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.

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

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.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
