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

money moves

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 medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
