When Ahmad Atwan decided he was going to launch a venture capital fund focused on early-stage energy transition startups, Houston was a no brainer. But while there are similar funds on each of the coasts, Atwan learned that VC Fuel's concept was going to be kind of niche for Houston.

"We're the only early stage climate tech or energy transition firm in Houston right now, which is really surprising," Atwan tells InnovationMap, explaining that the Bay Area is home to dozens of these funds and there are even more on the East Coast. "I'm hoping there'll be more (similar funds in Houston), but it's also kind of a nice position to be in."

Atwan shares more about VC Fuel and the $100 million fund, which he's still raising for while also investing in a few startups at the same time, in an interview with InnovationMap. He also discusses how his expertise as a former founder and former private equity investor with Morgan Stanley and BlackRock makes him an opportune value-add investor.

InnovationMap: Why did you decide to start VC fuel?

Ahmad Atwan: I decided to start VC fuel because I've been in the energy industry my entire career. I've been both an entrepreneur — I started two companies in the 2000s that I sold. One was a energy technology firm and one was a Brazilian ethanol company.

After that I was on the buy side buying pretty large private energy companies — anywhere from the size of $500 million to $2 billion. And over that whole time, energy was a very exciting industry and was growing very fast.

But as I saw climate change happening more rapidly and becoming more of a reality, and as I started looking and investing in some renewable energy sources, like wind and solar, I realized that's really where my passion was and what I wanted to do. And at the same time, the world was moving towards that as well, and investors really wanted to have exposure to new energy or energy transition areas.

IM: What are you looking for in potential investment opportunities?

AA: The areas that we focus on are all decarbonized and kind of all across the board, ranging from clean agriculture, hydrogen, carbon capture and storage or carbon capture and usage, to energy efficiency, clean industrial processes, and more. And I think these are areas that they right now comprise less than 2 percent of the global energy mix, but they're going to be north of 10, 15, 20 percent over time. So, these are high growth areas, and they are either lower, zero, or even negative emissions.

We're looking specifically for companies that we call seed stage or series A, generally, sometimes series B. So, they're companies that are relatively early in their development, but have some sort of commercial traction. And ones that are looking for not only a venture capital firm, but someone that can be their partner and help guide them and help them in certain areas, like raising their next round of funding, helping them get introduced to customers.

IM: With your experience, what do you feel like you bring to the table as a hands-on investor?

AA: I think in my decade-plus in private equity, when I was an investor on the boards of a company, I always tended to be one of the most involved in helping guide operations and working with senior management. And I think that's probably because I was a founder in the past, so I really identify with founders and I try to figure out with them what's the gap in their skillset or knowledge base that needs to be filled. Sometimes it's one that I can naturally help fill, which might be on the financial side or on the commercial side. And sometimes it's just bringing in other experts to help the company out.

But I think having been both on the founder and the private equity side, I think I empathize with the founder usually. And I would give this advice to all founders out there: the most important relationship they're going to have is with their lead venture capitalist, because that's going to be the defining relationship that helps them get to legitimacy in terms of the next round of funding. It's something that I kind of learned from friends in Silicon Valley. It's not only building the relationship for VC fuel — it's building a relationship with one of the individuals in our firm, whether it's me or one of my partners, and having them be really invested in the company.

IM: Why did you decide on Houston for VC Fuel's HQ?

AA: First of all, Houston is the undisputed energy capital of the world. So to me, especially when you're looking at energy transition sectors that have to work with the energy industry, it was a no brainer. For a lot of the technologies we deal with — like carbon capture — and the businesses we deal with, it's going to be essential for them to connect with the energy world.

I think a second reason, frankly, and I didn't realize this until we really got deep into the idea is that we're a little bit unique and we have a little bit of a competitive advantage. There are over 30 climate tech firms in the Bay Area, and there are a large number as well in New York and Boston. We're the only early stage climate tech or energy transition firm in Houston right now, which is really surprising. And I'm hoping there'll be more of those, but that's also kind of a nice position to be in because, as we see opportunities come out of the energy companies, and as we try to attract talent and grow, we think we have a pretty unique offering.

IM: What has being located in Greentown Houston meant for you?

AA: It's been fantastic. I think Houston did a great job of attracting Greentown here as the second location. Working out of here, we're able to interact in real time with everything from startup companies to major corporations. You get such a diverse set of people who are passionate about energy transition. It's actually already led to some opportunities to invest in, as well as to connect with some of the bigger companies that want to invest with us. It's been just a great coincidence that we launched here when Greentown opened. We'd much rather be here than any other type of working space. So, we're very excited.

IM: What keeps you up at night as it pertains to the energy transition?

AA: I would say the first thing is commercial adoption. All of our companies so far have great management teams — especially founders — and excellent technology, but there's that bridge to actually get the technology adopted by a customer. Sometimes you can have the best technology, and it just never happens. So, I'm keeping my eye on how much progress are we making with commercial customers. A lot of these are big companies — whether it's a waste management or a tech company, like a Microsoft — are getting into energy transition. Customer adoption in that area is a key metric for us.

The second big one — and this one's a little newer to me because I didn't face it as much in the past — is regulation. So many of the areas that we look at are going to have their economics determined by regulations that are literally being written right now. For example, the Cares Act the by the Biden administration is deciding things like what the level of tax credits will be for carbon capture. The carbon capture company we've invested in suddenly sees their projects become a lot more profitable if that figure is on the higher side. It's important to keep our ear to the ground on regulation and try to anticipate where it's going. That's why we have a couple people who are ex-Department of Energy on our advisory board because we like to have that skill set.

IM: What's next for VC Fuel?

AA: Our cadence of investing is that we invest in about one company every couple of months, which is pretty fast for a venture capital firm in energy transition. What's next is for our current companies to get to the next stage of evolution. There is one that I can't talk about specifically, but it might be getting sold to a really exciting buyer — and it's very good to have that kind of exit early on in a fund's life. And for the rest of our portfolio companies it's about continuing to get customers and next rounds of funding.

We've done a really good job of building a portfolio. That's not concentrated in any one area of energy transition. We will continue to look for a diverse set of companies that compliment each other, and that can help each other out. One area we continue to look at is not just the carbon capture, but also the carbon use space where you can turn carbon into something that's actually productive. Another area that we continue to look at is the electric vehicle space, but not just traditional EVs, but the next generation EV technology.

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.
