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.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
