The Ion Smart and Resilient Cities Accelerator has named the five companies participating in its latest cohort, which starts next week.

Launched in 2019, the programing for the accelerator and its member companies focus on addressing the needs and challenges the city of Houston and other major metros are facing — including climate change. The five selected companies will start the 12-week program next week with a goal of securing a pilot with the city.

"We're thrilled to kick-off Cohort 3," says Christine Galib, senior director of programs at The Ion, in a news release. "The ISRCA remains a core asset in The Ion's Programs portfolio, since it enables recurring collisions, connections, and collaborations among startups, stakeholders, and subject-matter experts."

The selected startups are:

  • Phase Filter/Kinetic Synergies: The university-born startup has created an automatically changing air filter that works with existing HVAC systems to lower cost and energy use as well as eliminate the annoying chore.
  • Frakktal: In an effort to create a circular economy, Frakktal repurposes and reuses discarded polymer materials from the greater Gulf Coast region to also use in the same region.
  • Moonshot Compost: The company collects food waste from Houston residents and businesses via curbside pickup and drop-off while also collects and provides data on each pickup.
  • Teratonix: Using radio frequency (RF) electromagnetic from radio /TV broadcast, cell phone tower, wifi routers, and more, Teratonix provides solutions to generate electricity.
  • Smart Watts:The company taps into smart meter sensors to enable a personalized energy monitoring dashboard that provides users with data to make better energy use decisions.

"The ISRCA Cohort 3 will highlight companies that focus on making sure Houston is here for generations to come," says Courtney Cogdill, program manager for The Accelerator Hub at The Ion, in the release. "By activating the Houston innovation ecosystem and showcasing Houston's talent, Cohort 3 will spotlight Houston as a city committed to sustainability."

The previous cohorts of the program focused on resilience and mobility in Cohort 1 and cleantech for Cohort 2.

"As the world-at-large expands their mobility with social distancing restrictions lifted, it's important cities and businesses review their sustainability practices and carbon footprint and continue to improve upon the progress that's been made," says Jan E. Odegard, interim executive director of The Ion, in the release. "The Ion is excited to empower entrepreneurs who will play a critical role in improving sustainability. With Houston and our diverse and innovative industries as a backdrop, The Ion is prepared to address the challenges sustainability will face in a post COVID-19 world."

The program will be housed in The Ion, a 266,000-square-foot mixed-use structure, which is expected to open within the next few months, along with the organization's other accelerator programs.

The Ion's accelerators are working to bring out the best in Houston — from resiliency to diversity

HOUSTON INNOVATORS PODCAST EPISODE 71

When you look at the business accelerator programs offered at The Ion, a rising innovation hub in Midtown, you see Houston represented. From energy and space tech to resiliency and diversity, the four accelerators intentionally cover what Houston is all about.

Courtney Cogdill, program director of the Accelerator Hub, and Christine Galib, senior director, at The Ion joined the Houston Innovators Podcast to discuss what all they are focused on across the business accelerator programs at the hub. Editor's note: This podcast was recorded ahead of the winter storm that affected the state of Texas this week.

Now more than ever, innovators are dedicating their careers to resilient technologies that can enhance the city's future. And this effort comes naturally to Houstonians, Galib says on the podcast.

"There is an ethos here that is one of roll up your sleeves, collaborate, and get to work. Get the work done, and have fun while you're doing it," she says on the show. "We all come together in a time of challenge, and we really show each other that we're not just individually resilient, we are collectively resilient."

Neither Galib nor Cogdill are from Houston — but each have observed the same resiliency among the city and its people.

"Houston really just picks itself back up by the bootstraps and just runs," Cogdill says.

But The Ion Smart and Resilient Cities Accelerator, launched in 2019, was only just the beginning for The Ion's Accelerator Hub. Last year, three more accelerator programs were announced — the Aerospace Innovation Hub for Minority Business Enterprises at The Ion, Austin-based DivInc's Accelerator, and the Rice Alliance Clean Energy Accelerator. These were made possible through a series of grants — a $1.4 million one from NASA to launch the ASCI-Hub and a $1.5 million one from Economic Development Administration.

Galib and Cogdill discuss each of the programs, as well as what they are excited for when The Ion opens later this year. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Mayor Turner recognized nationally for progress of moving Houston toward resiliency

Turner's plans

In the past five years, six federally declared flooding disasters have wreaked havoc in Houston — most notably Hurricane Harvey in 2017. Now, you might say Houston stands tall as a hub of resilience when it comes to disaster preparedness and myriad other pressing issues.

The Texas chapter of the American Planning Association recently honored Mayor Sylvester Turner's Resilient Houston initiative as the top entry in the resilience category of the chapter's annual awards program. In addition, Turner was just named chairman of the Resilient Cities Network.

With backing from Shell Oil Co., the City of Houston hired its first chief resilience officer, Marissa Aho, in 2019 and developed a multibillion-dollar resilience strategy to address threats from hurricanes, tropical storms, floods, and climate change. The plan also seeks to boost the resilience of Houston's economy, neighborhoods and natural resources.

"Our efforts need to be bold, transformative, and aligned to achieve the outcomes Houstonians deserve," Turner said in unveiling the resilience plan in February. "Resilient Houston is a framework for transformative change that comes from thinking and acting together to build and grow Houston's long-term resilience. We will need our partners and every Houstonian at the table to achieve this vision."

Dallas and El Paso also have resilience plans in place.

Houston's resilience effort outlines a number of ambitious goals, such as:

  • Updating city building codes and standards by 2030 to reduce damage from disasters.
  • Attracting or incubating 50 Energy 2.0 companies in the Houston area by 2025.
  • Planting 4.6 million new native trees by 2030.
  • Building at least 375,000 homes in Houston for all income levels by 2050.
  • Providing all Houstonians with easy access to high-frequency public transportation by 2050.

As explained by Rice University's Kinder Institute for Urban Research, hurricanes and floods are examples of "acute shocks" in terms of resilience. These are sudden, large-scale events that disrupt and endanger life. Other shocks include economic crisis, cyberattacks, terrorism, chemical disasters, and extreme heat.

The Kinder Institute points out that Houston's resilience strategy not only addresses these shocks but also takes on "chronic stresses" that hamper recovery from these shocks. Those stresses include poor air quality, health disparities, crime, economic inequality, urban sprawl, and limited access to education.

"Stresses do not impact every Houstonian the same way," says the institute, which helped develop the Resilient Houston project.

Startups participating in Houston's Ion Smart and Resilient Cities Accelerator are tackling many of the same challenges that Resilient Houston is. The accelerator's second cohort launched in April with six startups.

Funded by Microsoft Corp. and Intel Corp., the accelerator "is committed to solving challenges Houstonians face every day," Christine Galib, director of the accelerator, said in an April release. "We connect participating startups with mentors, partners, and stakeholders so they gain access to the resources they need to build, validate, and scale their technologies. Together, we are building a safer, smarter, and more accessible city for all Houstonians."

Houston's push for resilience meshes with Turner's new role as chairman of the Resilient Cities Network. The network is a global city-led nonprofit that aims to "empower cities to help them build a safe, equitable, and sustainable future for all."

"The reach, achievements, and vision of the Resilient Cities Network are impressive. I'm honored to be part of an organization that supports the critical needs of vulnerable communities by implementing projects that address multiple shocks and stresses and are improving the lives of people," Turner says in a release.

Among other goals, the network strives to strengthen local economies and bolster local campaigns to combat climate change.

Supported by $1.8 million from Shell, the City of Houston joined the Resilient Cities Network in August 2018. Houston is the U.S. headquarters for Shell.

"A year after Hurricane Harvey, Houstonians can clearly say we didn't let the storm get the best of us. Nevertheless, there's still work to be done across a wide range of challenges that we share as a community," Bruce Culpepper, who then was president and U.S. chairman of Shell, said in a 2018 release about his company's backing of Resilient Houston.

"Building long-term resiliency is much more than disaster response," Culpepper added. "It's about enabling the people of our city to thrive."

The Ion receives $1.5M economic development grant to go toward Houston accelerator programs

accelerating accelerators

The Ion — a rising hub for innovation being developed in Midtown by Rice Management Company — has received a $1.5 million grant to go toward supporting its startup accelerator programs.

The grant from the Economic Development Administration is a part of the organization's Build to Scale (B2S) program and will also benefit three accelerators: the Ion Smart and Resilient Cities Accelerator, the Rice Alliance Clean Energy Accelerator, and DivInc Accelerator.

"Receiving this grant is a big win for our city — furthering the Ion's opportunity to bring together leading minds to solve some of our toughest challenges," says Brad Burke, managing director of the Rice Alliance, in a news release from Rice. "We believe that it's a fully collaborative approach that will lead to accelerating energy innovation and sustainable solutions."

All three of these accelerators will be represented in The Ion's Accelerator Hub and will work in collaboration, according to the release, in The Ion, which is expected to open in 2021 with cohorts set to open applications in early 2021.

"We are really excited about working together with DivInc and the Rice Alliance for Technology and Entrepreneurship to realize the full potential of the opportunities that these funds will help unleash," says Jan Odegard, interim executive director of the Ion, in the release.

The Ion Smart and Resilient Cities Accelerator has cycled through two rounds of cohorts — first focusing on resilience and mobility in Cohort 1 then air quality, water purification, and other cleantech in Cohort 2.

The 12-week Clean Energy Accelerator was only recently announced by The Rice Alliance for Technology and Entrepreneurship at the annual Energy Tech Venture Forum earlier this month. The program is established to support Houston Mayor Sylvester Turner's Climate Action Plan.

Meanwhile, DivInc's accelerator comes out of a partnership with the Austin-based nonprofit and The Ion, which was announced in spring of this year. The goal with this program is to increase access to minority entrepreneurs.

"DivInc embodies the mindset that this generation and all the generations of innovators to follow must be inclusive of people of color and women entrepreneurs – who will build successful scalable growth companies to address tomorrow's challenges and opportunities," says Preston James, chief executive officer at DivInc, in the release.

"By removing the barriers that currently exist, we unleash this untapped potential and lift Houston to new economic heights. To do this we must establish strong collaboration with partners like The Ion, Rice University, the EDA and many others."

4 startups pitch at virtual demo day for Houston accelerator program

resillience

In light of COVID-19, it is more relevant than ever to discuss and support startups with sustainability and resiliency in mind. At The Ion Smart and Resilient Cities Cohort 2 Demo Day, a virtual audience was reminded of that.

"So, 2020 has certainly been a year of unprecedented uncertainty and change for Houston, for Texas, for our country, and for our world," says Christine Galib, director of the accelerator. "The past few months in particular have been especially difficult as the global pandemic and civil unrest continue to spotlight systemic and structural scars on the face of humanity."

The virtual event was streamed on July 1 and hosted several thought leaders and presenters before concluding with pitches from four of the cohort companies.

"Through it all, and in a virtual world, Cohort 2 startups, the mentors, and our Ion team have been the change we wish to see in the world," Galib continues. "For these startups, failure is simply not an option — and neither is going at it alone."

Earlier this year, Galib announced the second cohort would be focused on solutions for Houston's air quality, water purification, and other cleantech needs. The program, backed by Intel, Microsoft, and TX/RX, launched on Earth Day and commenced shortly after. Cohort 3 is expected later this year.

Here are the four companies that pitched and the problems they are trying to solve.

Re:3D

re:3D was founded just down the street from NASA's Johnson Space Center to address the need for a mid-market 3D printing solution. The Houston-based startup also wanted to create their 3D printer that operates on recycled plastics in order to prevent excess waste.

"Where some see trash, we see opportunity," Charlotte Craff, community liaison at Re:3D says in her presentation.

Re:3D's clients can get their hands on their own Gigabot for less than $10,000, and the printer uses pellets and flakes from recycled plastics —not filament — to print new designs. Clients are also supported by the company with design software and training.

"We can help the city of Houston help meet its climate action and resilient city goals by transforming the way people think about recycling," Craff says about Re:3D's future partnerships with the city.

Water Lens

While two-thirds of the world is covered in water, only 0.7 percent is drinkable. And of that fresh water, 92 percent of it is used in agricultural and industrial settings. This is how Keith Cole, CEO and founder of Water Lens, set the scene for his presentation.

Water Lens, which is based in Houston with a lab located in Austin, wants to solve the problem of cities and countries running out of fresh, drinkable water by equipping huge water-using companies with a water testing tool.

"We've developed a system to let anyone test any water literally anywhere in the world," Cole says, citing clients like ExxonMobil, Shell, and Halliburton.

S2G Energy

S2G Energy, based in Mexico, is focused on optimizing energy management in order to digitize, empower, and unlock potential for cost-saving efforts and technology.

In his pitch, Geronimo Martinez, founder of S2G Energy, points out that restaurants, commercial buildings, and other adjacent industries can save money by implementing energy management solutions that come out of S2G Energy's expertise. In Mexico, Martinez says, clients include the top two restaurant chains that — especially during COVID-19 — need optimization and cost saving now more than ever.

Eigen Control

A refinery's distillation columns are expensive — their fuel use accounts for 50 of operating costs, says Dean Guma, co-founder and CEO of Houston-based Eigen Control.

Guma explains in his pitch how Eigen Control's technology can plug into existing sensors, model networks based on data, and employ the startup's artificial intelligent technology to reduce carbon emissions and save money on operating costs.

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.
