Houston VC firm closes $21M fund for underrepresented founders

fresh funding

Houston-based South Loop Ventures recently closed its debut fund for more than $21 million, led by investments from Rice Management Company and Chevron Technology Ventures.

The funds will go toward teams with at least one underrepresented founder of color working in the energy, health, space, sports and fintech sectors. Additional investments came from The Great Commission Foundation of the Episcopal Diocese of Texas, Texas CapitalBank and others organizations.

According to South Loop Ventures, less than 3 percent of venture capital reaches underrepresented founders of color. Zach Ellis Jr., founder and general partner of South Loop, says the firm wants to address this "billion-dollar blind spot."

"Inequitable distribution of venture capital represents a clear market inefficiency—and market inefficiencies translate into exceptional opportunities," Ellis said in a release.

He added that the firm's location in Houston will help it make an impact.

"Being anchored here gives us front-row access to world-class corporations eager to engage and support innovation from founders with underrepresented voices and perspectives," he added in the release.

Ellis founded South Loop Ventures in 2022. It has funded 13 companies since August 2023 and plans to fund several more this year. Its portfolio includes Houston-based Milkify, a breast milk freeze-drying service; Lokum App, a Houston-founded platform for recruiting certified registered nurse anesthetists; and others.

Ellis' background spans the United States Military, academia, and roles at Rev1 Ventures and PepsiCo’s corporate venture team. He previously told InnovationMap that he was called to invest in founders of color after George Floyd's murder. He says he also realized how much money was being left on the table by overlooking these innovators.

"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," he said on the Houston Innovators Podcast in 2024. "A big part of our mission is also to help catalyze Houston as an ecosystem for tech entrepreneurship."

Houston innovator raises pre-seed funding for health care staffing platform

just closed

A Houston health care innovator is celebrating an oversubscribed round of pre-seed funding to improve on her startup's unique staffing platform.

Ayoade Joy Ademuyewo founded Lokum last year to create a solution to better connecting medical specialists with health care facilities nationwide. The new platform, which cuts out the middleman and lowers staffing costs, raised $700,000 in pre-seed funding that will go toward further development of the technology.

"Healthcare organizations spend $26 billion annually to support a crippling dependence on third-party agencies for connecting with clinical staff," Ademuyewo says in a news release. "Technological solutions that are pointed precisely to streamline and strengthen the relationships between highly specialized clinicians and their future employers are vital to alleviating this detrimental dependance, and central to our mission.

"I'm incredibly proud to have earned the trust of my colleagues, investors, team, and mentors in solving this complex problem."

Ademuyewo raised the round with support from local investors, including Aileen Allen, an adviser and investor associated with the Houston Angel Network, Mercury, and The Artemis Fund; and Matt Miller, former Liongard product executive, as well as from Houston-based VC firm South Loop Ventures. Techstars and JP Morgan also contributed to the round.

"Lokum has found a way to disrupt an organically inefficient and expensive market with an elegant solution that doesn't just save hospitals time and money, but also increases the pool of specialty providers in a market that is consistently strapped for such expertise," Jerry Varnado, venture partner at South Loop Ventures, adds. "This is what disruption in healthcare looks like — scalable commercial solutions that contribute towards better patient care, and we're happy to be part of Lokum's journey."

Ademuyewo has the idea to start Lokum after her experience as an independent contract nurse anesthetist amid the height of the pandemic as she witnessed third-party recruitment agencies take advantage of medical professionals like herself.

Now, the platform's early pilot, which focuses on clinicians in anesthesiology, has served clients across nearly 200 hospitals and surgery centers in 20 states. Ademuyewo also participated in 2024’s cohort for the Google for Startups Accelerator Program-North America, where she spent 10 weeks developing and building her company and platform.

3 Houston innovators to know this week

who's who

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.

Zach Ellis, founder and managing partner of South Loop Ventures

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."

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."

Texas A&M, UH rise in global rankings of universities attracting the most attention

visibility report

Houston and Texas universities had a strong showing on the 2026-27 Global University Visibility (GUV) Rankings compiled by D.C.-based higher ed market research firm American Caldwell.

Texas A&M ranked No. 6 on the list—the top rank of any Texas university. Meanwhile, the University of Houston ranked No. 52, a 15-spot jump from its previous ranking.

The GUV rankings rate colleges that garner the most global attention via news coverage, social media influence, website traffic, YouTube views, and general public interest. GUV evaluated over 1,200 universities across 193 United Nations-recognized countries.

Texas A&M, with its No. 6 global ranking, also claimed the No. 5 spot among U.S. institutions. The university climbed 21 spots from its previous rank.

“News mentions were a driver of Texas A&M’s movement in this year’s rankings, and earned media remains one of the strongest signals of relevance,” Tim Doty, associate vice president for earned media at Texas A&M, said in a news release. “Much of that visibility begins with our faculty and research experts, whose work helps explain, solve and give context to issues people care about. When Texas A&M experts appear in news stories about research, discovery, national security, agriculture, health, engineering, service and the future of Texas, audiences see the university not only as large or well known, but as useful, relevant and necessary to the conversations shaping our state and country.”

In the “Public Interest” category, UH also claimed a top 10 global ranking at No.6. UH touts its overall GUV rankings success to Guggenheim Fellowships, MacArthur “Genius” grants, National Academy membership, studies like researchers breaking the superconductivity temperature record, and success on the football field and basketball courts.

“Across the board, there is no question that the University of Houston is a brand on the rise,” Shawn Lindsey, interim vice president for marketing and communications, said in a news release. “People are seeing our story, hearing about the amazing things happening at UH and actively seeking us out to learn more. We are seeing it in record-high student applications, we are seeing increases in trademark licensing revenue, our faculty are earning global accolades. It’s an exciting time to be a Houston Cougar.”

Other Texas institutions to make the top 250 on the list include:

  • No. 22 The University of Texas at Austin
  • No. 104 University of Texas at Dallas
  • No. 159 Texas Tech University
  • No. 178 Rice University
  • No. 191 University of North Texas
  • No. 248 Texas State University

For the fourth year in a row, Harvard University secured the top spot on the list, followed by MIT, Stanford University and Purdue University. The University of Oxford was the top non-U.S. institution at No. 5.

Astrodome group seeks new ideas for future of historic Houston landmark

8th Wonder News

The Astrodome may have once been touted as the Eighth Wonder of the World, but its current condition remains one of Houston's most famous follies. In an effort to find a better use for the iconic building, The Astrodome Conservancy has released a Request for Information (RFI), inviting proposals from interested parties on how the historic landmark might be used in the future. Respondents have until September 8 to submit their responses at the official conservancy site.

“This RFI is an opportunity for the market to help shape a shared vision for the Astrodome,” said Beth Wiedower Jackson, executive director of the Astrodome Conservancy, in a release. “We are looking to gather creative, feasible, and financially viable ideas that reflect both the significance of the Astrodome and its potential as a catalyst for future development.”

When the Astrodome opened in 1965, it was a marvel of engineering and the world's first air-conditioned, multi-purpose domed sports stadium. It remained an iconic part of Houston until changing trends in sports sent the Astros and the Houston Livestock Show and Rodeo to newer stadiums with modern amenities. After the 2003 rodeo, the dome was closed, except for a brief use as an evacuation shelter for Hurricane Katrina.

A decades-long fight over what to do with the Astrodome followed that closure. The City of Houston condemned the building for various code violations in 2009. Fully renovating it would cost over $700 million — a tall order for taxpayers. Demolishing it would be far cheaper (around $55 million), but its status on the National Register of Historic Places makes that virtually impossible. Meanwhile, Harris County pays hundreds of thousands of dollars a year to maintain the building.

Proposals for the space have run the gamut. In 2024, the Astrodome Conservancy proposed Vision: Astrodome, which would transform the building into an indoor mall and event space. That still appears to be the foundation of the plan according to the RFI.

The RFI is seeking private investment to partner with the Harris County property. Proposals are merely for planning purposes and will not automatically lead to contracts for development. Section 2.3 states that participants in the new mixed-use space will "require back-of-house infrastructure improvements to support reliable operations at scale," likely meaning that the plan is to fund some of the much-needed renovations via tenants. However, the RFI points out that participants in the revitalized Astrodome will also be eligible for historic space preservation tax credits.

While Vision: Astrodome seems committed to using the stadium as a public space for the entertainment of Houstonians, the RFI is clear other options are on the table.

The Astrodome possibly being used to house a data center is specifically mentioned, though the RFI mandates such a proposal would need to be very upfront about the infrastructure demands and continuing operating costs of such a project. Public backlash against data centers led to Governor Greg Abbott ordering a pause on grid connections to them pending further review.

"The Astrodome presents a unique opportunity for adaptive reuse and redevelopment that honors its legacy while positioning it for long-term community and economic impact," said the conservancy in the release announcing the RFI.

Houston lands $14M in latest CPRIT grants to advance cancer, lab-on-chip research

cancer funding

Thanks to a $4 million grant from the Cancer Prevention and Research Institute of Texas, the University of Houston has recruited a top-tier researcher developing AI-powered lab-on-a-chip technology for early cancer detection.

Tianhong Cui, a professor of mechanical engineering at the University of Minnesota Twin Cities and an adjunct professor of physiology and biomedical engineering at the Mayo Clinic, specializes in microelectromechanical systems and advanced manufacturing at microscale and nanoscale levels. In addition to lab-on-a-chip systems, Cui focuses on biosensors and water sensors.

Lab-on-a-chip devices deliver big results in a tiny package

The CPRIT grant supports Cui’s development of a microscale lab-on-a-chip system for early cancer detection and post-therapy monitoring.

“Lab-on-a-chip technology crams an entire lab’s worth of functions into a tiny device roughly the size of a USB stick,” according to Built In.

Common uses for the technology include medical diagnostics, point-of-care testing, and environmental monitoring.

Lab-on-a-chip work being carried out at UH and elsewhere in Houston promises to revolutionize cancer detection and treatment. For instance, Houston biotech company iBiochips, a spinout from the Houston Methodist Research Institute, makes lab-on-a-chip devices that bolster cancer detection and therapy.

Four local organizations gain $10 million in CPRIT grants

Four other Houston-area organizations received an additional $10 million in grants in CPRIT’s latest round of funding:

  • University of Texas MD Anderson Cancer Center received two $2 million grants to recruit researchers Zheqi Li of Harvard University’s Dana-Farber Cancer Institute and Nikolaos Koundouros of Weill Cornell Medicine.
  • Rice University received one $2 million grant to recruit researcher Maria Akoppyan, formerly of the University of Southern California.
  • UT Medical Branch at Galveston received one $2 million grant to recruit researcher Cristina Santarossa of Johns Hopkins University.
  • Houston-based biopharma company Pulmotect received one $2 million grant to support better outcomes for cancer patients by activating immunity in the lungs as a first line of defense against germs.

The funding was part of $35 million in new CPRIT grants for institutions and companies across Texas approved at the organization's most recent meeting. To date, CPRIT has awarded more than $4.2 billion in grants.

“These awards support research across the cancer continuum from prevention to new classes of therapeutics,” said Dr. Scott Hiebert, chief scientific officer of CPRIT, said in a news release. “The work of these investigators will impact the lives of Texans across the state.”
