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.

cha-ching

Four Houston bioscience startups have collected nearly $43 million in grants from the Cancer Prevention and Research Institute of Texas (CPRIT).

Here’s a list of the four startups, the amount and purpose of each grant, and some background information about each company.

Stingray Therapeutics

CPRIT grant amount: $13,881,458

Purpose of grant: Clinical trial to evaluate an immunotherapy known as SR-8541A for treatment of advanced or metastatic solid tumors.

Company background: Stingray received a $2 million Small Business Innovation Research (SBIR) award in 2022. In conjunction with the award, Mohan Kaadige, a research associate professor at the Translational Genomics Research Institute, joined Stringray as the principal SR-8541A investigator.

“I … believe we have great potential to alleviate cancer suffering in the near future with this exciting technology,” says Kaadige.

March Biosciences

CPRIT grant amount: $13,358,637

Purpose of grant: Clinical trial to evaluate a T-cell immunotherapy (MB-105) for treatment of certain types of relapsed lymphoma.

Company background: March Biosciences, a Baylor College of Medicine spinout, recently received $4.8 million in funding from Cancer Focus Fund, affiliated with Houston’s MD Anderson Cancer Center.

“The breadth and quality of the support we are receiving from our local partners and institutions underscore Houston’s increasing prominence as a worldwide leader in cancer R&D and clinical research,” says Sarah Hein, co-founder and CEO of March Biosciences.

Mongoose Bio

CPRIT grant amount: $10,621,053

Purpose of grant: Development of T-cell therapies targeting solid-tumor cancer.

Company background: Mongoose founder Cassian Lee, a professor and researcher at MD Anderson, is a CPRIT scholar and a participant in Texas Medical Center Innovation’s 2023 Accelerator for Cancer Therapeutics.

“Mongoose Bio is a first-rate example of the use of CPRIT funds to fund a disruptive cell gene therapy … therapeutic with deep roots and origins in Texas. This innovation will benefit patients with solid tumors not just in Texas but the rest of the world,” says CPRIT.

FixNip

CPRIT grant amount: $4,844,088

Purpose of grant: Clinical study and manufacturing of a silicone implant that creates a soft, natural-looking nipple for women with breast cancer who’ve undergone post-mastectomy breast reconstruction. The clinical study will be done at MD Anderson.

Company background: In conjunction with the CPRIT grant, FixNip is moving its headquarters from Israel to Houston. Austin-based CPRIT became aware of FixNip during a May 2022 trade trip to Israel by the organization’s CEO, Wayne Roberts.

“Loss of nipple projection is the most pervasive problem across all currently existing nipple reconstruction solutions,” says FixNip.

Aside from the grants for the four Houston startups, CPRIT handed out two grants for recruitment of two cancer researchers to Houston:

  • $6 million grant to recruit Dr. Leonido Luznik of Johns Hopkins University to the Baylor College of Medicine. Luznik’s research focuses on allogeneic blood and marrow transplantation (alloBMT), a treatment for blood cancers.
  • $1.99 million grant to recruit Swiss researcher Christina Tringides to Rice University. Tringides is working on a “groundbreaking” treatment for brain tumors, says CPRIT.

Houston company wins AHA competition for pediatric heart valve design

winner, winner

Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

EO Houston is where ambitious founders go to scale smarter

Don't Go It Alone

Scaling a business from early traction into true growth is one of the most exciting — and punishing — chapters of entrepreneurship. Houston founders know this better than most. Our city is built on ambition: fast-moving industries, talent from around the world, and opportunities that expand as large as the Texas sky.

But as many entrepreneurs eventually learn, scaling isn’t simply “more of what worked.” It requires new systems, new thinking, and often, a new version of the founder. Even the most capable founders eventually face decisions, pressures, and turning points that only other entrepreneurs can truly understand.

Entrepreneurs’ Organization, a global peer-to-peer network of more than 18,000 business owners across 220 chapters in 75+ countries, exists for exactly this stage. One of the largest chapters in the organization, EO Houston brings that global community to life locally, offering founders the connection, learning, and accountability needed to grow sustainably and to grow up as leaders.

A community where founders learn at the highest level
The real value of EO emerges in the lived experiences of other entrepreneurs. When Houston-area founders talk about the moments growth nearly broke their companies, a universal theme appears: you can’t do it alone.

EO Houston member Robert De Los Santos of Sky High Party Rentals learned this the hard way when rapid post-COVID growth made expansion feel limitless — until it wasn’t.

“After COVID, we doubled every year and assumed inventory was the limit. In 2023 we overbought, only to realize demand had peaked. That taught us a hard truth: growth in one city has ceilings. Expanding into Austin and Dallas — the Texas Triangle — gave us new markets to put our inventory to work while we figured out how to penetrate Houston better. The challenge shifted from a strategy of ‘buy more units for demand’ to learning how to tackle the challenges of ‘leading across cities.’”

Founders often enter EO exhausted from trying to maintain control as things grow more complex. Many discover, like Jarred King of Summit Firms, that scaling requires the difficult shift from doing everything to building the team that can.

“We grew quickly because of my network, relationships, and hustle… but I was doing all the work,” King says. “I realized at that point you have to delegate — not just busy work, but important decisions to your key team, as well as set up really effective SOPs.”

“The uncomfortable truth is that you are no longer the best person for most jobs in your company," agrees Darren Randle of Houston Tents & Events. "Your inability to delegate or hire people smarter than you in key leadership and management level roles will become the single biggest drag on the entire business. You have to accept that your original 'hustle' is now a scalability risk."

Making hard decisions, such as walking away from customers or contracts, can feel like less of a sting when you know others have also been faced with tough choices. Aaron Gillaspie of West U's My Salon Suite recalls, “You can’t be everything to everyone, it’s ok to say no, and just understand some customers aren’t the right fit. It’s a two way street and both must win.”

Perspective is perhaps the most important reality check that members find at EO.

“Bigger volume will not make problems go away — you just got to get used to walking the tightrope," says Roger Pombrol of Emerald Standard. "Develop a system for good balance and do not freak out. Scared is no way to live your life. It’s ok if you fall. Your family will still love you. Money is just money. Love is love. The world tries to make you conflate them, but don’t."

Actionable insights from entrepreneurs who’ve already scaled
Conversations like these are happening every month inside EO Forum Meeting. Each EO chapter is divided into several small Forums. These confidential, committed group of 7–10 entrepreneurs who meet to share the real five percent of what they’re experiencing. It’s not advice, but experience — shared candidly, respectfully, and with the kind of vulnerability that leads to breakthroughs.

What makes Forum so impactful is the honesty it draws out. Entrepreneurs are often surrounded by employees, partners, and even family members who rely on them for answers, but seldom do they have a group where vulnerability is not only welcomed, but expected.

Learning experiences that match your ambition
EO supports that growth far beyond peer groups. Through the organization’s global partnerships with institutions like Harvard, Oxford, and INSEAD, Houston members gain access to executive-level learning experiences designed specifically for entrepreneurs.

These programs help founders step out of the day-to-day and think strategically about competitive advantage, innovation, and organizational leadership. Paired with ongoing learning through EO Jumpstart, Nano Learning, and its global library of member-created content, founders stay informed, challenged, and ahead of emerging trends.

And through global communities — ranging from EO Women and EO Under 35 to industry-specific groups — Houston members tap into expertise that spans continents and sectors. Whether someone is navigating M&A, exploring international expansion, or integrating new technologies, the right perspectives are always within reach.

What truly distinguishes EO Houston, however, is its culture. Houston’s entrepreneurial landscape is uniquely diverse and resilient, filled with founders who are hungry to build, innovate, and elevate the city’s business community. EO Houston amplifies that spirit, creating relationships that are as supportive as they are strategic. Many members describe the chapter not simply as a network, but as a catalyst for becoming better leaders, better thinkers, and — just as importantly — better human beings.

Your next level starts here
For entrepreneurs who are ready to scale—beyond their first million, beyond their current comfort zone, and toward a future that requires sharper leadership and stronger community—EO Houston offers an unmatched platform. It is a place where ambitious founders grow faster, think bigger, and gain the confidence to take bold next steps.

If you’re ready to elevate your business and your leadership alongside people who understand the journey, EO Houston is ready to welcome you. Your next level starts with the peers who can help you reach it. Learn more and become a member here.
