More than 40 climatetech startups joined the Greentown Labs Houston community in the second half of 2025, 12 of which hail from the Bayou City.

The companies are among a group of nearly 70 total that joined the climatetech incubator, which is co-located in Houston and Boston, in Q3 and Q4.

The new companies that have joined the Houston incubator specialize in a variety of clean energy applications, from green hydrogen-producing water-splitting cycles to drones that service wind turbines.

The local startups that joined Greentown Houston include:

  • Houston-based Wise Energie, which delivers turnkey microgrids that blend vertical-axis wind, solar PV, and battery storage into a single, silent system.
  • The Woodlands-based Resollant, which is developing compact, zero-emissions hydrogen and carbon reactors to provide low-cost, scalable clean hydrogen and high-purity carbon for the energy and manufacturing sectors.
  • Houston-based ClarityCastle, which designs and manufactures modular, soundproof work pods that replace traditional drywall construction with reusable, low-waste alternatives made from recycled materials.

  • Houston-based Torres Orbital Mining (TOM),which develops autonomous excavation systems for extreme environments on Earth and the moon, enabling safe, data-driven resource recovery and laying the groundwork for sustainable off-world industry.

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Houston hailed as one of America's 10 best cities for startups

Startup Report

Houston's favorable economic climate is enticing new opportunities for entrepreneurship and growth, and now the city is being hailed as the 7th-best U.S. city for starting a business.

The recognition comes in CommercialCafe's recent "Best Cities for Startups" report, published December 10. The study analyzed large U.S. cities across two population categories – cities with more than 1 million residents and cities with populations between 500,000 and 1 million residents. The report analyzed relevant metrics such as office or coworking costs, Kickstarter funding success, startup density, and survival rates, among others.

Across the biggest U.S. cities with over a million residents, Phoenix, Arizona landed on top as the No. 1 best place to start a new business.

The report's findings revealed 10.6 percent of all businesses in Houston are startups that have been active for less than a year. These new businesses have a survival rate of 64.5 percent, meaning just under two-thirds of all startups in the city will still be running up to five years after they were first established.

Over the last five years, the number of new businesses established in Houston has grown nearly 15 percent. CommercialCafe said new businesses in cities with high startup growth rates tend to "attract top talent" which can eventually lead to securing "vital funding for expansion."

Independent professionals – also known as freelancers – are another crucial resource for new businesses that may need "specialized services" for a fixed amount of time, the report said. Houston's freelance workforce has grown about 9 percent from 2019-2023, and the analysis found there were 97,295 freelancers working in Houston in 2023, compared to 89,528 in 2019.

"Generally, cities in the South and Southwest have experienced strong growth during the surveyed period, in contrast to California cities like Los Angeles and San Diego, where the share of freelancers and gig workers has either stagnated or slightly declined," the report said.

Houston boasts the second-cheapest office space rent nationally, the report found. The average asking price for a 1,000-square-foot workspace (for five employees) in the city added up to $27,124 annually. For startups that want greater flexibility for their workers, the annual cost for a coworking space for the same number of employees in Houston came out to $13,200, which is the fourth-most affordable rate in the U.S.

Other Texas cities with attractive economic environments for startups

Texas, as a whole, is one of the strongest states for starting a new business. Other than Houston, San Antonio (No. 2), Dallas (No. 3), and Fort Worth (No. 4) were also recognized among the top 10 best places to start a business in the category of U.S. cities with more than a million residents.

Austin topped a separate ranking of best cities to start a business with 500,000 to 1 million residents.

"Specifically, the Texas capital was the frontrunner for indicators that looked at the overall share of startups within the local economy, as well as growth rates in five years (2019 to 2023)," the report said. "On top of that, Austin also topped the rankings for its percentage of college-educated residents and its consulting firms, which provide vital support for burgeoning enterprises."

The top 10 best cities to start a new business are:

  • No. 1 – Phoenix, Arizona
  • No. 2 – San Antonio, Texas
  • No. 3 – Dallas, Texas
  • No. 4 – Fort Worth, Texas
  • No. 5 – Jacksonville, Florida
  • No. 6 – San Diego, California
  • No. 7 – Houston, Texas
  • No. 8 – Philadelphia, Pennsylvania
  • No. 9 – Chicago, Illinois
  • No. 10 – Los Angeles, California

Texas tops ranking of best states for investors in new report

by the numbers

Texas ranks third on a new list of the best states for investors and startups.

Investment platform BrokerChooser weighed five factors to come up with its ranking:

  • 2024 Google search volume for terms related to investing
  • Number of investors
  • Number of businesses receiving investments in 2024
  • Total amount of capital invested in businesses in 2024
  • Percentage change in amount of investment from 2019 to 2024

Based on those figures, provided mostly by Crunchbase, Texas sits at No. 3 on the list, behind No. 1 California and No. 2 New York.

Especially noteworthy for Texas is its investment total for 2024: more than $164.5 billion. From 2019 to 2024, the state saw a 440 percent jump in business investments, according to BrokerChooser. The same percentages are 204 percent for California and 396 percent for New York.

“There is definitely development and diversification in the American investment landscape, with impressive growth in areas that used to fly under the radar,” says Adam Nasli, head analyst at BrokerChooser.

According to Crunchbase, funding for Texas startups is off to a strong start in 2025. In the first three months of this year, venture capital investors poured nearly $2.9 billion into Lone Star State companies, Crunchbase data shows. Crunchbase attributes that healthy dollar amount to “enthusiasm around cybersecurity, defense tech, robotics, and de-extincting mammoths.”

During the first quarter of this year, roughly two-thirds of VC funding in Texas went to just five companies, says Crunchbase. Those companies are Austin-based Apptronik, Austin-based Colossal Biosciences, Dallas-based Island, Austin-based NinjaOne, and Austin-based Saronic.

Texas-based 'DoorDash for laundry' startup tumbles into Houston market

No Scrubs

Laundry may seem like an endless task that piles up, but a new service offers a solution to overwhelmed Houston families.

NoScrubs, an Austin-based home laundry pickup service has just expanded to Houston. Described by the company as "DoorDash — but for laundry," they wash customer's clothes at local laundromats and return them the same day, folded and ready to be put away.

The service took off like gangbusters in Austin, making an expansion to the state's largest city an obvious choice. It's not universal coverage just yet.

For now, only the following ZIP codes have NoScrubs service available: 77002, 77004, 77005, 77006, 77007, 77008, 77009, 77010, 77018, 77019, 77024, 77025, 77027, 77046, 77056, 77057, 77081, 77098, 77401, 77030, 77003.

A single pickup starts at $40 for 20 pounds of laundry, while the basic monthly subscription is $60 for two pickups. All services use hypoallergenic detergents.

The average American family spends about 240 hours a year on laundry, making it a very time-consuming chore. For people with disabilities, difficult work schedules, and other circumstances, it can be a real help, says co-founder Matt O'Connor.

"Some of our favorite customer stories simply revolve around saving people time when they have something challenging going on," he writes in an email. "For example, one customer reviewed NoScrubs saying 'So happy I could cry! (Partially because I'm pregnant and my emotions are heightened!)...1000% recommend if you have time restrictions or physical restrictions! ' So, whether it’s saving time, the affordability, or the pleasantly surprising turnaround time, NoScrubs has a variety of benefits for any customer."

NoScrubs is also a new opportunity for Houston's gig workers. Because there are no passengers, it can be a safer alternative to driving ride share for women and other people apprehensive about having strangers in their cars. As NoScrubs partners with local laundromats, drivers are also going to centralized locations rather than all over the map, leading to less wear and tear on their cars. The laundromats benefit as well, since NoScrubs loads are ones that would otherwise be done at home.

"Our model makes driving a tiny fraction of the time, so folks who don’t want to wear down their vehicles and spend a ton on gas love working at NoScrubs," added O'Connor.

Innovative Houston-area hardtech startup closes $5M seed round

fresh funding

Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Fluxworks specializes in making contactless magnetic gears for use in extreme conditions, which can enhance in-space manufacturing. Its contactless design leads to less wear, debris and maintenance. Its technology is particularly suited for space applications because it does not require lubricants, which can be difficult to control at harsh temperatures and in microgravity.

The company received a grant from the Texas Space Commission last year and was one of two startups to receive the Technology in Space Prize, funded by Boeing and the Center for the Advancement of Science in Space (CASIS), in 2024. It also landed $1.2 million through the National Science Foundation's SBIR Phase II grant this fall.

Fluxworks was founded in College Station by CEO Bryton Praslicka in 2021. Praslicka moved the company to Conroe 2024.

5 Houston scientists named winners of prestigious Hill Prizes 2026

prized research

Five Houston scientists were recognized for their "high-risk, high-reward ideas and innovations" by Lyda Hill Philanthropies and the Texas Academy of Medicine, Engineering, Science and Technology (TAMEST).

The 2026 Hill Prizes provide seed funding to top Texas researchers. This year's prizes were given out in seven categories, including biological sciences, engineering, medicine, physical sciences, public health and technology, and the new artificial intelligence award.

Each recipient’s institution or organization will receive $500,000 in direct funding from Dallas-based Lyda Hill Philanthropies. The organization has also committed to giving at least $1 million in discretionary research funding on an ad hoc basis for highly-ranked applicants who were not selected as recipients.

“It is with great pride that I congratulate this year’s Hill Prizes recipients. Their pioneering spirit and unwavering dedication to innovation are addressing some of the most pressing challenges of our time – from climate resilience and energy sustainability to medical breakthroughs and the future of artificial intelligence,” Lyda Hill, founder of Lyda Hill Philanthropies, said in a news release.

The 2026 Houston-area recipients include:

Rosenberg and her team are developing ways to fight antibiotic resistance. The team will use the funding to screen a 14,000-compound drug library to identify additional candidates, study their mechanisms and test their ability to boost antibiotic effectiveness in animal models. The goal is to move toward clinical trials, beginning with veterans suffering from recurrent infections.

Medicine: Dr. Raghu Kalluri, The University of Texas MD Anderson Cancer Center

Kalluri is developing eye drops to treat age-related macular degeneration (AMD), the leading cause of vision loss globally. Kalluri will use the funding to accelerate studies and support testing for additional ocular conditions. He was also named to the National Academy of Inventors’ newest class of fellows last month.

Engineering: Naomi J. Halas, Rice University

Co-recipeints: Peter J. A. Nordlander and Hossein Robatjazi, Rice University

Halas and her team are working to advance light-driven technologies for sustainable ammonia synthesis. The team says it will use the funding to improve light-driven catalysts for converting nitrogen into ammonia, refine prototype reactors for practical deployment and partner with industry collaborators to advance larger-scale applications. Halas and Nordlander are co-founders of Syzygy Plasmonics, and Robatjazi serves as vice president of research for the company.

The other Texas-based recipients include:

  • Artificial Intelligence: Kristen Grauman, The University of Texas at Austin
  • Physical Sciences: Karen L. Wooley, Texas A&M University; Co-Recipient: Matthew Stone, Teysha Technologies
  • Public Health: Dr. Elizabeth C. Matsui, The University of Texas at Austin and Baylor College of Medicine
  • Technology: Kurt W. Swogger, Molecular Rebar Design LLC; Co-recipients: Clive Bosnyak, Molecular Rebar Design, and August Krupp, MR Rubber Business and Molecular Rebar Design LLC

Recipients will be recognized Feb. 2 during the TAMEST 2026 Annual Conference in San Antonio. They were determined by a committee of TAMEST members and endorsed by a committee of Texas Nobel and Breakthrough Prize Laureates and approved by the TAMEST Board of Directors.

“On behalf of TAMEST, we are honored to celebrate the 2026 Hill Prizes recipients. These outstanding innovators exemplify the excellence and ambition of Texas science and research,” Ganesh Thakur, TAMEST president and a distinguished professor at the University of Houston, added in the release. “Thanks to the visionary support of Lyda Hill Philanthropies, the Hill Prizes not only recognize transformative work but provide the resources to move bold ideas from the lab to life-changing solutions. We are proud to support their journeys and spotlight Texas as a global hub for scientific leadership.”

Investment bank opens new Houston office focused on energy sector

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.
