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.”

Experts: What Houston startup founders need to know about conducting a successful IPO

guest column

Home to a wealth of world-changing innovations and a highly skilled labor pool, Houston has attracted startups and digital tech firms for years. Today, the city stands at the forefront of a promising era with seven Houston startups beginning the year strong with more than $380 million in venture funding, and the city ranked among the top emerging startup ecosystems in North America

Houston-based startups planning their exit strategies have good reason to be optimistic about an initial public offering, or IPO, market that is expected to grow in 2024. After a two-year slump in startup investing, some market watchers are predicting that the IPO window may reopen as the economy improves and inflation and interest rates cool.

But good timing requires good readiness. The window of opportunity for preparation now appears to be a microwindow. As any company that went public at the peak of the dot-com or post-COVID booms can attest, preparation is essential to quickly take action when the time is right. Hitting that microwindow will require that IPO-bound Houston companies be strategic about their IPO readiness planning. A lack of planning can result in an IPO experience that is not well planned, and potentially a missed opportunity altogether.

It’s unclear when the next IPO window will open, or for how long the window will remain open, but it could happen quicker than expected. This unpredictability suggests that Houston startups seeking to go public should start their legal, financial, and regulatory planning now. The important period for many companies planning an IPO begins six to 18 months prior to listing and lasts until the six months post-IPO.

Readying an IPO

We gained several insights from our discussions with CEOs and CFOs who have effectively navigated IPOs recently to provide insights for companies contemplating going public when the next microwindow opens. A company’s comprehensive readiness plan can be key to performing well in the market, whether it is up or down. Summarized below are common key areas that challenged many C-Suite executives in being a public company and, in hindsight, areas they wished they had addressed earlier in the process.

  1. Internal forecasting. Internal forecasting is paramount. In fact, it’s one of the primary takeaways cited in our conversations with the C-suite execs who went through the IPO process. Houston companies on an IPO track should be prepared to provide accurate forecasting and timely fulfillment of projections. Missing projections can result in significant regulatory repercussions.
  1. Key performance indicators and non-GAAP measures. Take reasonable steps towards performing a comprehensive benchmarking study to determine relevant KPIs and non-GAAP measures and metrics to report upon; be ready with the frameworks in place to report upon during quarterly and annual reporting.
  1. Growth story. The ability to communicate the company’s growth story can be essential to an effective IPO. Company leaders should be able to clearly convey topics such as the company’s growth, vision and strategy, its plans for improving performance metrics, the market opportunity, its competitive edge, and how its product or services will meet market demand. Meetings with analysts and other market influencers are also necessary to gain investor support. The executives we talked to said that when they did not invest time in this awareness-building step, they often found themselves rushing to get the word out as the offering date closed in.
  1. Finance infrastructure and human capital. Understand the infrastructure and operating model required to operate as a public company, along with the human capital necessary to sustain operations. Identifying the necessary skillsets and bandwidth within the team supports a smoother IPO process. Collaborating with experienced, independent advisors is also vital. These advisors assist in organizing the process, outlining SEC reporting requirements, updating SEC-compliant financial reporting, preparing Management Discussion and Analysis (MD&A) and pro forma financial information, and offering guidance throughout the pre-IPO preparation.
  1. Governance. IPO-bound companies need to anticipate new corporate governance requirements as a publicly traded entity, particularly in terms of their board of directors. Proper governance and board oversight can be essential to support the quality of financial statements produced by management. Executives told us that recruiting the right board members is often a significant pre-IPO challenge. Identifying these members early is crucial, as the right resources may not be available later.

Closing thoughts

If you are among those companies looking to go public in the near future, now is the time to get your house in order. Companies are often surprised to discover how much preparation it truly takes to operate as a public company. In fact, we typically recommend starting the preparation journey 18 to 24 months before the anticipated public listing date. Simply stated, if you wait until the IPO window opens before gearing up, you likely will be gearing up for the next window.

European spacecraft developer expands to Houston with U.S. business, new lab

houston hq

European aerospace manufacturer The Exploration Company has established its first U.S. entity and named Space City as its headquarters.

The company announced earlier this month that it has launched TEC Federal to support U.S. government customers and agencies, and to scale The Exploration Company's engineering operations in the country.

Mark Kirasich serves as president of TEC Federal. Kirasich most recently served as the senior director of human spaceflight at Blue Origin after a nearly 40-year career at NASA.

The Exploration Company is developing the reusable Nyx space vehicle. Nyx is designed to take off from any heavy launcher in the world. It will then dock at space stations, retrieve up to 3,000 kilograms of cargo, splash down and return the cargo to Earth. The company aims to make Nyx fully reusable for up to 10 missions, making it a more affordable and sustainable option for aerospace missions.

The Exploration Company completed a successful drop test of the spacecraft in May in the Mojave Desert. The company says Nyx is slated to perform its first flight demonstration in 2028.

In addition to launching the Houston business, The Exploration Company also opened its new Rapid Innovation Lab near Houston's NASA Johnson Space Center on Space Park Drive.

The Rapid Innovation Lab features a full-scale mockup of the future Nyx crew capsule as well as ongoing development and testing of the Nyx cargo capsule, according to the company.

The Exploration Company says the new lab will allow its engineers, designers, and operators to prototype and test crew interfaces. It will also support partnerships with NASA personnel and astronauts.

“Houston gives us direct access to the people and expertise that have built and operated human spaceflight systems for decades. We’re excited to invest and expand around that— engineers, operators, and astronauts working together and moving quickly towards building a crew capsule.” Hélène Huby, founder and CEO of The Exploration Company, said in a blog post.

According to The Houston Chronicle, The Exploration Company has about 30 employees in the Houston area.

The company was founded in 2021 by Huby, a French rocket scientist, and has raised more than $350 million in venture capital. It operates out of Germany, France, Luxembourg, Spain and Italy, with offices in the U.S. and the United Arab Emirates. It is also developing a reusable, high-thrust rocket engine known as Storm.

UH lands $4M NIH grant to study early signs of autoimmune disease

NIH funding

The University of Houston recently received a $4 million National Institutes of Health grant to support a 10-year longitudinal study to identify the earliest biological markers of autoimmune disease.

Led by Chandra Mohan, the Hugh Roy and Lillie Cranz Cullen Endowed Professor of Biomedical Engineering, the study aims to examine what causes Systemic Autoimmune Rheumatic Diseases (SARDs) and to identify targets for future treatments. The study will be carried out in collaboration with Dr. Karen Costenbader at Harvard Medical School, Boston.

SARDs include conditions like rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome and systemic sclerosis—all are considered chronic diseases currently without a cure. Autoimmune diseases affect over 30 million people globally, according to UH.

SARDs occur when the body’s immune system attacks healthy, non-threatening tissues and organs. According to UH, in these diseases, the body often attacks nuclear antigens, creating anti-nuclear autoantibodies, which can be early detection signs for SARDs in more than 50 percent of patients, Mohan says.

Researchers will study blood samples and environmental exposure over the 10 years to better understand anti-nuclear autoantibodies.

“Collectively, these studies will help identify the genetic, environmental and cellular factors that are operative at the two steps of SARD development, namely the emergence of anti-nuclear autoantibodies and disease onset,” Mohan said in a news release. “ More importantly, these studies will highlight functional molecular pathways and mechanisms that may be operative at each step."

Mohan predicts that looking at SARDs’ shared characteristics, rather than each disease individually, could help identify more treatment methods.

“Individual SARDs have been examined in silos without an attempt to discern shared underlying features at the molecular level,” he added in the release. “Current understanding of the initial (and likely shared) origins of SARDs is only rudimentary but urgently needed to develop means for prevention and treatment.”

Earlier this year, UH also received an $11 million NIH grant to conduct a first-of-its-kind study of early language development in children ages 18 to 24 months. Read more here.
