A Houston-based AI solutions consultancy has made changes to its C-suite. Dan Watkins is passing on the CEO baton to Angela Holmes, who has served on MDS's board and as COO. As Holmes moves into the top leadership position, Watkins will transition to chief strategy officer and maintain his role on the board of directors.

"Over the last three years, as COO and a member of the board of directors, Angela has been instrumental in MDS’s growth, especially in building MDS’s Strategy Consulting practice and UI/UX and Machine Learning Engineering capabilities," saus Watkins in a news release. "The magic at Mercury Data Science is all about the diverse team who have created a culture of excellence, trust and purpose with the goal of using AI/ML to solve some of the most important health and social problems facing the world today.

"Angela was instrumental in building our culture and customer base over the last three years and will do a great job taking the company to the next level," he continues.

Mercury Data Science was incubated and launched out of Houston-based VC firm Mercury Fund. MDS works with the Mercury portfolio companies as well other startups in the life sciences and health care space.

"It is an exciting time to lead Mercury Data Science as we advance the development of innovative data science platforms at the intersection of biology, behavior, and AI," says Holmes in the release. "I am particularly excited about the demand for our Ergo insights platform for life sciences, allowing scientists to aggregate a vast set of biomedical data to better inform decisions around drug development priorities.

"The increasing understanding of biology, accessibility of large data sets, and accelerating computational capabilities is creating a golden age of life science innovation," she adds.

A new report looked into compensation at startups across the country, and the Texas market fared pretty well overall. The report from Carta, a San Francisco, California-based technology company that specializes in capitalization table management and valuation software, factored in data using more than 127,000 employee records from startups that use Carta Total Comp, the premier compensation management platform for private companies.

"At Carta, we see it as our responsibility to share the insights that come from an unmatched amount of data about the private market," per the report. "That includes data on startup headcount, payroll and equity metrics, salary medians, and remote work."

The greater Houston area ranked No. 15 in the list, which lands it at the top of the third tier just ahead of Dallas. As the chart depicts, Houston has 88 percent of the compensation of the top market — which this year is a four-way tie between the San Francisco, New York, San Jose, and Seattle areas. Austin landed in the middle of the top tier, and San Antonio snuck into the bottom of the third tier. The full report with national trends is online.

According to a Facebook post from Deer Park Economic Development, Houston unicorn startup Axiom Space has leased a 146,000-square-foot space in what used to be a Fry's Electronics store in Webster. Reportedly, the new facility will house its engineering operations.

"Axiom's initial plans for the building are to support 400 employees, all assigned to engineering work on the Axiom Station, including development across all of its subsystems," reads the post from July 6. "The buildout will be able to accommodate up to 540 people. Axiom plans a move in late July or early August."

Axiom hasn't put out an official news release on this particular facility, but in May the company broke ground on its headquarters at Ellington Airport, the site of the Houston Spaceport. That campus just down the street will house employee offices, astronaut training, and mission control facilities, engineering development and testing labs, and a high bay production facility to house Axiom’s space station modules under construction, according to Axiom.

Baylor College of Medicine's Translational Research Institute for Space Health — along with its partners California Institute of Technology and Massachusetts Institute of Technology — announced the new fellowship cohort of postdoctoral researchers supported by the TRISH Academy of Bioastronautics who will receive funding and resources for further career growth for two years.

“Cultivating the next generation of space health researchers is one of our strategic goals,” says Dr. Dorit Donoviel, TRISH executive director and associate professor in Baylor’s Center for Space Medicine, in a news release. “We aim to prepare a diverse workforce from a variety of scientific backgrounds to help us solve the challenges facing space explorers on future missions to the Moon and beyond. We are thrilled to welcome this next batch of postdocs as they help bring us closer to that goal.”

These fellows join a cohort of more than 20 previously supported TRISH postdoctoral researchers.

"My career was launched with a fellowship from the National Space Biomedical Research Institute (NSBRI), the predecessor to TRISH, so I greatly appreciate the value of mentorship and community to those starting out in the field of space biomedical research,” says Dr. Jeffrey Willey, associate professor of radiation oncology at Wake Forest University School of Medicine, in the release.

This 2022 postdoctoral fellows and their research projects are:

  • Xu Cao —Identifying Genetic Factors in Radiation Injury with Pooled Single Cell Sequencing
  • Ashley Nemec-Bakk — The Use of Two New Ground-based Models of Deep Space Travel to Study the Role of Mitochondria and Oxidative Stress in Cardiovascular Effects

The The Carbon to Value Initiative is a multi-year collaboration between the Urban Future Lab at NYU Tandon School of Engineering, Greentown Labs, and Fraunhofer USA, which is supported by the New York State Energy Research and Development Authority. In its second year, the carbontech accelerator program has selected eight startups in partnership with Fluor Corporation, the initiative’s Year Two Cohort Champion.

With almost 100 applicants from about 20 countries, the C2V Initiative named the following startups to the program, per a release from Greentown:

  • Aluminum Technologies (New Orleans, U.S.) has developed Carbo-Chloride Reduction (CCR) aluminum manufacturing technology, which captures process CO2 and also reduces power consumption relative to conventional methods.
  • Carbon Upcycling Technologies (Calgary, Canada) utilizes point-source CO2 and mineralizes it with waste materials to create supplementary cementitious materials (SCMs) that can be used in building materials.
  • Carbonova Corp (Calgary, Canada) utilizes CO2 and methane as a feedstock to produce carbon nanofibers (CNF) that may be used in various fields such as transportation and buildings.
  • ecoLocked (Berlin, Germany) converts waste biomass into biochar to create admixes that can replace a share of the cement used in concrete manufacturing, and thus sequester carbon within buildings.
  • Full Cycle Bioplastics (San Jose, U.S.) has a patented bacteria-based technology that converts organic waste into Polyhydroxyalkanoate (PHA), a biopolymer that can be used to replace a wide range of oil-based plastic applications.
  • Lydian (Somerville, U.S.) develops an electro-thermal reactor technology that converts captured CO2 into fuels and chemicals.
  • Molecule Works (Richland, U.S.) develops a solid sorbent Direct Air Capture (DAC) system using a novel reactor and contactor configuration.
  • Osmoses (Boston, U.S.) develops polymers for gas separation, enabling membrane-based carbon capture applications.

“If we are to succeed in reaching carbon neutrality, then carbontech must play a critical role,” says Ryan Dings, COO and general counsel of Greentown Labs. “For carbontech to do so, we must convene entrepreneurs, market leaders, investors, and policymakers deeply committed to rapidly creating a carbontech ecosystem, which is what our efforts with the C2V Initiative represent and why we’re so proud to be working with this incredible group of partners.”

While the program and its cohort companies aren't based in Houston, Greentown's local presence and member companies will play a role in the initiative.

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.
