A clinical stage pharmaceutical company based in Houston has entered into the next phase of testing out a drug that could be used to treat COVID-19.

Moleculin Biotech Inc. has tapped an independent lab to examine the antiviral activity of its WP1122 portfolio in a COVID-19 animal model. The drug was originally developed as a cancer-fighting glycolysis inhibitor and submitted for its COVID-19 treatment patent in April.

"With in vivo studies for the treatment of COVID-19 in such high demand, we are excited to begin an in vivo study involving our WP1122 portfolio," says Walter Klemp, chairman and CEO of Moleculin, in a press release. "Even though we may have initial observations earlier, having the final data readout in December will push the estimated window for filing an Investigational New Drug application into 2021.

"We are also planning to conduct other in vivo studies, intended to enable us to file a complete IND with the US Food and Drug Administration."

The in vivo study, which would use the lab's hamster model and SARS-CoV-2. Moleculin Biotech expects to have the data from the study in December.

"We are excited about the additional in vitro testing as this will involve more than one molecule from our WP1122 anitmetabolite portfolio against SARS-CoV-2 and other viruses," says Klemp.

Moleculin Biotech was founded by Klemp in 2007 and went public in 2016. The company is based in the Memorial Park area of Houston.

These 7 Houston health tech companies are providing COVID-19 solutions

startups to the rescue

It's all hands on deck in Houston in the battle against coronavirus — and local biotech startups have risen to the occasion.

From mental health solutions and online portals to virtual medicine and new treatments, these Houston companies have recently launched or pivoted to new options in health care.

Mental Health Match

Mental Health Match, a Houston-based startup that uses tech to easily connect people to mental health professionals, has announced the opportunity for 100 Texas residents to get their first appointment free and remotely.

The company cites data that shows:

  • A 78 percent increase in Texans who are concerned about their marriage
  • A 71 percent increase in Texans concerned with their parenting or their children
  • A 35 percent spike in Texans feeling panicked

"You might be practicing social distancing, but you are not alone. It is easier to make it through this together if you can get support and guidance from a skilled professional. That's why we're working with therapists across Texas to provide a free session to individuals who need it most," says Ryan Schwartz, founder of Mental Health Match, in a news release.

Texans can apply for the free sessions online on a first-come, first-served basis.

Houston-based Medical Informatics has created a virtual ICU program, called Sickbay, and the tech tool is being used to remotely monitor patients in Houston Methodist. The program works around the clock from a control hub to use artificial intelligence and algorithms to monitor patients.

The company, which recently moved into its office in TMCx+, announced major growth in January, just ahead of the coronavirus outbreak.

"We designed our Sickbay platform to give lost data back to doctors, nurses and other members of the care team so they could save more lives," says Vincent Gagne, vice president of product for MIC, in a news release. "In fact, our apps are built in collaboration with our clients, such as Texas Children's Hospital and Houston Methodist. Having these facilities blocks away from our headquarters accelerates that collaboration and development."

MolecularMatch, a Houston startup focused on clinical informatics, has launched a free portal that accumulates research and clinical trials for COVID-19. The company is a tenant of TMCx+ and a portfolio company of Houston-based venture capital group GOOSE.

"The number of therapeutic cures and vaccines being tested are growing at an astounding rate," says Eric Pulaski, CEO at MolecularMatch, in a news release. "Our tools make it easier for clinicians and patients to find the help they need. Hopefully, we can help save lives by shortening the time it takes to get more patients into clinical trials and by speeding up research to find cures and vaccines."

The product uses the company's artificial intelligence-backed curation platform and is updated every two to three days.

Luminare

Founded in 2014, Houston-based health care software startup Luminare Inc. seeks to prevent sepsis, a life-threatening reaction to a host of infections that causes about one-third of U.S. hospital deaths. Recently, though, Luminare pivoted to address another health concern — the threat of the novel coronavirus.

After the novel coronavirus surfaced, Luminare retooled its sepsis-detection platform to create a free online self-assessment test for people who suspect they've contracted the virus. The test, available at CheckForCorona.com, helps someone figure out whether they should seek a coronavirus test.

An online screening typically takes less than two minutes. The confidential, secure assessment complies with guidelines from the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO). Based on your assessment results, you might be directed to contact your local health department or, in the worst-case scenario, call 911. Click here to read more.

Denver-based Manatee was just announced to be selected for the 2020 TMCx cohort, and — while programming is beginning virtually — the startup will be enroute to Houston as soon as it's safe. Manatee focuses on providing connected, everyday therapy for kids.

In light of the effects of COVID-19 on both parents and children, Manatee has allowed users to register for three months free. Individuals can apply online.

Moleculin Biotech Inc.

Houston-based Moleculin Biotech Inc., a clinical stage pharmaceutical company that typically focuses on cancer treatment, announced that it has filed for a new patent for its use of one of its products to be used against the coronavirus and other potential viruses.

This patent application is for Moleculin's WP1122, and the company has entered into a partnership with a major Texas university to advance its research.

"We've actually been working on the antiviral potential of WP1122 for some time now," says Walter Klemp, Moleculin's chairman and CEO, in a news release, "but the rise of COVID-19 has obviously placed a new sense of urgency on what we are doing. We hope to be generating animal data on WP1122's antiviral potential in the near term."

Pulmotech Inc.

Experiments conducted by clinical-stage, Houston-based biotechnology company Pulmotect Inc. show its PUL-042 inhaled drug has proven effective in protecting mice against two types of coronavirus: severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Researchers performed those tests at the University of Texas Medical Branch at Galveston.

In the Galveston experiments, a single inhaled dose of PUL-042 protected lab mice from the SARS virus, and it greatly reduced the amount of virus in their lungs after the mice became infected with SARS or MERS.

"With the risks of virulent coronaviruses and other threats increasing, as shown by the recent outbreak in Wuhan that has already spread from China to other countries including the United States, Pulmotect is optimistic that its immune-stimulating technology could be useful in mitigating the threats of current and emerging pathogens and protecting vulnerable populations," says CEO Dr. Colin Broom in a news release.

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.

9 Houston-based companies make Fortune Global 500 list in 2026

Worldwide Rankings

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.

Fast-growing Houston real estate startup surges to No. 7 on Inc. 5000

growth report

Houston-based Epique Realty has ridden the AI wave to rank among the Inc. 5000’s 10 fastest-growing private companies.

With three-year revenue growth of 23,210 percent, the AI-powered real estate brokerage appears at No. 7 on this year’s Inc. 5000 list. The 2026 list ranks private companies based on percentage revenue growth from 2022 to 2025.

Epique, founded in 2021, also ranks as the No. 1 fastest-growing company in Houston, No. 1 fastest-growing real estate company in the U.S., and No. 2 fastest-growing company in Texas.

Epique’s annual revenue surpasses $91 million

Between 2022 and 2025, the company’s annual revenue skyrocketed from $391,654 to more than $91.2 million. In 2025, the brokerage closed more than 23,000 deals and surpassed $7 billion in total sales, elevating Epique to the country’s 14th-largest real estate brokerage as measured by volume.

Epique’s network has more than 4,000 agents.

“To debut in the top 10 of the Inc. 5000 is absolute proof that when you relentlessly put agents first, exponential growth takes care of itself,” co-founder and CEO Joshua Miller said in a news release.

“We didn’t achieve this by following the industry playbook; we achieved this by burning it,” Miller added. “By fully funding our agents’ success through free health care, proprietary AI, and world-class leads, we’ve built a company where agents can finally thrive.”

The company’s other co-founders are Chris Miller, chief operating officer and vice president of expansion, and Janice Delci, chief financial officer.

Epique expands business to Canada, Mexico, Australia

The Millers and Delci have guided the company’s rapid expansion.

“Scaling our corporate support team to match [our] hyper-growth while seamlessly expanding across all 50 states and internationally to Canada, Australia, and Mexico takes an incomparable operational infrastructure,” Miller said.

“We have built an enterprise-grade technology ecosystem that allows us to absorb overhead and empower our agents at lightning speed,” he added. “This ranking validates that our disruptive model is working, and it is completely redefining the global industry standard.”

Epique launched its platform in 2023, touting itself as the industry’s first AI-powered brokerage. The startup’s platform provides AI tools for real estate agents to improve their marketing, streamline content creation, and boost engagement with clients and prospects.

Among Epique’s AI tools are:

  • ChatGPT for generation of property descriptions
  • AI-assisted creation of blog posts and agents’ bios
  • Production of Instagram quotes for social media marketing

“When we started Epique, we wanted to build a company that genuinely cared for its agents’ financial and physical well-being,” Delci says. “To see that vision translate into this level of historic record-breaking growth is a beautiful testament to the true power of radical generosity.”

Epique and fellow honorees will be recognized Oct. 14-16 at the 2026 Inc. 5000 Conference & Gala in Dallas.
