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."

Houston medical device startup releases positive clinical trial results

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.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
