When Houston Exponential established the HX Venture Fund, the goal was to bring out-of-town capital and investors into the city of Houston. The fund of funds invests in a portfolio of venture capital funds with the hope that those funds find a way back into the Houston startup ecosystem.

After a little over a year, HXVF has invested in five funds: Boston-based .406 Ventures, Austin-based Next Coast Ventures, Boston-based OpenView Venture Partners, Washington D.C.-based Updata Partners, and Austin-based LiveOak Venture Partners.

The fund of funds is also regularly hosting those five funds — as well as a mix of potential portfolio fund members — in Houston for what the HXVF calls "immersion days" where the venture capitalists can meet local startups, innovation leaders, and even fellow investors that they could eventually co-invest with.

"The goals of these days are to have venture capitalists travel to Houston, meet with our entrepreneurs (and the startup development organizations like Station, Cannon and WeWork that support them), and provide both capital and expertise in company building to the tech companies," says Sandy Guitar Wallis, managing partner at HXVF. "The venture capitalists also meet with HX Venture Fund corporate LPs, who can be customers or acquirers of their portfolio companies."

Just this month alone, HXVF is hosting four funds — two from their portfolio and two that they haven't yet invested in. San Antonio-based Active Capital, which has raised a $21 million fund, is among the visiting VCs this month. The fund's founder, Pat Matthews, an entrepreneur turned venture capitalist, has shared his busiest day — February 5 — as well as his perspective on Houston innovation with InnovationMap.

A morning too busy for breakfast

After waking up at the Hotel Derek, Matthews starts his second day in Houston by taking a Lyft to the Greater Houston Partnership for what he believes to be a breakfast meeting with Wallis and Guillermo Borda of HXVF, but the group has too much to discuss that a meal falls by the wayside.

Before this trip, Matthews hasn't visited Houston in a professional capacity. While Active Capital is based just down I10 in San Antonio, the firm's investments are split almost in half by deals done in Texas versus the rest of the world. Active Capital focuses on B2B SaaS investments — usually leading — in seed or series A rounds.

Matthews has called Texas home for around a decade. He founded an email marketing startup in Virginia, which was acquired by San Antonio-based Rackspace. He relocated to join Rackspace and worked on growing the organization for six years before creating Active Capital.

Following the meeting — still unfed, Matthews meets up with Serafina Lalany from Houston Exponential to carpool to The Cannon on the west side of town.

Loading up on carbs and fireside chats

Matthews forgoes his usual carb aversion to eat slices of Domino's pizza at The Cannon before beginning his first of three fireside chats with Houston innovators. Patrick Schneidau, CEO of Truss, leads the conversation at The Cannon. (Schneidau is a board member of InnovationMap's.) After the chat, Matthews has a meeting with a startup before heading back into town.

With one fireside chat down, Matthews heads into his second one of the day at Station Houston with Joe Alapat, founder of Liongard. Matthews observes that each of the entrepreneurs who interviewed him had great questions, and seemed to be far along with their companies. Meanwhile, any of the people he met before or after the chat seemed to be at a much earlier stage in their startup journey.

The last fireside chat was hosted by Rakesh Agrawal of Snapstream at WeWork's Jones Building location. Matthews and Agrawal attempted to set up a Facebook livestream for the conversation, but an issue with the technology wouldn't allow for the stream.

An evening of good food and great mentorship

With meetings and fireside chats done, Matthews heads straight to a dinner with Blair Garrou, founder and managing director of Mercury Fund. The two venture capitalists dine at Eunice and split several appetizers and a bottle of wine while discussing their own recent investments and interests. Matthews, who met Garrou in 2014, thinks of him as a great mentor in venture capital.

Matthews headed back to the hotel after dinner and crashes hard after the long day. He would head back to San Antonio on a Vonlane bus — he gets a lot of work done on his trips — the next day.

What's next for Active Capital and Houston?

Matthews says he left Houston with an overall positive opinion of the city, and says it's similar to other Texas cities, aside from Austin, in its startup presence and capacity. While he assumed he'd meet energy and space startups, he realized Houston had a lot more going on than that.

"It definitely seemed like there was a lot of passion and a lot of hustle," Matthews says. "And it seems like the city is really working to support and cultivate that and keep it in Houston. I was inspired."

Throughout the visit, Matthews handed out his business card and some conversations have developed from those connections, he says. Another representative from Active Capital who is focused on sourcing deals with startups will visit next, and Matthews says he also thinks that he'll return to Houston to continue conversations he's been having, including some with other investors.

"I could definitely see doing deals in Houston," Matthews tells InnovationMap.

Axiom Space expands executive team with two C-suite hires

new leaders

Fresh off officially making Texas its legal headquarters, Axiom Space has named two new C-level executives.

The Houston-based spacetech company, which is developing the first commercial space station, announced earlier this month that it had appointed Zach Gitomer as its new chief financial officer and Erick Wegerer as chief information officer.

Gitomer served as vice president of investor relations and capital markets for Axiom from March to June of this year. Before joining Axiom, he held various leadership roles at Bank of America, Merrill Lynch, and Citi, where he supported technology and growth companies, according to Axiom.

"Building era-defining space infrastructure and pioneering the orbital economy is a complex endeavor that requires not just an audacious vision and stellar engineering talent, but the financial infrastructure, discipline, and capital strategy to match," Gitomer shared in a LinkedIn post. "I’m honored to take on this role ... I’m looking forward to partnering with the exceptional leadership team here at Axiom Space during a defining chapter for the company and commercial spaceflight broadly, as well as a crucial period for maintaining U.S. human presence in low-Earth orbit and leadership in space exploration."

Wegerer joins Axiom after most recently serving as CIO of Washington-based Insitu Inc., a subsidiary of Boeing that develops customized unmanned hardware for commercial, government and defense customers.

"My time at Insitu was defined by talented people, meaningful challenges, and work that mattered. I'm grateful for the teams, partners, and leaders who made progress there possible. Stepping into Axiom, I'm energized by the mission, the momentum, and the opportunity to help shape what's next," Wegerer shared.

The duo was celebrated on the floor of the New York Stock Exchange last week.

“We are pleased to welcome these exceptional leaders to the Axiom Space team," Axiom CEO Jonathan Cirtain added in the announcement. “Their strong record of helping complex organizations advance their strategic priorities will strengthen our executive team to further advance our core business objectives."

It's been a busy summer for Axiom. The company tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million, in June.

It also announced plans to open a Japanese subsidiary July 1. It tapped veteran Japanese astronaut Koichi Wakata to lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. It also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

Axiom also officially redomiciled its legal headquarters from Delaware to Texas last month. Read more here.

Houston hardtech accelerator names 8 founders to 2026 cohort

hardtech fellows

Hardtech-focused organization Activate has named 50 new members to its 2026 cohort of scientists, which includes eight startups joining Activate Houston.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. Its fellows receive a living stipend, research and development funding, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

This year's fellows represent 41 companies from 22 U.S. cities and 11 states.

“This cohort clearly demonstrates that the next industry-defining companies won't choose between modern technology and deep science; they'll be built by combining both,” Cyrus Wadia, CEO of Activate, said in the announcement. “These are the scientists and engineers turning our most urgent global challenges into the companies that will deliver a more sustainable future.”

The Houston fellows are working across the energy, space, AI infrastructure and agriculture sectors. They include:

  • Sophie Clare Broun, founder of Anning Corporation, which is producing clean hydrogen by stimulating naturally occurring geologic deposits
  • Kathy Andersen, founder of Brint Tech, which builds optical sensing systems that quantify hydrogen for infrastructure operators
  • Dorsa Talebi, founder of Kinetiq Drive, which builds rare-earth-free, contact-free electric motors with wireless rotors for small appliances and heavy industry alike
  • Neethu Pottackal, founder of Nivera, which is developing natural, edible coatings made from agricultural byproducts to reduce food waste and extend the shelf life of fresh food
  • Jonathan Huffman, founder of Orbital Arc, which is shrinking spacecraft propulsion to a microchip powerful enough for deep space
  • Tim Lee, founder of Renesin, which develops advanced materials for faster, more efficient AI hardware
  • Joshua Livingston, founder of Selerra Separations, which is developing high-performance membranes that cut the cost and energy consumption of water treatment
  • Wenli Jiang, founder of SwieNitro Recovery, which is developing technology that converts nitrogen-rich waste streams into valuable fertilizer

"Home to the largest concentration of engineers in the United States and a dense ecosystem of Fortune 100 and Fortune 500 companies, Houston is uniquely positioned for scientists tackling large-scale industrial challenges. Activate Houston fellows are connected to the city's deep networks in energy, chemicals, and materials," Activate said in the announcement.

Activate named its inaugural Houston cohort in 2024. It has other hubs in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Nationally, it has supported 346 fellows and 276 companies since 2015.

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.
