As a busy lawyer who traveled heavily for work, Sylvia Kampshoff found her workouts were often overlooked as she went from city to city, a casualty of long hours and a busy schedule. And, even though she did have a membership to a national gym with privileges at any of its locations, she hated the feeling of always being sold something and disliked that both the trainers and managers she worked with took very little interest in her personal needs and fitness goals.

She wanted something that allowed her to exercise with someone on her own schedule, and with people who valued customer service. That's how the idea for Kanthaka was born.

The app uses location technology similar to that of ride sharing apps to allow users to book training sessions with certified personal trainers, all of whom are heavily vetted and background checked by Kampshoff and her team.

"Many trainers at gyms or who work privately aren't certified," she says. "And that was important to me, that we have professionals who understand training and the body. And making sure our clients felt safe was a huge priority for me. We interview every trainer personally to ensure they not only meet our standards but also share our goals."

App users can select a trainer who will lead them in a Pilates, yoga, boxing, general training, or a pre- or post-natal workout. They select their location, as well as the date and they want to schedule a session. They can book a single session for $42 for a 45-minute session or $50 for an hour session or purchase a package of six or 12 workouts. There's no long-term commitment — although Kampshoff says that some clients are asking for a monthly subscription option — and the process is designed to be easy and user friendly. Trainers will arrive at a client's home, office, or their preferred gym, providing the gym allows outside trainers to work there.

The app launched in Houston in 2017 and then in Austin this fall. Over the last year, Kampshoff — who left the legal profession to concentrate on Kanthaka's success — says she's learned a lot about the market and her own preconceptions.

"I figured it was going to be business travelers who used it, people who were like me when I was doing all that travel," she says. "But it turns out that we're seeing people use it who want to schedule a session just like any other appointment. Many of our clients are women, who value the rigorous vetting process we have for our trainers."

In addition to vetting the trainers and confirming their certifications with the National Academy for Sports Medicine or the American Council on Exercise, each trainer is reviewed by app users, to help others determine whether that person would be a good fit for their needs. Kanthaka allows users to "favorite" trainers, and book them again, and user testimonials tout Kanthaka's easy of use and great training team.

In addition to individual users who find the app via social media or internet searches, Kampshoff has developed partnerships with hotels and apartments around Houston. Kanthaka provides personal training services to guests at the Post Oak Hotel, and Hanover apartment properties list the app as a feature for its residents.

As she continues to grow the business and expand in other cities, Kampshoff is excited to see others buying into her concept of fitness.

"There is a culture behind Kanthaka. It's about health and fitness, but also achieving the lifestyle you want that allows you to feel better and live in a more positive way."

Houston DNA-based dating app expands nationwide, launches next funding round

From swiping to swabbing

Houston singles can find their perfect match — even if it's someone across the country. Houston-based Pheramor — a DNA-based dating app — is available for download in every state.

Brittany Barreto, Pheramor's co-founder and CEO, has a PhD in genetics from Baylor College of Medicine. She first had the idea in a genetics seminar when she was 18 and in college, but that was almost 10 years ago, and the market wasn't ready. Now, she says singles have swipe fatigue from the existing and ineffective dating apps, and it's also relatively normal now to send your spit in the mail thanks to 23AndMe.

Pheramor users download the app and request a test kit. After a few cheek swabs, they send it back to Barreto and her team and they identify 11 immune system genes and upload the data to the user's profile. The app then compares the genes to other users to give a compatibility score.

"The science behind attraction based on your DNA is that people are attracted to one another when their immune systems are different — opposites attract is biologically true," Barreto says. "When we were cavewomen and cavemen, we didn't know who was our uncle and who was our cousin, so we used our nose to figure out who is genetically diverse compared to us. If you're genetically diverse, then you're probably not my relative, and therefore we'd have healthier children."

Pheramor also calculates a social score based on a questionnaire or a data mine of a user's social media. The overall compatibility score uses both the DNA and social compatibility scores.

The app launched in Houston in March to a great reception of local singles, but, a few months later, Barreto realized nothing was holding them back from expanding nationwide.

"We surveyed our user base and asked them if they had highly compatible numbers with someone in, say, Chicago, would they want to know," Barreto says. "And something like 89 percent said yes."

Pheramor users are usually between 28 and 38, have good paying jobs, and are seeing commitment, Barreto says. Most of them travel around a lot already.

"We opened it up on September 7, and in 30 days we saw over 50 percent growth in our user base."

The company has zeroed in on a few key metros where advertising dollars go a long way for generating user downloads; Boston, New York, San Francisco, Los Angeles, and Miami have all been great markets for Pheramor.

With the user base growing, Barreto is focused on growing her team. Pheramor's current round of funding launched November 1, and with the capital raised, she hopes to be able to make the team's CFO and chief marketing officer both full time.

Pheramor is also working on using its custom algorithm as a resource to other existing dating services worldwide as well as for couples who want to see their compatibility score with their current partners.

"A long-term goal that's coming to fruition a lot faster than I thought is Pheramor being a leader in genetic testing for romance," Barreto says.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

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

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

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.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
