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.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
