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.

Deloitte’s complimentary IPO SelfAssess tool can help you gauge your ability to go public with a tailored assessment. The tool provides you with useful insights and identifies potential areas for improvement based on the feedback you provide.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota
