Houston-based private equity firm Sallyport has raised $160 million for its first investment fund, exceeding the target amount by $10 million.

The Sallyport Partners Fund focuses primarily on investments in founder- and family-owned businesses, corporate carve-outs and startups in various industries.

The firm’s chairman, Doug Foshee, seeded the fund. He and managing partners Kyle Bethancourt and Ryan Howard started the firm in 2023.

“Sallyport Partners Fund was created to utilize the proven processes our team has developed over time to generate value for like-minded investors on a larger and more impactful scale,” Foshee says in a news release.

Investors in the Sallyport fund include entrepreneurs, business executives and influential Texas families. Aside from Foshee, names of the fund’s investors weren’t disclosed.

“We are deeply committed to working hand-in-hand with management teams to drive transformative growth and generate long-term value,” says Bethancourt. “Our operational capabilities are forged from decades of firsthand experience leading, investing in, and building thriving businesses from the ground up. We have a unique appreciation for the management team’s perspective because we’ve been in their shoes.”

Those shoes have covered some pretty impressive ground:

  • Foshee is former chairman, president, and CEO of Houston-based El Paso Corp., which owned and operated a 44,000-mile natural gas pipeline network. In 2012, El Paso merged with Houston-based pipeline company Kinder Morgan in a multibillion-dollar deal.
  • Before Sallyport, Bethancourt was a vice president in the credit division of Blackstone, an investment powerhouse with more than $1 trillion in assets under management. Earlier, he worked at D.E. Shaw & Co., a New York City-based hedge fund with more than $65 billion in assets under management.
  • Before Sallyport, Howard worked at Platform Partners, a Houston-based private equity firm. Earlier, he worked for the natural resources arm of investment banking giant Goldman Sachs.

Former NASA astronaut is investing in the future of the oil and gas industry

Featured Innovator

When Tim Kopra returned from space in 2009 after he served as flight engineer on NASA's Expedition 20, he was ready to transition into civilian life. The Army vet went to business school, received his MBA in 2013, and started thinking about his next steps here on earth.

That is, until he was called back by NASA to serve as flight engineer then commander of the ISS in Expedition 46/47. He landed in June of 2016 after spending a career total of 244 days in space.

The timing was right this time around for Kopra. A former classmate of his, Ernst Theodor Sack, had worked at a Riverstone Holdings for a decade and had realized the potential for funding smaller, more niche startups. Sack was ready to branch out on his own, and Kopra was looking for his next career opportunity too.

That's how the two partnered up to create Blue Bear Capital, an investment fund that invests in data-driven technology companies in the energy supply chain.

"You can think of it as Silicon Valley tech, IoT, analytics, machine learning, SaaS business models applied to oil and gas, wind, solar, and energy storage," Kopra says.

The energy industry has been known to be slow to adopt new technology, like analytics, machine learning, and the Internet of Things, Kopra says, but Blue Bear's goal is to find the startups creating cutting edge technology and help them gain a footing in the industry.

"In order to adopt new technology, our view is that it has to be able to demonstrate clear value proposition upfront — not something that promises to improve operations down the line. It needs to happen relatively quickly."

Blue Bear capital closed its fund in the fourth quarter of 2018 with a total of eight investments. Kopra spoke with InnovationMap on how he's merged his space career into a tech investment guru.

InnovationMap: What sort of experience do you bring in to your investment responsibilities from your Army and NASA days?

Tim Kopra: On face value, it may sound like an odd match, taking someone with a tech and operational background and putting them in venture, but quite frankly it feels very familiar to me because my career has really been focused on working on complex technology and operations with very small teams. It's not just a theoretical understanding of the technology, but understanding how to use the technology and how it works.

It's something that over time, when you work with different kinds of aircraft or experiments on the Space Station or the space suits we use on space walks or the robotics system we used, you really develop a strong sense of how we as humans are able to work with technology and improve the functions we have in our jobs. That's a valuable aspect I bring to the table.

There's the operational component too. You can have great technology, but if it's not well matched to its job and implementation, it's not going to have the ability to solve the problems it was intended for. Third component is with small teams. I've worked with teams of two to 10 to 30 to several hundred — you recognize the need for people to work more effectively together.

I was on the last couple of astronaut selection committees. Our most recent one was going through 18,300 and select 12. Our job during the last portion of the selection is interviewing the last 50 or so. Those people competing for those spots are rock solid when it comes to their technical background and operational experience. The one thing we were asking ourselves as the interview committee was, "Who'd you want to go camping with?" It's the matter of the kind of people you can spend time with and be effective with. When we look at companies to invest in, we are looking for good small teams like that.

IM: How has Houston's tech ecosystem changed throughout your career?

TK: When we started in January of 2017, we saw one conference every few months that was involved in innovation and new technology and its application in oil and gas. Whereas now, it's pretty much every month that there's a major event about applying new technology in the industry.

IM: So, how has the city been for you as an investor?

TK: Obviously, Houston is the center for traditional energy and oil and gas. One thing that has been notable over our journey is the increased involvement in corporate venture funds. And, then the number of startups — it's a growing number and there's plenty of room for growth when it comes to energy startups. We've definitely seen an improvement in the types of technology provided and the number of startups emerging.

IM: Do you feel like the relationship you have with corporate VCs is competitive or collaborative?

TK: I think that the environment for venture capital in Houston in particular is very collaborative. When it comes to the corporate VCs, we're aligned because often times they are looking for companies farther along and then secondly, we're happy to co-invest with corporate teams. There are plenty of deals to go around, and we think working together we can definitely succeed.

IM: What types of companies are you looking for?

TK: We consider companies that are early revenue companies. We focus on data-driven technology companies, but they need to have recurring commercial revenue, so not just pilots.

IM: What's next for Blue Bear?

TK: We recently closed the fund, and what that means is we need to deploy the capital. We've invested in eight companies and had one exit, which we are excited about.

What we try to do is find the absolute best in class within a sector in which we invest.

IM: What keeps you up at night, as it pertains to your business?

TK: It's a very dynamic world. We have to keep track of macro trends and understand where the market is going. That has everything to do from the price of oil to government incentives to what large companies are investing in. I wouldn't say that it keeps us awake at night, but there's so many facets of the business that can impact what we do — positively and negatively. But we are constantly keeping track of what's going on in the world and what's going on in our sector.

The one thing we are most focused on right now is maintaining deal flow that we've been able to achieve. Going through the thousand or so companies we have over the past couple of years has been an extremely arduous task, but it's necessary for us to be able to understand the market.

We need to be as diligent as we have been over the past couple years. It's a really exciting space to work in, and we just need to maintain that level of excitement.

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.
