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.”

Houston ranked in the top emerging North American startup ecosystems

We're No. 4!

The evolution of Houston’s startup scene continues: A new report awards the region a No. 1 ranking for the robustness of early-stage funding among North America’s emerging startup ecosystems.

Policy advisory and research firm Startup Genome reports that startups in the Houston area attracted $884 billion in early-stage funding from the second half of 2020 to the end of 2022. Early-stage funding generally refers to a startup’s seed and series A rounds.

The $884 million figure puts Houston at No. 1 for early-stage funding among emerging startup ecosystems in North America and at No. 9 globally. Istanbul, Turkey, grabs the top global spot. Startup Genome characterizes the funding meccas in this ranking category as “Strong Starters.”

Startup Genome’s 2023 report on startup ecosystems emphasizes that early-stage funding “is an important indicator of potential success,” since most startups that receive series A rounds have demonstrated their potential by generating revenue, creating a minimal viable product, or being close to launching a product.

In Startup Genome’s global ranking of emerging startup ecosystems as a whole, Houston falls to No. 11 this year from No. 5 in 2022. The report doesn’t cite a reason for the drop. Copenhagen, Denmark, takes the No. 1 ranking in this category.

While its global ranking slipped, Houston still makes this year’s list of the top five emerging ecosystems in North America:

  1. Detroit (same position as last year)
  2. North Carolina’s Research Triangle (up two spots from last year)
  3. Minneapolis (down one spot from last year)
  4. Houston (down one spot from last year)
  5. Phoenix (up two spots from last year)

Startup Genome pegs the value of Houston’s startup ecosystem at $22 billion, based on startup exits and valuations from the second half of 2020 to the end of 2022.

A 2022 report from the Greater Houston Partnership noted that the Houston area is home to more than 60 organizations that foster startup growth. These include incubators, accelerators, coworking spaces, makerspaces, college and university programs, and nonprofit initiatives.

“These organizations have formed a growing web of resources assisting tech entrepreneurs across the Houston region,” says the report.

Silicon Valley once again tops Startup Genome’s list of the world’s leading startup ecosystems, followed by New York City and London (tied at No. 2), Los Angeles (No. 4), and Tel Aviv, Israel (No. 5).

Startup Genome defines a startup ecosystem as a shared pool of resources generally within a 60-mile radius of a central point, such as the city of Houston. These resources include accelerators, incubators, funding groups, coworking spaces, schools, and policymakers.

Startup Genome’s six ranking factors for ecosystems are performance, funding, talent and experience, market reach, knowledge, and “connectedness.”

“Despite current economic challenges, we are confident that, equipped with the right knowledge, entrepreneurs, policymakers, and community leaders everywhere can leverage opportunities to come together and show how innovative technologies can not only continue to drive growth and job creation, but simultaneously help save the planet and ensure a better future for everyone,” JF Gauthier, founder and CEO of Startup Genome, says in a news release. “This essential mission cannot be put on hold while we wait out rocky economic times.”

Houston tech ecosystem ranks as No. 5 in the world for emerging startup hubs

tech in texas

As a startup hub, Houston is movin’ on up.

In a new report from Startup Genome and the Global Entrepreneurship Network, Houston ranks fifth among the world’s top 100 emerging ecosystems for startups. Last year, the groups’ report put Houston at No. 19 in the same category.

Ahead of Houston on the list of the top emerging ecosystems for startups are first-ranked Detroit; second-ranked Hong Kong; third-ranked Dublin, Ireland; and fourth-ranked Minneapolis.

Further bolstering Houston’s status as a rising startup hub, Bayou City ranks third among the top North American challengers to traditional startup anchors like Silicon Valley, Boston, and Seattle. Joining Houston on the challengers’ list are first-ranked Detroit; second-ranked Minneapolis; third-ranked Research Triangle, North Carolina; and fifth-ranked Pittsburgh.

A recent report from Houston Exponential, which was recently acquired, emphasizes Houston’s position as the third fastest-growing tech ecosystem in the U.S. for early-stage startups. Houston sits behind Miami (No. 2) and Bridgeport-Stamford-Norwalk, Connecticut (No. 1).

Houston startups at all stages raised $2.34 billion in 2021, setting a record for the region’s annual VC haul, the HX report says. Of that total, early-stage startups collected $618.9 million in 46 deals.

Health and information technology startups dominate the VC landscape in Houston, with each accounting for 30 percent of VC deals in 2021, according to the HX report.

Elsewhere in Texas, Austin ranks 25th among the world’s top 100 ecosystems for startups, while Dallas ties for 31st place, according to the Startup Genome and Global Entrepreneurship Network report. San Antonio is wedged into the 91-to-100 range in the ranking of the world’s top 100 ecosystems.

“The importance and dispersal of tech startups have amplified the influence — for both good and ill — of geopolitics,” the report notes. “Where once the sector was sufficiently small to avoid the kind of pressures experienced by large industries such as energy and travel, those garage-spawned entrepreneurs have grown into a major economic force. Keeping their heads down is no longer an option.”

Houston rise in the ranks of the top emerging ecosystems in the world

stacking up

If you need evidence that Houston's startup ecosystem is flourishing, look no further than a new report from Startup Genome and the Global Entrepreneurship Network.

This year's Global Startup Ecosystem Report, released September 22, places Houston at No. 19 among the world's top 100 emerging startup ecosystems. Furthermore, it puts Houston at No. 4 among the top regional challengers in North America. Last year's report lumped Houston with other emerging startup ecosystems in the 31-to-40 ranking range.

Mumbai, India, appears at No. 1 among the world's top 100 emerging startup ecosystems this year, while Miami lands at No. 1 among the top regional challengers in North America.

According to Houston Exponential, the city's startup ecosystem "is experiencing a growth spurt that appears to show no signs of abating."

Case in point: Houston startups raised more than $1 billion in the first six months of 2021, surpassing all annual totals from previous years. In 2020, Houston startups reaped a record-high $753 million in venture capital.

"Venture capital invested in Houston startups has nearly quadrupled since 2016," according to a recent Houston Exponential report. "The sustained level of progress we've seen in startup formation and growth over the past four years shows that Houston has what it takes to build a vibrant, healthy innovation economy with an emphasis on equity."

Collectively, the health care and information technology sectors accounted for nearly 60 percent of Houston's VC deals in the first half of 2021, the report says.

Another sign of the expansion of Houston's startup ecosystem: the rising number of workspaces, incubators, and accelerators designed to foster startups.

"These key institutions create density and drive collisions among founders, investors, and talent, significantly increasing the rate of startup formation and growth," according to the Greater Houston Partnership.

Those institutions include The Ion entrepreneurial hub, the Greentown Labs climate-tech incubator, and the DivInc startup accelerator. All are new arrivals on the Houston startup scene.

"DivInc is about broadening the startup ecosystem by making it more authentically diverse, equitable, and inclusive of underrepresented entrepreneurs," Preston James II, CEO of DivInc, said in April. "When we, as a community, do this successfully, we optimize our opportunities for economic GDP growth, we can help reduce racial/gender wealth divide, and drive greater innovation."

Elsewhere in Texas, Austin ranks 20th among the leading startup ecosystems in the Global Startup Ecosystem Report, down from No. 19 last year, and Dallas repeats its 31st-place tie. Silicon Valley tops the global list.

The report says North America represents half of the top 30 ecosystems in the world.

"Entrepreneurs, policymakers, and community leaders in North America have been working hard to build inclusive innovation ecosystems that are engines of economic growth and job creation for all," JF Gauthier, founder and CEO of Startup Genome, says in a news release.

San Francisco-based Startup Genome is a research and advisory firm specializing in startup ecosystems.

Shell commits to $10M carbon initiative with Rice University, Houston startup acquired by Honeywell, and more innovation news

Short Stories

Even toward the end of the year and amid the holiday season, Houston's innovation news can be a lot to keep up with. Here are seven short stories of Houston innovation — from an exit for a Houston startup and a multimillion-dollar clean energy commitment from Shell to new national recognitions for Houston and 2020 plans unveiled for MassChallenge in Houston.

Shell commits $10 million to new Carbon Hub at Rice University

Rice University has introduced its Shell-backed Carbon Hub — a research initiative to innovate zero-emissions technologies. According to a news release, Shell has committed to a $10 million arrangement for the hub.

"Trying to address climate change is like playing whack-a-mole; you think you're making something better, and you realize that made something else get worse," says Carbon Hub director, Matteo Pasquali, in the release. "For example, you make cars more fuel efficient by removing weight, and then realize you've increased CO2 emissions by using more aluminum and carbon fibers. Or you try to fix CO2 into a useful product, and you realize you now need much more energy than you had gotten by making the CO2 in the first place."

The plan is to "fundamentally change how the world uses hydrocarbons," reads the release. Rather than burning hydrocarbons for fuel, creating carbon dioxide, the hydrocarbons "will be split to make clean-burning hydrogen fuel and solid carbon materials that can be used to make buildings, cars, clothing and more."

Through the partnership with Shell — and other potential partners — the hub will help fund and lead $100 million of science and engineering initiatives. The inaugural meeting for the hub is expected to be early next year and will be hosted by The Center for Energy Studies at Rice's Baker Institute for Public Policy.

"Providing energy to the world's population in an economically and environmentally sustainable manner is the global energy challenge," says Ken Medlock, senior director of the Center for Energy Studies, in the release. "In part, this will require new technologies and forward-looking, creative thinking, which is exactly what Carbon Hub offers."

Innovative gas monitoring technology company, Rebellion Photonics, founded by Allison Sawyer and Robert Kester in Houston in 2009, has been acquired by Honeywell for an undisclosed amount.

The business will be rolled into Honeywell's Safety and Productivity Solutions business, as well as through Honeywell's Performance Materials and Technologies business, according to a press release.

"Honeywell is an amazing company and a recognized leader in our industry. We are excited to be part of their world-class family," Kester, who serves as CEO of Rebellion Photonics, says in the release. "Automated visual monitoring is the future of gas leak detection. Combining our products with Honeywell's platform will make this the new industry standard for safety and environmental monitoring globally."

Houston just made it onto the list of the top 50 cities to start a business, according to Surge Cities index, Inc., and Startup Genome. Coming in at No. 45, the Bayou City ranked behind Austin (No. 1) and Dallas (No. 29).

"Houston wants to be known as the Third Coast, a place that is both a business and cultural hub," the blurb on Inc. reads. "A place where people want to be. And this city, one of the most diverse in the country, is well on its way."

The report highlights Houston's historic hold on the oil and gas industry, the Texas Medical Center's established presence, and the space innovation happening at NASA. Roger Griesmeyer, a partner at Hunton Andrews Kurth, says in the article that Houston has low regulations and taxes coupled with "a highly educated populace, great weather, and a bunch of money."

"There's such diversity and a confluence of talent and opportunity in one place," says Griesmeyer in the article. "Houston is selling a lifestyle brand with all the resources to bear."

Houston was ranked highly on three factors:

  • No. 23 for job creation
  • No. 20 for wage growth
  • No. 25 for population growth

Houston hardtech accelerator names 8 founders to 2026 cohort

hardtech fellows

Hardtech-focused organization Activate has named 50 new members to its 2026 cohort of scientists, which includes eight startups joining Activate Houston.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. Its fellows receive a living stipend, research and development funding, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

This year's fellows represent 41 companies from 22 U.S. cities and 11 states.

“This cohort clearly demonstrates that the next industry-defining companies won't choose between modern technology and deep science; they'll be built by combining both,” Cyrus Wadia, CEO of Activate, said in the announcement. “These are the scientists and engineers turning our most urgent global challenges into the companies that will deliver a more sustainable future.”

The Houston fellows are working across the energy, space, AI infrastructure and agriculture sectors. They include:

  • Sophie Clare Broun, founder of Anning Corporation, which is producing clean hydrogen by stimulating naturally occurring geologic deposits
  • Kathy Andersen, founder of Brint Tech, which builds optical sensing systems that quantify hydrogen for infrastructure operators
  • Dorsa Talebi, founder of Kinetiq Drive, which builds rare-earth-free, contact-free electric motors with wireless rotors for small appliances and heavy industry alike
  • Neethu Pottackal, founder of Nivera, which is developing natural, edible coatings made from agricultural byproducts to reduce food waste and extend the shelf life of fresh food
  • Jonathan Huffman, founder of Orbital Arc, which is shrinking spacecraft propulsion to a microchip powerful enough for deep space
  • Tim Lee, founder of Renesin, which develops advanced materials for faster, more efficient AI hardware
  • Joshua Livingston, founder of Selerra Separations, which is developing high-performance membranes that cut the cost and energy consumption of water treatment
  • Wenli Jiang, founder of SwieNitro Recovery, which is developing technology that converts nitrogen-rich waste streams into valuable fertilizer

"Home to the largest concentration of engineers in the United States and a dense ecosystem of Fortune 100 and Fortune 500 companies, Houston is uniquely positioned for scientists tackling large-scale industrial challenges. Activate Houston fellows are connected to the city's deep networks in energy, chemicals, and materials," Activate said in the announcement.

Activate named its inaugural Houston cohort in 2024. It has other hubs in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Nationally, it has supported 346 fellows and 276 companies since 2015.

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.

Tesla self-driving mode wasn't to blame in Houston-area crash, report suggests

Tesla news

Federal safety investigators looking into a runaway Tesla that killed a grandmother in her home say the driver had pressed the accelerator to full speed, suggesting the vehicle's self-driving software was not to blame.

The driver had told police that he had the self-driving software turned on, but a report from the National Transportation Safety Board concluded that he had actually overridden that feature when he pushed hard on the pedal. Moments later the Tesla Model 3 raced down a residential street in Katy, Texas, at highway speeds, slammed into a brick home and killed a 76-year-old woman standing in the front room.

The crash last month drew national attention because Tesla CEO Elon Musk is seeking to reassure the public its self-driving feature is safe as he prepares to turn hundreds of thousands of Teslas already on the road into fully automatic vehicles and begin selling two-seated Cybercabs missing steering wheels and pedals.

The crash came two months after officials at a separate federal agency, the National Highway Traffic Safety Administration, announced it was elevating a 2024 investigation of the self-driving feature to new “engineering analysis” level, raising the possibility of a recall of 3.2 million Tesla vehicles.

That NHTSA probe was triggered by crashes where the self-driving feature failed to alert drivers to take control in fog and other poor visibility conditions.

The agency opened an investigation last year into 58 incidents in which Teslas reportedly violated traffic safety laws while using self-driving technology, leading to more than a dozen crashes and fires and nearly two dozen injuries.

Separate from the National Transportation Safety Board, NHTSA is also looking into the Tesla house crash in Texas, one of 46 “special crash” investigations of Tesla's self-driving or driver-assistance technology in the past decade, according to the agency’s records. In more than a dozen of those crashes, at least one person — a driver, passenger or pedestrian — was killed.

Tesla had originally called its driver assistance software Full Self-Driving, or FSD, but auto experts and regulators complained it was misleading because drivers must always keep their eyes on the road and be ready to take over at any time.

The company has since changed the name to Full Self-Driving (Supervised).

Video of the Katy, Texas, accident shows the Tesla traveling at more than 70 mph (112.65 kilometers per hour), jumping a curb then tearing across a lawn before crushing through a brick wall of a home. A woman standing feet away, Martha Avila, was found amid piles of crumbling plaster, split beams and bits of furniture and rushed to a hospital but died.

Sales of Tesla cars still haven't recovered fully from boycotts last year over Musk's political stands, but the stock is rising anyway as he has successfully shifted attention away from the sales figures. He says they matter less now that the company is on the cusp of major technological advances, such as turning Teslas into hands-free vehicles and having its Optimus robots take over for humans for tasks at home and work.

Tesla stock has risen 22% in the past year and is currently trading at 170 times expected annual earnings compared to 20 for the S&P 500.

For its second-quarter financial results, financial analysts surveyed by FactSet expect earnings per share will barely budge — 32 cents versus 33 cents a year earlier — continuing a sixth quarter streak of flat or falling profits.
