For the third time in his career, serial entrepreneur Steve Latham recession activity, so he feels confident he knows the playbook of how to handle what's on the horizon. For his latest venture, Donate Stock, a tech platform that simplifies stock donation for both the donor and the beneficiary, he's focused on weathering whatever storm is incoming.

"We've raised more money to extend our runway, and we're keeping a super tight lid on expenses because your cash is your oxygen," he says. "There are companies going out of business in our industry right now that had really promising businesses but just spent too much money before they could get to the revenue phase."

He shares the background story on DonateStock and his own career on last week's Houston Innovators Podcast episode. Read more and stream the episode.

Innovation and equity are two things they have to go together — and Houston Methodist knows that. Which is why Arianne Dowdell serves as vice president and chief diversity, equity and inclusion officer at Houston Methodist. Under her leadership, the health care provider is putting the patients at the forefront of the hospital system's priorities through its DEI initiatives.

In an interview with InnovationMap, Dowdell shares more about these ongoing initiatives and her role, as well as the importance of DEI in innovative health care.

"It doesn't matter if you're down here in the medical center or out in Baytown," she says. "The innovation and what we're thinking about and the technologies and the way that we communicate with our patients, all that is part of innovation, which helps our DEI initiatives become more successful in everything that we're doing."

A clinical-stage biotech company based in Houston has announced the closing of its $15.25 million IPO.

Coya Therapeutics, now trading under the ticker COYA, announced this week that its IPO — previously disclosed in December — has closed its initial public offering of 3,050,000 shares of its common stock and accompanying warrants to purchase up to 1,525,000 shares of common stock, per a news release. Howard Berman, CEO of Coya Therapeutics, has lead the company since February of 2021. Read more.

Houstonian and serial entrepreneur plans to scale nonprofit fintech tool

Houston innovators podcast episode 167

Donating stock can be a smart way to offload assets and optimize a donation — but Steve Latham thought it was so cumbersome a process that it didn't even feel worth it.

"It was such a hassle that I never did it again," says Latham on the Houston Innovators Podcast.

That opportunity for innovation stuck with Latham as he advanced his career in AdTech in New York before moving back to Houston a few years ago. A serial entrepreneur, Latham was an early co-founder of the Houston Technology Center.

His latest venture is DonateStock — a tech platform that simplifies stock donation for both the donor and the beneficiary. The early version of Latham's vision was to clear up the lack of communication the original process had — nonprofits receiving stock donations were never notified about who made each donation.

The next phase for the fintech company, as Latham explains on the show, is to scale this idea by way of channel distribution, rather than just directly working between donor and nonprofit. He says he wants DonateStock to be a featured as an "easy button" option wherever donations are accepted online.

"Now that we've proven and shown that our process works," he says, "let's scale that to make that button available to the 20 or so online donation platforms."

In order to accomplish this goal, Latham is preparing to fundraise early this year, but it's a challenging time for fintech amid economic uncertainty, he says. So far, the company has raise $2.25 million from within the company's network along with angel and family office investment.

This is the third time in Latham's career that he's seen this recession activity, so he feels confident he knows the playbook of how to handle what's on the horizon.

Latham shares more about the difference his company is making within the nonprofit sector, as well as his passion for Houston and its local tech ecosystem — which he's seen grow up from afar — on the podcast episode. Stream the episode below, or wherever you listen to your podcasts.

Houston fintech startup snags Capital Factory's $50,000 pitch investment prize

winner, winner

Capital Factory, one of the most active startup investors with a presence across Texas, recently hosted a virtual pitch competition — and one Houston startup took home the big prize.

As a part of the Houston Tech Rodeo, Capital Factory hosted its $50K Houston Investment Challenge with five finalists — DonateStock, Elastique, Elemental Coatings, M&S Biotics, and ScalaMed. The panel of judges included Andy Cloyd, vice president of Revolution; Aleece Hobson, venture partner at HX Venture Fund; and Juliana Garaizar launch director of Greentown Labs.

DonateStock, a tech-enabled tool that automates the stock donation process, took home the big win. Steve Latham, founder and chairman of DonateStock, presented the company's pitch and explained how the tool has the potential to unlock $100 billion for nonprofits.

"A lot of people aren't aware about the benefits of donating stock," Latham explains. "If you're sitting on stock that you've owned or several years that's appreciated quite a bit. If you sell it, you pay capital gains tax — anywhere from 15 to 30 percent. If you donate it, you avoid the tax and you get a big write off, you can deduct the full market value of the donated stock."

He goes on to explain how only 2 percent of people donate stock — and its due to the archaic process that it takes. DonateStock's platform optimizes the education of donors, the connection of nonprofits to new donors, and the simplification of the process. What used to take hours now takes just 10 minutes, Latham says.

Nonprofits get a free page, free customer support, and there is no fee to be on the platform, and DonateStock makes a 2 percent transaction fee. The company already has 40 nonprofits on the platform, and over 70 in the queue to sign up. The goal, Latham says, is to have 900 organizations online by the end of the year. He's already seen a lot of interest in light of the pandemic.

"This is the time to solve this problem," Latham says. "If you have friends at nonprofits or charities, you know what the pandemic did to giving programs. They've all been devastated and they have gotta find new ways to diversify and grow their revenue."

DonateStock anticipates a seed round later this year. It's the third startup Latham has worked on with his co-founder.

"We see a path to building a billion-dollar company over the next five years while impacting millions of lives around the world," he says.

Each of the other finalists' consolation prize is a connection and a foot in the door at Capital Factory, says CEO Joshua Baer.

"Every time we do one of these, we meet a bunch of companies that we end up working with — and many of whom we end up investing in," he says at the virtual event. "We're going to be following up with all of the companies from today. Anyone who was a finalist and up on the stage is someone we are excited about and interested in working more closely with."

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.
