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 innovation hub expands coworking space

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."

Greentown Labs announced that it has appointed Barbara J. Burger — former vice president of innovation and president of Chevron Technology Ventures, Chevron's startup investment arm — to its board of directors.

In her previous role at Chevron, she spearheaded the energy company's support of Greentown Labs since 2013 and the opening of its Houston incubator. After announcing her retirement in December, she has continued being active at Greentown and hosts semi-annual Women of Greentown Houston dinners.

“I am honored and excited to join the Greentown Labs Board of Directors,” says Burger in the release. “Combatting the effects of climate change requires bringing a wide range of innovative solutions to scale. There is work for incumbents and startups alike in this enormous challenge that WE all face. Greentown Labs plays an essential role in providing facilities, tools, programs, and an inclusive community to nurture and grow innovation that matters.” Click here to continue reading.

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.

"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."

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.”

5 Houston deep tech startups pushing the boundaries of their industries

meet the finalists

Houston has long been at the forefront of innovation, from NASA’s Johnson Space Center to its startup ecosystem using technology to disrupt industries.

As part of the 2026 Houston Innovation Awards, our Deep Tech Business category will honor an innovative startup providing technology solutions based on substantial scientific or engineering challenges, including those in the AI, robotics and space sectors.

Five deep tech companies have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
