Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a podcast with the founder of a new venture firm, a former astronaut and recent award recipient, and a health care innovator with fresh funding.

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

Two astronauts recently received Presidential Medals of Freedom from President Joe Biden for their leadership in space.

Ellen Ochoa, the former center director and astronaut at the NASA's Johnson Space Center in Houston, and Jane Rigby, senior project scientist for NASA’s James Webb Space Telescope, were honored at the White House on May 3.

Ochoa spent 30 years with NASA, which included being the 11th director of JSC, deputy center director of JSC, and director of Flight Crew Operations. She served on the nine-day STS-56 mission aboard the space shuttle Discovery in 1993, and became the first Hispanic woman in space. She flew four more times to space with STS-66, STS-96, STS-110, and more.

“I’m so grateful for all my amazing NASA colleagues who shared my career journey with me,” Ochoa says in a NASA news release. Read more.

New VC firm aims to be the bridge between promising startups and Houston's innovation ecosystem

Houston innovators podcast Episode 236

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."


With his background that spans from the United States Military to academia and corporate venture, Ellis has had seats on nearly every side of the innovation table. But he says he was called to invest in founders of color after the murder of George Floyd. He says he also realized how much money was being left on the table by overlooking these innovators.

As one of the most diverse cities and the fourth largest city in the country, Houston is the place for Ellis's mission.

"The mission of South Loop is to become the preeminent source of venture capital dollars for underrepresented, diverse teams nationally to serve as a beacon for the best underrepresented talent and to enable them to be successful through leveraging the unique resources and talent of Houston," Ellis says. "A big part of our mission is also to help catalyze Houston as an ecosystem for tech entrepreneurship."

South Loop has six portfolio companies, including Houston-based Milkify, a breast milk freeze-drying service that went on to pitch and receive an investment on Shark Tank. Ellis says the firm expects to announce a handful of new investments over the next year or so. On the show, he explains more on what types of investment opportunities he's looking for and how founders can get in touch.

"The innovation is in the insight," he says. "We look to activate this community because we strongly believe in the power of founder insight."

Microsoft partners with Rice University's OpenStax on AI teaching tool

group project

Rice University’s OpenStax and Microsoft are partnering to integrate the nonprofit’s content with the tech giant’s AI innovation, known as Learning Zone.

“At OpenStax, our mission is to make an amazing education accessible to all,” Richard G. Baraniuk, founder and director of OpenStax, said in a news release. “That’s why we’re excited to integrate our trustworthy, peer-reviewed content with Microsoft’s AI technology through the Microsoft Learning Zone.

Houston ranks among the 15 best cities in America for 2025

Ranking It

A new national report ranking the best cities in America has declared Houston is the 13th best U.S. city in 2025.

The annual "America's Best Cities" report from Resonance Consultancy, a Canada-based real estate and tourism marketing firm, ranks the relative qualities of livability, cultural "lovability," and economic prosperity in America's principal cities with metropolitan populations of 500,000 or more.

These top 100 cities "brilliantly weave local culture with economic prospects, aligning with global and domestic travel trends to create premier experiences for both residents and travelers."

Houston's new placement is three spots lower than its triumphant No. 10 rank in 2024. Though it no longer holds a prized top-10 spot, the report hails Houston as a "coveted hometown for the best and brightest on earth."

Among Houston's other shining attributes are its booming population growth – which has now grown to a staggering 7.51 million people – plus its competitive real estate market and a vibrant hospitality and culinary scene. Additionally, Houston earned a well-deserved No. 4 rank in the report's "restaurants" subcategory.

"A 221-room Home2 Suites/Tru by Hilton debuted near Toyota Center in March, while Marriott’s newly renovated Residence Inn NASA/Clear Lake keeps surging visitors happy," the report said. "West Houston’s Greenside will convert 35,000 square feet of warehouses into a park-laced retail hub by 2026, while America’s inaugural Ismaili Center, rising along Allen Parkway, remains on schedule for later this year, adding yet another cultural jewel to H-Town’s festival-fueled mosaic."

The report additionally puts a large focus on Houston's innovative energy sector and its numerous large companies that boost the local economy and create thousands of jobs. Several of these Houston-based companies are some of the best places to work, according to U.S. News and World Report.

One such company that was specifically praised in the report was the HyVelocity Hub, which aims to "ensure economic resilience and long-lasting, domestic energy production" along the Gulf Coast.

"The HyVelocity Hydrogen Hub just locked in up to $1.2 billion from the U.S. DOE, targeting 45,000 jobs and slicing 7.7 million tons of CO₂ a year," the report said.

Elsewhere in Texas

Dallas (No. 14) and Austin (No. 15) ranked right behind Houston in the top 20, while San Antonio sank into the No. 41 spot after previously ranking 32nd last year. El Paso also fell from No. 83 in 2024 to No. 100 this year.

Jason McGrath, the executive vice president and head of U.S. Corporate Reputation at Ipsos, said in the report that American cities are proving their resiliency as they are faced with "climate issues, increasing infrastructural demands, and shifting geopolitical landscapes affecting international relations and travel."

"Despite these hurdles, cities are creatively reinventing themselves to shine as examples of cultural vibrancy and innovation, keeping their competitive edge both locally and globally," McGrath said. "Our report shows that the allure of American cities remains strong, thanks to their rich diversity and vast attractions — from natural wonders to buzzing cultural hubs."

The top 10 best cities in America in 2025 are:

  • No. 1 – New York City, New York
  • No. 2 – Los Angeles, California
  • No. 3 – Chicago, Illinois
  • No. 4 – San Francisco, California
  • No. 5 – Seattle, Washington
  • No. 6 – Miami, Florida
  • No. 7 – Boston, Massachusetts
  • No. 8 – Washington, D.C.
  • No. 9 – Las Vegas, Nevada
  • No. 10 – San Diego, California

Houston biosciences company opens new sequencing center for drug development

bioscience breakthroughs

Houston-based Avance Biosciences has launched the Next-Generation Sequencing Center of Excellence, designed to enhance the company’s sequencing capabilities for drug development. Specifically, the facility at the company’s main campus in Northwest Houston will pursue breakthroughs in biologics, cell therapy and gene therapy.

In the drug industry, sequencing refers to studying nucleotides in DNA and RNA molecules. Nucleotides are the building blocks of DNA and RNA.

“This is a major milestone for Avance Biosciences as we continue to support the evolving needs of biologics and cell and gene therapy developers,” Xuening “James” Huang, co-founder, CEO and chief technology officer of Avance, said in a news release. “By consolidating state-of-the-art sequencing platforms and scientific talent, we’ve created a highly capable organization ready to solve complex genomic challenges with precision and compliance.”

In 2013, Avance rolled out next-generation sequencing (NGS) that complies with federal guidelines. Since then, Avance “has remained at the forefront of regulated sequencing services,” the company said. “The launch of the (new center) strengthens the company’s ability to deliver accurate, reproducible, and regulatory-aligned sequencing data across a wide array of therapeutic modalities.”

Cal Froberg, senior vice president of sales and marketing at Avance, said pharmaceutical and biotech clients trust the company’s technical capabilities and regulatory compliance.

“With the ever-changing global landscape and increasing scrutiny around international sample shipments, conducting advanced, cost-effective NGS testing domestically is now more feasible than ever,” Froberg said. “Our clients have confidence that their samples will remain in the U.S.”

Avance, founded in 2010, plans to hold an open house at the new facility in September to showcase its capabilities, technology, talent, and services. The company’s services include sequencing, molecular biology, cell-based testing, and bioanalytical testing.
