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.

2 Houston suburbs rank among 10 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.
