When Sandy Guitar saw that Austin had a group of women in venture capital group that promoted collaboration and networking, she knew Houston had to have one too.

Guitar, who is the managing director of the HX Venture Fund, connected with the Austin group, picked their brains and asked for advice on starting a local iteration, and recruited a few fellow female VC experts in town — and the rest is history.

"There's a part of us as women that understands necessarily that work and life combine," Guitar says on this week's episode of the Houston Innovators Podcast. "Our lives as women don't allow us to segment our lives. The truth is those parts of our lives come together. The more we can do that, the more we can build networks that help us achieve everything we want both professionally and personally."

Now, over a year later, the Women Investing in VC in Houston group has grown to over 30 members — so much that their virtual visits are broken into smaller groups. The group boasts diversity and has representatives across types of funds. To join, women must simply live in Houston and be a venture capital investor. Other than that, the group is unstructured and casual, which fosters an environment where members are allowed to ask a stupid question or speak up on something personal, as Guitar says.

"When you have no dues and very little formality, no structure, no pressure to attend — it's in that setting that you actually build trust. Organically, the friendships come together," she says. "That's what it's really about."

While the group had pre-pandemic beginnings, the model of mentorship and networking is more relevant now than ever. Men and women alike, Guitar says, are not able to silo work and life as we work from home and practice social distancing.

"COVID has made us vulnerable in an entirely new set of ways," she says. "We use our support groups — whatever they are — to help us."

Guitar discusses the group and how what the venture capital industry needs to do to evolve into a more welcoming space for women in the episode of the podcast. You can listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Overheard: Experts discuss why Houston is the next hub for tech investing

eavesdropping in Houston

When Joe Alapat, co-founder and CEO of Liongard, was first getting started on his company, he says a few people recommended he go to Austin or one of the coasts to give his software company a better chance.

"For me, the thought process never really entered my mind that Houston was a place where I would be challenged in doing what I do well. My network is here," Alapat shared on a virtual panel hosted by the HX Venture Fund.

Turns out, it was a good decision. Liongard recently closed a $17 million series B round led by Updata Partners, a portfolio fund of HXVF. Moderated by Brian Richards of Accenture's Houston innovation hub, the panel asked Alapat, Sandy Guitar of HXVF, and Carter Griffin of Updata why Houston is the next hub for tech investing. Here are some key moments from the discussion.

“We’re cautious when we go into places — like Austin and Boston — where there’s a lot of activity both on the company side and the investor side. We’d rather find the opportunities where things aren’t as competitive and frothy, and you’re really dealing with people trying to build a real business, serve customers, and build value in the right way, and not just catch lightning in a bottle and build the next unicorn.”

—says Griffin about Updata's strategy of looking at cities like Houston in the middle of the country.

“A lot has changed in the past couple of years — the thought process, the awareness, as well as the willingness for folks to think about Houston as a place where you can build a startup.”

— says Alapat about how Houston's startup ecosystem has evolved since he started Liongard in 2015. He later notes that Houston's innovation leaders have done well to not copy other metros, but listen and learn from the successes and mistakes of other innovation cities.

“There was this feeling that we needed to be uniquely Houston — we couldn’t replicate Silicon Valley or Austin, we needed to be us. But we were going to have to do things differently. We couldn’t keep doing the same things and expecting this [change.]”

— Richard says, noting the corporate mindset, among other aspects of the ecosystem, shifted to be more focused on startups.

“The VCs are very interested in engaging in this model. So, we’re spoiled for choices is one way of saying it.”

— Guitar says on interest from venture funds in HXVF, noting that the VCs see an opportunity for their portfolio startups to connect with HXVF's corporate partners.

Houston's fund of funds expands its portfolio and team after reaching benchmark with local investment

money moves

When a Houston software startup closed a $17 million series B funding round, it was a big win for more than just the startup. Not only was the deal among the few Houston venture capital deals to happen amid the COVID-19 outbreak, but it represented a proof of concept for Houston's fund of funds.

The HX Venture Fund was founded in October of 2018 to encourage investment into local startups by raising corporate funds and investing into a portfolio of non-Houston venture capital funds that show an interest in Houston. HXVF hit a milestone last month when Liongard, a software-as-a-service company based in Houston, closed its fundraising round led by Updata Partners — one of HXVF's portfolio funds.

To date, the HXVF has reviewed over 150 venture capital funds and invested in eight: Austin-based LiveOak Venture Partners and Next Coast Ventures, Washington D.C.-based Updata Partners, Chicago-based Baird Capital, San Francisco-based VenBio, and Boston-based .406 Ventures, OpenView Venture Partners, and Material Impact Fund. Since each investment, those funds have invested in over 30 startups that are also included in the greater HXVF portfolio.

These HXVF portfolio funds represent various stages — from seed to growth stages, like Liongard — and across industries, from software and hardware to life sciences — "the whole gamut," says Sandy Guitar, managing director of HXVF.

"What that means now is there is over $2 billion of venture capital that actively has Houston on its radar right now," Guitar tells InnovationMap.

The Liongard investment represents a proof point for the fund of funds — one that comes earlier than expected. HXVF invested in Updata less than six months before Liongard closed its round with Updata's lead investment. Guitar says she expected to get to this milestone within 18 to 24 months of the fund of funds deploying capital — and it's happened in just nine months.

"You have this trickle down effect, where it can easily take two to three years to get your capital at work," Guitar says, explaining that HXVF first has to raise funds from its corporate partners, then vet and invest in the VCs, and, finally, wait to see how those funds invest.

Of course, the pandemic has not exactly helped the growth of Houston's startup and venture capital sectors. While COVID-19 has allowed growth in some sectors — telemedicine, for instance — it has limited the opportunities for startups to test the market.

"To build great startups, a startup has to do what I call 'run into walls.' They have to test the market, get it wrong, and pivot. The problem right now is there are no walls to run into," Guitar says. "You have to have an actively running economy and market for proof points of what's working and what's not working."

Meanwhile, Guitar observes, VC investors have limited their activity to their own networks due to the inability to meet face-to-face with unfamiliar startups. Comparing the VC-startup relationship to a marriage, you wouldn't meet and marry someone you've never met in person just like investors wouldn't fund an entrepreneur they have only ever met via Zoom.

"A lot of VCs are staying in their known networks in the short term," says Guitar, while, in the long term, VCs are going to rely on introductions to entrepreneurs from their network.

With this benchmark secured, HXVF is continuing to grow its portfolio — as well as its team. Recently, Guitar — who runs the fund with Guillermo Borda — brought on Houston native Aleece Hobson as venture partner.

"Aleece joining is a phenomenal step for us — a dedicated resource and venture partner on activation," says Guitar on the hire. "I think it speaks to the seriousness of purpose we have to make this not just an investment platform, but one that moves the needle on Houston."

Guitar says HXVF is also growing its limited partners with the addition of Rice University, which joins the likes of HEB, Shell, Chevron, and Houston Methodist — to name a few.

"We're going to be getting even closer to our limited partners' needs and introducing them to the 34 portfolio companies," Guitar says "and creating meaningful collisions between those two groups."

HX Venture Fund leader talks investment trends in Houston and plans for 2020

HOUSTON INNOVATORS PODCAST EPISODE 13

After 20 years in the venture capital world, Sandy Guitar Wallis has seen the evolution of investing — on both coasts and here in Houston as well.

Now, as managing director of the HX Venture Fund, Wallis is playing the long game. The fund of funds acts as a broker to other venture funds, raising money from limited partners and then strategically doling out investments to non-Houston venture funds, with the hope that those funds circle back into the Houston innovation ecosystem with a multiplier effect.

"We have raised a fund of funds with the HX Venture Fund, and we're deploying that capital across probably 10 venture capital funds over time," Wallis explains on the most recent episode of the Houston Innovators Podcast. "Each one of those funds, will invest in 15 to 20 underlying private companies. So, at the end of the day, HX Venture Fund 1 will have exposure to 10 VC funds, as an example, and — by virtue of those investments — maybe 300 private companies."

The HX Venture Fund is aiming to raise between $50 million and $70 million for its first fund. Last year, HXVF made six investments, and Wallis says she expects another three to five investments in 2020. Ultimately, Wallis says, HXVF is looking to get a wide range of of firms involved — from early stage to later, growth stages — as well as a diversity in industries of focus.

Beyond the money, HXVF is opening up the discussion on a national scale, with visiting VCs and potential investors.

"We are getting a lot of interest in coastal VCs who want to invest here," Wallis says on the podcast.

Wallis, who is a co-founder of Weathergage Capital, got her MBA at Northwestern University's Kellogg School of Management, but has been in Houston for most of her career — traveling to each coast for business. Wallis shares her expertise, discussing everything from why the IPO process has slowed to what startups need to know about venture capital.

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.
