A new life science-focused venture capital engine has officially opened offices in Houston.

Portal Innovations moved into a space at Helix Park in October. The offices are led by executive director Monique Knighten.

Knighten has been in Houston for 16 years, since she was a postdoc at the University of Texas Institute for Molecular Medicine. “It's like a lot of us. We come for a specific reason, and then we just find reasons to stay,” she says.

And now, that reason is to push the emerging Houston ecosystem forward by helping early-stage startups to build themselves toward success. Portal does that partly by providing capital, but besides cash investments, emerging companies need a physical infrastructure where their work can happen. They also need great people to support their cause at every step of development. To that end, networking and convening with beneficial people is key for Portal.

With locations already in Chicago, Boston and Atlanta, why did Portal choose Houston?

“If you take a look at where lots of scientific publications are coming from, if you look at where a lot of technology that eventually becomes commercialized, a lot of it will come initially from labs that are right here in Houston,” says Knighten. “Houston also has a great quality of life. That's really important so that startups need to be able to have a place where they can have their teams.”

And who has joined Portal in its 30,000-square-foot Helix Park lab space? March Biosciences, a cancer-focused cell therapy startup; Crossbridge Bio, responsible for a cancer therapeutic that just closed a $10 million seed round; Artidis, which is personalizing cancer diagnosis thanks to a new nanomedical biomarker technology; Spanios, which has created human model systems to help researchers better identify therapeutic options for solid tumors; Stingray Therapeutics, a cancer immunotherapy company working on metastatic or advanced solid tumors; Remunity Therapeutics, an immuno-oncology startup developing immune-stimulating antibody-drug conjugates that reactivate anti-tumor immune response; and Phiogen, which is doing promising work in the world of non-antibiotic anti-infectives.

The Cancer Focus Fund, an oncology-focused investment fund in partnership with The University of Texas MD Anderson Cancer Center is also sharing space with the burgeoning biomedical companies.

Even Texas Medical Center CEO Bill McKeon is excited to greet Portal.

“In Portal, we have a partner with a proven track record of leveraging venture capital funding, expert partners and strong programming to support dynamic, entrepreneurial businesses at pivotal moments of their growth. We look forward to building on our collective expertise and shared vision to further support the breakthroughs of early-stage life science ventures,” he says on the company’s website.

By working with Portal, each of the companies will benefit not only from Knighten’s expertise i building teams gathered from her time at Sartorius Stedim Biotech and decade with Miltenyi Biotec, but also that of the other Portal teams. Working on a national scale also gives the brands opportunities for national exposure. Just one more way, Houston’s ecosystem is continuing to move the needle both for the healthcare companies in it and the patients who will one day benefit.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes three innovators across therapeutics, venture capital, and HR software.

Michael Torres, CEO of CrossBridge Bio

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

CrossBri dge 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. Continue reading.

Aileen Allen, venture partner at Mercury

When Aileen Allen was contemplating a big career move — swapping sides of the table from tech company to venture investor — she was motivated by driving gender and experience diversity amongst decision makers.

"I've worked for VC-backed companies for most of my career and had the opportunity as an executive to be in the boardroom during that time," she says on the Houston Innovators Podcast. "One of my takeaways was that very few of my board members looked like me. I had one or two women on any of my boards at a time in totality, and very few of my board members had been operators."

"I'd really like to change that, and I'd like there to be better representation and diversification in the boardroom," she adds. Continue reading.

Confident job seekers have mostly been of the mindset that if they can just get in front of an employer, they can sell themselves into an offer for the open position. The obstacle then, is getting through the screening process to get an actual interview.

Until recently, the price of admission for starting or progressing in a desired career was a resume and cover letter stellar enough to catch the eye of the human resources and recruiting team. Outside of being buried in the immense pile of resumes recruiters do not have the bandwidth to get to, standing out in the sea of candidates can be daunting.

Resumes do not tell the full story as it is and it’s almost impossible for applicants to put their potential, soft skills and work personality into a document to be reviewed. So, what’s the solution?

It is a multi-layered problem, which requires a multi-layered solution, but one of the options gaining steam in the recruitment space is provided by SeekerPitch, a Houston-based HR technology platform utilizing generative AI to make hiring and interviewing more efficient.

“I've noticed that there's a ton of people that slip through the cracks,” says Ryan Reisner, president and founder of SeekerPitch and The Reisner Group. “And we spend all our time interviewing people to see if they have the soft skills. Resumes are hard skills. And now with AI, anybody can build the same exact resume. Everybody can say they have communication skills, leadership skills, and a lot of people say they have those."

Houston biotech startup secures $10M seed round to propel cancer-fighting therapy from bench to bedside

fresh funding

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

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.”

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

As anticipated, Spring-based oil and gas giant ExxonMobil has officially paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters in late November.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
