Midtown Houston's innovation hub has unveiled its latest building feature and named its operation partner for the space.

The Ion opened its The Ion Prototyping Lab with the announcement that Houston nonprofit TXRX Labs will be the operator of the lab. The IPL’s 6,500 square-foot space will include access to tools — such as laser cutters, CNC mills and lathes, electronics assembly equipment, and 3D printers — as well as programming, training, and support.

“The Houston community’s growing need for these services has led to our growth from a small community organization to a partnership with Houston’s leading center for innovation, The Ion,” says Roland von Kurnatowski, president of TXRX Labs, in a news release. “With our presence at The Ion and in its Prototyping Lab, we are able to join together innovative ideas and technology to create a social and collaborative space to support tomorrow’s entrepreneurs' needs and challenges.”

Founded in 2008 and based in the East End Maker Hub, TXRX Labs provides community-focused engineering and fabrication services and job training programs. The nonprofit's goal is to make Houston a major 21st-century manufacturing hub.

The new space within the 266,000 square-foot innovation hub was designed by Gensler and is "the largest open corporate and startup-aligned prototyping space in Houston," according to the release.

“As part of Gensler’s contributions to the development of The Ion, we strategically designed the Prototyping Lab to function as a dedicated space for innovators and entrepreneurs to collaborate,” says Vincent Flickinger, senior associate and design director of Gensler Houston. “The Ion Prototyping Lab is equipped with tools for prototyping robotics and other energy focused innovations and cultivates an entirely new way of doing business in a reimagined, historic building and with one of Houston’s fastest-growing innovators, TXRX. We look forward to introducing the IPL’s offerings to the public.”

The IPL is the latest opening for The Ion. Last summer, the hub, which is opened and managed by Rice Management Company, opened its coworking space. The next openings to expect are an investor studio and several restaurant concepts, including Late August, The Lymbar, and more. Common Bond On-The-Go, located on the main floor of the Ion, opened this week too.

“With its close proximity to Houston’s Central Business District and The Texas Medical Center, The Ion is thrilled to provide the Houston tech community the Prototyping Lab operated by TXRX as an essential resource for businesses,” says Jan E. Odegard, executive director of The Ion, in the release. “The Ion serves as a driver and convener of activity, while TXRX's successful model of hands-on training and technological innovation is being leveraged to jumpstart the activity of entrepreneurs, corporations, and researchers. You think it, we make it.”

Members will have daily access to the IPL from 9 am to 5 pm. The cost of the membership has not been announced, but IPL will offer grant opportunities, per the release. All members must first complete a safety and skills training course.

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.

Houston tech community answers the call for medical equipment amid coronavirus-caused shortages

in need of PPE

In the span of one day, the founders of Houston-based Lazarus 3D received calls from emergency room directors and physicians and vice presidents of hospitals explaining a dire need for personal protective equipment — like surgical masks and face shields — for medical professionals in the front lines of the battle against COVID-19.

"We stopped everything we were doing," says Jacques Zaneveld, co-founder of Lazarus, which makes 3D-printed human organs for surgeons to practice on. "We've moved 100 percent of our focus on developing PPE."

Now, Zaneveld with his co-founder, Smriti Agrawal Zaneveld, have manufacturing orders in for 700,000 surgical masks weekly and have designed a non-FDA approved face shield, which they have ordered a few million of. The duo has taken out a short-term loan to front the cost of the medical equipment and are now looking for the right customers to buy these new PPE products. All hospitals and medical professionals in need of supplies can head to Lazarus' website to request more info.

"Our personal feeling has been to do whatever we can do to build as many as possible," Jacques tells InnovationMap. "It's very stressful because I'm borrowing money that we don't have in order to set up these production lines."

On the other side of town, 3D printing nonprofit TXRX has reprogramed 30 of its 3D printers to make PPE. The nonprofit is working Memorial Hermann to quickly prototype and test items made with materials they can get their hands on.

The Center for Disease Control has relaxed some of the requirements for PPE in light of the crisis and shortage, and Roland von Kurnatowski, president at TX/RX Labs, says that has helped speed up their efforts. But, the biggest challenge, he says, has been to quickly get together a design and prototype for Memorial Hermann to give them feedback so that they can then produce the products.

"I think there are a lot of people out there producing devices, but I think the problem is there's not a lot of clarity around materials, quality, and acceptance. People are doing what they can with what they've got," says von Kurnatowski. "Our hope working with Memorial Hermann was to make sure we are devising and testing devices that are functional and appropriate.

TXRX is also relying on Memorial Hermann and others in the medical community to indicate which PPE devices are most needed. Currently, the nonprofit is printing 10,000 face shields for Memorial Hermann, but also has designs for N95 respirators, surgical masks, a positive air pressure respirator (or PAPR), Tyvek suit, and even a portable shield for the intubation process.

Von Kurnatowski says the Houston community can get involved by donating to TXRX's GoFundMe campaign. The 3D printing process is quick and local, but expensive and out of budget for hospitals, so TXRX is taking a loss on its products it is creating. The organization is also looking for people who might have 3D printing materials or experience to volunteer — TXRX has about 20 people working on this but hopes that number ramps up to 60 to 80 people helping out.

Crisis also brings the community together in their time of need — that's what Zaneveld says he sees happening.

"Everyone who is at all involved in the medical space in engineering in Houston is trying to put stuff out," Zaneveld says. "We're sharing information and trying to work together to support each other."

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.
