Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston company closes $76M series C round to fuel its mission of reducing carbon emissions

money moves

A Houston-based company that is electrifying chemical manufacturing has closed its largest round of funding to date.

Syzygy Plasmonics closed a $76 million series C financing round led by New York-based Carbon Direct Capital. The round included participation from Aramco Ventures, Chevron Technology Ventures, LOTTE CHEMICAL, and Toyota Ventures. The company's existing investors joining the round included EVOK Innovations, The Engine, Equinor Ventures, Goose Capital, Horizons Ventures, Pan American Energy, and Sumitomo Corporation of Americas. According to a news release, Carbon Direct Capital will join Syzygy's board and serve as the series C director.

"We were very attracted to the multiple use cases for the Syzygy reactor and the lifetime-value of each Syzygy customer," says Jonathan Goldberg, Carbon Direct Capital's CEO, in the release. "Emissions from hydrogen production total more than 900 million metric tons of carbon dioxide per year. Syzygy's photocatalysis technology is a key solution to decarbonize hydrogen production as well as other critical industries."

Syzygy Plasmonics has a technology that harnesses the power of light to energize chemical reactions — rather than the traditional process that is fueled by heat. The Syzygy approach reduces feedstock waste and produces fewer emissions when powered by renewable electricity. According to the release, some series C participants have also formed commercial agreements to deploy Syzygy's technology to meet their decarbonization goals.

The investment funding raised will help the company to "further development and delivery of all-electric reactor systems that eliminate fossil-based combustion from chemical manufacturing and reduce the carbon intensity of hydrogen, methanol, and fuel," per the release.

"Our mission is to decarbonize chemical and fuel production," says Syzygy Plasmonics CEO and Co-Founder Trevor Best in the release. "Syzygy's aim is to achieve 1 gigaton of carbon emissions reductions by 2040, and the series C financing is a key milestone in building towards that goal.

"Closing this fundraising round with such strong support from financial and strategic investors and with commercial agreements in hand is a signal to the market," he continues. "Forward-thinking companies have moved beyond setting decarbonization goals to executing on them. Syzygy is unique in that we are developing low-cost, low-carbon solutions to offer across multiple industries."

Syzygy was founded based off a breakthrough discover out of Rice University from co-founders and professors Naomi Halas and Peter Nordlander, who invented high-performance photocatalysts. The company's collaborators then engineered a novel reactor that uses easy-to-find low-cost materials like glass, aluminum, and LEDs instead of high-cost metal alloys. After several field trials of the scalable, universal chemical reactor platform, Syzygy expects commercial units scheduled to ship in 2023.

"Syzygy is hyper-focused on aligning energy, technology, and sustainability," says Suman Khatiwada, CTO and co-founder of Syzygy, in the release. "The projects we are delivering are targeting zero-emissions hydrogen from green ammonia, low-emissions hydrogen from combustion-free steam methane reforming, and sustainable fuels made from carbon dioxide and methane. This technology is the future of chemical manufacturing."

Syzygy has raised a $23 million series B round last year following its $5.8 series A in 2019.

Report: These 10 jobs earn the biggest salary premiums in Texas

A move to Texas bolsters earnings for some, and a new SmartAsset study has revealed the top professions where the median annual earnings in the Lone Star State exceed the national median.

The report, "When it Pays to Work in Texas — and When It Doesn’t," published in April, analyzed over 700 occupations to determine which have the biggest "Texas premium" — meaning jobs where the price-adjusted median annual pay in Texas most exceeds the national median for the same occupation — and which jobs have the biggest “Texas penalty,” where the statewide median annual pay falls furthest below the national median. Salaries were sourced from the U.S. Bureau of Labor Statistics (BLS) and adjusted for regional price parity.

According to the report's findings, geoscientists have the biggest "Texas premium" and make a $159,903 median annual salary. Texas' salary for geoscientists is 61 percent higher than the national median for the same position (after adjusting for regional price parity).

"Texas’s large petroleum industry helps explain why employers in the state retain so many geoscientists," the report's author wrote. "In fact, the Lone Star State is home to more geoscientists than any other state except California."

There are more than 3,600 geoscientists working in Texas, SmartAsset said.

These are the remaining top 10 occupations with the biggest "Texas premiums" (salaries are price-adjusted):

  • No. 2 – Commercial pilots: $167,727 median Texas earnings; 37 percent higher than the national median
  • No. 3 – Sailors: $67,614 median Texas earnings; 36 percent higher than the national median
  • No. 4 – Aircraft structure assemblers: $83,519 median Texas earnings; 35 percent higher than the national median
  • No. 5 – Ship captains: $108,905 median Texas earnings; 27 percent higher than the national median
  • No. 6 – Nursing instructors (postsecondary): $100,484 median Texas earnings; 26 percent higher than the national median
  • No. 7 – Tax preparers: $63,321 median Texas earnings; 25 percent higher than the national median
  • No. 8 – Chemists: $104,241 median Texas earnings; 24 percent higher than the national median
  • No. 9 – Health instructors (postsecondary): $128,680 median Texas earnings; 22 percent higher than the national median
  • No. 10 – Engineering instructors (postsecondary): $129,030 median Texas earnings; 22 percent higher than the national media

The careers where Texas workers earn less

SmartAsset said an editor is the Texas profession where workers earn the furthest below the median for the same occupation elsewhere in the U.S. Not to be confused with film and video editors, BLS defines editors as those who "plan, coordinate, revise, or edit written material" and "may review proposals and drafts for possible publication."

The study found editors make a price-adjusted median wage of $29,710, which is 61 percent lower than the national median for the same position, and there are nearly 8,200 editors in Texas.

It's worth noting that the salaries for editors may be skewed by the fact that there are not major publications in rural areas of Texas, and other professions may also have financial deviations for similar reasons.

Several healthcare jobs also appear to have the worst penalties in Texas compared to elsewhere in the country. Home health aides are the second-worst paying professions in the state, making a median wage of $24,161.

"More home health aides work in Texas than in nearly any other state, with only California and New York employing more," the report said. "However, the more than 300,000 Texans in this occupation earn median annual pay that is about 31 percent below the national median, after adjusting for regional price parity.

SmartAsset clarified that pay penalties are not consistent "across the board" for other healthcare occupations in Texas.

"For physical therapy assistants, occupational therapy assistants, and postsecondary nursing instructors, Texas may be an especially strong place to work, with these occupations offering 'Texas premiums' of between 17 percent and 26 percent," the study said.

These are the remaining top 10 occupations where median annual earnings in Texas fall furthest below the national median for the same occupation:

  • No. 3 – Cardiovascular technicians: $49,382 median Texas earnings; 27 percent lower than the national median
  • No. 4 – Semiconductor processing technicians: $38,295 median Texas earnings; 25 percent lower than the national median
  • No. 5 – Tutors: $30,060 median Texas earnings; 25 percent lower than the national median
  • No. 6 – Control and valve installers: $56,496 median Texas earnings; 24 percent lower than the national median
  • No. 7 – Mental health social workers: $46,109 median Texas earnings; 23 percent lower than the national median
  • No. 8 – Clinical psychologists: $74,449 median Texas earnings; 22 percent lower than the national median
  • No. 9 – Producers/directors: $65,267 median Texas earnings; 22 percent lower than the national median
  • No. 10 – Interpreters/translators: $46,953 median Texas earnings; 21 percent lower than the national median

Houston rises in 2026 ranking of best U.S. cities to start a business

Best for Biz

Houston has reaffirmed its commitment to a business-friendly environment and now ranks as the 26th best large U.S. city for starting a business in 2026. The city jumped up eight places after ranking 34th last year.

WalletHub's annual report compared 100 U.S. cities based on 19 relevant metrics across three key dimensions: business environment, access to resources, and costs. Factors that were analyzed include five-year business survival rates, job growth comparisons from 2020 and 2024, population growth of working-age individuals aged 16-64, office space affordability, and more.

Florida cities locked out the top five best places in America for starting a new business: Tampa, Orlando, Jacksonville, Hialeah, and St. Petersburg.

Houston's business environment ranked as the 19th best in the country, and the city ranked 51st in the "business costs" category. However, the city lagged behind in the "access to resources" ranking, coming in at No. 72 overall. This category examined metrics such as Houston's working-age population growth, the share of college-educated individuals, financing accessibility, the prevalence of investors, venture investment amounts per capita, and more.

"From the Gold Rush and the Industrial Revolution to the Internet Age, periods of innovation have shaped our economy and driven major societal progress," the report's author wrote. "However, the past few years have been particularly challenging for business owners in the U.S., due to factors such as the COVID-19 pandemic, the Great Resignation and high inflation."

Earlier this year, WalletHub declared Texas the third-best state for starting a business in 2026, and several Houston-area cities have seen robust growth after being recognized among the best career hotspots in the U.S. Entrepreneurial praise has also been extended to five local companies that were named the most innovative companies in the world, and six powerhouse female innovators that made Inc. Magazine's 2026 Female Founders 500 list.

Texas cities with strong environments for new businesses
Multiple cities in the Dallas-Fort Worth Metroplex can claim bragging rights as the best Texas locales for starting a new business. Dallas ranked highest overall — appearing 11th nationally — and Irving landed a few spots behind in the 16th spot. Arlington (No. 23), Fort Worth (No. 30), Plano, (No. 35), and Garland (No. 65) followed behind.

Only six other Texas cities earned spots in the report: Austin (No. 24), Lubbock (No. 36), Corpus Christi (No. 39), San Antonio (No. 64), El Paso (No. 67), and Laredo (No. 76).

Austin tied with Boise, Idaho and Fresno, California for the highest average growth in the number of small businesses nationally, while Corpus Christi and Laredo topped a separate list of the U.S. cities with the most accessible financing.

Houston humanoid robotics startup taps Amazon veteran to lead manufacturing

new hire

Persona AI, a Houston-based startup that’s developing AI-powered humanoid robots for manufacturers and other businesses, has hired Brian Davis as head of global manufacturing.

Davis previously guided teams at Amazon Robotics and Dell Technologies. During his tenure at Amazon Robotics and Dell, both companies saw major increases in manufacturing volumes within a four-year period. Davis oversaw manufacturing, supply chain, logistics, quality assurance and real estate.

“Davis steps into this role [at Persona AI] as industrial enterprises face an urgent and accelerating challenge: a structural shortage of capacity for welding, fabrication, and heavy maintenance in dynamic environments, precisely the high-value, high-risk tasks where humanoid robots can deliver the greatest impact,” according to a company news release.

Davis comes aboard as Persona AI, founded in 2024, seeks to meet demand generated by deals with HD Hyundai and POSCO Group to make humanoids for shipyards and steel plants, and by a pilot program with the State of Louisiana.

“Now is the perfect time to accelerate our production capabilities as we rapidly close the gap between what’s possible in the lab versus what’s driving real commercial value,” Davis says.

“Building industrial-rated humanoid robots and production-deployable AI is only one piece of the puzzle,” he adds. “Producing humanoids at scale will require systematic supply chain management, stringent quality control, and building the playbook for safe, high-volume manufacturing. That’s what I’m here to build.”

Last year, Persona AI raised more than more than $10 million in pre-seed funding. The company also named a new head of commercial strategy in March.
