Greentown Labs has reshuffled its leadership, elevating Houston leaders into new roles.

Lawson Gow was named COO of the Houston- and Boston-based climatech incubator in February 2026. In his new role, he will focus on optimizing Greentown's structure, building new internal and external systems and developing a plan for growth.

Gow was named Head of Houston in July. He previously founded The Cannon, a coworking space with eight locations in the Houston area, with additional partner spaces. He also recently served as managing partner at Houston-based investment and advisory firm Helium Capital. Gow is the son of David Gow, founder of Energy Capital's parent company, Gow Media.

Kelsey Kearns, who previously served as Director of Community Strategy at Greentown, was named as Gow's replacement in the Houston-focused role. As the new Head of Houston, she will lead daily operations, work to connect the city's climate and innovation ecosystem and founders, strengthen partnerships and accelerate solutions.

"I'm honored and grateful to step into this new role," Kearns said in an email. "My goal is for Greentown to thrive so our founders can thrive! That means supporting their connection to the capital, pilots, and customers they need to grow while building partnerships across Houston's innovation ecosystem. I want Greentown Houston to become the playbook for every future Greentown expansion."

Before joining Greentown Houston, Kearns served as director of business development at Howdy.com, an Austin-based technology staffing company.

"Kelsey is such a perfect fit to lead Greentown Houston," Gow added in an email. "She's deeply passionate about the entrepreneurial community here and has worked throughout and across the ecosystem for years. She's built an awesome dream team here and has helped reinvigorate Greentown's presence and role in Houston's innovation economy."

Earlier this year, Greentown also named Julia Travaglini as the Head of its Boston incubator. Travaglini has held multiple leadership roles at Greentown since 2016. The organization named Georgina Campbell Flatter as its new CEO in early 2025.

Greentown Labs has partnered with Los Angeles-based software development firm Nominal to launch the new Industrial Center of Excellence at Greentown's Houston incubator.

Nominal will provide access to its connected test and operations stack to help engineers working at Greentown Houston startups boost their "efficiency, automation, and scalability," according to a news release. The news comes just a few days after Greentown announced a partnership with Houston-based EnergyTech Nexus, which will also open an investor lounge on-site.

"Our mission is to remove friction for innovative entrepreneurs, so they can rapidly scale their transformative solutions," Lawson Gow, Greentown's Head of Houston, said in the release. "The Industrial Center of Excellence with Nominal will complement Greentown's robust prototyping, equipment, and lab offerings to accelerate entrepreneurs' ability to bring disruptive technologies out of the lab and into the world."

According to Greentown and Nominal, the partnership will support startups that are focused on decarbonizing the manufacturing sector, which Greentown estimates represents about a third of startups in its Houston incubator.

The new center will host specialized workshops and Nominal will now offer weekly office hours for Greentown startups.

"The future belongs to teams who can deliver resilient hardware faster than anyone else," Bryce Strauss, co-founder of Nominal, added in the statement. "Competitive edge is defined by test velocity. Nominal is building a connected stack of software tools where every discipline works shoulder-to-shoulder to make confident, real-time decisions."

Nominal, which supports engineering work in the aerospace, energy, automotive and defense industries, closed a $75 million series B round this summer.

green team

Two of Houston’s leading energy transition organizations are joining forces.

Climatetech incubator Greentown Labs and founder community Energy Tech Nexus announced a "strategic ecosystem partnership," aimed at accelerating growth for clean energy startups. EnergyTech Nexus will move into Greentown Labs and plans to open an investor lounge on-site.

“Greentown Labs is the nexus for the energy transition, where startups can gather, collaborate and grow. Positioning our own extended community within the hallowed walls of Greentown will further foster the creation of authentic connections between founders and reduce friction to critical resources, bringing the village together will only accelerate the flywheel on innovation here in Houston, Texas,” Jason Ethier, EnergyTech Nexus founding partner, said in a news release.

Additionally, EnergyTech Nexus will launch Cephyron IRM, an AI-driven investor platform that will help founders of early-stage technologies connect with sources of capital. Greentown members will be granted early access to the platform.

According to the organizations, the ecosystem partnership represents years of collaboration. Ethier, whose startup Dynamo Micropower was one of the first to join Greentown's Cambridge, Massachusetts, incubator, previously served on Greentown's board of directors and in other leadership positions. He and Juliana Garaizar, a fellow founding partner of EnergyTech Nexus, were also instrumental in bringing Greentown Labs to Houston. Garaizar has also held numerous leadership roles at Greentown Houston.

“This partnership has been a long time coming—our organizations are kindred spirits that need to be working together to enhance the entrepreneurial support systems available to climate innovators in Houston,” Lawson Gow, Greentown’s Head of Houston, added in the release. “Capital is a top priority for climate and energy founders, and this team-up will directly address this challenge.”

Greentown Labs names first head of philanthropy

new hire

Greentown Labs has named its first-ever head of philanthropy in an "all hands on deck" move to advance philanthropic support for climatetech ventures.

Stacey Harris will join the clean energy incubator and brings more than 15 years of experience to the role, having led major partnerships at organizations like Make-A-Wish International, Movember, Net Impact and the Greater Phoenix Economic Council, according to a release from Greentown.

Harris will be based out of Greentown's Boston-area incubator but will support both its Texas and Massachusetts locations. Greentown maintains headquarters in Houston and Somerville, Massachusetts.

“Stacey brings national reach, local roots, and the entrepreneurial spirit we need,” Georgina Campbell Flatter, CEO of Greentown, said in the release. “She understands that philanthropy isn’t just about raising funds—it’s about building a movement, sustaining an ecosystem, and accelerating change together.”

In her new role, Harris will be tasked with designing and leading a philanthropic strategy that aligns with Greentown's corporate partnerships.

The incubator said in the release that Harris's hire is coming at a "pivotal moment," and the organization is "calling for all hands on deck" to support the clean energy space. "This includes inspiring states and local governments to lean in, individuals and family offices to step up, foundations to mobilize resources, and industry to invest boldly," the release states.

"Philanthropy has the unique power to accelerate innovation where it matters most—by backing the people and ideas that can change the world,” Harris added in the release. “At Greentown, I see an incredible opportunity to partner with local communities in Massachusetts and Texas, while also mobilizing catalytic funds that fuel entrepreneurs globally. I’m energized to work across donors, foundations, and industry to ensure these founders have what they need to go further, faster—together.”

Harris is the latest in a series of new hires for Greentown.

Lawson Gow, founder of The Cannon co-working space and former managing partner at Helium Capital, was named Greentown's Head of Houston in July. Flatter was also named as the organization's new CEO in February, after Naheed Malik was named its new CFO in January.

5. Texas data center proposed by U.S. Army could use more power than El Paso

The U.S. Army is proposing developing a gargantuan, 3-gigawatt data center complex on Fort Bliss property that within a few years would consume more electricity than all of El Paso Electric’s 460,000 customers combined – even as questions about its development, water usage and air pollution remain unanswered. If built, it would be the third major data center project in the El Paso region, along with Meta Platform’s $10 billion facility in Northeast and the $165 billion Project Jupiter campus that Oracle and OpenAI are building in Santa Teresa, New Mexico. The combined scale and size of the three facilities could quickly transform the Borderland into one of the nation’s core hubs of power generation and AI infrastructure. Continue reading.

Houston startup lands $1B from Blackstone and Halliburton, plans acquisition

power deal

Houston-based power generation startup VoltaGrid has nailed down a $1 billion equity investment from asset management heavyweight Blackstone and Houston-based oilfield services provider Halliburton.

The investment comes in two forms:

A $775 million primary capital raise
A $225 million secondary capital purchase from existing investors

VoltaGrid, founded in 2020, provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.

Aside from the $1 billion investment, VoltaGrid has agreed to buy Propell Energy Technology, a VoltaGrid supplier, for an undisclosed amount. Propell offers a natural gas power generation platform for AI data centers. VoltaGrid plans to add two manufacturing plants at Propell’s facilities in Granbury, a Dallas-Fort Worth suburb.

The investment and acquisition deals are expected to close in mid-2026.

Funds managed by Blackstone Tactical Opportunities are contributing to the $1 billion investment. William Nicholson, managing director of Blackstone, called VoltaGrid “a highly differentiated platform addressing one of the most important infrastructure needs of the AI era: reliable, rapidly deployable power. This investment is a strong example of Tac Opps’ focus on providing flexible, scaled capital to exceptional entrepreneurs and businesses operating in Blackstone’s highest-conviction investment themes.”

Nathan Ough, founder and CEO of VoltaGrid, said in a release that the Blackstone investment “is a powerful endorsement of the platform we have built and the role VoltaGrid is playing in delivering the energy infrastructure of the AI era.”

Last October, VoltaGrid and Halliburton said they had forged a partnership to supply power for data centers around the world, with the Middle East picked as the initial target. Two months later, the companies said they had arranged the manufacturing of 400 megawatts of natural gas power systems that’ll be delivered in 2028 to support new data centers in the Eastern Hemisphere.

Jeff Miller, president and CEO of Halliburton, said his company’s investment in VoltaGrid “reflects our shared focus on long-term solutions for the world’s most demanding power environments, and advances VoltaGrid’s ability to deliver reliable, distributed power at scale.”

Report shows geoscientists earn largest salary premium in Texas

Career Day

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 median
