The Ion taps John Reale for startup and investor role

new hire

The Ion has named John "JR" Reale as its director for startups and investor engagement.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."

Houston-based startup secures fresh funding led by local investor to expand HVAC, plumbing platform

money moves

Houston-based SmartAC.com, which provides a customer loyalty management platform for contractors, has raised a follow-on round from Mercury Fund and other investors. The dollar amount of the round wasn’t disclosed.

An October filing with the U.S. Securities and Exchange Commission (SEC) indicates SmartAC.com planned to raise $8.2 million in venture capital. Of that sum, about $4 million had already been raised, the company reported, and nearly $4.2 million remained to be raised.

SmartAC.com's platform enables contractors in the HVAC and plumbing industries monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

“Growing a business in the trades is all about customer loyalty, and loyalty is driven by optimizing the customer’s experience,” Josh Teekell, founder and CEO of SmartAC.com, says in a news release. “SmartAC.com was built to perfect the experience of home comfort through data-driven insights that bring long-term value to homeowners and contractors alike.”

SmartAC.com says the new funding will enable expansion of its platform.

“Amid rising consumer demand for ‘smart home’ innovations, SmartAC.com is addressing a critical need for more sophistication in HVAC and plumbing through a technology-driven strategy,” says Heath Butler, a partner at Mercury Fund.

In 2020, SmartAC.com emerged from stealth mode and announced a $10 million series A round. The company raised a $22 million series B round in 2023.

Houston biotech startup selected to pitch at SXSW

austin bound

Houston biotech startup PHIOGEN is among 45 finalists that will present at this year’s SXSW Pitch showcase in Austin.

PHIOGEN is one of five food, nutrition, and health startups that will participate in the pitch competition, set for March 9 and 10. A panel of judges will listen to the pitches and then pick the winners. Since 2009, SXSW Pitch finalists have raised more than $23.2 billion in funding.

PHIOGEN has developed the world’s first biogenetics technology platform to harness the power of bacteriophages in the fight against serious drug-resistant infections. Bacteriophages — viruses that are found in bacterial cells — “are ubiquitous in the environment and are recognized as the most abundant biological agent on earth,” according to an article published in 2022 by StatPearls.

Founded in 2023, PHIOGEN is a spinoff of the Baylor College of Medicine’s TAILOR Labs. The startup, based at the Texas Medical Center’s Innovation Hub, has attracted more than $5 million in funding.

“Nothing about our treatments is fabricated; it boils down to creating natural environments that mimic real-life infections, driving biological changes to create ‘super phages’ against the superbugs,” Amanda Burkardt, CEO of PHIOGEN, said in 2023. “As a result, we receive high-performing phage fighters that are trained and ready to deliver safe and effective treatments for clinical applications.”

Professional services firm KPMG is the main sponsor of SXSW Pitch.

Six of this year’s SXSW Pitch judges are from Houston:

  • Heath Butler of Mercury Fund
  • Jesse Martinez of LSA Global
  • Trevor Purvis of the Houston Astros
  • Anu Puvvada of KPMG
  • Irene Tang of StartOut
  • Nate Thompson of HTX Sports Tech

“2024 is an exciting year for startups, and we are looking forward to showcasing these inspiring companies that are making waves in their respective industries and the world as a whole, as well as help connect them with the resources needed to continue advancing,” says Chris Valentine, producer of SXSW Pitch.

Houston experts: Diversity is key to venture capital success

force multiplying investments

Venture capital firms across the board have a goal of driving a return on their investments, but getting a good ROI and factoring in diversity and inclusion into the equation are not mutually exclusive.

In fact, on a panel at the HX Venture Fund's recent conference, Venture Houston, two investors focused on diversity and inclusion made the point that diversity is a key ingredient to successful investing. The panel, hosted by Michael Lipe, managing director at Insperity, consisted of Stephanie Campbell of The Artemis Fund and the Houston Angel Network and Heath Butler of Urban Capital Network and Mercury Fund.

"If you don't believe that diversity outperforms or that having diverse perspectives coming to the table helps your business outperform, then you probably have not been exposed to diverse thought," Campbell says on the panel.

And, as she continues, the proof is in the data "that diversity does outperform and can be a real force multiplier for your portfolio."

"In terms of returns, the Kauffman Fellows found that women-led teams generate 35 percent higher returns on investment than all-male-led teams," Campbell sites. "Pitchbook and All Raise found that women-led teams exit faster and at higher multiples than their all-male counterparts."

Butler recognizes that there's an emotional side of the discussion of diversity and inclusion — especially in this day and age — and that's nothing to disregard. But, he says, building onto that, VC is about discovering new opportunities — it's what VC funds' limited partners are expecting.

"From a more tangible perspective, we are in the business of finding untapped markets and opportunities to invest in and I believe our LPs expect us to leave no stone unturned," he says. "Ultimately you have to recognize that the hockey puck is moving in a direction where your LPs will require you to be looking under every stone to deliver a superior return."

Butler gives Mercury Fund as an example. At its founding, the team saw the middle of America as an untapped opportunity. The challenge is that investors tend to gravitate to ideas and people they know.

"So much of investing in early-stage innovation is intuitive, and investors will usually invest in what they know and resonates with them," Butler says. "But we have to recognize that there's a natural inefficiency in trying to relate intuitively to someone who's different from you."

The key is creating a team and mission with a clear intent and focus on measuring the impact. This goes down to hiring the right people with in your VC team as well as setting up a culture for diversity to succeed.

"If two hiring managers with similar needs," Butler says, "and one has a naturally inclusive mindset and the other feels pressure to meet a diversity quota — in the long run, which team will truly leverage and profit from a diverse perspective?"

Campbell says now is the time to invest in diversity — especially in Houston. During the pandemic, overall seed funding went up but funding for female founders reached a three-year low. Houston has a population doesn't have a racial majority — and that's what the entire country will look like in 2055, Campbell says.

"The opportunity we have in Houston to capitalize on diverse talent can really be a great opportunity to show the nation what can be done with that diverse talent pool," she says.

Houston also has an opportunity to support and invest in women or people of color who have been overlooked but have innovative solutions for society's most urgent problems.

"The more that we invest in diverse perspectives and diverse founders the more solutions, products, and services are going to come into the market for a broader populations and empower those economies to solve some of our deepest problems," Campbell says.

Both experts end on a call to action for their fellow investors: take inventory of the impact you have now and make intentional moves toward inclusion and equity — otherwise you're leaving money and talent on the table.

"If you don't have a diverse team, you don't have a diverse perspective, which means you have an incomplete perspective," Butler says. "You're missing out on opportunity to connect with people, purchasing power, and ultimately profits."

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.
