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."

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.
