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."

more room at the Ion

The Ion has announced it will bring more coworking space to its facility.

The innovation hub in Midtown, which is owned and operated by Rice Management Company, expanded its partnership with Dallas-based Common Desk to the Ion’s fourth floor. The addition brings another 28,000 square feet of workspace to the building.

“When people work in an inspiring place that fosters community, going into work is exciting. The Ion’s experience with Common Desk proves it,” says Jan E. Odegard, executive director of the Ion. “This rapid expansion signals that the Ion is the place to be for growing organizations, and we will soon be releasing new programs that expand our value proposition for startups, investors, corporations, academic institutions, and the community.”

According to the release, Common Desk's Ion space — originally opened in August of 2021 — reached max capacity in less than a year and now has a waiting list. The new combined space will total 86,400 square feet of coworking space for Houston entrepreneurs.

"With RMC’s support, we created a thoughtful design, along with the amenities and memberships offered,” says Common Desk's Head of Real Estate Dawson Williams in the release. “One year later, this space in the Ion is a game-changer for Houston’s innovators. It’s exciting that we’re already expanding because so many rapidly growing companies want to be inside the Ion and experience everything it has to offer.”

Founded in 2012, Common Desk has grown to over 20 locations and counting in Dallas, Houston, Austin, Wilmington, and Raleigh. In Houston, the company has opened coworking space in several locations, most recently at the POST in downtown.

A few years ago, Rice Management Company saw an opportunity a few years back to make an investment in Houston's nascent innovation and tech ecosystem, and announced the plans for the Ion, a 266,000-square-foot innovation hub in an renovated and rehabilitated Sears.

"In some ways innovation is not necessarily about creating something completely new — it's oftentimes building upon something that exists and making it better," says Sam Dike, manager of strategic initiatives at Rice Management Company, on the most recent episode of the Houston Innovators Podcast. "I think that's what we've done with the building itself.

"We took something that had really strong bones and a strong identity here in Houston," he continues, "and we did something that's often atypical in Houston and preserved and repurposed it — not an easy logistical or financial decision to make, but we believed it was the best for Houston and for the project."

What Houston can expect from its rising innovation district

Houston innovators podcast episode 140

Last month, the Ion Houston welcomed in the greater Houston community to showcase the programs and companies operating within the Ion Innovation District — and the week-long Ion Activation Festival spotlighted just the beginning.

The rising district — anchored by the Ion — is a 16-acre project in Midtown Houston owned and operated by Rice Management Company, an organization focused on managing Rice University's $8.1 billion endowment.

"We're chiefly responsible for stewarding the university's endowment and generating returns to support the academic mission of the university," says Samuel Dike, manager of strategic initiatives at RMC, on this week's episode of the Houston Innovators Podcast. "Part of those returns go to support student scholarships and student success — as well as many of the other academic programs."

"The university sees a dual purpose behind the investing," Dike continues, in addition to focusing on generating returns, RMC's mission is "also to be a valuable partner in Houston's ecosystem and pushing Houston as a global 21st century city."

RMC saw an opportunity a few years back to make an investment in Houston's nascent innovation and tech ecosystem, and announced the plans for the Ion, a 266,000-square-foot innovation hub in an renovated and rehabilitated Sears.

"In some ways innovation is not necessarily about creating something completely new — it's oftentimes building upon something that exists and making it better," Dike says. "I think that's what we've done with the building itself.

Now, the Ion District includes the Ion as the anchor, as well as Greentown Houston, which moved into a 40,000-square-foot space in the former Fiesta Mart building, just down the street. While RMC has announced a few other initiatives, the next construction project to be delivered is a 1,500-space parking garage that will serve the district.

"It is not your typical parking garage," Dike says. "The garage will feature a vegetated facade with ground-floor retail and gallery space, as well as EV charging spaces and spaces to feature display spaces for future tech. It's going to be a nice addition to the district."

The new garage will free up surface parking lots that then will be freed up for future construction projects, Dike explains.

He shares more about the past, present, and future of the Ion and the district as a whole on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

ExxonMobil named founding partner of Houston innovation hub

new collab

A Texas energy giant has joined The Ion as a founding partner, the innovation hub announced recently.

ExxonMobil, which announced its new Houston HQ move from Irving, Texas, earlier this year, celebrated the announcement at the Ion Activation Festival last month. The partnership is effective immediately, according to a June 13 news release.

“ExxonMobil has been a leader in energy technology for over a century. Collaboration is essential to both augment our capabilities and accelerate the development of scalable solutions,” says Linda DuCharme, president of ExxonMobil Technology and Engineering Company, in the release. “Our partnership with The Ion will enable us to tap into the extraordinary talent in Houston.”

ExxonMobil joins existing Ion founding partners Aramco, Chevron Technology Ventures, Baker Botts, and Microsoft, as well as affiliate partners bp and Intel. The company joins the Ion "to help develop solutions for the world’s emerging energy issues," per the release.

“To have one of the strongest brands in oil and gas globally join us is a testament to the Ion’s momentum and mission,” says Jan E. Odegard, executive director of the Ion. “We’re thrilled to welcome ExxonMobil’s thought leaders and this caliber of mindshare to the Ion family. As the Ion expands its programming and footprint, we are confident in the impact we’ll create together.”

The Ion is a 266,000-square-foot building developed and managed by Rice Management Company and anchors the 16-acre Innovation District in Midtown.

Houston's emerging innovation district gets global recognition from prestigious program

tech hotspot

The Ion Houston has a new feather to add to its cap. Rice Management Company's Midtown innovation hub has been recognized on a global scale.

The Global Network of Innovation Districts has added The Ion District to its network of innovation hubs, and the Ion is the first district in Texas to join. Affiliated with the Brookings Institute, the global organization consists of thought leaders and innovation district developers. With the addition of the Ion, there are 22 members in the Global Network, including the Pittsburgh Innovation District, Cortex Innovation Community in Missouri, Tech Central in Sydney, and Knowledge District Zuidas in Amsterdam.

“GIID’s Global Network is utilizing best practices of world-renowned innovation districts to accelerate regional economies. Their focus on placemaking, startup services, and community engagement are some of the critical components that lead to successful districts,” says Bryson Grover, investment manager of real estate development at Rice Management Company, in a news release. “With GIID, we will continue to think creatively about how the built environment and specialized programming can inform future development and allow equitable access to an ever-changing workforce.”

The Ion, a 266,000-square-foot space in the renovated Midtown Sears building, is the anchor of the district, which also includes Greentown Labs. According to the release, the next building is under construction, with three more projects to begin in the next year. Overall, the build-out of the Ion District will deliver three million square feet of development across 16 acres over the next decade.

“The Ion and the Ion District represent a major commitment and investment in the success of Houston as a center of innovation and a foundation of Houston’s economic future. From the very beginning of our planning, we visited innovation hubs and districts around the country and around the world to make sure that we drew on their experiences and best practices,” says Rice President David Leebron in the release. “And by participating in the Global Network now, the Ion District will contribute to and benefit from a global exchange of knowledge among the very best innovation districts, which complements Rice’s broader international engagements and strategies.”

GIID is a nonprofit dedicated to research on and connecting innovation districts in new geographies of innovation, per the release. Headquartered in New York, the organization was founded in 2018 to help position innovation districts as engines of economic development and spur productive, inclusive, and sustainable environments.

“We’re thrilled for The Ion and Ion District to join our network, especially as it commences its next steps on development later this year,” says Julia Wagner, president of GIID, in the release. “Our team has extensive experience working with unique real estate ventures that aim to transform how communities learn, work, and live. We look forward to playing a part in Houston’s transformation, and as we have documented in innovation districts around the world, having a leader like Rice drive the creation of the district is a key ingredient of its continued and growing success.”

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
