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.

This week, the U.S. Department of Energy announced that two Houston-based companies have won the American-Made Geothermal Manufacturing Prize — a $4.65 million competition to incentivize innovators to use 3D printing, or additive manufacturing, to address the challenges associated with operating sensitive equipment in harsh geothermal environments, per a press release. The competition challenged participants with quickly developing, testing, and revising prototypes using additive manufacturing to support the advancement of geothermal tools and technologies.

“This DOE competition harnesses breakthroughs in additive manufacturing to help overcome barriers to widespread deployment of geothermal energy,” says Alejandro Moreno, deputy assistant secretary for renewable power, in the release. “The rapid prototype development supported by this prize is spurring advancements in the geothermal industry to help power the nation from the heat beneath our feet.”

The competition launched in January 2020, and the finalists presented their innovations at the annual Geothermal Rising conference in Reno, Nevada. The winning teams each were awarded $500,000 in cash and up to $200,000 to test their innovations in the field. The two Houston-based winning teams were:

  • Team Downhole Emerging Technologies: "This team developed an alternative to traditional packer systems," the release states. "The all-metal, retrievable packer system is designed specifically for high temperatures, extreme pressures, and corrosion experienced in geothermal wells. The Downhole Emerging Technologies’ partnership resulted in the production of the largest Inconel additively manufactured component by Proto Labs, Inc. and the development of DET’s tool, the Diamond ETIP (Extreme Temperature Isolation Packer).”
  • Team Ultra-High Temperature Logging Tool: "This team developed a technology that uses a labyrinthian heat sink to reduce thermal emissivity and increase the exposure time of temperature sensitive electronic components," according to the release. "Oak Ridge National Laboratory used a powder bed laser fusion technique to manufacture the heat sink design, with the aim that the technology would solve limitations around maximum temperature rating and lifetime of electronics in logging and measurement tools. The team also worked closely with Sandia National Laboratories to test the logging prototype in a high-temperature setting."

Houston-based Koda Health has announced via LinkedIn that it has expanded into a handful of new states recently: Florida, Oregon, North Carolina, Virginia, California, and Maryland. These six expansions have all been announced over the past month following the announcement in July that the company is going nationwide.

"Every state has different regulations and requirements for their advancecare planning documents. So, the folks at Nixon Gwilt Law and Koda Health have been hard at work making our platform compliant in every single state," the company announced in a post. "It's hard work, but we're committed to helping patients stay in control of their health care journey, regardless of where they call home."

Koda Health was born out of the TMC's Biodesign Fellowship and launched by Tatiana Fofanova, Dr. Desh Mohan, and Katelin Cherry in March of 2020. The platform uses AI to help patients create advanced medical care directives and documents, such as a living will, through its proprietary machine learning approach.

In February, Koda closed over $3 million in seed funding in order to grow its staff and support expansion. Now, including Texas, Koda is in seven states across the country.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
