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.

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.

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 university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
