Houston innovators talked big topics at SXSW 2024 — from the startup scaling and converging industries to the future of work.

Houston House, which was put on by the Greater Houston Partnership on March 11, hosted four panels full of experts from Houston. If you missed the day-long activation, here are some highlights from the experts who each commented on the future of the Bayou City when it comes to startups, technology, innovation, and the next generation's workforce.

"When we think about Houston, we think about access to at-scale infrastructure, amenities, and workforce and talent pools."

— Remington Tonar, co-founder and chief growth officer at Cart.com, says about why the company chose to return its headquarters back to Houston last year. One of these amenities, Tonar explained, is Houston's global airports.

"If New York and Austin had a baby, it would be Houston, because you have friendly people with a big-city culture."

— Mitra Miller, vice president and board member of Houston Angel Network, says, adding that Houston has a cost efficiency to it, which should be at the forefront of founders' minds when considering where to locate.

"We are not only attracting global talents, we are also attracting global wealth and foreign investments because we are the rising city of the future. We are the global launch pad where you can scale internationally very quickly."

— Sunny Zhang, founder of TrueLeap, says adding how there's a redistribution of global workforce happening when you consider ongoing global affairs.

"We overwhelmingly as a company, and my co-founder would agree, knew we had to go the Houston path. And we started funneling a lot more resources here."

— Carolyn Rodz, co-founder and CEO of Hello Alice, says, explaining that the pandemic helped equalize the talent across the country, and this has been to the benefit of cities like Houston.

"Houston is here with arms open, welcoming people and actively recruiting."

— Sean Kelly, co-founder and CEO of Amperon, says, emphasizing how Texas has made moves to being business friendly. Amperon was founded in New York, before moving to Houston a couple years ago.

"There is a revolution starting to happen in Houston right now."

— Trevor Best, co-founder and CEO of Syzygy Plasmonics, says, first commenting on the momentum from Rice University, where his company's technology originates from. But, as he adds, when you compare the ecosystem when the startup was founded in 2019 to where it's at now, "there is so much more happening."

"Houston has a critical mass in terms of aerospace."

— Stephanie Munez Murphy of Aegus Aerospace says, saying specifically that NASA's Johnson Space Center holds some responsibility for that. "JSC is the home of opening up space commercialization."

"There's diversity in industries people are coming from, but also in terms of experience and expertise that (Houstonians) have."

— Robyn Cardwell of Omniscience says, adding that Houston's diversity goes further than just where people originate from. "Houston has all these pieces put together ... for growing and scaling organizations," she adds.

"I've worked with thousands of students in Houston who are actively looking to better themselves and grow their career post college or post high school and go into the workforce."

— Allie Danziger of Ascent Funding says, adding that Gen Z, which is already entering the workforce, is entrepreneurial and ready to change the world. "Seeing the energy of Houstonians is just thrilling," she adds.

"We're working together in the Houston community. ... There are so many opportunities to collaborate but we need conveners." 

— Stacy Putman of INEOS says, adding that within industry there has been a lack of discussion and collaboration because of competition. But, as she's observing, that's changing thanks to conveners at colleges or at the Greater Houston Partnership.

"The opportunity for Houston is that everybody has to step up to be in some way, shape, or form helping us with this."

— Raj Salhotra of Momentum Education says about supporting the future workforce of Houston, including low-income household students.

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.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups 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.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

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.
