With a busy September just days away, the Houston innovation world has seen an uptick in news. Just in case you missed some, here are some short stories from Houston startups — funding, product launches, clinical trials, oh my.

TMC invests in Luma Health's recent $16 million round

Luma Health, a San Francisco-based startup and TMCx08 cohort member, has closed a $16 million Series B round. The Texas Medical Center contributed to the round, along with U.S. Venture Partners and Cisco. PeakSpan Capital lead the series.

The company has a text-first communication platform to ease and automate the provider-patient conversations. The money, per VentureBeat, will go toward scaling up business.

"As we've spent more time with patients, doctors, and healthcare teams across the country, we've seen the disconnect between patients and clinics — patients really struggle to connect with their clinic, and clinics struggle to simply get a hold of their patients," the companies founders write on their website. "The one consistent theme we've heard after now deploying Luma Health at over 300 clinics is: how can we make it easier for our patients to get started on their care journey and connect with us as they map their personal path to healing?"

Houston-based Trumbull Unmanned has provided its drone technology to ExxonMobil since 2014. Now, the major energy company is scaling up its involvement with the local company.

Trumbull was recently awarded a five-year Unmanned Aircraft Systems Agreement and now will expand drone data collection and inspections as part of a new contract.

"Trumbull is grateful to serve amazing clients. After conducting data collection and inspections for ExxonMobil in over 25 locations, we are excited to scale operations starting in the Americas," says Trumbull CEO Dyan Gibbens in a release. "We look forward to helping ExxonMobil integrate amazing safety, efficiency, and data-driven technology into their operations."

Houston-founded startup relocates to Austin

A company founded in Houston has moved its headquarters to Austin, according to reports. Spruce — formerly known as Apartment Butler — provides luxury services (like dry cleaning, cleaning, and pet services) to apartment complexes.

Founder Ben Johnson told InnovationMap last December that, even though he's raised two rounds of funding from Houston — a $2 million Seed and a $3 million Series A — it was tough to convince venture capital firms from Houston. Houston-based Mercury Fund and Austin-based Capital Factory contributed to both the company's rounds. Princeton, New Jersey-based Fitz Gate Ventures led the Series A round, and the Houston Angel Network contributed too.

"Every single VC I pitched to wanted to require us to move to Austin as a condition to our funding," Johnson tells InnovationMap in a previous article. "I wanted to grow this business in Houston. I thought I was going to have to move to Austin because there wasn't a VC for us here."

Spruce already has a presence in Austin. The company has its services in 35 Austin-area apartment complexes, per the Austin Business Journal, as well as having Austin-based employees. Earlier this year, Spruce expanded its services to Denver, representing the first out-of-state business for the company.

Houston anti-fungal fabric fashion line launches

Houston entrepreneur, Megan Eddings, was disappointed with the athleticwear industry. She couldn't find a company that prioritized ethical and sustainable designs that were made with a fabric that wouldn't hold on to that strong, unpleasant sweat smell. So, a chemist by trade, she made her own.

Now, after months and months of work, Eddings has launched her company and the fitness line, Accel Lifestyle. The products are made in the United States in ethical conditions and shipped in 100 percent biodegradable packaging without any plastics involved. The custom-designed fabric — called the Prema™ fabric, which is now patent pending in 120 countries — doesn't hold onto the stink from working out, meaning consumers will be less inclined to throw them away, preventing unnecessary textile waste.

"I founded Accel Lifestyle because, even though there are so many fitness apparel companies today, none of them hit all the boxes on my checklist. I wanted to support a fashionable fitness apparel company that has an ethical supply chain (no sweatshops), and a fabric that doesn't smell. What did I find? Absolutely nothing. And, I wanted to change that," says Eddings in a release. "With my science background and experience working in science labs at University of Virginia and Brown University, it took 2.5 years to create the fabric from scratch, using the most luxurious threads available and a trade secret protected science."

A Houston medical device company using nanomedicine has released early results in its clinical trials treating prostrate cancer. Nanospectra Biosciences Inc.'s AuroLase technology uses laser-excited gold-silica nanoparticles with various medical imaging tools to focally remove low to intermediate grade tumors within the prostate, according to its study outcomes published in Proceedings of the National Academy of Sciences.

"As the first ultra-focal therapy for prostate cancer, AuroLase has the potential to maximize treatment efficacy while minimizing side effects associated with surgery, radiation, and traditional focal therapies," says David Jorden, CEO of Nanospectra, in a news release. "We are encouraged by the clinical success of our feasibility study to date and look forward to the initiation, potentially next month, of the pivotal study with an expected cumulative treatment population of 100 subjects."

One of the company's co-founders, Naomi J. Halas, is a professor of biophysics at Rice University.

Canadian oil and gas company with a growing presence in Houston named finalist in World Oil awards

While Houston can't completely claim Canadian oil and gas data company Validere, the company, which has a growing presence in the Bayou City, has been named a finalist in a prestigious awards program.

Validere is a finalist in the World Oil Awards' best data management and application solution award. The company is up against technology from the likes of Schlumberger, Halliburton, Siemens, NOV, Baker Hughes, and more,

The company has created a software that allows for real-time data and both artificial and human intelligence insights to improve its clients' quality, trading, and logistics. The company's technology enhances the ability of oil and gas traders to make informed decisions, which currently are made based off unreliable product quality data. Annually, $2 trillion of product moves around the oil and gas industry, and Validere uses the Internet of Things to improve the current standard of decision making.

Of course, the energy capital of the world has been a major city for growth — something co-founder Nouman Ahmad tells InnovationMap in a previous interview.

"As we think about the long-term future of the business, Houston is one of the most important markets for us going forward," Ahmad says.

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.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

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.
