Adrianne Stone knows firsthand how lonely the startup founder journey is, so she set out to help create a community for founders when she started Bayou City Startups last year. Now, Stone shares on the Houston Innovators Podcast that her monthly happy hours attract over 50 attendees on average.

"Being the venture associate with Capital Factory in Houston, I'd seen what the Houston ecosystem had to offer. There were events — happy hours, coffee meet-ups, all these things," Stone says on the show. "But it was not just a casual networking event usually. I wanted a consistent community where I could show up and say, 'guys, I had the worst week,' to people who got where I was coming from and who could commensurate or lean in and help."

The next opportunity to network with Bayou City Startups is Tuesday, July 18, from 5 to 7 pm at Kirby Ice House. Read more.

When he was an internal medicine physician, Sarma Velamuri watched helplessly as a friend’s 22-year-old daughter lost her life to sepsis. He had to tell his friend that she would not be coming home.

“There are 300,000-plus people a year who die of sepsis,” says Velamuri. “It’s important that people understand it’s not just those who are most susceptible to infections.”

This fact is not only unfortunate, but preventable. And that’s why Velamuri, who describes himself as “a recovering hospitalist,” co-founded Luminare in 2014. A full-time CEO since 2017, Velamuri, who runs the company with co-founder and CTO Marcus Rydberg, is based in the TMC Innovation Factory. Read more.

Chances are, you've heard of 50 Cent — his 2003 album "Get Rich or Die Tryin'" was a soundtrack to many. But Curtis James Jackson III, 50 Cent's real name, has done a lot since gracing your radios. He moved to Houston in 2021 and founded the G-Unity Foundation. In May, he wrapped on the second year of the G-Unity Business Labs, a business development incubator for Houston Independent School District high schoolers.

"I’ve spent years donating my time and energy to communities in need. I started G-Unity to do the same—to give back to kids so they have it a little easier than I did," Jackson writes on the website. "Team building and entrepreneurship are skills I learned along the way, but they are so important to develop early. I look forward to G-Unity supporting programs that are doing the crucial work of teaching kids to excel at life."

Around 150 students participated, and the winners are splitting a $500,000 investment. Read more.

The 50 Cent-backed high school entrepreneurship program wrapped up its second year of operation after helping over 100 Houston-area students build their small business plans.

G-Unity Business Labs, sponsored by Curtis James Jackson III — better known as 50 Cent — and Horizon International Group, allowed participants to build their own small businesses from the ground up. This year's cohort featured a variety of businesses, from a Caribbean hot dog food truck to a financial literacy course on personal finance.

In its second year, the program encouraged innovation and taught business acumen to entrepreneurial-minded high school students, culminating in an opportunity to create their dream companies. During this 28 week entrepreneurial internship program, around 150 students from Madison, Worthing, Yates, Kashmere, Booker T. Washington, and Wheatley high schools learned how to transform an idea they were passionate about into a full fledged product they can pitch to investors.

The after-school program consists of three stages – the first 20 weeks are about getting familiar with business concepts and building connections with peers and teacher volunteers. The next eight weeks are spent in the incubation phase as students are split up into teams and local entrepreneurs lead lessons, helping them workshop their ideas into a fleshed out corporation, before finally the teams compete in Hustle Tank, where students pitch their ideas to a panel of celebrity and entrepreneurial judges. At the event in May, the panel included 50 Cent and Mattress Mack. The five winning teams are now eligible to split $500,000 in seed money for their companies.

Summer Reeves, VP of design of Umbridge, is in charge of managing the incubation phase and said she has noticed a significant shift in the ideas the student groups have come up with between the two cohorts of the program; the first year saw flashier tech pitches. But during the second year of the program, Reeves said the students sought to address issues they see in their day-to-day lives, including a group who worked to develop support services to aid formerly incarcerated individuals after they are released.

“This year, a lot of students were more on the practical side,” Reeves tells InnovationMap. “We actually had three teams that were focused on mental health apps which I think is a great example of what youth today are really focused on.”

Reeves started off as a mentor to four teams during the incubation phase of the program last year providing students with guidance on how to set up their business plans, create prototypes, and pitch their companies to investors. After three of her teams won the Hustle Tank competition previously, she took over planning the incubation phase and recruiting other local entrepreneurs to act as mentors.

“We give them recommendations on how to pitch and how to frame their pitch but they also have the ability to get creative so we had some students who did short skits — some that did raps and spoken word type things — lots of creativity,” Reeves says.

Patrice Allen, senior manager of G-Unity Business Labs, said they use the students’ individual strengths and creative thought processes to place them into their teams, including asking them in interviews at the beginning of the year to try to sell her a pen to understand their pitching process.

“That’s the question the students always remember,” Allen says. “‘Sell us this pen or pick something out and sell it to us.’ It’s the weirdest thing and they love it.”

In building the teams at each school, Allen worked with educators to make sure every team had students with a variety of communication and planning skills as well as financial awareness. But Allen felt students were most successful when they incorporated their personal interests into their product design. The first place team of Hustle Tank, Caribbean Hot Dog Boyz, was especially emblematic of this mindset as they combined one member's background of selling hotdogs with another’s Caribbean heritage to create a food truck that sells the unexpected combo of oxtail hotdogs.

“To actually taste the food that they prepared was phenomenal,” Allen says “I have never ever thought that oxtails on a hotdog would be good but everybody was floored.”

Elizabeth Martin, director of communications and marketing for Horizon who runs the behind the scenes of funding, said students from the winning teams are now working on solidifying their business plans to qualify for the funds from the G-Unity foundation to develop their companies. Martin also said 50 Cent will retain a relationship with these teams, acting with varying levels of involvement depending on his deal with the students as anything from a silent partner to an investor.

“They do not walk home with $500,000 in their back pocket,” Martin explains. “We are investing in (them) — not giving — it’s an investment.”

The future of this program is uncertain as the Texas Education Association’s takeover of HISD is still in its transition phase but Martin advised to keep a lookout for an ABC Nightline interview of 50 Cent discussing G-Unity Business Labs, which is expected to release soon.

"I’ve spent years donating my time and energy to communities in need. I started G-Unity to do the same—to give back to kids so they have it a little easier than I did," Jackson writes on the website. "Team building and entrepreneurship are skills I learned along the way, but they are so important to develop early. I look forward to G-Unity supporting programs that are doing the crucial work of teaching kids to excel at life.

Meet the innovator who's leveraging big tech to advance Houston's ecosystem equitably

HOUSTON INNOVATORS PODCAST EPISODE 188

At a glance, Rob Schapiro's resume might not make the most sense. A trained geologist with decades of experience in the energy sector, Schapiro made the move to Microsoft three years ago.

"I saw this disconnect between technology companies and energy companies — they didn't really speak the same language," he says on this week's episode of the Houston Innovators Podcast. "I thought I could help potentially solve this problem and work between the two as a sort of translator."

Now, as Microsoft’s Energy Acceleration Program director and site leader for the company’s Houston office, which is located in the Ion, Schapiro is deeply embedded in Houston's innovation ecosystem and is dedicated to helping advance Houston's role energy transition in a sustainable and equitable way.

Inspired by the murder of George Floyd, Schapiro says he sought out opportunities in his personal life to expand his contribution to the community as an ally, and he became a big brother in Big Brothers Big Sisters. Microsoft, too, is active in supporting the community through partnering with local organizations, including SUPERGirls SHINE Foundation, the G-Unity Foundation Inc., and more.

"This has been one of the most rewarding aspects of my job, that I've had the ability to leverage the might of Microsoft and my own privilege to have an impact on real people," Schapiro says. "Microsoft's mission is to empower every person and every organization on the planet to achieve more, and when you think about how you do that, it's really daunting. We realized that in order to do that, it's going to require a workforce that looks really different than it does today."

Microsoft knows too well the changing workforce, both from a diversity perspective and when it comes to artificial intelligence and other new technology. In its recent Work Trend Index report, the company found that, rather than being afraid of AI replacing jobs, the majority of the workforce is interested in applying AI to mundane tasks.

Schapiro shares more about his view of how AI will affect the workforce, plus what all the energy industry needs to focus on amid the energy transition, on the podcast. He also weighs in on how Houston's innovation ecosystem has evolved and where he hopes it's going.

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.
