Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

The idea for Splay, a unique device perfect for a mobile workforce, was born on the Rice University campus. Images courtesy

Houston startup founders take one-of-a-kind projection device into manufacturing phase

splay saves the day

A Houston company born out of Rice University has crowdfunded its way into the manufacturing phase of its startup journey.

Arovia, founded by Alex Wesley and George Zhu, has a product that solves some major obstacles people on the go face as they work — or entertain — from home, a hotel, coffee shop, etc. Splay is a unique collapsable, portable device that doubles as both a display and projector.

The founders first launched their product in 2016 and raised over $700,000 from backers on their crowdfunding campaign. After raising investment funding, including an investment from the Texas Halo Fund, Wesley and Zhu recently returned to their crowdfunding roots and ran a 30-day pre-order campaign on Kickstarter during which they sold over $300,000 worth of product.

“We couldn't have made Splay without the Houston Startup Community," Wesley says.

Wesley was an MBA student when he met Zhu, who was working towards a B.S. in Mechanical Engineering, after posting a job description in search of a co-founder, a requirement of the Owlspark program.

“Owlspark accepted the business idea, with the stipulation that I needed to find a co-founder,” says Wesley. “I sent out a job description, and a big part of the application process was to provide ideas for making this crazy idea work. I sent the job description at around 9 pm and received an email from George at around 1 am with an extremely detailed proposal. That was the start; and since then, we’ve basically been like brothers — I’ve even lived with him and his parents in China.”

Wesley credits Owlspark as an important part of their formation, beyond the impetus for their partnership.

“It was a great experience for us. The focus on customer interviews is something that is very easy to avoid, but it’s extremely important. You don’t have a product if nobody wants to buy it — you don’t have a company without customers," Wesley says. "During our time at Owlspark, we did over 100 customer interviews, which gave a lot of insight into the viability of the idea and who it would be useful for. We still utilize many of those insights today.”

But Owlspark wasn’t the only accelerator program that Wesley and Zhu joined. They also participated in Hax, a top hardware-focused accelerator, and Luminate, a top optics-focused accelerator. They also competed in the Rice Business Plan Competition, which Wesley says helped them refine their pitch which ultimately secured their funding.

“We pitched at angel groups including the Houston Angel Network and their fund The Halo Fund, Keiretsu Forum and their fund Keiretsu Capital, Rochester Angel Network, and the GOOSE Society. We also won the Texas A&M New Venture Competition,” says Wesley.

With this financial backing, Arovia received the necessary support for the R&D phase for Splay, taking the product into its manufacturing process and pre-sale campaign.

“Yes, it went very well,” shares Wesley, adding that they are still looking for support on the Indiegogo campaign. “Now we are focusing on pre-selling in other markets, like Japan."

Splay can be used as a portable screen, or the projector can be removed to be used on its own. Photo via Splay

Houston has all the potential to lead the energy transition — it just needs to make sure it has all the right ingredients. According to John Chappell, a key ingredient is blockchain. He explains in a guest article for InnovationMap.

"Houston has earned its title as the Energy Transition Capital of the world, and now it has an opportunity to be a global leader of technology innovation when it comes to carbon emissions reporting," Chappell writes. "The oil and gas industry has set ambitious goals to reduce its carbon footprint, but the need for trustworthy emissions data to demonstrate progress is growing more apparent — and blockchain may hold the keys to enhanced transparency."

When venture capitalist and angel investing expert Kyra Doolan started navigating her own fertility journey, her eyes were opened to a huge market opportunity across femtech. As managing director at Houston-based Texas HALO Fund, she took these opportunities to her team of investors.

"A lot of the issues that face women, are things that are not talked about," she says on this week's episode of the Houston Innovators Podcast, referencing things like miscarriage, injury during childbirth, etc. "For a lot time, women just sat back if they had these issues, and they kept it to themselves, so those problems weren't being addressed."

Doolan says she and other women aren't taught how to manage their own fertility journey, but it doesn't have to be that way. Click here to read more.

Houston-based Empower Pharmacy has celebrated the grand opening of its new $55 million, 86,000-square-foot facility that includes extensive automation, a top-of-the line cleanroom, and equipment that generates purified water, clean steam, and clean compressed air. The space also features a warehouse capable of storing at least nine months of raw pharmaceutical ingredients to minimize supply chain problems.

"This innovative facility, combined with our more than 500 dedicated employees, enables us to increase our operational capacity, allowing us to prepare thousands of custom prescriptions each day for millions of patients across the country," Shaun Noorian, founder and CEO of Empower Pharmacy, says in a news release. "We are setting a new standard for compounded medicine, striving to achieve a superior pharmaceutical experience, from order placement to delivery."

The new Empower Pharmacy facility, at 7601 N. Sam Houston Parkway W., opened earlier this month. Click here to read more.

Houston investor shares why she's focused on funding the future of femtech

HOUSTON INNOVATORS PODCAST EPISODE 98

Successful investors find gaps in the marketplace and direct funds into startups and technologies resolving those gaps. For Kyra Doolan, managing director at Houston-based Texas HALO Fund, femtech represents a huge opportunity for innovation.

While Texas HALO Fund has invested in femtech since its first fund in 2012, Doolan shares on the show how she personally saw an investment opportunity with kegg, a fertility tracking device. Doolan says she and other women aren't taught how to manage their own fertility journey, but it doesn't have to be that way.

"I was at a stage in my life where my eyes were open to the gaps that are out there and the conversations that weren't being had," she says. "In looking into Kegg, it showed me what the market was and how many gapes there were in the market just around fertility."

Texas HALO Fund has a few femtech companies in its portfolio now, and the most recent addition is Houston-based Work & Mother, a company that builds out fully-equipped nursing accommodations in office buildings.

Despite it's growing femtech portfolio, the fund is industry agnostic, though, Doolan says, about a third of the companies Texas HALO Fund invests in reside in the health tech space. What makes HALO different is its focus on early-stage startups.

"We like to get in early," Doolan says. "We're, what you would historically consider 'pre-VC,' but now that's getting a little bit blurred. ... We're some of the earlier capital that's invested, and we continue to make investment as the companies continue to subsequent rounds."

Doolan shares more on her passion for femtech, as well as her advice for founders looking for funding and potential female investors looking to get into investing on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston female-focused health tech pitch competition names big winners

winner, winner

From the comfort of their own homes, several female entrepreneurs accepted investment and pitch prizes at the finals of an inaugural awards program created by a Houston-based, woman-focused health organization.

Ahead of the Ignite Madness finals on Thursday, October 29, Houston-based Ignite Healthcare Network named nine finalists that then pitched for three investment prizes. The finalists included:

Eden Prairie, Minnesota-based Abilitech Medical — medical device company that creates assistive devices to aid those with upper-limb neuromuscular conditions or injuries.
New Orleans, Louisiana-based Chosen Diagnostics — a biotech company focusing on custom treatment. First, Chosen is focused on creating two novel biomarker diagnostic kits — one for gastrointestinal disease in premature infants.
San Francisco, California-based Ejenta — which uses NASA tech and artificial intelligence to enhance connected care.
Highland, Maryland-based Emergency Medical Innovation — a company focused on emergency medicine like Bleed Freeze, a novel device for more efficiently treating nosebleeds.
Columbia, Missouri-based Healium — an app to quickly reduce burnout, self-manage anxiety, and stress.
Farmington, Connecticut-based Nest Collaborative — digital lactation solutions and support.
Palo Alto, California-based Nyquist Data — a smart search engine to enable medical device companies to get FDA approvals faster.
New Orleans-Louisiana based Obatala Sciences — a biotech startup working with research institutions across the globe to advance tissue engineering and regenerative medicine.
Perth, Australia-based OncoRes — a company that's developing a technology to provide surgeons with real-time assessment of tissue microstructure.

The inaugural event that mixed health care and basketball — two vastly different industries with strong connections to women — attracted support from partners and sponsors, such as Intel, Accenture, Morgan Lewis, Houston Methodist, Johnson & Johnson Innovation, and more, according to Ayse McCracken, founder and board chair of Ignite.

"Our partners and sponsors are an integral part of our organization" says McCracken. "Without each and every one of them, the networks, resources, and commitment to advancing women leaders, we would not have grown so rapidly in just four years and our IGNITE Madness event would not enjoy this vibrant ecosystem that now surrounds female entrepreneurs."

First up in selecting their winner for their investment was Texas Halo Fund. Chosen Diagnostics took home the $50,000 investment.

"While we were impressed by everyone who pitched tonight, one company stood out to us," says Kyra Doolan, managing partner. "[Chosen Diagnostics] exemplifies what we are looking for: an innovative solution, a strong CEO, and a real addressable market."

The second monetary award was presented by Tom Luby, director of TMC Innovation. The award was an $100,000 investment from the TMC Venture Fund, as well as admission to TMCx. The recipient of the investment was OncoRes.

"We are absolutely blown away," says Katharine Giles, founder of Onco. "We've already got a great link to Texas and looking forward to more."

The largest monetary award that was on the table was presented by Wavemaker Three-Sixty Health, a leading Southern-California based, early stage venture capital firm, for $150,000. However, at the time of the announcement, Managing Partner Jay Goss decided to award four startups an undisclosed amount of investment. Goss says he and his team will meet with each company to establish an investment.

The companies that were recognized by Wavemaker were: Healium, Ejenta, Emergency Medical Innovation, and Nest Collaborative.

Lastly, Ignite itself had $27,500 cash awards to give out to the pitch competition winners. The funds will be distributed between the winners. OncoRes took first place, Abilitech came in second place, and Obatala Sciences took third place.

5 Houston-area companies named among world's most innovative for 2026

In The Spotlight

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned praise on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

Houston-based Vaulted Deep, No. 3 in catchall “other” category.
XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.

UH lands $11.8M for first-of-its-kind early language development study

speech funding

Researchers at the University of Houston have secured an $11.8 million grant from the National Institutes of Health to conduct a first-of-its-kind study of early language development.

Led by Elena Grigorenko, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Psychology, and research professor Jack Fletcher, the study will follow 3,600 children aged 18 to 24 months to uncover how language skills develop at this critical stage and why some children experience delays that can influence later growth.

The NIH funding will also support the development of the new national Clinical Research Center on Developmental Language Disorders at UH, which aims to bring experts from psychology, education, health and measurement sciences to study how children learn language.

“This will be the first national study to estimate how common late talking is using a large, representative sample of Houston toddlers,” Grigorenko said in a news release. “By following these children as they grow, we hope to better understand the developmental pathways that can lead to conditions such as developmental language disorder and autism.”

UH’s team will partner with the pediatric clinic network at Texas Children’s Hospital, where children will be screened for early language development, allowing researchers to identify those who show signs of delayed speech. Next, researchers will follow the cohort through early childhood to examine how language abilities evolve and how early delays may lead to later challenges.

The Clinical Research Center on Developmental Language Disorders will be the 14th national research center established at UH, and will include researchers from multiple UH departments, as well as partners at Baylor College of Medicine and the Texas Center for Learning Disorders.

“This level of investment from the National Institutes of Health reflects the significance of this work to address a complex challenge affecting children, families and communities,” Claudia Neuhauser, vice president for research at UH, said in a news release. “By bringing together experts from multiple disciplines and partnering with major health systems across the region, the project reflects our commitment to advancing discoveries that impact our community.”

Rice Alliance names Houston healthtech exec as first head of platform

new hire

The Rice Alliance for Technology and Entrepreneurship has named its first head of platform.

Houston entrepreneur Laura Neder stepped into the newly created role last month, according to an email from Rice Alliance. Neder will focus on building and growing Houston’s Venture Advantage Platform.

The emerging platform, which is being promoted by Rice Alliance and the Ion, aims to connect founders with the "people, capital and expertise they need to scale."

"I’ve spent a lot of time thinking about what it takes to make an innovation ecosystem more navigable, more connected, and more useful for founders," Neder said in a LinkedIn post. "I’m grateful for the opportunity to do that work at Rice Alliance, alongside a team with a long history of supporting entrepreneurship and innovation."

"Houston has the talent, institutions, and industry base to create real advantage for founders," she added. "I’m looking forward to listening, learning, and building stronger pathways across the ecosystem."

Neder most recently served as CEO of Houston-based Careset, where she helped bring the Medicare data startup to commercialization. Prior to that, Neder served as COO of Houston-based telemedicine startup 2nd.MD, which was acquired for $460 million by Accolade in 2021.

"Laura brings a rare combination of founder empathy, operational experience and ecosystem leadership," Rice Alliance shared.

Neder and Rice Alliance also shared that the organization is hiring developers to design the new Venture Advantage Platform. Learn more here.
