Next week, Houston Exponential's annual week of innovation and networking is taking place. Here are five things you need to know before you go.

1. New year, new name.

Houston Tech Rodeo, which originated in 2020, has been rebranded to H-Town Roundup, but the week of innovation and entrepreneurship still has the same goal of providing programming and events that connect and educate Houstonians.

On a recent episode of the Houston Innovators Podcast, Natara Branch, CEO of Houston Exponential, says the change is meant to make for a more inclusive experience for entrepreneurs of small businesses, something she's seen a need for since she took on her role last year.

"This year, we've had the better part of a year to think about what can be different and how can we serve the founder," she says.

Branch explains that some members of the Houston community confused the event for being associated with the Houston Livestock Show and Rodeo or for being only for true tech people. Branch says the wanted to open the door a little wider to entrepreneurs who are innovative without necessarily working in technology.

"That's not what we wanted — to exclude anyone," she says. "H-Town Roundup is going to allow us to be more inclusive."

2. It's completely free to attend.

Dozens of events are taking place around town, and all are free to Houston entrepreneurs, investors, and more. Simply register for anything you're able to attend.

For reference, a full, detailed agenda is available online too.

3. There are two featured events.

International workspace company announces 2 more Houston coworking spots

Space(s) city

An Amsterdam-based coworking company is doubling down on Houston with the announcement of over 120,000 square feet to deliver before the end of the year.

Spaces, which first entered the Houston market with the 2017 announcement of its Kirby Grove lease, will be opening new locations in CITYCENTRE and GreenStreet, according to a news release. All three properties are owned and operated by Midway Properties.

"Spaces is redefining the way work is done, providing a contemporary, social and creative environment with a real focus on community," says Michael Berretta, vice president of Network Development, for IWG, which owns Spaces, in the release. "Houston is a vibrant city with a global business hub and an entrepreneurial attitude. Spaces gives Houston's talent pool an inspiring place to work and meet with other people who believe in the power of collaboration to drive a business forward."

Spaces has over 3,300 flexible workspace locations across the world. There are three locations open in Texas — the other two being in the Dallas area. In addition to the two expected Midway properties, a third location in Two Post Oak Central is expected to deliver in 2019, the Houston Business Journal reports.

The GreenStreet location in downtown Houston will have 63,000 square feet of workspace in repurposed retail space. Among the features promised are open space, smaller team rooms, private offices, phone booths, and a 3,000-square foot rooftop patio.

The news of the workspace follows closely behind an international accelerator program, MassChallenge, announced its Houston program in GreenStreet.

The CITYCENTRE workspace will take up almost 61,000 square feet of CITYCENTRE One and touts similar features and flexible space. Both locations also boast of existing shopping, dining, and entertainment perks in the centers.

"Spaces fits perfectly in GreenStreet, a mixed-use district that is being redeveloped as the new model of urban lifestyle,"sys Chris Seckinger, vice president and investment manager for Midway, in the release. "And CITYCENTRE gives Spaces an ideal platform to serve businesses, whether they are collaborating globally or locally, in the midst of West Houston's concentration of energy, technology and engineering firms."

Earlier this month, a report found that over the past two and a half years, Houston's coworking space has only grown marginally. With the announcement of Spaces' expansion — as well as The Cannon and The Ion projects — expected to deliver over the next two years, Houston stands to make up for lost times, so to speak.

Station Houston announces its transition into becoming a nonprofit

Cha-cha-changes

Houston's startup scene just got a little more accessible. Station Houston's stakeholders voted to transition the organization to nonprofit status from the C-corp status it currently holds.

The status change is effective January 1, 2019, for the acceleration hub, which is based in downtown Houston. The news was announced to its members in an email sent on December 13.

"Following in the footsteps of successful hubs such as 1871 in Chicago or Mass Challenge in Boston, we see that non-profit status allows these organizations to stay true to their missions while providing best-in-class services to members," reads the email. "We are excited to announce that this week, all Station stakeholders voted in favor of the conversion to non-profit status."

Station's CEO, Gabriella Rowe, tells InnovationMap that the announcement is part of a larger change for the organization, which will announce its plans for Station 3.0 in January.

"This opens up so many more funding and programing opportunities for us, so that we can charge our entrepreneurs and startups as little as possible and give them all the depth of services and support," Rowe says. "That's really what it comes down to."

Station Houston is among the partners — along with the Rice Alliance for Technology and Entrepreneurship — for the Houston innovation district that plans to open in the rehabilitated Sears building in Midtown. The space plans to open in 2020 and hasn't yet broken ground. Rowe discussed Station 3.0 and the district in an interview with InnovationMap in November.

"We're going to be doing a huge launch of Station 3.0 in January," she said in the interview. "It will really allow us to tell the world not just what we're going to be for the next three months, but what we're going to be over the next three years."

Station Houston recently hosted the Texas Digital Summit with Rice University and the Rice Alliance. The all-day summit consisted of panel discussions, keynote speakers, and a startup pitch of 39 companies. At the conclusion of the day, Rowe and Brad Burke from Rice announced 10 of the most promising startups from the summit. You can read about those companies here.

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.
