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.

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
