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.”

Zach Ellis Jr., founder and general partner of South Loop Ventures, says the firm wants to address the "billion-dollar blind spot" of inequitable distribution of venture capital to underrepresented founders of color. The Houston-based firm recently closed its debut fund for more than $21 million. Learn more.

Ty Audronis and his company, Tempest Droneworx, made a splash at SXSW Interactive 2025, winning the Best Speed Pitch award at the annual festival. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine. Audronis says his company won based on its merits and the impact it’s making and will make on the world, beginning with agriculture. Learn more.

Houston-based Persona AI and CEO Nicolaus Radford continue to make steps toward deploying a rugged humanoid robot, and with that comes the expansion of its operations at Houston's Ion. Radford and company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the building, with the expansion slated to begin in June. “We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” Radford says.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
