Three Houston energy innovators have cut the ribbon on a new space for energy transition innovation.

The Energy Tech Nexus, located in the historic Niels Esperson Building at the corner of Travis and Rusk Avenue, opened on September 10, which was proclaimed Energy Tech Nexus Day by the city.

Jason Ethier and Juliana Garaizar, formerly in leadership roles at Greentown Labs, teamed up with Nada Ahmed, previously headed innovation and transformation at Aker Solutions, launched ETN as a community for energy transition startups. The new hub plans to host incubation programs, provide mentorship, and open doors to funding and strategic partnerships for its members.

"We are creating more than a space for innovation," Garaizar, who serves as CEO of ETN, says in a news release. "We are crafting a community where pioneers in technology and energy converge to challenge the status quo and accelerate the shift to sustainable energy solutions."

The hub describes its goal of tackling the "trilemma" of energy security, sustainability, and affordability while also contributing to the mission of setting up Houston as the global center for energy transition. To accomplish that mission, ETN will help facilitate rapid deployment of cutting-edge energy technologies.

'The future of energy is not just being written here in Houston; it's being rewritten in more sustainable, efficient, and innovative ways," adds Garaizar. "Houston provides the perfect backdrop for this transformation, offering a rich history in energy and a forward-looking approach to its challenges and opportunities."

"We believe that a broad spectrum of perspectives is crucial in solving global energy challenges. It's about bringing everyone to the table — startups, industry leaders, and investors from all backgrounds," she continues.

Ethier, who co-hosts the Energy Tech Startups Podcast with Ahmed, says he hopes that ETN acts as a meeting place for energy transition innovators.

"By providing the right tools, access, and expertise, we are enabling these companies to leap from ideation to implementation at an unprecedented pace;" Ethier explains. "The interaction between startups and established companies within Energy Tech Nexus creates a unique synergy, fostering innovations that might otherwise take years to mature in isolation."

Payal Patel, an angel investor who has held leadership roles at Station Houston, Plug and Play Ventures, and Softeq, also contributed to launching ETN, which is collaborating with George Liu, who has over 15 years of investment banking experience across energy, cleantech and hardtech with more than $20 billion in M&A projects across his career.

In May, ETN teamed up with Impact Hub Houston to establish the Equitable Energy Transition Alliance and Lab to accelerate startup pilots for underserved communities. The initiative announced that it's won the 2024 U.S. Small Business Administration Growth Accelerator Fund Competition, or GAFC, Stage One award.

ETN celebrated its opening during the inaugural Houston Energy and Climate Week.

Houston's innovation leaders weigh in on community's growth, progress

Houston innovation awards

This year's finalists in the Ecosystem Builder category for the Houston Innovation Awards have a lot to say about the city's innovation community — and they are the right ones to say it.

Selected as finalists for the newly created category, each of the five finalists are leaders for the Houston innovation ecosystem. They were each asked some questions about the development of the Houston tech and startup community. Here's what they had to say.

InnovationMap: What is your favorite part of Houston's innovation ecosystem? How have you helped contribute to that aspect of the community?

Jan E. Odegard, executive director of the Ion: Can do attitude and willingness to make big bets that can solve hard problems with global societal impact. Creating and supporting a place where this can happen is critical to the success, a place where we create the necessary density for collisions and that will sprue the next ideas.

Jason Ethier, co-founder of Lambda Catalyzer and host of the Energy Tech Startups podcast: Perhaps small, but the Ion District in the small part we have to play in it. Being able to be in a place where you can cross paths with active investors, innovators and partners. This is the hub we hoped to build over the last few years. That connective tissue may be small and focused compared to other ecosystems, but it is very strong here.

Joey Sanchez, founder of Cup of Joey and senior director of ecosystems at the Ion: My favorite part of the Houston Innovation Ecosystem is the progress and potential. We have gone from talking about how to build a Houston ecosystem to now exploring our collective potential. The conversations are now tactical actions to scale our efforts.

Kendrick Alridge, senior manager of community at Greentown Labs: My favorite part of the ecosystem is the Cup of Joey gathering. It's a great opportunity to run into or catch up with people looking to get involved in the ecosystem or looking for support. It's a great networking opportunity.

Wade Pinder, founder of Product Houston: I love seeing how the community has really connected this past year specifically. We've gathered momentum and have a "gravity well" of community leaders feeding value to one another.

IM: What are the strengths of the Houston innovation ecosystem?

Odegard: Access to (engineering) talent, capabilities, and global connectivity that are not afraid of getting her hands dirty to build and scale.

Ethier: The diversity of the founders and the intrinsic diversity of the Houston ecosystem. There are few native Houstonians, and most of the fantastic founders we meet are from somewhere else. The energy industry brings the best of the best from around the world and they inject Houston with unique excellence.

Sanchez: We are a resource right environment. We have a plethora of talent and capital. With the economy the size of Belgium, we have access to industries and talent unlike any other city. Also the convergence of energy, medical and aerospace is one of a kind. Each industry is transforming and providing a ripe opportunity for innovation.

Alridge: The growing number of startup development organizations (SDOs), incubators and accelerators, makerspaces, co-working spaces, non-profits, and academic institutions that is available is a strength, because their are plenty of places to get support and your ideas off the ground.

Pinder: We do hard things here because the ARE hard! 1) Life and death situations en masse, 2) infrastructure at scale 3) Boldly going where no one has gone before! That's what we've done here. That's what we stand to innovate on! If it's a hard problem, Houston gets it done!

IM: What are the weaknesses of the Houston innovation ecosystem? Are you helping to make improvements to these weaker aspects of the community and, if so, how?

Odegard: Access to more risk capital.

Ethier: We need a skill set on scaling businesses. This is something the valley does exceptionally well. When there is product market fit, the startup ecosystem knows how to scale teams from 20-200 and do so repeatedly. Houston knows how to do big energy projects; from sput to TD, there is a skill set here around complexity...but how that applies to scaling businesses its unclear we have what it takes. This is why its imperative we bring in mature startups from around the country and try to transfer knowledge from the energy industry into the startup space. Building an acceleration program like Lambda is a step in solving this problem.

Sanchez: Density is our biggest challenge. The geographic sprawl of our region is vast. Serendipitous meetings are a challenging. The Ion has created a central place where our ecosystem can come together. Every Friday we meet for Cup of Joey and now we host a Cup of Joey in The Woodlands, Space Center Houston, Sugar Land and The Cannon West. Creating eight Cup of Joey meetups each month. The most exciting element of Cup of Joey is coming in an online platform for connection.

Alridge: We need a robust cadre of startup specialists, serial entrepreneurs who have successfully started companies. Especially in business and STEM fields, is needed in the innovation system. Higher education in providing talent is important, I'm doing my part by organizing opportunities for students to work with our startups which can directly and indirectly contribute to the workforce and the grown startup community.

Pinder: We're changing this... but we still have a ways to go with the "I'm good... what do I need to show up for?" thinking. It's not for lack of wanting to show up... traffic makes it tougher to show up most of the time.

IM: What do you wish more people knew about the Houston startup community?

Odegard: That Houston IS a tech hub addressing some of the biggest societal challenges we are face today, such as: power (security), healthcare (affordable and accessible), sustainability (clean and green), and equitable access to economic opportunities.

Ethier: How climate focused everyone is, from the founders, to the SMEs, industry and SMEs. Houston (and energy companies) know how to manage what's measured and now that we have targets around decarbonization, we are going to get it done.

Sanchez: I wish the world knew more about Houston and our Houston startup community. I believe that our foundation is strong and we are ready for scale. 2026 to 2036 will be a decade of massive growth for Houston and our ecosystem.

Alridge: We are more than oil and gas and health care.

Pinder: We've got the solutions to some huge problems sitting right here in Houston.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from clean energy to materials science — recently making headlines in Houston innovation.

Jason Ethier, senior director of membership at Greentown Labs

Jason Ethier witnessed Greentown Labs, a climatetech incubator based in Somerville, Massachusetts, outside of Boston, from its early days.

"Greentown is one of those things where a business seems obvious in retrospect," says Ethier, a serial energy entrepreneur, on this week's episode of the Houston Innovators Podcast, explaining how the incubator launched as just a way to enable coworking between startups. As it grew and eventually expanded to Houston, Ethier had a front-row seat.

Ethier, whose previous startup brought him to Houston frequently, recognized the same scrappy founder mentality and need for incubation support in the Bayou City and was a key player in expanding Greentown to Houston in 2021.

"Every city is proud of who they are, but I think Houston especially is a city that likes to solve problems and build things locally," Ethier says. "When presented the opportunity to help build and ecosystem here, members of the ecosystem raised their hands and said, 'how can I help.'" Read more.

Megan Eddings, founder of Accel Lifestyle

For a year, Megan Eddings, founder of Accel Lifestyle, has been working on the logistics of getting her clothing — made from eco-friendly, sustainable, antibacterial fabrics — into Talbots, and she's finally sealed the deal.

Shoppers can now find Accel Lifestyle apparel on Talbot's website. This partnership marks the first-ever collaboration for the athleisure brand of Talbots, T by Talbots. By teaming up with Accel Lifestyle, Talbots expands its product offerings and also provides its loyal, forward-thinking, and ethically minded customers with a new clothing option that perfectly fits with their values.

"We are beyond elated about the Accel x Talbots launch," Eddings tells CultureMap." Amanda Cotler, Accel's Director of Operations, and I have been working on this opportunity for a year, and it feels incredible for the collaboration to be live. Our passions are textiles with technology and an ethical made-in-the-USA supply chain. To have a multi-billion dollar company like Talbots care about the same things brings us so much joy."

Houston-founded Cart.com, which provides a suite of software solutions for commerce and logistics enablement, can now check the box saying "unicorn" with its $1.2 billion valuation that came with its $60 million series C equity funding round.

According to a news announcement from the company, Cart.com will use the funding for international expansion, continued product development, and to meet increased client demand.

“We are proud to partner with this prestigious group of investors to accelerate our growth and continue to deliver best-in-class solutions to our customers,” says Omair Tariq, CEO and co-founder of Cart.com, in a statement. “As a leading commerce software and services provider, we are focused on enabling our customers to compete and win across every channel through digital tools and digitally driven logistics capabilities. We will continue to invest in our industry-leading commerce data capabilities, which are built to address the specific inventory, channel and supply chain challenges facing enterprises.” Read more.

Why this innovator is dedicated to supporting, showcasing Houston energy tech startups

HOUSTON INNOVATORS PODCAST EPISODE 192

Like many successful operations, Greentown Labs, a climatetech incubator based in Somerville, Massachusetts, outside of Boston, had its humble beginnings.

"Greentown is one of those things where a business seems obvious in retrospect," says Jason Ethier, a serial energy entrepreneur, on this week's episode of the Houston Innovators Podcast.

He says he and a few other founders were working on their various ventures in a building that ended up getting slated for demolition, forcing them to find a new place to set up shop.

"We were all building stuff within energy and technology," Ethier remembers. "We had to find a new building, and the landlord looked at us and said, 'I don't want to deal with a bunch of small companies. I want one company, one check, and one lease."

The group of entrepreneurs formed Greentown as a way to make the rent work, but they started attracting interest from other founders who wanted in. The organization evolved to what it is today — a dual-located energy incubator that's supported over 500 companies that have raised over $4 billion in funding.

Ethier, whose startup at the time brought him to Houston frequently, recognized the same scrappy founder mentality and need for incubation support in the Bayou City and was a key player in expanding Greentown to Houston in 2021.

"Every city is proud of who they are, but I think Houston especially is a city that likes to solve problems and build things locally," Ethier says. "When presented the opportunity to help build and ecosystem here, members of the ecosystem raised their hands and said, 'how can I help.'"

Juliana Garaizar, who was hired as launch director for Houston and now is head of Greentown Houston, tapped Ethier to support the expansion into town. Now, as senior director of membership at Greentown Labs, he works hands on with startups at Greentown.

He's taken his knowledge as a serial entrepreneur and incubation leader to launch the EnergyTech Startups podcast with co-host Lara Cottingham, the vice president of strategy, policy, and climate impact at Greentown Labs.

"As an entrepreneur, sometimes you feel a gap in the market in your bones and you just have to do something about it," Ethier says, explaining that he observed that when meeting people, he realized Houston got a bad rap. "Houston isn't viewed as a cool place to build a company if you don't know how good it is to be here."

The other thing Ethier says he realized was that Houston founders were understated in what they accomplished. So, he set out to start a podcast that would shine the spotlight on a Houston energy entrepreneur on a regular basis. The show, launched last fall, das now introduced listeners to over 20 energy founders and is continuing to do so on a biweekly basis.

Ethier shares more on his views of the future of Houston as an energy transition leader on the show. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

2 Houston startups win big at SXSW 2025 pitch competition

winner, winner

Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs echoed that sentiment with a post on LinkedIn celebrating the win.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” the post read. "Today, that mission feels even stronger."

The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

Two other Houston companies were selected as finalists:

  • Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
  • Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.

A legacy of industrial technology excellence: UTSI International turns 40

Cheers to 40 Years

As UTSI International celebrates its 40th anniversary, president and CEO Shaun Six reflects on the company's history, achievements, and exciting future.

---

In March 1985, Dan Nagala and a few friends took a risk, leaving their full-time jobs to pursue their passion and start their own company.

They founded UTSI Internationalamidst groundbreaking advancements in Industrial Control Systems and SCADA technology, revolutionizing remote operations for critical infrastructure. From the start, UTSI has been at the forefront of OT innovation and integration — a legacy we proudly carry forward today.

The legacy of Dan Nagala

Dan Nagala’s 50-plus-year career is too vast to cover every accomplishment, but if you’ve ever heard the phrase “Houston, we have a problem” in a movie, those screens in the control room and the logic causing the “blinky lights” to alert the operators, you’ve seen some of his work. Dan and his team ultimately paved the way for field communications to detect and communicate leaks on pipelines and give operators in remote locations situational awareness, expanding their ability to safely monitor and control their operations.

This capability was requested early on in the first pipeline control rooms, leading to UTSI’s first check-in 1985 (which I proudly have framed on my bookshelf). The protocols to communicate and do advanced calculations — which many would be tempted to call AI today — for the purpose of monitoring and control, was created from this group of enthusiasts who open sourced it and allowed it to proliferate, leading to over 80 percent of all critical infrastructure in the world now utilizing a variant thereof.

Given the novelty of the technology and the experience of UTSI, having implemented control systems and automation for pipelines in over 22 countries, Dan was asked to collaborate with industry experts, creating the first API leak detection and control room management standards for the American Petroleum Institute. These would later become regulation under PHMSA, DoT, and TSA, placing UTSI as the go-to experts in compliance in addition to their traditional expertise.

UTSI has delivered for the world’s largest infrastructure owners in multiple critical infrastructure sectors, like mining, water/wastewater, oil and gas, green energy, transportation authorities, etc. We have also done AI and cybersecurity, in addition to SCADA and ICS work for the DoD and DoE.

Strength in partners

I joined UTSI in 2022 as vice president, working under Dan, with the goal of gradually stepping into leadership. In 2023, I became CEO, president, and majority shareholder. While no one can truly fill Dan’s shoes alone, we’ve focused on strengthening our team, partnerships, and capabilities to continue UTSI’s legacy of excellence.

One of our first strategic partnerships was with Tory Tech, a leading API-compliant Control Room Management tool. UTSI has worked as integrators with Tory Tech for years and Dan worked as a CRM compliance advisor for them in the U.S. while they were setting up their headquarters in Houston. In 2024 we made it an official partnership, becoming a preferred integrator and focusing our team on training and development in the MaCRoM (Master Control Room Management) tool.

We've also made significant investments in our OT cybersecurity capabilities, expanding our team and partnering with industry leaders like Dennis Parker, Derrik Oates, Nozomi Networks, Fortinet, and Schneider Electric. These strategic moves ensure we deliver top-tier expertise, products, and solutions to better serve our customers.

Our partnership with ThreatGEN and the utilization of their AI-driven “AutoTableTop” tool not only utilizes our experience with TSA guidelines, but adds an element of reality that the traditional methods are lacking, making these engagements more interactive and beneficial for operators who are required to participate annually.

In 2024, UTSI also invested heavily in AI and Data Science by acquiring Houston-based AI company Pandata Tech and leveraging their Data-Quality-Methodology (DQM), Leak Geek, and time-series data science expertise to solve industry specific problems.

Moving up – in and around Houston

Building on our recent successes, we strategically relocated our office to the Netrality building (1301 Fannin St.), bringing us closer to clients and partners, while getting access to a Tier 3 Data Center with an uninterrupted 40-year power record.

Netrality is a SOC2-compliant facility with seven points of detection from the street to our server, including biometric screening. Our very own Roberto deLeon has architected our upgraded servers using the Purdue model as a basis of design while leveraging our relationship with Fortinet to standardize our hardware and software to the highest standards. We practice what we preach — every architecture, framework, and hardware recommendation we make is not just advised but actively implemented within our own operations.

Our investment in this space includes increasing our “SCADA R&D Lab” to play with toys from vendors, testing them out in our environment before we recommend and advise them to our clients and partners. Currently we’re working on LLMs for OT, building our own “DANN2.0” for use in-house. DANN is an homage to Dan Nagala (and, for the nerds, stands for Dan Artificial Neural Network), which we started in 2022 when I realized that knowledge capture is an industry wide epidemic and we need to be ready to integrate for our clients in a safe and local way at scale, in the OT environment.

Additionally, having come from a startup before joining UTSI, I wanted to get us closer to the heart of innovation, so we’ve added additional office space at The Cannon downtown. While there are many tech hubs around Houston, and we are proud to work with and partner with companies from Greentown Labs and the Ion, to name a few, we’ve found that The Cannon community is incredibly active and innovative, with experience in industrial use-cases.

Houston is set to become the Energy Transition capital, leading in hydrogen, carbon capture, and repurposing. With a 5:1 ratio of engineers leaving the industry and an average age over 60, we must innovate. The solution lies in combining a secure, cloud-free "ChatGPT for OT" with digital twins. Bringing the field to engineers is essential. We've partnered with a satellite constellation for asset imaging and U.K.-based Mods Solutions to leverage their CFIHOS-driven platform for intelligent digital twins — more on that partnership soon!

And we will need to leverage enhanced automation tools and actively monitor control networks to ensure security and respond quickly to issues, which is why we’ve partnered with Nozomi Networks.

Shaping the future

Although Dan has semi-retired to his cabin in Montana, he continues to do “the fun stuff” that brings him joy, such as conducting research for PRCI and assisting long-time clients. He also has been a mentor and advisor to me since I started at UTSI three years ago. I’m grateful for him and the group of industry experts he gathered around him to make UTSI such a well-known systems integrator and OT advisor for the world’s largest asset owners.

Our group of experts are active in the industry and will be speaking at events throughout the year, with a presence at Entellec, Level Zero, and participating at this year's API Cybernetics and PSIGs biannual conferences. We proudly serve on the BCarbon advisory board and GHPs Energy Committee.

Lastly, we have one request: We see a critical need for H2 and supercritical CO2 studies to develop simulation models, response plans, and leak detection best practices. These gases differ from those covered in existing standards. If you know anyone interested in funding or contributing, we’re collaborating with industry partners to secure support.
