Houston-based Energytech Nexus has rebranded.

The cleantech founders community will now be known as Energytech Cypher. Organizers say the new name was inspired by the Arabic roots of the word cypher, ṣifr, which is also the root of the word zero.

"A cypher is a key that unlocks what's hidden," Nada Ahmed, co-founder and chief revenue officer of Energytech Cypher, said in a news release. "And zero? Zero is where every transformation begins, the leap from 0 to 1, from idea to reality, from potential to power. We decode the energy transition by connecting the right founders, the right capital, and the right corporate partners at the right time, because the most important journey in energy is the one that takes you from nothing to something."

Energytech Nexus has rebranded to Energytech Cypher.

Co-founder and CEO Jason Ethier says that the name change better reflects the organization's mission.

"The energy transition doesn't have a technology problem. It has a connection problem," Ehtier added in the release. "The right founders exist. The right investors exist. The right partners exist. What's been missing is the infrastructure to bring them together—to decode the complexity, remove the friction, and make sure the best technologies find the markets that need them. That's what this community has always done. Energytech Cypher is the name that finally says it."

Energytech Cypher, previously known as Energytech Nexus, was first launched in 2023 and has grown from a podcast to a 130-member ecosystem. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, Solidec and many others.

It is known for its flagship programs like the Pilotathon, which connects founders with industry partners for pilot opportunities. The event debuted in 2024.

Energytech Cypher also launched its COPILOT Accelerator last year. The accelerator partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. The inaugural cohort included two Houston-based startups and 12 others from around the U.S.

It also hosts programs like Liftoff, Energy Tech Market, lunch and learns, CEO roundtables, investor workshops and international partnership initiatives.

Last year, Energytech Cypher also announced a new strategic ecosystem partnership with Greentown Labs, aimed at accelerating growth for clean energy startups. It also named its global founding partners, including Houston-based operations such as Chevron Technology Ventures, Collide, Oxy Technology Ventures, and others from around the world.

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite.

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.”

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
