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."

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."

NASA signs on latest tenant for new Exploration Park campus, now underway

space hub

Exploration Park, the 240-acre research and commercial institute at NASA's Johnson Space Center, is ready for launch.

Facilities at the property have broken ground, according to a recent episode of NASA's Houston We Have a Podcast, with a completion date targeted for Q4 2026.

The research park has also added Houston-based KBR to its list of tenants. According to a news release from the Greater Houston Partnership, the human spaceflight and aerospace services company will operate a 45,000-square-foot food innovation lab at Exploration Park. KBR will use the facility to focus on customized food systems, packaging and nutrition for the low Earth orbit economy.

“Exploration Park is designed for companies in the space ecosystem, such as KBR, to develop, produce, and deploy innovative new technologies that support space exploration and commerce,” Simon Shewmaker, head of development at ACMI Properties, the developer behind Exploration Park, said in the GHP release. “This project is moving expeditiously, and we’re thrilled to sign such an innovative partner in KBR, reflecting our shared commitment to building the essential infrastructure of tomorrow for the next generation of space innovators and explorers.”

NASA introduced the concept of a collaborative hub for academic, commercial and international partners focused on spaceflight in 2023. It signed leases with the American Center for Manufacturing and Innovation and the Texas A&M University System for the previously unused space at JSC last year.

“For more than 60 years, NASA Johnson has been the hub of human space exploration,” Vanessa Wyche, NASA Johnson Space Center Director, said in a statement at the time. “This Space Systems Campus will be a significant component within our objectives for a robust and durable space economy that will benefit not only the nation’s efforts to explore the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth.”

Texas A&M is developing the $200 million Texas A&M Space Institute, funded by the Texas Space Commission, at the center of the park. The facility broke ground last year and will focus on academic, government and commercial collaboration, as well as workforce training programs. ACMI is developing the facilities at Exploration Park.

Once completed, Exploration Park is expected to feature at least 20 build-to-suit facilities over at least 1.5 million square feet. It will offer research and development space, laboratories, clean rooms, office space and light manufacturing capabilities for the aerospace, robotics, life support systems, advanced manufacturing and artificial intelligence industries.

According to the GHP, Griffin Partners has also been selected to serve as the co-developer of Exploration Park. Gensler is leading the design and Walter P Moore is overseeing civil engineering.

Houston cleantech co. plans first-of-its-kind sustainable aviation fuel facility

coming soon

Houston-based Syzygy Plasmonics announced plans to develop what it calls the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF).

The facility, known as NovaSAF 1, will be located in Durazno, Uruguay. It is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to the company.

"This is more than just a SAF plant; it's a new model for biogas economics," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "We're unlocking a global asset class of underutilized biogas sites and turning them into high-value clean fuel hubs without pipelines, costly gas separation, or subsidy dependence.”

The project is backed by long-term feedstock and site agreements with one of Uruguay's largest dairy and agri-energy operations, Estancias del Lago, while the permitting and equipment sourcing are ongoing alongside front-end engineering work led by Kent.

Syzygy says the project will result in a 50 percent higher SAF yield than conventional thermal biogas reforming pathways and will utilize both methane and CO2 naturally found in biogas as feedstocks, eliminating the need for expensive CO2 separation technologies and infrastructure. Additionally, the modular facility will be designed for easy replication in biogas-rich regions.

The new facility is expected to begin commercial operations in Q1 2027 and produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel. The company says that once fully commercialized the facility will produce SAF at Jet-A fuel cost parity.

“We believe NovaSAF represents one of the few viable pathways to producing SAF at jet parity and successfully decarbonizing air travel,” Best added in the release.

Houston company ranks No. 13 worldwide on Forbes Global 2000 list

World's Biggest Companies

More than 60 Texas-based companies appear on Forbes’ 2025 list of the world’s 2,000 biggest publicly traded companies, and nearly half come from Houston.

Among Texas companies whose stock is publicly traded, Spring-based ExxonMobil is the highest ranked at No. 13 globally.

Rounding out Texas’ top five are Houston-based Chevron (No. 30), Dallas-based AT&T (No. 35), Austin-based Oracle (No. 66), and Austin-based Tesla (No. 69).

Ranking first in the world is New York City-based J.P. Morgan Chase.

Forbes compiled this year’s Global 2000 list using data from FactSet Research to analyze the biggest public companies based on four metrics: sales, profit, assets, and market value.

“The annual Forbes Global 2000 list features the companies shaping today’s global markets and moving them worldwide,” said Hank Tucker, a staff writer at Forbes. “This year’s list showcases how despite a complex geopolitical landscape, globalization has continued to fuel decades of economic growth, with the world’s largest companies more than tripling in size across multiple measures in the past 20 years.”

The U.S. topped the list with 612 companies, followed by China with 317 and Japan with 180.
