Emily Cisek had a mission when she founded The Postage. She wanted to make afterlife planning simpler — and she's taken one giant step toward that goal with the company's new app.

"What we wanted to do [with the app] is make it so easy to plan your life and the end of your life using one click — as easy as it was for posting and commenting on social media," explains Cisek. "People are so used to reflecting on those behaviors and clicking one button to add a picture ... we wanted to make it that simple."

Though The Postage's website had mobile functionality, the app includes the ability to record and upload content. Whether snapping a picture of their insurance policy or recording a video to share with loved ones, The Postage app allows users to capture photos and videos directly within the app. Click here to read more.

After a huge dip in business due to the pandemic, a Houston company focused on supporting innovative life science companies saw 12 months of unprecedented growth. Kevin Coker, CEO of Proxima Clinical Research, says that's not only a good sign for the future of his business — but also of the future of Houston's life science sector.

"We're a good barometer for what's happening not only locally but across the country," Coker says. "As Proxima has grown, it's really show how the Houston life science market is growing."

Coker shares more about Proxima's growth and Houston's potential of being a major life science hub on the episode. Click here to read more and stream the episode.

Sylvia Kampshoff has lofty goals for her company Kanthaka, a platform for connecting users to personal trainers across over a dozen cities. With the launch of a new $1 million crowdfunding raise, Kampshoff is one step closer to growing her business according to these goals.

"Our vision is to become Amazon for health & fitness and the go-to provider to live a longer, happier and healthier life," Kampshoff says. "We couldn't be more excited about this journey." Click here to read more.

Houston fitness tech startup launches $1M crowdfunding campaign

money moves

Calling all cardio lovers, yogis, and strength trainers alike — a Houston fitness platform is opening up investment opportunities through a new crowdfunding campaign.

Kanthaka, a Houston-based app that connects clients to personal trainers and yoga instructors on-demand, announced it will be launching a $1 million campaign through Republic, a crowdfunding platform. Kanthaka's users and trainers — or anyone interested — now have the option to become part owners in the company.

"We are very happy at Kanthaka to have been selected by Republic for their crowdfunding campaign," says Sylvia Kampshoff, founder and CEO of Kanthaka, in a press release. "I want our users as our evangelists.

"Since we started the company I've had clients reaching out wanting to invest but it was complicated — you had to be an accredited investor or VC," Kampshoff continues. "Now through this crowdfunding campaign, clients and trainers can participate in our journey."

According to the release, Republic, which is strategically partnered with Houston-based NextSeed, only accepts less than 1 percent of applicants interested in being funded on the platform. Kanthaka has reportedly raised over $850,000 from two venture capitalists and angels investors to date.

The company provides both live in-person and virtual sessions. Between March 2020 and March 2021, Kanthaka grew over 700 percent in sessions sold, per the release, and now, with the COVID-19 vaccines, the company is seeing a new spike in sessions.

"Our vision is to become Amazon for health & fitness and the go-to provider to live a longer, happier and healthier life," Kampshoff says in the release. "We couldn't be more excited about this journey."

Frustrated with the lack of ease in booking training sessions, Kampshoff launched Kanthaka in 2017 and has grown the company and expanded into 15 markets. Kanthaka participated in Austin-based accelerator Sputnik ATX.

Big-box gyms have the potential of being a breeding ground for the coronavirus, but smaller studios aren't immune from the disease's consequences either. While most fitness spots have closed to prevent the spread of COVID-19, Houston-based Kanthaka has been using tech to enable at-home exercise before it was the only option.

That's why the app's founder Sylvia Kampshoff says she saw a huge spike in numbers last week as things began to close. Kanthaka allows users to book personal training sessions to their home. The one-on-one interaction has become really popular in this time of social distancing, and Kampshoff say soon the app will go even further in their efforts allowing its personal trainers to give virtual one-on-one training.

Brittany Barreto is passionate about femtech, helping entrepreneurs, and, despite being from the Northeast, Houston. Barreto joined the Houston Innovators Podcast this week to discuss her passions and her use to the Houston innovation ecosystem as a former founder herself.

"I actually think Houston needs to figure out how to capitalize on these recycled founders and how to get them in more mentorship and leadership positions," Barreto says on the podcast. "We're in Houston, Texas, and the second question out of everyone's mouths is, 'How can I help you?'"

Houston on-demand fitness startup to launch virtual option for at-home exercise options

workout from home

Last week, Sylvia Kampshoff saw a spike in her sales — something very uncommon for companies at this time, unless they are selling hand sanitizer, face masks, or toilet paper.

Kampshoff's company isn't providing toiletries though. Houston-based Kanthaka is an on-demand personal trainer tool for users to book one-on-one sessions with fitness experts at their own homes. With the city of Houston announcing that all bars and restaurants close to patrons, fitness studios followed suit. And that for Kanthaka meant a rise in sessions bought in Houston, Austin, Denver, Chicago, or any of the fifteen cities the app has launched in.

While gyms might be closing, "people feel pretty safe about having people come into their home," Kampshoff says, "and on the other hand we are wanting to give more jobs to trainers who have lost their jobs."

Kanthaka now has two people on boarding new fitness professionals on the app, and trainers who are out of work because their gym closed can get in touch with Kanthaka about the opportunity.

This spike in sales is coming mostly from younger users — particularly those in their 20s — but usually, Kanthaka has about a third of its users in the 60 and up age group — a population of people most at-risk from the COVID-19, or coronavirus. With this in mind, Kampshoff started looking into non face-to-face options for people who aren't comfortable with in-home instruction.

Next week, Kampshoff will launch digital sessions on Kanthaka. The sessions will still be one-on-one, but virtual. They won't be any cheaper, but will still provide that individual, undivided attention from a professional trainer. Additionally, Kanthaka will host free group fitness broadcasts online, and some will even factor in kids who are also stuck inside without many options for activities.

In just one week, Kampshoff had to pivot and tap a third-party streaming provider for the new service, something she has been able to do thanks to Sputnik ATX, an Austin-based accelerator Kampshoff is a part of.

"They were the first ones to say, 'Hey you should go virtual,'" Kampshoff says. "We started talking about it for the first time on Friday."

Ultimately, Kampshoff hopes this pivot will allow people access to personal training, as well as provide work for fitness professionals during the uncertain times of the coronavirus outbreak.

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. Read the full story here.

Fitting in fitness

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."

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.
