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.

Houston startup secures $10M to expand into rural communities

ready to grow

A Houston company that is working on a value-based model for primary care has fresh funding to support its mission.

Hamilton Health Box announced the completion of a $10 million series A funding round led by 1588 Ventures with participation from Memorial Hermann Health System, Impact Ventures by Johnson & Johnson Foundation, Texas Medical Center Venture Fund, and the Sullivan Brothers.

The company, founded in 2019 by Dr. Toby R. Hamilton, will use the funding to fuel its expansion into rural areas to help assist those living in Health Professional Shortage Areas, or HPSAs.

The company has pioneered a proprietary “small footprint primary care delivery model,” which is considered suitable for rural markets, employer worksites, office buildings, schools, and university campuses. The cost-effective microclinics are “prefabricated facilities” that are designed for primary care services, and employ a hybrid in-person and telemedicine care approach.

Hamilton began his career as a physician before founding Emerus Holdings, which is a micro-hospital system in the Houston area that later moved to private equity.

The recently acquired funding will help expedite the high-touch care model to 98 million Americans in HPSAs, which was a goal for when the company was established during the Covid-19 pandemic. HHB has made partnerships with Federally Qualified Health Centers (FQHCs) to provide primary care services both at existing FQHC centers and through new sites in rural areas.

"Hamilton Health Box that was designed to deliver the lowest possible price of primary and preventative care," Hamilton said in a previous interview with Innovation Map. "We built that to be able to take that care to the jobsite and meet the customer where they are at."

Dr. Toby Hamilton has seen Houston establish itself as a leader in health innovation, and he's been a part of that journey too. He started his career as a physician before founding Emerus Holdings, a micro-hospital system in the Houston area which later exited to private equity. He also founded a nonprofit focused on connecting hospital innovation leaders called the Healthcare Innovators Professional Society and led the Texas Medical Center's Biodesign program for two years.

Over the years, he says he's seen the potential develop for Houston to hold a significant role in health care innovation across the world — it's just going to take all hands on deck.

"As a community, if we can get behind that vision and be the place that tests, develops, and creates opportunities, Houston has the potential to be unlike anything in the world," he says on the Houston Innovators Podcast. Click here to listen and read more.

One of Houston's coworking companies is moving on up. Sesh Coworking is moving into a new space that's 10 times as large as its original location — and it's an optimal location too, say Meredith Wheeler and Maggie Segrich, founders of Sesh Coworking.

"Being able to grow our community at our beautiful original location in Montrose through the pandemic is a testament to the grit and resilience of Houstonians. We are so honored and grateful to be a part of their journey,” says Segrich. “We are excited that our new location in Midtown, near the Innovation District, will provide more Houstonians with the workspace and support they need."

The two-story space is expected to open in two phases. Tenants will first move into the space's second floor in January while the first floor, the larger of the two floors, completes construction and is expected in March. Click here to read more.

The greatest gymnast of all time has a new title to her many gymnastics accomplishments. Simone Biles recently joined mental health startup Cerebral as chief impact officer, and the company is backed by SoftBank and has a valuation of $4.8 billion.

Biles has been vocal about her passion for mental health. Cerebral was an official sponsor of Biles’ Gold Over America Tour, which took place from September to November, and is an official sponsor of the 2022 Simone Biles International Invitational, a gymnastics competition that will be held January 27-30 at Houston’s George R. Brown Convention Center. The Spring-based World Champions Centre, Biles’ home gym, stages the invitational.

“Mental health is just as important as physical health, but for far too long the stigma of mental health has prevented too many people from seeking help,” Biles says in a Cerebral news release. “I have my own challenges with mental health, and therapy has been very empowering for me as I try to be the best person that I can be. I believe everyone should have access to mental health resources, and Cerebral gives me the ability to personalize my mental health care experience.” Click here to read more.

Houston suburb launches innovation grant program to attract startups

innovation incentive

Think you’ve got a burgeoning startup? Consider moving it to southwest Houston. The City of Sugar Land announced the Sugar Land Starts Innovation Fund last week to support companies that move jobs to the area.

“The Sugar Land Starts Innovation Fund is designed to support companies that are ready to grow and make a meaningful, long-term commitment to our community,” Colby Millenbruch, business recruitment manager for the City of Sugar Land, said in a news release. “By focusing on revenue-generating startups and performance-based incentives, we are creating a clear pathway for innovative companies to scale while reenergizing existing office space.”

The performance-based, non-equity dilutive grant program is open to companies that demonstrate at least $250,000 in generated revenue or $500,000 in institutional backing from a bank or venture capital firm. They must commit to hiring or relocating at least three employees in Sugar Land for a minimum of three years and at an average salary of $61,240. Compliance will be verified through Texas Workforce Commission reporting.

The fund builds off the Sugar Land Plug and Play partnership to turn the city into an innovative technology hub.

Collaboration with the Silicon Valley-based startup incubator and accelerator on a physical location in southwest Houston has supported 22 startups and has raised $6.5 million in capital since it officially launched in Sugar Land last March. Companies located at the Sugar Land Plug and Play include Synaps, a browser-based design platform for architects, and Intero Biosystems, which produces miniature human organs for preclinical drug development.

In addition to direct funding and business space, both the new grant and the overall Plug and Play project facilitate meetings with Houston-area businesses like CenterPoint Energy.

This should not only bring new industries to Sugar Land, but also allow existing companies to expand outward as technological investors to create a web of new progress.

“This investment is about more than technology. It’s about creating an environment where innovation can take root, grow, and deliver lasting value for the Sugar Land community,” David Steele, director of Texas at Plug and Play, added in the release. “Sugar Land is setting itself apart by taking a long-term view, investing in founders, partnerships, and technologies that will define the next chapter of growth. We’re proud to partner with the city in building an innovation ecosystem that benefits both entrepreneurs and the broader community.”

Income study shows $100,000 salary goes further in Houston in 2026

Money Talk

A 2026 income study has good news for big earners in Houston: A six-figure salary goes further than it did last year.

A Houston resident's $100,000 salary is worth $84,840 after taxes and adjusted for the local cost of living, according to the new financial analysis from SmartAsset. That's about $1,500 more than Houstonians were bringing home last year.

The 2026 take-home pay is about 8 percent higher than it was in 2024, when the same salary had an adjusted value of $78,089.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities. The figure was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services). Cities were then ranked based on where a six-figure salary is worth the least after applicable taxes and cost of living adjustments.

Houston ranked No. 60 in the overall ranking of U.S. cities where $100,000 is worth the least. If the rankings were flipped and the cities were ranked based on where $100,000 goes the furthest, that places Houston in the No. 10 spot nationwide.

Manhattan, New York remains the No. 1 city where a six-figure salary is worth the least. A Manhattan resident's take-home pay is only worth $29,420 after taxes and adjusted for the cost of living, which is 3.10 percent lower than it was in 2025.

SmartAsset determined Manhattan has a 29.7 percent effective tax rate on six-figure salaries. Meanwhile, the effective tax rate on a $100,000 salary in Texas (based on the eight cities examined in the report) is 21.1 percent. It's worth highlighting that New York implements a statewide graduated-rate income tax from 4-10.90 percent, whereas Texas is one of only eight states that don't tax residents' income.

Oklahoma City, No. 69, is the U.S. city in the report where a $100,000 salary stretches the furthest. A six-figure salary is worth $91,868 in 2026, up from $89,989 last year.

This is the post-tax value of a $100,000 salary in other Texas cities, and their ranking in the report:

  • Plano (No. 27): $72,653
  • Dallas (No. 47): $80,103
  • Austin (No. 53): $82,446
  • Lubbock (No. 59): $84,567
  • San Antonio (No. 62): $86,419
  • El Paso (No. 67): $90,276
  • Corpus Christi (No. 68): $91,110
According to the report, getting some "financial breathing room" by making six-figures really depends on where someone lives and what their lifestyle is. For residents living in the 42 states that levy some amount of income tax, their take-home pay dwindles further."And depending on how taxes are filed, reaching a $100,000 income may push a household from the 22 percent to 24 percent marginal tax bracket," the report's author wrote. "Meanwhile, locations with high costs across housing and everyday essentials may be less forgiving to a $100,000 income."

Rice University partners with astronaut foundation to offer new STEM scholarship

space scholars

Rice University has partnered with The Astronaut Scholarship Foundation (ASF) to offer a new scholarship opportunity for junior or senior STEM majors, beginning this spring.

The prestigious Astronaut Scholarship includes up to $15,000, mentorship, networking and a paid trip to the ASF Innovators Symposium and Gala. The scholarship is funded by the James A. Lovell Jr. Family Endowment, in honor of the late American astronaut and founder of the ASF.

“This scholarship opportunity represents an exciting new avenue for Rice STEM students to synthesize their experiences in courses and research and their commitment to advancing the public good as leaders in their field,” Danika Brown, executive director for the Center for Civic Leadership at Rice, said in a news release. “We are so grateful to the Lovell family and to the foundation for investing in Rice students, and we are confident that the foundation will be impressed with our nominees and that selected students will have a life-changing experience as astronaut scholars.”

The Rice Space Institute and the Center for Civic Learning recently hosted the ASF at the Ralph S. O’Connor Building for Engineering and Science.

At the ASF event, Jeff Lovell—son of James Lovell, who commanded Apollo 13 and flew on Apollo 8—announced the scholarship aimed at Rice STEM students. Charlie Duke, who served as spacecraft communicator for the Apollo 11 Moon landing and as the lunar module pilot for Apollo 16, also spoke at the event.

The ASF awarded 74 scholarships to students from 51 universities across the U.S. last May.

The ASF awarded its first seven $1,000 scholarships in 1986 to pay tribute to the Mercury 7 astronauts. It has since awarded more than $10 million to more than 850 college students.

So far, only students from Texas A&M University and the University of Texas at Austin have received the scholarship in Texas.
