Impact Hub Houston — the local chapter of a nonprofit focused on supporting startups in the social impact space — has a lot on its plate this month.

Not only is next week The Houston Innovation Summit — the fourth annual week of entrepreneurship programming — as well as the second annual Climathon, but the organization has also just launched a new business incubator program.

Accelerate is a program that Impact Hub has offered across 17 international markets. Houston's new chapter already has a few Houston startups involved — including Potentia Workforce and McMac CX. Structured as an ongoing accelerator with mentorship, education, and support, the program is currently accepting new members.

"We actually sit down with each new Accelerate member and then go through a diagnostic interview to help them understand what stage they're at," says Grace Rodriquez, CEO and executive director of Houston Impact Hub. "And then we create a development strategy with them."

Whether the Accelerate member needs one-on-one mentorship, specialized education, or more, the program match makes each member's needs. EY is a network partner and — since everything is virtual — member companies have access to international experts through Impact Hub and its partners' networks.

"The ideal entrepreneur for the Accelerate membership is somebody who has already developed a solution — at least an MVP — for their social venture, whether it's a product or a service," Rodriguez says.

She cites Potentia as an example. The startup helps find jobs for adults with special needs, as well as educate corporations on how to work with and collaborate with these individuals. The company already has data and momentum, and the Accelerate program is helping the company to get to it's next stage.

"The idea is that we help people ladder up — no matter what stage you're at," Rodriguez says.

While growing the new program's membership — Rodriguez says it's her goal to get to 10 member companies my early next year — she's also focused on The Houston Innovation Summit and Impact Hub's Climathon.

The second annual Climathon, which begins Friday, November 13, has evolved since last year in a number of ways. First of all, it's completely virtual — which poses its own set of challenges and opportunities. Additionally, the event has several new partners — most of which didn't even exist in Houston last year, like Greentown Houston and Evolve Houston.

One of the biggest, most exciting changes for Rodriguez is the structure. While last year's event functioned as a hackathon, this year attendees can expect thought-provoking programming and collaboration.

"Last year, [Climathon] was directed at people who were more tech savvy," Rodriguez says. "What we found is people who are interested in climate action are a lot of times policy oriented or community activists and they don't know how they can plug into the tech space. It's more of an idea-a-thon. You don't have to develop a tech solution, but we can think about how we can activate more people for climate change."

Last year's Climathon took place during October. WIth it moving to November this year, it coincides with THIS, adding even more events to the week-long, impact-focused summit. THIS, which was designed to run alongside Global Entrepreneurship Week, also considers that week's themes, which are: education, ecosystems, inclusion, and policy.

"The focus on education and policy is really interesting to me — it's not just about tech and business anymore," Rodriguez says. "It's really about how we are supporting businesses in the face of the pandemic, climate change crises — floods, fires, hurricanes — the entire world is being affected by these crises. ... [We need to focus on] how we are making sure that people are aware of everything that's happening and how we can innovate solutions."

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

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.
