When the pandemic hit and shut down businesses across the world, Ayse McCracken knew immediately what group of people were likely going to be the most affected: Women in health care. It just so happens that her nonprofit organization, Ignite Healthcare Network, exists to serve this same group of people, so she got to work on creating online events that were intentional and meaningful.

"With COVID, it has only escalated the importance of our work, so we've elevated our voices through our webinar series," McCracken says on this week's Houston Innovators Podcast.

This week, Ignite's virtual startup competition concludes with the finals. She shares more about the program and Ignite's mission on the episode. Click here to read more and stream the episode.

Restaurants have undoubtedly suffered due to loss of business during the shutdown, but they face an uphill battle back to normalcy, and restaurateur Philipp Sitter knew his tech tool could help. He created VIPinsiders as a marketing tool to reach customers in a data-driven way.

"The restaurant gets to know me [the customer], it understands how often I visit, it also gets to reward my visitation," explains Sitter. "Most importantly, it reminds me to come back when I haven't visited in a while."

Data recorded by VIPinsiders shows that 48 percent of users visit restaurants with the platform "more often" in the first 90 days. Click here to read more.

Just a few weeks after being hospitalized from COVID-19, Diane Yoo was investing in a medical device startup that could have made a world of difference to her recovery. After closing its initial fund, Medingenii invested in several Houston health startups including Vitls, a wearable device that can track and send vitals remotely.

"The pandemic has really validated some of the business models we're invested in," she tells InnovationMap.

Now, fueled by her first round of success and eager to advance other life-changing technologies, Yoo is looking toward a second fund. Click here to read more.

Houston investor recovers from COVID-19 — then funds startups innovating solutions for the disease

While so many of Houston's venture capital groups and entrepreneurs have been figuring out the best ways to navigate fundraising amid a pandemic, Diane Yoo managed to close an oversubscribed initial fund and deployed investments into health tech startups during COVID-19 — while also recovering from the disease itself.

Entrepreneur turned investor Diane Yoo launched her health tech-focused venture capital fund, Medingenii Capital, last year, but didn't start fundraising for its initial fund until this year.

Yoo says she and her partners, entrepreneur and investor Greg Campbell, neurologist Dr. Eddie Patton, Dr. Sreedhar Mandayam, and investor Gen Fukunaga, were virtually meeting with over a dozen potential investors weekly and closed the round in under two months.

It was right around closing when Yoo says she caught COVID-19.

"It ravaged every part of my body, and I ended up having to be hospitalized because I couldn't breathe," she says.

Yoo recovered after a month and a half of enduring the disease, only to come out of that experience to fund innovative Houston companies working on COVID-19 solutions. Medingenii focuses on early stage health tech, including genomics, health IT, medical devices, and patient engagement.

"The pandemic has really validated some of the business models we're invested in," she tells InnovationMap.

One example from Medingenii's portfolio is Houston-based medical device company, Vitls. The company's technology includes a wearable device that can monitor vital signs and sync with a smartphone app and sends key information to doctors remotely.

As Yoo thinks back to her COVID-19 treatment, Vitls could have helped her and her fellow patients get out of the crowded hospital wing and home to recover sooner — with the peace of mind of remote care thanks to the device.

"When I was in the ER room, it was overcrowded," Yoo says. "If you were not seriously ill, they would dismiss you because there was just no room. But if you went home with Vitls, you could have sent all your vitals to your doctor from home."

Fueled by a mission to find more health tech solutions like Vitls and with the quick pace of her first fund — Yoo says she's already deployed the capital into Houston-based startups and is looking toward the second fund, which will again focus on Houston startups.

"We really love Houston," Yoo says. "We want to invest a lot of our fund here, and we continue to do that and plan to do that. We see a lot of opportunity in Houston and look forward to working with the innovation ecosystem here."

Houston startup aims to flip the script on social media marketing

anti social media

Social media companies are using user data for their own financial gain, but what if users had a cut in the profits? That's the business model for Houston-based Social Chains.

"Social Chains is a social media platform of real people, real privacy, and real rewards," says Srini Katta, founder and CEO of the company. "We're fixing three problems in the social media industry."

The first problem is that user data has market value, but only the Facebook, Google, and other platforms are reaping the rewards, not the user, who's the backbone of the platform. User privacy and a growing number of fake accounts are the other issues Social Chains addresses. Katta says he realized that most importantly, users should own their data

"On our platform, the user is a stakeholder. Our platform distributes 50 percent of the profits to the users," he says.

User privacy is protected and encrypted on this new platform, and users must register with a government-issued identification. Social Chains prevents fake accounts by using facial recognition.

The biggest differentiating factor of this platform is that users make real money, but it's kept track by the site's token system, which uses blockchain technology, and users receive some of the so-called "S tokens" just for signing up. And, businesses only pay for the ads that users engage with. For instance, for a marketing email, businesses will only pay for the emails that were actually opened. It's a win-win situation, as the user receives a kickback whenever they open a marketing email or engage with ads.

Social Chains already has 5,000 users and, Katta says, that's with little to no marketing efforts. Currently, he's been working out a few kinks before launching into marketing for the platform, though he expects to do that beginning next month. Most of Social Chain's current users are high school to college students, so that will be the primary demographic for the marketing strategy.

Katta says he first encountered some of the challenges using social media marketing at one of his former startups when attempting to use Facebook ads to grow the company. He says he saw increased engagement, but not as significant of an increase in sign ups on his company page.

"We looked back to see who are the people clicking on the ads," he says. "We looked at their profiles, and they were not from the United States, even though we had given geographic preferences."

He found out that third party ad management platforms were working with Facebook and click farms all around the world to increase engagement results. Katta starting thinking of a solution for this marketing problem.

"Then, in 2016, with the rise of 'fake news,' we realized this was a bigger problem," he says.

In addition to user growth, Katta hopes to grow his investors, and the company is seeking funds for its seed round in 2019.

"To be honest, we need $100 million to build this out, so we're trying to raise money," Katta says. "Personally, I've put in $3.5 million before I took any money from investors. I have a lot of skin in the game."

Currently, Social Chains has three team members, with a fourth joining soon. Diane Yoo, who is a founding member and director of the Rice Angel Network, leads growth and investor relations for the company. One obstacle for the team has been being spread out from Houston to The Woodlands and even Austin.

"I've lived in New York and San Francisco. I moved to Houston because I wanted a quiet place to raise my family," Katta says. "The biggest challenge for Houston, compared to other cities, is other cities are so dense. Houston is so sprawling. It's really hard to network, and meet potential employees."

One of the crucial connectors for Katta has been Station Houston. The team plans on meeting to work together two days a week at Station. In addition to being a great workspace, the area acts as a good hub for potential partnerships for Social Chains. Startups need marketing, of course.

This Houston airport saw sharp passenger decline in 2025, study shows

Travel Talk

A new global airport travel study has revealed passenger traffic at Houston's William P. Hobby Airport (HOU) sharply decreased from 2024 to 2025.

The analysis from travel magazine LocalsInsider examined recently released data from the Bureau of Transportation Statistics (BTS), the U.S. International Trade Association, and a nationwide survey to determine the following American traveler habits: The most popular U.S. and international destinations, emerging hotspots, and destinations on the decline. The study covered passenger travel trends from January through July 2025.

In the report's ranking of the 40 U.S. airports with the sharpest declines in passenger traffic, HOU ranked 13th on the list.

About 4.26 million arrivals were reported at HOU from January through July 2024, compared to about 3.96 million during the same seven-month period in 2025. According to the data, that's a significant 7.1 percent drop in passenger traffic year-over-year, or a loss of 300,974 passengers.

"As travelers chase new hotspots, some destinations are seeing reduced passenger traffic whether due to rising costs, shifting airline schedules, or evolving traveler preferences, some destinations are seeing a decrease in visitors," the report's author wrote.

It appears most major Texas airports had drops in passenger traffic from 2024 to 2025. Dallas Love Field Airport (DAL) saw the worst in the state, with a dramatic 7.4 percent dip in arrivals. DAL also ranked 11th on the list of U.S. airports with the steepest declines in passenger traffic.

More than 5.13 million arrivals were reported at DAL from January through July 2024, compared to over 4.75 million during the same seven-month period in 2025.

This is how passenger traffic has fallen at other major Texas airports from 2024 to 2025:

Austin-Bergstrom International Airport (AUS):

  • 6,107,597 – Passenger arrivals from January to July 2024
  • 5,828,396 – Passenger arrivals from January to July 2025
  • -4.6 percent – Year-over-year passenger change
Dallas/Fort Worth International Airport (DFW):
  • 23,830,017 – Passenger arrivals from January to July 2024
  • 23,251,302 – Passenger arrivals from January to July 2025
  • -2.4 percent – Year-over-year passenger change

San Antonio International Airport (SAT):

  • 2,937,870 – Passenger arrivals from January to July 2024
  • 2,836,774 – Passenger arrivals from January to July 2025
  • -3.4 percent – Year-over-year passenger change
El Paso International Airport (ELP):
  • 1,094,431 – Passenger arrivals from January to July 2024
  • 1,076,845 – Passenger arrivals from January to July 2025
  • -1.6 percent – Year-over-year passenger change

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

As anticipated, Spring-based oil and gas giant ExxonMobil has officially paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters in late November.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
