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.

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."

Former NASA astronaut, official joins Venus Aerospace board

astronaut appointment

Retired Air Force colonel and former NASA astronaut Pamela Melroy, who previously served as deputy administrator of NASA, recently joined the board of directors at Houston-based Venus Aerospace.

Venus Aerospace, a startup founded in 2020, develops rocket engine technology, including rotating rocket detonation engines for hypersonic flights. These engines promise higher power, greater fuel efficiency and lower emissions than conventional rocket engines or jet engines, according to the Interesting Engineering website. The global rocket propulsion market is expected to grow from $9.5 billion in 2025 to $29.9 billion by 2034, according to a forecast by ResearchAndMarkets.com.

“Advanced rocket propulsion has been of interest to me for over a decade, and Venus Aerospace’s recent achievements in demonstrating the stability of rotating detonation rocket engines represent a significant development,” says Melroy, who left NASA earlier this year and is now a self-employed consultant living in Arlington, Virginia.

Melroy, a member of the United States Astronaut Hall of Fame, has built an illustrious career in the aerospace sector. Aside from being a NASA official, she was:

One of only two female astronauts to command a space shuttle mission
Deputy program manager of Orion space exploration initiatives at aerospace and defense contractor Lockheed Martin
Senior technical adviser and director of field operations for the Federal Aviation Administration’s Office of Commercial Space Transportation, where she came up with the first safety guidelines for commercial human spaceflight
Deputy director of the Tactical Technology Office at the Defense Advanced Research Projects Agency (DARPA).
An adviser for the establishment of the Australian Space Agency

Venus Aerospace said in a news release that as a leader at three federal agencies, “Melroy shaped America’s strategy in space, accelerated commercial space partnerships, and deepened space exploration.”

Sassie Duggleby, co-founder and CEO of Venus Aerospace, called Melroy “a preeminent leader in the world of aerospace.”

In May, Venus Aerospace completed the inaugural test flight of its rotating detonation rocket engine. The startup, whose headquarters is at the Houston Spaceport, says it’s the only company in the world that has manufactured a flight-proven, high-thrust rotating detonation rocket engine.

On the horizon for Venus Aerospace is production of Stargazer M4, a high-speed aircraft capable of two-hour global travel.

Venus Aerospace’s investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. The startup also gets support from the Air Force Research Laboratory (AFWERX), the Air Force, NASA and DARPA.

Jordan Blashek, co-founder and managing partner of America’s Frontier Fund, which backs startups creating breakthrough technologies, said his firm’s investment in Venus Aerospace “underscores our focus on supporting American companies that are revolutionizing industries of the future.”

“With recent hypersonic advancements from China and Russia, safeguarding American innovation and securing our industrial base has never been more urgent,” Blashek added. “Venus Aerospace is poised to redefine hypersonic flight and ensure America’s continued leadership in aerospace innovation.”

Since its founding, Venus Aerospace has raised $78.3 million in investments, according to PitchBook data.

Texas-based energy startup raises $1 billion on heels of Houston expansion

Powering Up

Austin-based startup Base Power, which offers battery-supported energy in the Houston area and other regions, has raised $1 billion in series C funding—making it one of the largest venture capital deals this year in the U.S.

VC firm Addition led the $1 billion round. All of Base Power’s existing major investors also participated, including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed Venture Partners, Andreessen Horowitz (a16z), Altimeter, StepStone Group, 137 Ventures, Terrain, Waybury Capital, and entrepreneur Elad Gil. New investors include Ribbit Capital, Google-backed CapitalG, Spark Capital, Bond, Lowercarbon Capital, Avenir Growth Capital, Glade Brook Capital Partners, Positive Sum and 1789 Capital Management.

Coupled with the new $1 billion round, Base Power has hauled in more than $1.27 billion in funding since it was founded in 2023.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”
