Pharmaceutical giant Eli Lilly has acquired Houston biotech startup CrossBridge Bio, which develops antibody-drug conjugates for cancer, in a deal worth up to $300 million. The deal was celebrated by TMC Venture Fund and the University of Texas Health Science Center at Houston last week.

CrossBridge, founded in 2023, is developing ADCs based on research by Kyoji Tsuchikama and Zhiqiang An, both of UT Health Houston. Tsuchikama is an associate professor of medicinal chemistry and a globally recognized ADC pioneer, and An is a professor of molecular science and vice president of drug discovery.

Antibody-drug conjugates (ADCs) are a potent combination of targeted therapy and chemotherapy that kills cancer cells while saving healthy tissue.

Clinical trials for CrossBridge’s primary ADC candidate, CBB-120, are expected to start this year, pending approval from the U.S. Food and Drug Administration (FDA).

“I’m proud of how well our team has executed and advanced our platform in such a short time since the company’s founding,” Michael Torres, co-founder and CEO of CrossBridge, said in a news release. “By becoming a part of Lilly, a leader in patient-focused therapeutic development, we are well-positioned to further accelerate the clinical potential of this approach.”

Under the Lilly deal, CrossBridge shareholders were expected to receive an upfront payment along with a follow-up payment based on the achievement of certain milestones.

In 2024, CrossBridge closed a $10 million seed round. Among the investors in CrossBridge are the Texas Medical Center Venture Fund, CE-Ventures, Alexandria Venture Investments, Portal Innovations, Linden Lake Labs, and the Cancer Prevention and Research Institute of Texas (CPRIT). It was formed in TMC Innovation’s Accelerator for Cancer Therapeutics program."Built within the TMC ecosystem, CrossBridge Bio grew with the support, funding, and resources that helped shape its trajectory. TMC led the company's early financing and watched it evolve from its earliest days to its acquisition by Eli Lilly," William McKeon, president and CEO of the Texas Medical Center, shared in a LinkedIn post. "[This is a] strong reminder that breakthrough science and the right early backing can change what’s possible."

    TMC breaks ground on collaborative Houston research center

    in the works

    A fall 2023 opening is set for a research center under construction at the Texas Medical Center's new TMC3 life science campus.

    The 250,000-square-foot TMC3 Collaborative Building will house research initiatives organized by the Texas Medical Center, University of Texas MD Anderson Cancer Center, Texas A&M University Health Science Center, and University of Texas Health Science Center at Houston. Construction began in January.

    "The founding institutions behind [this building] are among the world's leading innovators in health and science. Their work at both the bench and bedside saves lives. The entire spirit behind this building reflects a joint investment — both financially and strategically — in lifesaving research, data collaborations, and technologies," William McKeon, president and CEO of Texas Medical Center, says in a September 20 news release.

    Located at the heart of the 37-acre TMC3 campus and facing the site's Helix Gardens, the $185.8 million, four-story building is designed to foster collaboration among academic healthcare institutions and industry partners. Within the building, the three academic healthcare partners will create a 43,000-square-foot joint research lab. Furthermore, a 7,000-square-foot, 500-seat atrium will be available for lectures and other activities.

    Beyond space shared by TMC3's four founders, 85,000 square feet of lab and office space will be developed for industry partners, and MD Anderson will create a 14,000-square-foot space for strategic initiatives. The building also includes 14,200 square feet that will host TMC's strategic initiatives; Braidwell, a life science-focused investment firm; the TMC Venture fund; and national venture and equity and partners.

    "This project represents a once-in-a-generation opportunity for Houston's academic medical community to collaborate together and with industry to advance our missions and accelerate knowledge and cures," says Dr. Peter WT Pisters, president of MD Anderson.

    "By breaking down silos and bringing clinicians and scientists together in this resource-rich location to speed new therapies to market from regenerative medicine and advanced imaging to drug discovery and data sciences, we will have the ability to translate discoveries into preventions and treatments for patients in need," adds Jon Mogford, chief operating officer and senior vice president of Texas A&M Health.

    Houston health center working with new study that uses app to track long-term COVID-19 effects

    pandemic innovation

    Aided by technology, medical sleuths at the University of Texas Health Science Center at Houston are tracking the long-term effects of COVID-19 as part of a national study.

    At the heart of the study is an app that allows patients who have shown COVID-19 symptoms and have been tested for COVID-19 to voluntarily share their electronic health records with researchers. The researchers then can monitor long-term symptoms like brain fog, fatigue, depression, and cardiovascular problems.

    UTHealth is one of eight U.S. sites for the INSPIRE trial (Innovative Support for Patients with SARS COV-2 Infections Registry). Researchers are recruiting study participants from Memorial Hermann-Texas Medical Center. They want to expand recruitment to urgent care clinics in the Houston area.

    Aside from accessing patients' data through the Hugo Health platform, UTHealth researchers will ask participants to fill out brief follow-up surveys every three months over the course of 18 months. The study complies with the Health Insurance Portability and Accountability Act of 1996 (HIPAA), the federal law that protects patients' information from being disclosed without their knowledge.

    "This is a very novel and important study," Dr. Ryan Huebinger, assistant professor in the Department of Emergency Medicine at UTHealth's McGovern Medical School and co-principal investigator of the study, says in a news release.

    In a study like this, researchers typically must see a patient in person or at least reach out to them.

    "Using this platform is novel because we don't have to schedule additional appointments or ask questions like 'How long were you hospitalized?' – we can automatically see that in their records and survey submissions," Huebinger says.

    Mandy Hill, associate professor in the McGovern Medical School's Department of Emergency Medicine and the study's co-principal investigator, says about one-fourth of the people in the study will be local residents who didn't test positive for COVID-19.

    "That group will be our control group to be able to compare things like prevalence and risk factors," Huebinger says.

    Eligible participants must be at least 18 years old, must have experienced COVID-19 symptoms, and must have been tested for COVID-19 in the past four weeks.

    "This is not going to be the last pandemic. The more information we can gather across communities now will give us a leg up when the next pandemic happens," Hill says, "so that we can be more prepared to take steps toward prevention."

    Researchers hope to sign up at least 300 study participants in Houston. The entire INSPIRE trial seeks to enroll 4,800 participants nationwide. The study is supposed to end in November 2022.

    "There's such great potential for numerous research findings to come out of this study. We could find out if people in Houston are suffering from post-COVID-19 symptoms differently than other parts of the country, whether minorities are more affected by long-hauler symptoms, and if certain interventions work better than others," Hill says.

    The U.S. Centers for Disease Control and Prevention (CDC) is financing the study. Aside from UTHealth, academic institutions involved in the research are:

    • University of Texas Southwestern Medical Center in Dallas
    • Rush University Medical Center in Chicago
    • Yale University in New Haven, Connecticut
    • University of Washington in Seattle
    • Thomas Jefferson University in Philadelphia
    • University of California, Los Angeles
    • University of California, San Francisco

    Houston cancer-fighting researchers granted over $30 million from statewide organization

    just granted

    The Cancer Prevention and Research Institute of Texas has again granted millions to Texas institutions. Across the state, cancer-fighting scientists have received 55 new grants totaling over $78 million.

    Five Houston-area institutions — Baylor College of Medicine, the University of Houston, The University of Texas Medical Branch at Galveston, The University of Texas Health Science Center at Houston, and the The University of Texas MD Anderson Cancer Center — have received around $30 million of that grand total.

    "These awards reflect CPRIT's established priorities to invest in childhood cancer research, address population and geographic disparities, and recruit top cancer research talent to our academic institutions," says Wayne Roberts, CPRIT CEO, in a news release. "I'm excited about all the awardees, particularly those in San Antonio, a region that continues expand their cancer research and prevention prowess. San Antonio is poised to have an even greater impact across the Texas cancer-fighting ecosystem."

    Four grants went to new companies that are bringing new technologies to the market. Two companies with a presence in Houston — Asylia Therapeutics and Barricade Therapeutics Corp. — received grants in this category.

    Last fall, CPRIT gave out nearly $136 million to Texas researchers, and, to date, the organization has granted $2.49 billion to Texas research institutions and organizations.

    Houston ranks among world’s top 30 emerging startup ecosystems

    Startup Status

    Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

    The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

    Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

    According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

    In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

    Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

    Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

    “For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

    KBR names C-suite duo to lead $5.3B government services spinoff

    new leaders

    In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

    Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

    “Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

    LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

    SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

    “SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

    After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

    Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

    Experts: Houston's VC ecosystem has set the foundation — now we need scale

    guest column

    Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

    A Houston energy story in the national recovery

    The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

    The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

    By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

    From foundation to scale

    The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

    What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

    Houston in context

    The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

    At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

    The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

    Where this leads

    Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
