Houston investor outlines how rare VCs are in Houston — and how to find them

guest column

As a venture capitalist and former startup founder living in Houston, I get asked a lot about the best way to find and connect with a venture capitalist in Houston. My usual advice is to start with a list, and reach out to everyone on that list. But no one has a comprehensive list. In fact, VCs are such a quiet bunch that I’ve yet to meet someone who personally knows everyone on this proverbial list.

So, I got together with a couple of VC friends of mine, and we put together our own Houston venture capitalist list.

There are, by our count, 11 active venture capital funds headquartered in Houston of any size and type, and outside of corporate venture capital and angel investors, there are 30 total venture capitalists running funds.

Houston has always been quite thin on the VC fund front. I’ve jokingly introduced myself for a while as “one of the 13 venture capitalists in Houston.”

Let’s put this scale in some brutal perspective. With 7.2 million people in the Greater Houston Metro Area, the odds of finding a partner level active venture capitalist in Houston is about 1 in 240,000, if you take a most expanded definition of venture capitalist that might come down to 1 in 100,000. We’re the fifth largest metropolitan area in the country with a tremendous economic engine; there is a ton of capital in Houston, but it’s residing in things like institutional fixed income and equities, real estate, wealth management, corporate, private equity, family office, energy and infrastructure Basically, mostly everywhere but in venture capital funds for tech startups.

By comparison, there are almost as many Fortune 500 CEOs in Houston — 24, by our count — as venture capitalists and fewer venture capitalists than Fortune 1000 CEOs, of which there are 43. That means running into a VC in the checkout line at HEB is about as rare as running into the CEO of CenterPoint, ConocoPhillips, or Academy. In fact, as there are 115 cities in the Greater Houston area, you are three times more likely to be a mayor in Greater Houston Area than a partner at an investor at a VC firm, and more likely to be a college or university president. While we’re at it, you’re 400 times more likely to be a lawyer, 250 times more likely to be a CPA, and over 650 times more likely to be a medical doctor.

Our 30 venture capitalists in the Greater Houston Area are spread across 20 firms and all major venture sectors and stages. Venture capitalist is defined for this list as a full time managing director or partner-level investment professional actively running a venture capital fund with limited partners, currently investing in new venture capital deals from their fund from seed to growth stage, and residing in the Greater Houston Metro area.

To get to 31 we added in a couple of people running venture set asides for PE funds, and a number who work from Houston for funds with no office here. We excluded CVCs, as the decision making is more corporate than individual and rarely includes the committed fund and carried interest structure that defines venture capital, and excluded professionals at angel networks, accelerators, and seed funds that provide investment, but don’t manage conventional venture capital funds, as well as PE funds that do the occasional venture deal. We might be able to triple the number if we include venture capitalists at any professional level, and add in those professionals at PE and angel and seed funds, and corporate venture capital teams who are actively investing. But we’ll get to those other sources of funding in the next list.

The 11 venture capital funds headquartered in Houston are: Mercury, Energy Transition Ventures (my fund), Montrose Lane (formerly called Cottonwood), Texas Medical Center Venture Fund, Artemis, New Climate Ventures, Fitz Gate Ventures, Curate Capital, Knightsgate Ventures, Amplo Ventures,and First Bight Ventures.

Another half a dozen firms have a partner level venture capital investor here, but are headquartered elsewhere: Energy Innovation Capital, Decarbonization Partners, 1984 Ventures, Altitude Ventures, Ascension Ventures, Moneta Ventures, and MKB & Co. Two others, CSL Ventures and SCF Partners, are local private equity funds with a venture capital partner in Houston and a dedicated allocation from a PE fund.

Culling these for partner or managing director level currently in Houston, in alphabetical order by first name, LinkedIn profile and all.

We may have missed a couple of VCs hiding in plain sight, as venture capital is a pretty dynamic business.

VCs are just rare. And yes, perhaps more rare in Houston than in California. Something less than 1 in 100 VCs in the country live in Houston. Across the US there are somewhere around 1,000 to 2,000 active venture capital firms, and maybe another 1,000 to 2,000 active US based CVCs — so, plus or minus maybe at most 4,000 to 5,000 currently active partner level venture capitalists in the country excluding CVC professionals (active VCs and VC funds are really hard to count).

Perhaps in the most stunning statistic, the 7,386 elected state legislators in the US today outnumber the total number of American venture capitalists. Luckily for startup founders, the venture capitalists are more likely to return your phone call.

Overheard: Here’s what these energy VCs think of the pandemic’s effect on the energy transition

eavesdropping online

In a lot of ways, venture capital firms are tasked with predicting the future. They put money into tech and business services that are going to disrupt the status quo, and energy VCs are tasked with taking bets on the energy transition.

At a virtual event as a part of the 18th annual Rice Alliance Energy Tech Venture Forum, which is taking place online this week, a group of panelists moderated by Sandy Guitar, managing partner at the HX Venture Fund, discussed how the pandemic has affected the energy transition. The group of experts talked about the future of work, decarbonization, and more.

If you missed the event, here are a few key moments from the discussion.

“The role of digitization is going to be huge. The pandemic really exacerbated just how far oil and gas had been behind in that.”

Sean Ebert, partner at Altira. Ebert explains that when times are good for energy companies, it's hard to get the attention of executives to introduce new technologies. Now, corporations are having to invest in tech that allows their employees to be mobile and remote.

“There’s never been a better time to invest in energy technology. … We are at a point where we can get the type of returns [we look for.]”

George Coyle, managing partner at Energy Innovation Capital. Coyle adds that he's seen the pandemic effect major growth opportunities in energy startups in his portfolio.

“What we have is a sense of urgency that didn’t exist 15 years ago. Public companies virtually all have a sustainability report and need to show some sort of progress."

Cory Steffek, managing director at Ara Partners. He adds, "I really think the opportunity in the near term is de-risking software or hardware technologies and showing people that you can construct assets where they can deploy substantial amounts of capital profitably. If you have that, from a returns standpoint, you have something that should generate significant yield."

“The part we have been focused on is how can you make the conventional more efficient, so energy-on-energy conversion is even better.”

Hossam Elbadawy, managing director at SCF Ventures and technology partner at SCF Partners. He's referring to the question of whether to prioritize new low-carbon innovations or to make conventional methods more sustainable. His observation is that the solution is going to be a hybrid of both.

“When we think about the future of work, we think about what are the capabilities going to be required in the future to be able to improve operations in the field today?”

Ricardo Angel, managing director and CEO of PIVA. Angel adds that, "a lot of activities might be replaced by AI," and he and his firm are thinking about how they can go about "developing the skills for the people who will be working with those tools."

Texas institute grants $12M to bring leading cancer researchers to Houston

cha-ching

Rice University has recruited a prominent Swedish cancer researcher thanks to a $6 million grant from the Cancer Prevention and Research Institute of Texas.

It’s among $68 million in research grants recently awarded by the state agency, and six recruitment grants totaling $16 million to bring leading cancer researchers to Texas.

A news release from the Cancer Prevention and Research Institute of Texas (CPRIT) describes Pernilla Wittung-Stafshede of the Chalmers University of Technology in Gothenburg, Sweden, as “an accomplished and highly gifted biophysical scientist tackling complicated biological questions regarding the role of metals and metal dysregulation in various diseases. She pioneered a new research field around the role of metal ions in the folding and function of metalloproteins.”

Metalloproteins account for nearly half of all proteins in biology, according to the National Institutes of Health. They “catalyze some of the most difficult and yet important functions in [nature], such as photosynthesis and water oxidation,” the federal agency says.

Wittung-Stafshede, a professor of chemical biology and life sciences at Chalmers, is a former professor at Rice.

Aside from the money for Wittung-Stafshede, Houston recruitment grants also went to:

  • University of Texas M.D. Anderson Cancer Center: $2 million to recruit Rosalie Griffin of the Mayo Clinic
  • Baylor College of Medicine: $2 million to recruit Dr. Nipun Verma of the Yale University School of Medicine
  • Baylor College of Medicine: $2 million to recruit Xin “Daniel” Gao of Harvard University and the Massachusetts Institute of Technology

In Houston, cancer research grants were given to:

  • Baylor College of Medicine: $7.8 million
  • M.D. Anderson Cancer Center: $20.7 million
  • Rice University: $ 1 million
  • University of Houston: $1.2 million
  • University of Texas Health Science Center at Houston: $4.5 million

“The awards … represent the depth and diversity of CPRIT funding for cancer research in Texas,” says Kristen Doyle, CEO of CPRIT. “These grants develop new approaches to preventing, diagnosing, treating, and surviving cancer for all Texans.”

2 Houston startups win big at SXSW 2025 pitch competition

winner, winner

Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs echoed that sentiment with a post on LinkedIn celebrating the win.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” the post read. "Today, that mission feels even stronger."

The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

Two other Houston companies were selected as finalists:

  • Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
  • Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.
