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.”

Chicago life science innovation firm names Houston leader

who's who

After announcing its expansion into Houston last summer and opening its office in a new Texas Medical Center building, Portal Innovations has named its Houston leader.

Portal Innovations announced that Monique Knighten as an executive director in Houston in a LinkedIn post this week. She has over 15 years of experience in supporting research scientists and clinicians working to develop therapeutics in labs and clinics. According to her LinkedIn, she's served in the position since November.

Prior to her new role at Portal, Knighten worked as a manager level at Sartorius Stedim in Houston for five years. Before that role, she served as a technical sales consultant in Texas at Miltenyi Biotec, primarily in the immuno-oncology therapeutic market in the TMC.

Portal first announced its expansion into Houston in June of last year.

“Houston is one of the fastest-growing cities in the U.S., and home to one of the world’s leading cancer research institutions, The University of Texas MD Anderson Cancer Center,” Portal’s Founder and CEO John Flavin said at the time. “It’s critical for us to open in Texas and leverage nearby pipelines from Rice University, UTHealth Houston, Texas A&M, University of Houston, Baylor College of Medicine, and others across Houston’s innovative life sciences ecosystem. We’re thrilled to work with TMC to help grow tomorrow’s biotech and medtech leaders.”

Portal's local office is in the Helix Park complex's Collaborative Building, which opened in October. Helix Park is a 37-acre mixed-use campus currently under construction. 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.

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 maritime startup raises $43M to electrify vessels, opens new HQ

Maritime Mission

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

New cancer-fighting nanodrug tops Houston innovation news to know

Trending News

Editor's note: The new year brings big Houston innovation news, from pending retirements to new hires and a cancer-fighting nanodrug. Below are the five most-read InnovationMap stories published January 16-30, 2026:

1. Houston team uses CPRIT funding to develop nanodrug for cancer immunotherapy

With a relative five-year survival rate of 50 percent, pancreatic cancer is a diagnosis nobody wants. At 60 percent, the prognosis for lung cancer isn’t much rosier. That’s because both cancers contain regulatory B cells (Bregs), which block the body’s natural immunity, making it harder to fight the enemies within. Newly popular immunotherapies in a category known as STING agonists may stimulate natural cancer defenses. However, they can also increase Bregs while simultaneously causing significant side effects. But Wei Gao, assistant professor of pharmacology at the University of Houston College of Pharmacy, may have a solution to that conundrum. Continue reading.
