There's stretch of sleek low rise office buildings in Palo Alto — referred to as Sandhill Road — that has long been the center of Silicon Valley (and the world’s) venture capital sector. An investor friend of mine told me recently that Sandhill Road is a ghost town these days, with the key partners at many of the Silicon Valley venture funds largely working from home or at their second homes.

That’s disappointing if true, but not surprising. Commuting sucks, and this business is a lot more far flung and global than it used to be. The venture capital business is always a wild and fun ride, focused on founders and the next big thing, with constant movement and alliances and partnerships.

I’ve been in these waves since I began investing during the dotcom boom in 2000, making the jump from private equity to venture capital in San Francisco at a fund behind Yellowpages.com and a few others, before co-leading a prior firm I founded in San Francisco doing seed investing and advising funds and investment arms of Macquarie Bank, ConocoPhillips, and Shell. We got in on the ground floor of cleantech and did well. This is my third major VC downcycle – there is always opportunity on both sides, and the more things change, the more they stay the same in venture capital. Hubs matter, because the business is heavily a critical mass of talent and capital business, with a power curve of outcomes. Cutthroat as venture capital and startups are, it is not private equity. You do need partners.

Houston has long lacked a center of gravity at all, let alone in tech. You might try rereading the 2001 Economist headline article “The Blob that Ate East Texas” for some humorous color on that score. But in tech, that’s changing.

Rice University’s Ion Houston innovation district project came out of some of the Greater Houston Partnership work a few years ago on how to get a serious tech hub going (I briefly served on the GHP affiliated Houston Technology Center board for Royal Dutch Shell during that revamp). After a slow start, Ion has begun to fill up with tech startups and bona fide check writing investors to go with the constant barrage of startup programming on its Ion Activation Floor and adjacent Greentown Labs incubation building.

Chevron Technology Ventures opened a guest office on day one on the third floor and Houston private equity and sometime crossover VC investor Ara Partners took early space with its headquarters in the building across the hall from them. Local fund of funds HX Venture Fund, which was created out of that GHP/HTC revamp and also puts on the Venture Houston Conference, moved in on the second floor.

Our fund, Energy Transition Ventures, was the first venture capital fund to move into the Ion when we launched in 2021, is located two doors down from HXVF. My partners and I made the call to make Houston our headquarters over Austin where my partner, Craig Lawrence, is located. He’s a former energy tech and solar executive who learned venture investing leading the successful cleantech effort at Accel Partners in Palo Alto. We are both Texas educated, Bay Area venture capital alums who are doing venture capital in Texas because it’s our home. Our third partner, Q Song, moved from Korea to the US, picking Houston over Austin and our Bay Area office to join us.

Houston was not the obvious choice – it still isn’t – I got nostalgia when driving through Austin and San Francisco in the last week seeing the sheer mass of tech and venture capital names to do business with, but doing things our own way is kind of our brand. We chose the Ion, because well, venture capital and startup life is a participation not a spectator sport, and if Houston was ever going to have a shot at being an investment hub, it needed an actual hub, and founders needed a place to go meet venture capitalists, and that won’t work if venture capitalists all work out of their homes or alone in some energy corridor or downtown high rise.

In our hallway of the Ion, you pass HX Venture Fund, Decarbonization Partners, Energy Transition Ventures, and WaterLens, a water testing startup which spun out of UT many years ago, all next door to each other at one end. And at the other end BP Ventures — with a newly added ExxonMobil venture capital team guest suite adjacent — next to water and energy pipeline corrosion detection software and hardware startup INGU, a Chevron Technology Ventures-backed startup, which is adjacent to one of Houston’s largest venture-backed SaaS companies, Liongard. That’s a half a dozen tech startup founders and a dozen investors across all stages in 125 feet.

I can count approximately 20 other startups in the building now, still heavily skewed to energy. Across the floor, Artemis Energy Partners and Veriten, run respectively by Houston energy fixtures Bobby Tudor and Maynard Holt two of the three Tudor Pickering Holt founders, have their offices, with Schlumberger and hydrogen software startup Velostics which just announced its seed round sandwiched in between. The co-founder of Tierra Climate, a Rice spinout that also just announced its seed round works out of the coworking, and Eigen Controls is building GHG detection equipment around the corner a few feet from an Edtech and medtech startup, and renewable energy services startup Clean Energy Services is headquartered a few feet from the entrance.

Since we moved in, GOOSE Capital, a Houston investment group launched out of Rice at the Rice Alliance Business Competition two decades ago, put its offices in the Ion Activation Floor, and you can quietly find their Managing Director Andrew Nicholson trooping up and down the stairs. BP Ventures then pulled the trigger in 2022 – and moved its US venture capital investing team HQ to the Ion — right down the hallway from us. Chad Bown who manages the US team is sitting in a phone booth 100 feet from me and Chris Spears is listening on pitches as I type this. And this month Decarbonization Partners, the climate growth fund of BlackRock and Temasek, opened its office next door to mine in between us and HX, with three investment professionals, led by David Hayes, formerly with BP Ventures. Aramco Ventures, now led by the former Energy Ventures US head Jim Sledzik, began weekly Friday morning office hours. Jim can often be grabbed for a casual chat on his way between meetings on a regular basis, as can Luis Alcoser or Kemal Anbarci who pop in and out of the Chevron Technology Ventures visiting offices on third floor, with Veriten, which just announced an investment fund, and now Artemis joining recently.

The Houston pool of high quality founders and startups has definitely improved as well – though we still don’t have the quantity or quality of teams needed for a healthy startup market. Blair Garrou from Mercury Fund was part of a recent panel for the Texas Venture Crawl at the Ion along with BP Ventures’ Ion based Grace Chan talking about why Houston, and he remarked that in their earlier funds, Mercury was 5 to 10 percent Houston startups, having to go far afield to fill up even one fund - but his recent fund is closer to 25 percent Houston based, as local team quality has improved.

Houston venture capital is two orders of magnitude smaller than the Bay Area – it’s about like writing an article asking whether Silicon Valley is the emerging Energy Corridor. But it’s nice to have coffee and beers with next door neighbors who are actually investing in, and founders who are actually running, venture backed businesses. Founders are learning that Houston’s venture investment and tech scene has an actual home these days, and is open for business.

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.
