The HX Venture Fund, which invests in out-of-town venture capital funds that have their eyes on Houston startups, has grown its portfolio.

The fund of funds now has a portfolio of 10 VCs from across the country, across industries, and across startup stages. According to a recent announcement, the HX Venture Fund has invested in New York-based Greycroft Venture Partners and Washington D.C.-based Revolution Ventures. The announcement also included Boston-based Material Impact and San Francisco-based venBio Global Strategic Fund, however those had been previously reported by InnovationMap.

"We are delighted to partner with the general partners of Greycroft Venture Partners, Material Impact, Revolution Ventures, and venBio Global Strategic Fund," says Sandy Guitar, managing director of HX Venture Fund, in the release. "With their proven expertise and exceptional track records, we are excited to integrate them into Houston networks and not only give them access to the Fund's innovative corporate limited partners, but also harness their knowledge to empower Houston entrepreneurs."

These four VC funds join six others that HXVF has invested in: Austin-based LiveOak Venture Partners and Next Coast Ventures, Washington D.C.-based Updata Partners, Chicago-based Baird Capital, and Boston-based .406 Ventures and OpenView Venture Partners.

"The receptivity of the HX Venture Fund model has exceeded all our expectations. Since early 2019, over 217 venture capital funds across the U.S. have expressed definitive interest in participating in our model," says Guillermo Borda, managing director of HX Venture Fund, in the release.

"It is especially noteworthy that collectively, the ten funds selected for HX Venture Fund's portfolio have $3.7 billion in committed capital in their funds to be invested with Houston on their investment radar," Borda adds. "This is at a time that provides compelling investment opportunities in the economic cycle. This is an exciting time for Houston entrepreneurs and our innovation ecosystem."

Guitar previously told InnovationMap that she's looking to curate a portfolio of VCs that is diverse in industries and stage. Additionally, before investing in a VC, the HX Venture Fund looks for an interest in investing into Houston startups. The hope is that, while not required, the HXVF portfolio funds invest in a Houston startup down the road. Earlier this year, Houston-based Liongard became the fund of funds' first example of that.

"The innovation and talent in Houston are best-in-class; we want to be investing there," says Tige Savage, managing partner at Revolution Ventures, in the release.

Houston digital health platform Koda lands strategic investment

money moves

Houston-based advance care planning platform Koda Health has added another investor to the lineup.

The company secured a strategic investment for an undisclosed amount from UPMC Enterprises, the commercialization arm of the University of Pittsburgh Medical Center. The funding is part of Koda's oversubscribed series A funding round that closed in October, according to a release.

"UPMC Enterprises’ investment is a meaningful signal, not just to Koda, but to the broader market," Dr. Desh Mohan, chief medical officer and co-founder of Koda Health, said in the news release. "It validates that health systems are ready to invest in infrastructure that makes advance care planning work the way it should: proactively, at scale, and with the human support that these conversations require. Having UPMC Enterprises as a strategic investor puts us in a unique position to prove what's possible."

Koda has raised $14 million to date, according to a representative from the company. Its series A round was led by Evidenced, with participation from Mudita Venture Partners, Techstars and the Texas Medical Center last year. At the time, the company said the funding would allow it to scale operations and expand engineering, clinical strategy and customer success. The company described the round as a "pivotal moment," as it had secured investments from influential leaders in the healthcare and venture capital space.

Koda Health, which was born out of the TMC's Biodesign Fellowship in 2020, saw major growth last year, as well, and now supports more than 1 million patients nationwide through partnerships with Cigna Healthcare, Privia Health, Guidehealth, Sentara, UPMC and Memorial Hermann Health System.

The company integrated its end-of-life care planning platform with Dallas-based Guidehealth in April 2025 and with Epic Systems in July 2025. It also won the 2025 Houston Innovation Award in the Health Tech Business category. Read more here.

New 'living pharmacy' biotech company launches out of Rice venture studio

fighting cancer

Rice University’s biotech venture studio RBL LLC has launched a new “living pharmacy” company, Duracyte, designed to make cancer treatment easier on patients.

Backed by an up to $45 million Advanced Research Projects Agency for Health (ARPA-H) award, Duracyte aims to commercialize implantable biohybrid pharmacy devices that are designed to produce therapeutic proteins inside the human body around the clock, replacing the need for regular injections and infusions for some cancer patients.

The company’s main platform is its Hybrid Advanced Molecular Manufacturing Regulator (HAMMR), a rechargeable, implantable device that can sense biological signals, monitor tumor environments and adjust therapeutic output in real time. HAMMR has wireless communication capabilities, which allow patients and clinicians to remotely monitor results through an app every five minutes and make changes to treatment plans without a hosptial visit. Additionally, the device can generate its own oxygen supply, which is key for the therapeutic cells’ survival.

“Biologic medicines such as monoclonal antibodies, cytokines and metabolic regulators already account for a significant share of modern therapeutics, but the way we deliver them today often requires frequent injections or infusions that can be demanding for patients and lead to inconsistent drug levels,” Daniel Anderson, MIT professor and co-founder of Duracyte, said in a news release. “Our vision is to enable a continuous, stable therapy by producing these medicines directly inside the body, which could improve treatment consistency, reduce side effects and ultimately transform how biologic therapies are delivered across many diseases.”

Duracyte’s first clinical trial is slated to begin by the end of 2026 and will focus on recurrent ovarian cancer. The Phase I study will build upon existing work on encapsulated cytokine pharmacy technology, and the company hopes that within a few years this treatment can reach clinical application.

The development of Duracyte is supported by ARPA-H's Targeted Hybrid Oncotherapeutic Regulation (THOR) project, which supports a multidisciplinary research consortium co-led by Omid Veiseh, a professor of bioengineering at Rice. The consortium also includes others at Rice, The University of Texas MD Anderson Cancer Center, Stanford University, Carnegie Mellon University, Northwestern University and the University of Houston, plus industry collaborators like Chicago-based CellTrans.

“What we are building is the culmination of years of progress in cell engineering, biomaterials and implantable device technology,” Veiseh added in the release. “By combining these advances with real-time sensing and adaptive drug delivery, we are working with the support of RBL to create a true ‘living pharmacy’ that can deliver continuous, precisely controlled biologic therapies and fundamentally change how these treatments reach patients.”

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. Duracyte is the third company launched by RBL, including Sentinel BioTherapeutics, a clinical-stage immunotherapy company developing localized cytokine therapies for solid tumors, and SteerBio, a regenerative medicine company targeting lymphedema.

“Duracyte exemplifies the kind of breakthrough that Houston’s ecosystem is built to produce,” Paul Wotton, managing partner of RBL LLC and co-founder of Duracyte, added in the release. “With world-class clinical infrastructure, exceptional engineering talent and initiatives like the Texas Biotech Task Force driving alignment across industry, investment and talent, this region is uniquely positioned to move the most ambitious ideas in medicine from concept to patient, faster than anywhere else.”
