Houston-based Bairitone Health has closed an oversubscribed seed round and achieved a regulatory milestone, the company tells InnovationMap.

The healthtech startup, which is developing solutions and technology for untreated obstructive sleep apnea (OSA), raised $2.4 million, says CEO and co-founder Meagan Pitcher, exceeding its $2 million goal.

New York-based Golden Seeds, which invests in female entrepreneurs, led the round. Houston-based South Loop Ventures also participated, as well as MALIAM, Impact Invest Her and additional angel, venture, syndicate and family office investors. The company previously raised a pre-seed round of $435,000 in 2024.

Pitcher says the latest funding will go toward Bairitone's clinical site expansion, FDA-facing work and the continued product development of its SOMNAR technology.

"What I’m most excited about is what this lets us do next: expand our clinical testing, work with more patients and physicians, and keep improving based on what we learn," Pitcher said in a LinkedIn post.

SOMNAR is the company's noninvasive diagnostic platform for sleep apnea airway assessment. The platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

SOMNAR received Breakthrough Device Designation from the Food and Drug Administration in April. It is currently for investigational use only and is still pending FDA clearance. The new designation aims to help speed up development, assessment and review for premarket approval for medical devices, according to the FDA. It will also give Bairitone more opportunities to interact directly with FDA experts to make the approval process more efficient.

Bairitone was founded in 2022 in the Texas Medical Center's Biodesign program by Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators.

The company was a finalist for the Houston Innovation Awards in 2025 and 2024.

$12M pharmaceutical manufacturing facility to be built in Sugar Land

coming soon

A nearly $12 million drug manufacturing facility is coming to Sugar Land.

City leaders in Sugar Land recently approved a $1.3 million performance-based incentive for DeliverIt Group, a Sugar Land-based provider of specialty pharmacy, infusion therapy and clinical care services, for the development of the 60,000-square-foot facility.

The facility, which will be registered with the U.S. Food and Drug Administration (FDA), will compound medication. The process of drug compounding combines, mixes or alters ingredients to create a medication tailored to a certain patient. A compounded drug is created when an FDA-approved drug can’t meet a patient’s needs.

The facility, which will employ 55 people, will expand DeliverIt’s offerings from specialty pharmacy and infusion services to advanced pharmaceutical manufacturing. In a press release, the City of Sugar Land says the facility reinforces the suburb’s status as a hub for life sciences and health care innovation.

DeliverIt, founded in 2010, already employs about 60 people.

The $1.3 million incentive, to be distributed over the course of 10 years, is being funded through the Sugar Land Development Corporation’s 4A sales tax program.

“The addition of a pharmaceutical manufacturing operation of this caliber reflects the type of targeted growth we want to see in Sugar Land,” Jennifer Alexander, business development manager for the City of Sugar Land, said in a news release. “Our focus on smart, strategic investment means supporting life sciences innovators in ways that maximize existing assets while driving long-term community prosperity.”

The current size of the U.S. drug-compounding market is estimated at $7.42 billion, and it’s projected to climb to $12.79 billion by 2035, according to Towards Healthcare Research and Consulting.

Drug compounding is gaining momentum due to increases in personalized medicine and personal treatment approaches, with growth being supported by aging populations and the rise of chronic illnesses, Towards Healthcare says.

New Houston biotech co. lands $30M for pulmonary fibrosis drug

drug money

Most of us can claim a scar or two on our bodies. But when scarring develops inside the body, it’s known as a fibrotic disorder. A freshly launched Houston company, Oorja Bio Inc., is working on a treatment that can help to repair cells and reduce the damage wrought by the growth of fibrotic tissue in patients.

Late last month, Oorja Bio hit the scene with a pair of big announcements. Not only has the company raised a $30 million Series A thanks to founding investor California-based Westlake BioPartners, but it has also already paved the way for a Phase 2 study to take place this year.

Oorja Bio received Investigational New Drug (IND) clearance from the U.S. Food and Drug Administration (FDA), allowing the company to test its treatment in patients with idiopathic pulmonary fibrosis (IPF), a scarring of the lung tissue. IPF affects more than 150,000 adults in the United States and can result in a range of symptoms from shortness of breath to organ failure and death as it progresses.

Oorja Bio’s lead drug candidate, ORJ-001, was shown in a Phase 1 in-human trial to demonstrate “therapeutically relevant exposure and favorable tolerability” in 64 healthy adult volunteers in whom it was administered daily or weekly, according to a news release. Pre-clinical studies of ORJ-001 showed durable target tissue engagement and biomarker activity in bleomycin-induced lung fibrosis.

Administered subcutaneously, ORJ-001 is intended to improve and even restore function in cells that can reduce the signaling that causes IPF. It stops advancement of IPF and also allows for tissue repair. Currently available treatments for the disease can slow the development of IPF down, but do not address the declining lung function that’s inherent in its progression.

“The clinical and preclinical results from our studies to date give us confidence that ORJ-001 represents a novel treatment approach with the potential to repair and reverse fibrosis and modify disease progression in IPF,” Dr. Janethe Pena, CMO of Oorja Bio, said in the release.

“Our team is energized to deliver on our goal of redefining the future of fibrotic diseases, beginning with ORJ-001,” CEO and founder Sujay Kango added. “As we advance ORJ-001 in the clinic, we are embracing the paradigm shift in our biological understanding of IPF pathology that aligns with the central role of the alveolar epithelium. ORJ-001 was designed with this biology in mind and may provide, for the first time, a therapeutic intervention that repairs and reverses fibrosis and promotes disease modification.”

Most patients live only three to five years following their IPF diagnosis. Soon, ORJ-001 and Oorja Bio could give them a fighting chance.

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.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
