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.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
