Houston-based Persona AI announced the expansion of its operations at the Ion and a major milestone in deploying its humanoid robots.

The company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the Ion, and is slated to begin expansion in June.

“We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” CEO Nicolaus Radford said in a news release. “This is where Houston’s tech future is being built. It’s a convergence point for the people, energy, and ideas that power our mission to redefine human-machine collaboration. For an industrial, AI-driven robotics company, there’s no better place to scale than in the heart of Houston.”

Persona AI’s new development center will be located in the suite utilized by the Ion Prototyping Lab, managed by TXRX Labs. The IPL will transition its operations to the expanded TXRX facility in the East End Maker Hub, which will allow the lab to grow its team and meet increased demand.

At the start of the year, Persona AI closed $25 million in pre-seed funding. Earlier this month, the company announced a memorandum of understanding with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

The project will deliver prototype humanoids by the end of 2026, with field testing and full commercial deployment scheduled to begin in 2027.

"As heavy industry faces growing labor constraints—especially in high-risk trades like welding—the need for rugged, autonomous humanoid robots is more urgent than ever,” Radford added in a separate statement. “This partnership with HD Hyundai and Vazil is more than symbolic—deploying to the shipyard is one of the largest real-world proving grounds for Persona's tough, humanoid robots.”

new to hou

A new 300,000-square-foot innovation and manufacturing hub with a goal of creating 1,000 new companies in the next five years has officially celebrated its grand opening.

The East End Maker Hub — a $38 million public-private partnership — is anchored by TX/RX Labs, a makerspace nonprofit, and located at 6501 Navigation Blvd. So far, 25 companies have signed leasing agreements with the hub that has two of its three phases completed.

"Houston can become the next great manufacturing hub in America," says Roland von Kurnatowski, president at TX/RX Labs. "We can decrease our external reliance and increase our resilience."

The grand opening event, which was held June 3, was attended by makers, EEMH tenants and employees, and some of the local politicians that aided in making the hub a reality with grants, private funding, and more.

"We've always been a city of amazing innovation, whether it's been in energy, medicine, or space exploration," says Mayor Sylvester Turner. "And, we've led the world in whatever we have chosen as the pursuit of our endeavors. One thing about this city is that when we work together, we win."

"The East End Maker Hub provides an opportunity to reclaim our history of innovation and manufacturing and to ensure that the process of innovation is equitable," Turner continues. "It is not saying much to be diverse if you are not inclusive at the same time."

Through TX/RX and other tenants, the EEMH will aim to provide education, workforce development, jobs, and entrepreneurial space to innovators, students, and more.

The mission of the East End Maker Hub is to "drive advanced manufacturing by bringing together the brightest engineers, scientists, manufacturers, and makers to generate innovative advanced manufacturing solutions," according to Patrick Ezzell, president of the Urban Partnerships Community Development Corporation.

Six Houston startups recently announced their moves into the space, and the EEMH tenants represent everything from 3-D printing and unmanned aerial vehicles to vodka distilling and fragrance design.

3D-printing startup to move into rising Houston innovation and maker hub

moving around Hou

The East End Maker Hub has landed perhaps its most intriguing tenant thus far — a Houston startup that makes 3D-printed human organs.

Volumetric Biotechnologies Inc. has leased 11,200 square feet at the East End Maker Hub to serve as its headquarters and manufacturing center. Jordan Miller, co-founder of Volumetric, says one of the benefits of being located at the hub will be access to a cleanroom operated by Alchemy Industrial, a 3D manufacturer of medical devices. Earlier this year, Houston-based Alchemy leased more than 5,400 square feet at the East End hub.

Volumetric will occupy space in the first phase of the 307,000-square-foot project East End Maker Hub. That phase of the $37 million project is set to open soon. The startup's current 5,000-square-foot headquarters is at 7505 Fannin St., near the Woman's Hospital of Texas and south of the Texas Medical Center.

Miller says Volumetric's new home will help it "maintain and accelerate our already breakneck progress." Volumetric's 12 biological, chemical, mechanical, and electrical engineers focus on producing human organs and tissues like the liver, kidney, pancreas, lung, and heart using a mix of medical-grade plastics and human cells.

"We're straining to scale our company as fast as our team is inventing and progressing our technologies. It's an absolutely wonderful problem to have," Miller says.

Volumetric hopes to commercialize its 3D-printed organs in 2021. Founded in 2018, Volumetric is a privately held spin-out of Rice University's Department of Bioengineering. It has received $1.8 million in funding, according to Crunchbase. Investors include Silicon Valley-based Sand Hill Angels, and the Springfield, Virginia-based Methuselah Foundation and Methuselah Fund.

Local Realtor Mike Pittman, a development associate with Pearland-based project partner Urban Partnerships Community Development Corp., recruited Volumetric to the hub. He says he's also working with a distillery, a coffee roaster, and a medical gown manufacturer on leasing space there.

Once the East End Maker Hub opens, Houston's East End District will be home to the largest maker hub in Texas and one of the largest such facilities in the U.S. Being built in three phases on a 21-acre site at 6501 Navigation Blvd., the East End Maker Hub aims to create an environment that gives members of the community access to trade skills and career opportunities, and to provide businesses a place for innovation and manufacturing. The hub's second and third phases are on track to be finished in 2021.

The soon-to-open first phase will feature "white box" suites, ranging in size from 420 square feet to 20,000 square feet, that cater to three sectors:

  • Innovation (robotics, 3D printing, and R&D)
  • Crafting (ceramics, fine woodworking, and screen printing)
  • Light fabrication (food production).

Aside from Alchemy, tenants recently lined up for the hub include Houston-based Waste Management Inc., whose R&D team will occupy more than 3,500 square feet, and Houston-based construction technology company Rugged Robotics Inc., which is renting 1,700 square feet.

"We're not the place for software companies, but our innovation area is the place for hardware companies — those that are into drones, robotics, 3D printing," Pittman says.

The project's hardware innovation element could boost Houston's manufacturing economy, he says. A recent analysis by the Smartest Dollar website found that 7.5 percent of the Houston metro area's workforce is employed in manufacturing. From 1999 to 2019, the number of manufacturing jobs in Houston grew by just 1.9 percent.

So far, the nonprofit TXRX Labs makerspace is the hub's largest tenant, having signed a lease for 65,000 square feet in the first phase. TXRX Labs and Urban Partnerships Community Development teamed up to develop the hub. TXRX contributed $1.25 million in equity, and Urban Partnerships Community Development raised $35.75 million in capital.

Houston-based Stewart Builders is the general contractor for the East End Maker Hub, and Houston-based Method Architecture is the architect of record.

Aside from supplying room for businesses and nonprofits to grow, the hub seeks to provide training and jobs for local residents. Pittman says the hub — located within a tax-advantaged Opportunity Zone — encourages its tenants to hire people who live within a three-mile radius.

"You don't have to go and get a Ph.D. in nuclear science for these jobs to be able to attain really good wages for your family," he says.

Houston nonprofit makerspace seeking donations as it prepares to move into its new home

Calling for cash

With grants and public funds secured, Houston-based TXRX Labs as one last round of fundraising to acquire before it's ready to head full-speed ahead into its new location.

TXRX launched a $85,000 fundraising campaign to help get the organization where it needs to be before it moves into its 60,000-square-foot space in the East End Maker Hub in spring or summer of next year. The organization, along with its sister nonprofit, Urban Partnership Community Development Corp., has been selected by the city of Houston for an $18 million award and by the federal government for a $5 million innovation grant.

"In the last two weeks, we were getting close to finalizing funding for the building and came up short," says Lauren Caldarera, development director at TXRX. "We wanted to reach out to our membership at TXRX and the broader Houston community to help see if people will help support this unique offering for Houston."

In order to receive those grants, TXRX needs to submit design materials — a process that they budget to cost $325,000. (TXRX has already procured $240,000.) An anonymous donor agreed to match donations, and the organization has until the end of May to raise. Anyone can donate online.

TXRX is focused on bringing back Houston's East End as a manufacturing hub. As manufacturing jobs left the second, third, and fifth wards, it's created a need for skilled labor, middle class jobs, says Roland von Kurnatowski, executive director of TXRX.

"We're looking to bring together innovative companies in the physical innovation space into the East End and creating these middle class jobs," says von Kurnatowski. "It's a modern approach to combating economic inequalities instead of providing handouts."

TXRX is already making a dent in their mission with their smaller space. The organization has over 400 members and incubates 20 or so companies. The new space will allow TXRX to incubate almost twice that amount, work with 75 companies who need prototyping and manufacturing services, and grow their classes and educational offerings.

"Having this space is critical as Houston moves forward in creating an innovation ecosystem," Caldarera says. "We need a space for people to develop their physical prototypes, have engineers and other experts to coach and mentor them, and create more startups and innovators here."

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.
