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.

Diane Yoo, managing partner at Medingenii

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 doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
