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 was recognized for her leadership at NASA Johnson and for being the first Hispanic woman in space. Rigby was honored for her work on leading NASA’s transformational space telescope.

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.

Rigby has published 160 peer-reviewed publications. She has been recognized with various awards like NASA’s Exceptional Scientific Achievement Medal, the Fred Kavli Prize Plenary Lecture from the American Astronomical Society (AAS), and the 2022 LGBTQ+ Scientist of the Year from Out to Innovate. Currently, she is an astrophysicist at NASA’s Goddard Space Flight Center.

Part of Rigby’s Medal of Freedom honor is due to her role in the success of NASA’s Webb mission. Webb is considered the most powerful space telescope, which launched on Dec. 25, 2021.

“I am proud Ellen and Jane are recognized for their incredible roles in NASA missions, for sharing the power of science with humanity, and inspiring the Artemis Generation to look to the stars,” says NASA Administrator Bill Nelson in the release. “Among her many accomplishments as a veteran astronaut and leader, Ellen served as the second female director of Johnson, flew in space four times, and logged nearly 1,000 hours in orbit. Jane is one of the many wizards at NASA who work every day to make the impossible possible. The James Webb Space Telescope represents the very best of scientific discovery that will continue to unfold the secrets of our universe. We appreciate Ellen and Jane for their service to NASA, and our country.”

These 50+ Houston scientists rank among world’s most cited

science stars

Fifty-one scientists and professors from Houston-area universities and institutions were named among the most cited in the world for their research in medicine, materials sciences and an array of other fields.

The Clarivate Highly Cited Researchers considers researchers who have authored multiple "Highly Cited Papers" that rank in the top 1percent by citations for their fields in the Web of Science Core Collection. The final list is then determined by other quantitative and qualitative measures by Clarivate's judges to recognize "researchers whose exceptional and community-wide contributions shape the future of science, technology and academia globally."

This year, 6,868 individual researchers from 60 different countries were named to the list. About 38 percent of the researchers are based in the U.S., with China following in second place at about 20 percent.

However, the Chinese Academy of Sciences brought in the most entries, with 258 researchers recognized. Harvard University with 170 researchers and Stanford University with 141 rounded out the top 3.

Looking more locally, the University of Texas at Austin landed among the top 50 institutions for the first time this year, tying for 46th place with the Mayo Clinic and University of Minnesota Twin Cities, each with 27 researchers recognized.

Houston once again had a strong showing on the list, with MD Anderson leading the pack. Below is a list of the Houston-area highly cited researchers and their fields.

New report shows surge in startup activity in Houston and across Texas

by the numbers

Houston and the rest of Texas are experiencing a boom in the creation of startups.

One barometer of growth in startup activity: The Houston metro area saw a 92 percent rise from 2024 to 2025 in the number of account applications submitted to Bluevine, a banking platform for small businesses.

New data from Bluevine also shows healthy year-over-year growth in account applications submitted by entrepreneurs in Texas’ three other major metros:

  • 242 percent growth in the San Antonio area
  • 153 percent growth in the Austin area
  • 28 percent growth in Dallas-Fort Worth

Further evidence of Texas’ uptick in business creation comes from a new state-by-state analysis of U.S. Census Bureau data by digital mailbox provider iPostal1.

From 2019 to 2024, the number of new business applications jumped 60 percent in Texas, according to the iPostal1 analysis. Wyoming tops the list, with a five-year growth rate of 216 percent.

“The U.S. has no shortage of ambition, but opportunity isn’t spread evenly,” says Jeff Milgram, founder and CEO of iPostal1. “In states like New York, Florida, and Texas, entrepreneurship is booming — people are starting businesses, taking risks, and finding opportunity.”

“Other states are still catching up,” Milgram adds. “Sometimes it’s access to funding, sometimes local policy, or just the confidence that new ventures will be supported.”

Women own many of the new businesses sprouting in Texas, according to a new analysis of 2024-25 data from the U.S. Small Business Administration. The analysis, done by SimpleTiger, a marketing agency for software-as-a-service (SaaS), shows Texas ranks eighth for the highest concentration of women entrepreneurs (109 per 1,000 female residents) among all states. That rate is three percent higher than the national average.

“Women entrepreneurs are no longer a side story in small business growth; they’re a leading indicator of where local economies are expanding next,” SimplyTiger says. “When women-owned business density is high, it usually signals stronger access to customers, networks, and startup pathways that make it easier to launch and keep going.”

In a December news release, Gov. Greg Abbott highlights Texas’ nation-leading job gains over the past 12 months, driven by employers small and large.

“From innovative startups to Fortune 500 corporations, job-creating businesses invest with confidence in Texas,” Abbott says. “With our strong and growing workforce, we will continue to expand career and technical training programs for better jobs and bigger paycheck opportunities for more Texans.”

Houston poised to add 30,900 new jobs in 2026, forecast says

jobs forecast

Buoyed by the growing health care sector, the Houston metro area will add 30,900 jobs in 2026, according to a new forecast from the Greater Houston Partnership.

The report predicts the Houston area’s health care sector will tack on 14,000 jobs next year, which would make it the No. 1 industry for local job growth. The 14,000 health care jobs would represent 45 percent of the projected 30,900 new jobs. In the job-creation column, the health care industry is followed by:

  • Construction: addition of 6,100 jobs in 2026
  • Public education: Addition of 5,800 jobs
  • Public administration: Addition of 5,000 jobs

At the opposite end of the regional workforce, the administrative support services sector is expected to lose 7,500 jobs in 2026, preceded by:

  • Manufacturing: Loss of 3,400 jobs
  • Oil-and-gas extraction: Loss of 3,200 jobs
  • Retail: Loss of 1,800 jobs

“While current employment growth has moderated, the outlook remains robust and Houston’s broader economic foundation remains strong,” GHP president and CEO Steve Kean said in the report.

“Global companies are choosing to invest in Houston — Eli Lilly, Foxconn, Inventec, and others — because they believe in our workforce and our long-term trajectory,” Kean added. “These commitments reinforce that Houston is a place where companies can scale and where our economy continues to demonstrate its resilience as a major engine for growth and opportunity. These commitments and current prospects we are working on give us confidence in the future growth of our economy.”

The Greater Houston Partnership says that while the 30,900-job forecast falls short of the region’s recent average of roughly 50,000 new jobs per year, it’s “broadly in line with the muted national outlook” for employment gains anticipated in 2026.

“Even so, Houston’s young, skilled workforce and strong pipeline of major new projects should help offset energy sector pressures and keep regional growth on pace with the nation,” the report adds.

The report says that even though the health care sector faces rising insurance costs, which might cause some people to delay or skip medical appointments, and federal changes in Medicare and Medicaid, strong demographic trends in the region will ensure health care remains “a key pillar of Houston’s economy.”

As for the local oil-and-gas extraction industry, the report says fluctuations and uncertainty in the global oil-and-gas market will weigh on the Houston sector in 2026. Furthermore, oil-and-gas layoffs partly “reflect a longer-term trend as companies in the sector move toward greater efficiency using fewer workers to produce similar volumes,” according to the report.
