A Houston biotech company based off research out of UTHealth Houston has raised seed funding to continue developing its cancer-fighting therapeutic.

CrossBridge Bio, formed during the TMC Innovation’s Accelerator for Cancer Therapeutics program, closed a $10 million seed round led by TMC Venture Fund and Crescent Enterprises' VC arm, CE-Ventures. The round also included participation from Portal Innovations, Alexandria Venture Investments, Linden Lake Labs, and several pre-seed investors.

“We are thrilled to have the support of such experienced investors who share our vision of bringing transformative cancer therapies to patients in need,” Michael Torres, CEO of CrossBridge Bio, says in a news release. Torres served as an entrepreneur in residence of ACT.

The company is working on the next-generation of antibody-drug conjugates (ADC) therapeutics that process dual payloads as targeted treatments for a set of challenging cancers. The innovative treatment is based on research from UTHealth experts Dr. Kyoji Tsuchikama and Dr. Zhiqiang An.

“Our dual-payload ADC technology is designed to deliver synergistic therapeutic effects using highly stable linkers that ensure payload release only within the targeted cancer cells, thereby maximizing their therapeutic effectiveness while minimizing the liabilities associated with uptake in unintended tissues, as seen with many of today’s cancer treatments," Torres continues.

He explains that the funding will toward advancing CrossBridge's first development candidate, CBB-120, into preclinical non-GLP toxicology studies in addition to derisking the company’s proprietary linker technology with dual-payload applications, per the release.

As a result of the raise, William McKeon, president and CEO of the Texas Medical Center, and Damir Illich, manager of life sciences of CE-Ventures, will join CrossBridge Bio’s board of directors.

“We are proud to back CrossBridge Bio in their mission to develop the next generation of cancer therapies,” McKeon says in the release. “Their dual-payload ADCs are designed to deliver targeted drug release within cancer cells with greater stability, precision, and control. These breakthrough advancements have the potential to change patients’ lives worldwide and we look forward to helping drive their development.”

Houston startup secures $10M to expand into rural communities

ready to grow

A Houston company that is working on a value-based model for primary care has fresh funding to support its mission.

Hamilton Health Box announced the completion of a $10 million series A funding round led by 1588 Ventures with participation from Memorial Hermann Health System, Impact Ventures by Johnson & Johnson Foundation, Texas Medical Center Venture Fund, and the Sullivan Brothers.

The company, founded in 2019 by Dr. Toby R. Hamilton, will use the funding to fuel its expansion into rural areas to help assist those living in Health Professional Shortage Areas, or HPSAs.

The company has pioneered a proprietary “small footprint primary care delivery model,” which is considered suitable for rural markets, employer worksites, office buildings, schools, and university campuses. The cost-effective microclinics are “prefabricated facilities” that are designed for primary care services, and employ a hybrid in-person and telemedicine care approach.

Hamilton began his career as a physician before founding Emerus Holdings, which is a micro-hospital system in the Houston area that later moved to private equity.

The recently acquired funding will help expedite the high-touch care model to 98 million Americans in HPSAs, which was a goal for when the company was established during the Covid-19 pandemic. HHB has made partnerships with Federally Qualified Health Centers (FQHCs) to provide primary care services both at existing FQHC centers and through new sites in rural areas.

"Hamilton Health Box that was designed to deliver the lowest possible price of primary and preventative care," Hamilton said in a previous interview with Innovation Map. "We built that to be able to take that care to the jobsite and meet the customer where they are at."

Texas Medical Center opens first building in massive Helix Park project

tmc3

For nearly a decade, the Texas Medical Center and its partners have been working on the plans for Helix Park, a 37-acre campus expansion of TMC. As of this week, the first building has opened its doors to the public.

The TMC3 Collaborative Building officially opened today to a crowd of media, public officials, and health care executives. The institutional agnostic, 250,000-square-foot building will anchor Helix Park and house research initiatives from the four founding partners: Texas Medical Center, The University of Texas MD Anderson Cancer Center, Texas A&M University Health Science Center, and The University of Texas Health Science Center at Houston.

“Today, we lay the cornerstone of a new campus fully dedicated to streamlining the commercialization of life-changing innovations in medicine and technologies,” William McKeon, president and CEO of TMC, says at the event. “We are incredibly excited to both welcome our founding institutions and industry partners to the Collaborative Building and to invite the community to experience the Helix Park campus and its beautiful parks with a series of special events in the months ahead."

Established to be a place for academic institution collaboration, the building — designed by Boston-based Elkus Manfredi Architects — will have wet laboratories, office space, and event facilities. Two venture groups — Portal Innovations and the TMC Venture Fund — will also move into the building.

Each institution will bring in select programs and initiatives. MD Anderson will house two institutions within the new building, including the James P. Allison Institute focused on immunotherapy and the Institute for Data Science in Oncology.

"The future of life sciences in Houston is brighter than ever before as we come together to officially open the TMC3 Collaborative Building,” Dr. Peter WT Pisters, president of MD Anderson, says. “Our clinicians and scientists work daily to advance innovations in cancer research and care – all of which will be amplified in this new environment within Helix Park that further cultivates collaboration, connectivity, and creativity.”

UTHealth will move its Texas Therapeutics Institute into the facility.

“With a shared commitment to improving the health and well-being of individuals and communities, we are bringing together academics and industry to accelerate discovery and medical breakthroughs,” Dr. Giuseppe N. Colasurdo, president and Alkek-Williams Distinguished Chair at UTHealth Houston, says. “Through the Texas Therapeutics Institute — already a signature collaborative enterprise at UTHealth Houston — our world-renowned leaders in therapeutic antibody development will have the opportunity to work closely with other leading researchers in the Texas Medical Center, greatly enhancing our collective ability to translate discoveries and ideas into effective treatments.”

Texas A&M, which has worked with Houston Methodist to develop its engineering medical program, will operate its Texas A&M Health’s Institute of Biosciences and Technology in the new space.

“As we open this state-of-the-art facility, we’re opening the door to a new era of collaboration. This building signifies the dismantling of silos to deliver game-changing therapies for the toughest diseases impacting Texans and citizens worldwide,” said John Sharp, Chancellor of The Texas A&M University System. “Texas A&M Health’s Institute of Biosciences and Technology has long been a trailblazer in drug discovery, and now, in the heart of this resource-rich ecosystem of the Texas Medical Center, we’re taking it up a notch. By positioning our scientists near their peers and esteemed clinicians, we’re igniting a spark that will fuel innovation and forge dynamic research programs.”

The next aspect of Helix Park to deliver will be the Dynamic One, a 700,000-square-foot industry research facility. Several other buildings, including a hotel, residential tower, and mixed-use building, are expected to deliver over the next few years. The "spine" of the project is six linked green spaces, designed by landscape architect Mikyoung Kim, that form an 18.7-acre campus, which is shaped like a DNA helix, hence the project's name.

At the opening event, leaders discussed the annual impact of over $5.4 billion expected after the campus is completed, and the 23,000 permanent new jobs and 19,000 construction jobs anticipated from Helix Park.

"Texas truly is the home of innovation. Our energy innovations are legendary, as are our innovations in space," says Texas Governor Greg Abbott, naming several of the state's innovative accomplishments. "Long before all of this innovation we're seeing now, Texas was the home of the Texas Medical Center."

Mayor Sylvester Turner spoke to the importance of collaboration.

"Individually, you can do things very well. Collectively, you can be transformational," he says. "One thing about this city, collaboration is the key. When we play well together, and when we build an integrated, robust ecosystem, everyone wins. That's Houston, and that's the way we operate."

Houston health tech startup secures $16M series A, prepares for first U.S. clinical trials

money moves

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.

Houston investor outlines how rare VCs are in Houston — and how to find them

guest column

As a venture capitalist and former startup founder living in Houston, I get asked a lot about the best way to find and connect with a venture capitalist in Houston. My usual advice is to start with a list, and reach out to everyone on that list. But no one has a comprehensive list. In fact, VCs are such a quiet bunch that I’ve yet to meet someone who personally knows everyone on this proverbial list.

So, I got together with a couple of VC friends of mine, and we put together our own Houston venture capitalist list.

There are, by our count, 11 active venture capital funds headquartered in Houston of any size and type, and outside of corporate venture capital and angel investors, there are 30 total venture capitalists running funds.

Houston has always been quite thin on the VC fund front. I’ve jokingly introduced myself for a while as “one of the 13 venture capitalists in Houston.”

Let’s put this scale in some brutal perspective. With 7.2 million people in the Greater Houston Metro Area, the odds of finding a partner level active venture capitalist in Houston is about 1 in 240,000, if you take a most expanded definition of venture capitalist that might come down to 1 in 100,000. We’re the fifth largest metropolitan area in the country with a tremendous economic engine; there is a ton of capital in Houston, but it’s residing in things like institutional fixed income and equities, real estate, wealth management, corporate, private equity, family office, energy and infrastructure Basically, mostly everywhere but in venture capital funds for tech startups.

By comparison, there are almost as many Fortune 500 CEOs in Houston — 24, by our count — as venture capitalists and fewer venture capitalists than Fortune 1000 CEOs, of which there are 43. That means running into a VC in the checkout line at HEB is about as rare as running into the CEO of CenterPoint, ConocoPhillips, or Academy. In fact, as there are 115 cities in the Greater Houston area, you are three times more likely to be a mayor in Greater Houston Area than a partner at an investor at a VC firm, and more likely to be a college or university president. While we’re at it, you’re 400 times more likely to be a lawyer, 250 times more likely to be a CPA, and over 650 times more likely to be a medical doctor.

Our 30 venture capitalists in the Greater Houston Area are spread across 20 firms and all major venture sectors and stages. Venture capitalist is defined for this list as a full time managing director or partner-level investment professional actively running a venture capital fund with limited partners, currently investing in new venture capital deals from their fund from seed to growth stage, and residing in the Greater Houston Metro area.

To get to 31 we added in a couple of people running venture set asides for PE funds, and a number who work from Houston for funds with no office here. We excluded CVCs, as the decision making is more corporate than individual and rarely includes the committed fund and carried interest structure that defines venture capital, and excluded professionals at angel networks, accelerators, and seed funds that provide investment, but don’t manage conventional venture capital funds, as well as PE funds that do the occasional venture deal. We might be able to triple the number if we include venture capitalists at any professional level, and add in those professionals at PE and angel and seed funds, and corporate venture capital teams who are actively investing. But we’ll get to those other sources of funding in the next list.

The 11 venture capital funds headquartered in Houston are: Mercury, Energy Transition Ventures (my fund), Montrose Lane (formerly called Cottonwood), Texas Medical Center Venture Fund, Artemis, New Climate Ventures, Fitz Gate Ventures, Curate Capital, Knightsgate Ventures, Amplo Ventures,and First Bight Ventures.

Another half a dozen firms have a partner level venture capital investor here, but are headquartered elsewhere: Energy Innovation Capital, Decarbonization Partners, 1984 Ventures, Altitude Ventures, Ascension Ventures, Moneta Ventures, and MKB & Co. Two others, CSL Ventures and SCF Partners, are local private equity funds with a venture capital partner in Houston and a dedicated allocation from a PE fund.

Culling these for partner or managing director level currently in Houston, in alphabetical order by first name, LinkedIn profile and all.

We may have missed a couple of VCs hiding in plain sight, as venture capital is a pretty dynamic business.

VCs are just rare. And yes, perhaps more rare in Houston than in California. Something less than 1 in 100 VCs in the country live in Houston. Across the US there are somewhere around 1,000 to 2,000 active venture capital firms, and maybe another 1,000 to 2,000 active US based CVCs — so, plus or minus maybe at most 4,000 to 5,000 currently active partner level venture capitalists in the country excluding CVC professionals (active VCs and VC funds are really hard to count).

Perhaps in the most stunning statistic, the 7,386 elected state legislators in the US today outnumber the total number of American venture capitalists. Luckily for startup founders, the venture capitalists are more likely to return your phone call.

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.

How Houston's innovation sector fared in 2025 Texas legislative session

That's a Wrap

The Greater Houston Partnership is touting a number of victories during the recently concluded Texas legislative session that will or could benefit the Houston area. They range from billions of dollars for dementia research to millions of dollars for energy projects.

“These wins were only possible through deep collaboration, among our coalition partners, elected officials, business and community leaders, and the engaged members of the Partnership,” according to a partnership blog post. “Together, we’ve demonstrated how a united voice for Houston helps drive results that benefit all Texans.”

In terms of business innovation, legislators carved out $715 million for nuclear, semiconductor, and other economic development projects, and a potential $1 billion pool of tax incentives through 2029 to support research-and-development projects. The partnership said these investments “position Houston and Texas for long-term growth.”

Dementia institute

One of the biggest legislative wins cited by the Greater Houston Partnership was passage of legislation sponsored by Sen. Joan Huffman, a Houston Republican, to provide $3 billion in funding over 10 years for the Dementia Prevention and Research Institute of Texas. Voters will be asked in November to vote on a ballot initiative that would set aside $3 billion for the new institute.

The dementia institute would be structured much like the Cancer Prevention and Research Institute of Texas (CPRIT), a state agency that provides funding for cancer research in the Lone Star State. Since its founding in 2008, CPRIT has awarded nearly $3.9 billion in research grants.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our healthcare community. Now, it’s up to voters to ensure this initiative moves forward.”

More than 500,000 Texans suffer from some form of dementia, including Alzheimer’s disease, according to Lt. Gov. Dan Patrick.

“With a steadfast commitment, Texas has the potential to become a world leader in combating [dementia] through the search for effective treatments and, ultimately, a cure,” Patrick said.

Funding for education

In the K-12 sector, lawmakers earmarked an extra $195 million for Houston ISD, $126.7 million for Cypress-Fairbanks ISD, $103.1 million for Katy ISD, $80.6 million for Fort Bend ISD, and $61 million for Aldine ISD, the partnership said.

In higher education, legislators allocated:

     
  • $1.17 billion for the University of Houston College of Medicine, University of Texas Health Science Center at Houston, UT MD Anderson Cancer Center, and Baylor College of Medicine
  • $922 million for the University of Houston System
  • $167 million for Texas Southern University
  • $10 million for the Center for Biotechnology at San Jacinto College.

Infrastructure

In the infrastructure arena, state lawmakers:

     
  • Approved $265 million for Houston-area water and flood mitigation projects, including $100 million for the Lynchburg Pump Station
  • Created the Lake Houston Dredging and Maintenance District
  • Established a fund for the Gulf Coast Protection District to supply $550 million for projects to make the coastline and ship channel more resilient

"Nuclear power renaissance"

House Bill 14 (HB 14) aims to lead a “nuclear power renaissance in the United States,” according to Texas Gov. Greg Abbott’s office. HB 14 establishes the Texas Advanced Nuclear Energy Office, and allocates $350 million for nuclear development and deployment. Two nuclear power plants currently operate in Texas, generating 10 percent of the energy that feeds the Electric Reliability Council Texas (ERCOT) power grid.

“This initiative will also strengthen Texas’ nuclear manufacturing capacity, rebuild a domestic fuel cycle supply chain, and train the future nuclear workforce,” Abbott said in a news release earlier this year.

One of the beneficiaries of Texas’ nuclear push could be Washington, D.C.-based Last Energy, which plans to build 30 micro-nuclear reactors near Abilene to serve power-gobbling data centers across the state. Houston-based Pelican Energy Partners also might be able to take advantage of the legislation after raising a $450 million fund to invest in companies that supply nuclear energy services and equipment.

Reed Clay, president of the Texas Nuclear Alliance, called this legislation “the most important nuclear development program of any state.”

“It is a giant leap forward for Texas and the United States, whose nuclear program was all but dead for decades,” said Clay. “With the passage of HB 14 and associated legislation, Texas is now positioned to lead a nuclear renaissance that is rightly seen as imperative for the energy security and national security of the United States.”
