Sixty organizations across the country have received a grant from the United States Department of Commerce — and one recipient is based in Houston.

Greentown Labs, dual located in Houston and Somerville, Massachusetts, has received a grant from the 10th cohort of the Economic Development Administration's “Build to Scale” program for its Houston location. The $53 million of funding was awarded to 60 organizations across 36 states, the District of Columbia, and Puerto Rico. All of the programs support technology entrepreneurs across industries.

“The Biden-Harris Administration is Investing in America to help create entrepreneurial ecosystems across the country and put quality, 21st century job opportunities in people’s backyards,” Secretary of Commerce Gina Raimondo says in the press release. “The ‘Build to Scale’ program will unlock innovation potential in regions all over the nation, improving our economic competitiveness now, and for decades to come.”

According to the EDA, Greentown, located in a growing innovation district, will receive $400,000 with a $400,000 local match confirmed. The project, named Houston Ion District Investor Activation, is described as a way to create economic opportunity through equitable capital access.

"This project capitalizes on the need for jobs and economic development, especially in communities most vulnerable to the impacts of natural disasters," reads the project abstract. "EDA funding will enable the expansion of Greentown’s Investor Program into EDIJ, in partnership with the Ion, to further climate equity and resilience in Houston and empower underrepresented entrepreneurs as the city transitions from fossil fuels to a clean energy economy."

Greentown receives of of the 2023 Capital Challenge Grant Recipients. The other competition, the Venture Challenge, also awarded funding to another Houston organization. The Urban Partnerships Community Development Corporation received $741,925 to support the BioWell Start Accelerator Program, which is committed to scaling of bio-industrial startups.

“EDA is proud to partner with this year’s ‘Build to Scale’ grantees as they fuel regional innovation hubs and technology-based economic development strategies throughout the U.S.,” Assistant Secretary of Commerce for Economic Development Alejandra Y. Castillo says in the release. “Investing in scalable startups and expanding access entrepreneurial capital will yield good-paying jobs, economic resiliency, and equitable growth in communities throughout America.”

The Ion receives $1.5M economic development grant to go toward Houston accelerator programs

accelerating accelerators

The Ion — a rising hub for innovation being developed in Midtown by Rice Management Company — has received a $1.5 million grant to go toward supporting its startup accelerator programs.

The grant from the Economic Development Administration is a part of the organization's Build to Scale (B2S) program and will also benefit three accelerators: the Ion Smart and Resilient Cities Accelerator, the Rice Alliance Clean Energy Accelerator, and DivInc Accelerator.

"Receiving this grant is a big win for our city — furthering the Ion's opportunity to bring together leading minds to solve some of our toughest challenges," says Brad Burke, managing director of the Rice Alliance, in a news release from Rice. "We believe that it's a fully collaborative approach that will lead to accelerating energy innovation and sustainable solutions."

All three of these accelerators will be represented in The Ion's Accelerator Hub and will work in collaboration, according to the release, in The Ion, which is expected to open in 2021 with cohorts set to open applications in early 2021.

"We are really excited about working together with DivInc and the Rice Alliance for Technology and Entrepreneurship to realize the full potential of the opportunities that these funds will help unleash," says Jan Odegard, interim executive director of the Ion, in the release.

The Ion Smart and Resilient Cities Accelerator has cycled through two rounds of cohorts — first focusing on resilience and mobility in Cohort 1 then air quality, water purification, and other cleantech in Cohort 2.

The 12-week Clean Energy Accelerator was only recently announced by The Rice Alliance for Technology and Entrepreneurship at the annual Energy Tech Venture Forum earlier this month. The program is established to support Houston Mayor Sylvester Turner's Climate Action Plan.

Meanwhile, DivInc's accelerator comes out of a partnership with the Austin-based nonprofit and The Ion, which was announced in spring of this year. The goal with this program is to increase access to minority entrepreneurs.

"DivInc embodies the mindset that this generation and all the generations of innovators to follow must be inclusive of people of color and women entrepreneurs – who will build successful scalable growth companies to address tomorrow's challenges and opportunities," says Preston James, chief executive officer at DivInc, in the release.

"By removing the barriers that currently exist, we unleash this untapped potential and lift Houston to new economic heights. To do this we must establish strong collaboration with partners like The Ion, Rice University, the EDA and many others."

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

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.
