Houston female-focused health tech accelerator names top companies at annual event

you go girls

A Houston organization that accelerates and supports female founders leading innovative health tech startups has concluded its 2024 program with the announcement of this year's top companies.

Ignite Health, an accelerator founded in 2017 by longtime Houston health care professional Ayse McCracken, named its 2024 winners at its annual Fire Pitch Competition in Houston last month. The companies pitched health tech solutions across lung health, renal therapy, breastfeeding tech, and more.

"This year’s competition was a culmination of passion, innovation, and hard work from the top startups in our 2024 Accelerator Program," reads a LinkedIn post from Ignite. "These trailblazing founders earned their spot on the stage by demonstrating exceptional leadership and the potential to revolutionize the healthcare industry with their solutions and devices."

First place winner was Sarah Lee, CEO and co-founder of Relavo, a New York-based company that's making home dialysis more effective, safer, and more affordable. Lee accepted awards from Johnson & Johnson and Wilson Sonsini Goodrich & Rosati.

Therese Canares, CEO and founder of CurieDx, took second place and won its awards from SWPDC - Southwest National Pediatric Device Innovation Consortium and Wilson Sonsini. CurieDx, based in Baltimore, Maryland, is creating remote diagnostic tools using smartphone technology.

In third place is Andrea Ippolito, CEO and founder of SimpliFed, a company focused on democratizing access to baby feeding and breastfeeding services through virtual care that's covered by insurance. The startup won awards from Texas Children's Hospital and Wilson Sonsini Goodrich & Rosati.

Three other finalists won other awards, including:

Houston hospital system scores $4.8M gift, opens new Austin clinic, and more

news roundup

Texas Children’s Hospital has lots of exciting news this month. Chief among its big announcements is a $4.8 million gift that will help to fund the hospital’s new behavioral health Intensive Outpatient Program (IOP) in The Woodlands.

The donation comes from Ovintiv, a natural gas exploration and production company headquartered in Denver, Colorado.

The pledge makes Ovintiv the first company sponsor to join the Council of Hope, Texas Children’s new corporate giving society. The council’s fundraising priorities include supporting Texas Children’s behavioral health initiatives. Texas Children’s formed a Behavioral Health Task Force last year in order to expand and upgrade services for patients who need specialized help, hopefully preventing the necessity of in-patient care.

The IOP is expected to open early next year. It will treat patients for four or five hours a day, using individual, group and family therapy, art and music therapy programs, and yoga and recreational therapy to improve outcomes in behavioral health.

“This IOP is desperately needed in the Woodlands, and we are committed to creating it because we believe that the behavioral and developmental health of children, adolescents and teens is just as important as their physical well-being. Ovintiv’s transformational gift will make a life-changing difference for so many patients and their families,” says Dr. Kirti Saxena, chief of psychiatry at Texas Children’s Hospital and associate professor of psychiatry and behavioral sciences at Baylor College of Medicine, in a press release.

The Woodlands, however, isn’t the only city seeing the debut of a new facility from Texas Children’s. Last week, Texas Children’s Pavilion for Women announced the grand opening of its obstetrics and gynecology clinic in North Austin. The location welcomes women for fertility management, prenatal and preventative care, and a full spectrum of gynecological services.

That’s just the beginning for Texas Children’s and its reach in central Texas. In addition to the new OB/GYN clinic, Texas Children’s Hospital North Austin will open its doors in early February. It will provide care for women and children, especially in the areas of maternal-fetal medicine, and fetal intervention and neonatology.

Additionally, the Houston hospital has been named a Center of Excellence in antimicrobial stewardship (AMS) by bioMerieux, a world leader in in vitro diagnostics. Texas Children’s is one of three in the United States to net the honor, and the only one that specializes in pediatrics.

It’s no secret that antimicrobial resistance (AMR) is a bête noire of hospitals around the world. Common infectious diseases are becoming increasingly difficult to treat. By ensuring that patients get the right drug, at the right dose, at the right time, antimicrobial stewardship is extremely important to fighting resistance and to continuing antibiotic efficacy for future generations.

Texas Children’s and bioMérieux will collaborate to further activate antimicrobial resistance measures that will improve patient care. They’ll share expertise to develop and scale innovative best practices based on the application of diagnostic technology. And through all of its innovations, Texas Children’s will continue to be a global leader in pediatric care.

Houston hospitals soar on annual list ranking best in Texas

top health care

Houston Methodist Hospital now shares its status as the state’s best hospital with Dallas’ UT Southwestern Medical Center.

In U.S. News & World Report’s latest ranking of Texas hospitals, Houston Methodist and UT Southwestern share the No. 1 spot. Last year, Houston Methodist was the lone holder of first-place honors in Texas.

The Houston Methodist system comprises a primary care facility within the Texas Medical Center and six community hospitals across the region. In all, Houston Methodist operates more than 2,600 patient beds and employs more than 29,700 people.

Overall, Houston hospitals fared well in this year’s Texas rankings:

  • Houston Methodist, No. 1
  • Baylor St. Luke’s Medical Center, No. 3
  • Memorial Hermann Hospital-Texas Medical Center, No. 4
  • Memorial Hermann Greater Heights Hospital, No. 6
  • Houston Medical Sugar Land Hospital, No. 9
  • Memorial Hermann Memorial Medical Center, No. 10

Specialty institutions in Houston also garnered accolades.

For instance, the University of Texas MD Anderson Cancer Center ranked first in the country for cancer care. Since the inception of the U.S. News & World Report survey in 1990, MD Anderson has been among the country’s top two institutions for cancer care.

“At MD Anderson, we remain singularly focused on eliminating cancer,” Dr. Peter WT Pisters, president of MD Anderson, says in a news release. “We are pleased to see this commitment recognized, but there is work still to be done.”

For its part, Houston Methodist nabbed national rankings in 10 specialties, including No. 4 for diabetes and endocrinology and No. 5 for gastroenterology and GI surgery.

Elsewhere in the Houston area:

  • Texas Children’s Hospital nailed down the No. 1 ranking among children’s hospitals in the state.
  • TIRR Memorial Hermann was again ranked as the Best Rehabilitation Hospital in Texas.
  • The Texas Heart Institute at Baylor St. Luke’s Medical Center claimed the No. 2 ranking among cardiovascular, heart, and vascular surgery facilities in the state.
  • The Menninger Clinic again makes the top 10 psychiatric hospitals. It ranked No. 7 in that specialty.

“A recent survey of U.S. News users revealed more than four in five (84 percent) consider a hospital’s quality metrics to be important factors when deciding where to seek treatment for a serious medical issue,” Ben Harder, chief of health analysis and managing editor at U.S. News, says in a news release. “Consumers want useful resources to help them assess which hospital can best meet their specific care needs.”

Harder adds that his publication’s hospital rankings “offer patients and the physicians with whom they consult a data-driven source for comparing performance in outcomes, patient satisfaction, and other metrics that matter to them.”

Houston hospital opens next phase in $245M expansion

now open

Texas Children's Hospital has announced the opening of its newest medical tower in the Texas Medical Center.

Pavilion for Women Tower II is now open to patients, the Texas Children's Hospital revealed this week. It's the second phase of a $245 million expansion within the TMC. The new tower houses women’s services outpatient clinics and connects to the Pavilion for Women via a new sky bridge,

“I’ve always said that outgrowing a space is a good problem to have because it means that we’re doing something right and our patients and their families trust us to provide the safe and high-quality care they deserve,” says Mark A. Wallace, president and CEO of Texas Children’s, in a news release. “I am so proud of everything we’ve done together and I’m beyond grateful and excited for the continuous growth of Texas Children’s Pavilion for Women.”

The Pavilion for Women continues to grow its medical services, according to the release, including "pelvic medicine and reconstructive surgery, menopause treatment, maternal fetal medicine care, the Texas Children’s Fetal Center, reproductive psychiatry, reproductive endocrinology and infertility, and minimally invasive gynecology surgery."

“This latest milestone is one more indication of the dedication of Texas Children's Hospital to women's health,” Dr. Michael Belfort, OB/GYN-in-chief at Texas Children’s Pavilion for Women and professor and chair of the Department of Obstetrics and Gynecology at Baylor College of Medicine, says in the release. “That's very, very important to me. For the first time in this country, a children's hospital has embraced women throughout the spectrum of their health care from birth to menopause.”

The Baylor Obstetrics and Gynecology will relocate to the new tower by the end of the year. In 2024, TCH will add more adult inpatient and neonatal intensive care beds.

“This investment in our Pavilion for Women will allow us to increase delivery volumes significantly, but additionally the added space will also allow us to continue to grow those specialized clinics that cater to women at every stage of their life,” says Michele Birsinger, assistant vice president of Women's Services at Texas Children’s Pavilion for Women.

The Texas Medical Center is also undergoing a major renovation to create Helix Park, a complex with a few new multidisciplinary buildings for research, innovation, and health care. The first of the buildings, the TMC3 Collaborative Building, is expected to deliver this year.

As director of social innovation at Teach For America Houston, it's Sarah Essama's job to come up with new ways for the organization to support both students and teachers. But, as she explains on the Houston Innovators Podcast this week, Essama realized a huge lesson modern students needed was to learn this innovation process themselves.

This line of thinking turned into Essama founding The Dream Lab, powered by Teach for America Houston.

"The Dream Lab is a set of immersive design spaces where young people leverage their imagination and creativity to innovate and solve problems within their community," she explains.

Last month, the new concept rolled out to high school students in partnership with DivInc Houston, a nonprofit focused on social and economic equity in entrepreneurship, and 21 ninth graders spent the day at the Ion for a mini-innovation accelerator and design showcase. Click here to read more.

A Houston-based virtual reality training provider has closed its first round of funding. HTX Labs announced last month that it has received a $3.2 million investment from Cypress Growth Capital.

“We have been looking to secure outside capital to accelerate the growth of our EMPACT platform and customer base but we hadn’t found the right partner who provided an investment vehicle that matched our needs,“ says HTX Labs CEO Scott Schneider in the release. “We found everything we were looking for in Cypress Growth Capital. They have a non-dilutive funding model that aligns with our capital expectations and have the level of experience that really makes this smart money.

The fresh funding will go toward growing and scaling the company's operations — both within the current Department of Defense and expansion opportunities into key commercial markets, like heavy industry, manufacturing, and higher education. Additionally, the funding will support increased customer adoption. Click here to read more.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
