RBL LLC, which supports commercialization for ventures formed at the Rice University Biotech Launch Pad, has secured an investment from Houston-based Modi Ventures.

Additionally, RBL announced that it has named Sahir Ali, founder and general partner of Modi Ventures, to its board of directors.

Modi Ventures invests in biotech companies that are working to advance diagnostics, engineered therapeutics and AI-driven drug discovery. The firm has $134 million under management after closing an oversubscribed round this summer.

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. William McKeon, president and CEO of the TMC, previously called the launch of RBL a “critical step forward” for Houston’s life sciences ecosystem.

“RBL is dedicated to building companies focused on pioneering and intelligent bioelectronic therapeutics,” Ali said in a LinkedIn post. “This partnership strengthens the Houston biotech ecosystem and accelerates the transition of groundbreaking lab discoveries into impactful therapies.”

Ali will join board members like managing partner Paul Wotton, Rice bioengineering professor Omid Veiseh, scientist and partner at KdT Ventures Rima Chakrabarti, Rice alum John Jaggers, CEO of Arbor Biotechnologies Devyn Smith, and veteran executive in the life sciences sector James Watson.

Ali has led transformative work and built companies across AI, cloud computing and precision medicine. Ali also serves on the board of directors of the Drug Information Association, which helps to collaborate in drug, device and diagnostics developments.

“This investment by Modi Ventures will be instrumental to RBL’s growth as it reinforces confidence in our venture creation model and accelerates our ability to develop successful biotech startups,” Wotton said in the announcement. "Sahir’s addition to the board will also amplify this collaboration with Modi. His strategic counsel and deep understanding of field-defining technologies will be invaluable as we continue to grow and deliver on our mission.”

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.

Rice University opens biotech venture studio in TMC

rapidly scaling

In its mission to amplify and advance biotech innovation, Rice University has announced its latest initiative — a new lab focused on bringing life-saving medical technologies to commercialization.

Established to rapidly build companies based on Rice University's portfolio of over 100 patents, RBL LLC is a new biotech venture creation studio based in Texas Medical Center Helix Park. RBL comes on the heels of establishing the Rice Biotech Launch Pad, a biotech innovation accelerator that opened last year.

Paul Wotton, executive director of the Rice Biotech Launch Pad, co-founded RBL with his colleagues Omid Veiseh, Rice professor of bioengineering and faculty director of the Rice Biotech Launch Pad; Jacob Robinson, Rice professor of electrical and computer engineering; and Dr. Rima Chakrabarti, a physician scientist and venture capital investor with KdT Ventures.

“This is a pivotal moment for Houston and beyond,” Wotton, who serves as RBL’s managing partner, says in a news release from Rice. “Houston has rapidly emerged as a global life sciences powerhouse, blending cutting-edge research with early clinical applications at Rice and the city’s world-renowned hospital systems.

"Investors from across the nation are recognizing Houston’s potential, and with RBL, we’re building on that momentum," he continues. "We’ll not only amplify the work of the Rice Biotech Launch Pad but expand our reach across Texas, creating opportunities for biotech ventures statewide and driving growth for the biotech industry as a whole.”

Strategically located in TMC, RBL will collaborate with medical leaders, investors, corporations, and other players both in the same building and on the greater TMC campus.

“Leveraging Rice University’s Biotech Launch Pad breakthroughs and pairing it with the world-class translational infrastructure of TMC Helix Park well positions RBL to drive unprecedented advances in patient care,” William McKeon, president and CEO of the TMC, says in the release. “This partnership between academia, industry and health care is exactly what’s needed to transform medical discoveries into real-world solutions that improve lives globally.”

RBL is Rice's latest effort to bridge the gap between academia and biotech innovation, an effort led by Paul Cherukuri, Rice’s chief innovation officer, who reportedly spearheaded development of the new initiative.

“RBL is a game-changer for Rice, Houston and the global biotech community,” Cherukuri adds. “This venture not only accelerates the commercialization of our innovations but also sets a blueprint for other universities looking to maximize the real-world impact of their discoveries. By combining scientific expertise with entrepreneurial support from Day Zero together with strategic clinical partnerships in the TMC, we’re creating a model for driving large-scale biotech innovation that universities everywhere should aspire to replicate.”

Since the Rice Biotech Launch Pad was established, Motif Neurotech closed its series A round with an oversubscribed $18.75 million, the hub secured a $34.9 million grant, and a “living pharmacy” founded at the Launch Pad received industry validation.

“RBL provides a powerful platform to translate high-impact scientific discoveries into therapies that will dramatically improve patient outcomes,” Veiseh says. “Our goal is to rapidly bring Rice’s pioneering research into the clinic, delivering life-saving solutions to patients around the world.”

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
