Angel investors, corporate venture, and more options for Houston startups outside of the traditional venture capital model.

In my last column about tapping into Houston's venture capital ecosystem, I identified the 31 venture capitalists in Houston. By most measures Houston is around 0.5 to 1 percent of US venture capital activity, and that low volume is reflected in the limited number of venture capitalists locally.

But outside of venture capital funds, founders often pull money from other places including angel investors, seed funds and corporate venture capital arms as well as cross-over investors. I got asked this morning by a founder at the Ion, where’s the rest of the list?

Houston has five active corporate venture capital funds, or CVCs, with at least one senior investment professional in Houston with and one with headquarters here (Chevron). A short list of the key investment professionals in the group includes:

There are maybe half a dozen other corporates In Houston that organize around a fund structure and governance of some type, and have been actively investing in venture capital rounds with professionals in Houston. Equinor, a long time corporate investor, Baker Hughes which relaunched a CVC effort in 2021, Mitsubishi has investment professionals in Houston, and Williams which launched a new CVC effort in 2022, as well as Occidental, BHP, and Waste Management which had active CVC efforts in the past that have gone a bit on ice, as did ConocoPhillips, P66 and Schlumberger. Two larger private equity funds Ara Partners and Quantum are active in venture capital deals, but in a more mixed model. This universe would probably add another 30 to 40 Houston based active investment professionals.

The city also has around 10 angel networks, pre-seed funds, pre-seed investors, and accelerators that write checks, typically in the $100K to $1 million range, but either without committed venture funds in an acceleration model, at varying degrees of active, scale, model, and type.

Layering them in no particular order the Houston universe expands by another dozen full time or mostly full time professionals, and a few dozen angels. I’ve included their main contacts below:

These are certainly not large numbers for a city our size, and commensurate with the size of the Houston startup market. But while the cupboard may be a bit bare, it’s not empty. As a founder chasing money, that’s about 75 to 100 names to go chase, with probably double that in active or semi-active angel investors investing through these pools.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
