment and PiFei VC contributed an additional $100,000.”

“Several companies at the 2022 RPBC, including Hoth Intelligence, ranked very high in the TiE judging," says TiE Houston Chapter President Ram Shenoy. "We therefore decided to pursue due diligence and were very pleased to have worked with HAN to expeditiously complete the deal. To date, it has attracted TiE investors from chapters in Atlanta, Silicon Valley, and Southern California who have committed over $154,000 in investment.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”

AI-powered Houston startup helps restaurants boost customer loyalty

order up

It’s no secret that restaurant trends move fast and margins run thin. And with the proliferation of platforms like Uber Eats, DoorDash and Easy Cater, customer loyalty is fleeting.

The solution?

How about an AI-powered restaurant technology platform that helps restaurant brands cut back on third-party platforms in favor of driving direct discovery, conversion and loyalty?

Enter Saivory. Founded in 2025 by Stephen Klein, a software investor, and Fajita Pete’s restaurateur Hugh Guill, the Houston-based startup aims to help eateries better understand and activate guest behavior across digital channels as AI increasingly reshapes how consumers discover and engage with brands.

In less than a year, Saivory has partnered with Shipley Do-Nuts and Fajita Pete’s to bring AI-powered ordering to life.

“With Saivory, we were able to answer the question of, ‘what if the ordering process could be reduced to a single step, where customers simply tell us what they want and AI takes care of the rest?’” Klein tells InnovationMap.

The Houston-based startup made such an immediate impact that it was selected as a semi-finalist during Start-Up Alley at MURTEC, the restaurant industry’s leading technology conference, which took place last month in Las Vegas.

“Houston is a great hub for technology innovation, and we were proud to represent the city at MURTEC this year,” says Klein. “We didn’t win, but we were able to talk about some of the work that we have existing in the market for clients right now and a little bit about what we’re working on in the future.”

In the current restaurant technology ecosystem, the third-party aggregators own the customer attention that brings volume to restaurants, while also taking big commissions and having control over the end relationships with the customer.

That can often make it difficult for restaurants to grow loyalty and repeat business from customers. Saivory aims to level the playing field for restaurants, helping them stay more connected to their customers.

Take Saivory’s recent application with Shipley’s Do-Nuts, for example.

Saivory powered the donut giant’s AI-ordering and launched Shipley's website and mobile app to support its over 300 locations in Texas alone.

Shipley’s new AI-powered assistant helps users create personalized order recommendations based on individual or group preferences. And unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size. It can also be used for large catering orders.

“They're seeing more traffic to the site and they're seeing when customers use our AI-enabled flows,” Klein says. “And they're seeing higher basket sizes, bigger tickets, by about 25 percent.”

Klein says Saivory’s technology helps strengthen first-party digital relationships, reduce friction and cart abandonment, improve average order value, and delivers personalized, efficient experiences.

“It’s a win-win: the customer gets the right order quickly, while the restaurant gets a bigger margin,” he adds.

Additionally, the technology makes it easier for restaurants to share rewards, loyalty and discounts, ultimately growing more direct traffic and making restaurants less reliant on third-party delivery apps.

Next up for Saivory is adding new components to its platform to enhance the relationship between restaurant and customer, as well as technology around making it easier for restaurants to get found on Google.

“A lot of people are still searching for the best donuts near me,” Klein says. “Or what’s the best Mexican food near me? Customers will increasingly move to AI, where they’re going to ask where they should eat dinner and expect it to just order them dinner. They will eventually expect the technology to know how to do that. So that’s what we’re driving at.”

Houston leads U.S. in population growth for 2025, Census says

Boomtown

Imagine that the Houston metro area swallowed a city the size of Pearland in just one year. That’s essentially what happened from 2024 to 2025, with the Houston metro ranking first in the U.S. for population growth based on the number of people.

New estimates from the U.S. Census Bureau show the 10-county Houston metro added 126,720 residents from July 1, 2024, to July 1, 2025. That’s just shy of Pearland’s roughly 133,000-resident tally.

To calculate population, the Census Bureau counts births, deaths, new residents, and moved-away residents.

Region’s population approaches 8 million

On July 1, 2025, the Houston metro’s population hovered slightly above 7.9 million, up 1.6 percent from the same time in 2024. In the very near future, the region’s population should break the eight million mark.

This follows massive growth in the past 20 years. From 2005 to 2025, the region’s population soared by 39 percent. By comparison, the growth rate from 2021 to 2025 sat at nine percent.

A forecast from the Texas Demographics Center indicates that under a middle-of-the-road scenario, the Houston metro’s population will reach nearly 8.5 million in mid-2030 and more than 9.5 million in mid-2040.

Dan Potter, director of Rice University’s Houston Population Research Center, attributes much of the region’s population surge to people moving to the area from outside the U.S. In Harris County, this means a combination of military personnel returning home, people living or working overseas coming back to the U.S., and immigrants relocating to the U.S., he tells CultureMap.

But Harris County fell short from 2024 to 2025 when it comes to people moving here from elsewhere in the U.S., according to Potter. Counties surrounding Harris County benefited from that trend, drawing new residents who preferred to settle in the suburbs.

“The incredible pull and attraction of the Houston area is its economy, its people, and its affordability, and the significant growth that was observed in 2024 and again in 2025 speaks to the magnetism of the region,” Potter says. “That pull to Houston is too strong to be turned off overnight.”

Cooling economy and immigration shifts slow down growth

Whether looking at urban or suburban places, population growth in the Houston area slowed in 2025 and appears to be slowing even more this year, Potter says.

“A cooling economy and changes to immigration policy are a one-two combination that could knock out the region’s population growth,” says Potter, citing the region’s addition of a less-than-expected 14,800 jobs in 2025 as an example.

Weaker population growth may not be felt evenly across the metro area, according to Potter.

A continuing influx of people from Houston to outlying counties such as Brazoria, Fort Bend, Liberty, Montgomery, and Waller could curb growth in Harris County, Potter said. Why? If the number of people arriving from other other countries flattens or even drops, then there could be “doughnut-style population growth for the next few years, where Harris County and Houston see declines while the suburban counties see an increase.”

Harris County represents 40 percent of region’s population lift

Houston-anchored Harris County accounted for almost 40 percent of the region’s population spike from 2024 to 2025. In one year, Harris County grew by 48,695 residents, or 1 percent, pushing its population past five million. That increase put Harris County in first place for numeric growth (rather than percentage growth) among all U.S. counties.

From 2020 to 2025, Harris County’s growth rate was 6.6 percent. It remains the country’s third largest county based on population, behind Southern California’s Los Angeles County and Illinois’ Chicago-anchored Cook County.

Harris County is on track to surpass Cook County in size in the near future. As of July 1, 2025, a nearly 150,000-resident gap separated population-losing Cook County and fast-growing Harris County.

The Texas Demographics Center predicts Harris County’s population will be 5.37 million in mid-2030 and just short of six million in mid-2040.

Suburban counties see significant population gains

Harris County isn’t the only county in the area that experienced a growth spurt from 2024 to 2025:

  • Waller County’s population climbed 5.69 percent, winding up at 69,858. Its growth rate ranked second among U.S. counties.
  • Liberty County’s population rose 4.4 percent to 121,364, putting its growth rate in eighth place among U.S. counties.
  • Montgomery County gained 30,011 residents, with its population landing at 781,194. That placed it at No. 4 among U.S. counties for numeric growth.
  • Fort Bend County picked up 24,163 residents, arriving at a total of 975,191 and positioning it at No. 8 among U.S. counties for numeric growth. Fort Bend County, the region’s second largest county based on population, is projected to break the one million-resident mark by July 2030, according to the Texas Demographics Center.

“Lower mortgage rates from 2009 to 2022 and the rise of remote work have made suburban housing more attractive, especially for families seeking affordability,” Pramod Sambidi, the Houston-Galveston Area Council’s assistant director of data analytics and research, said last year. “Additionally, suburban areas are seeing more multifamily developments than before the pandemic.”
