A clean energy program has announced its third cohort and named the 15 startups that were accepted into to the accelerator.

The Rice Alliance's Clean Energy Accelerator revealed its 2023 cohort that will be in the 10-week program that kicks of July 25. CEA, a hybrid program based out of the Ion, will wrap up with a Demo Day alongside the 20th Annual Rice Alliance Energy Tech Venture Forum on September 21.

The accelerator, led by Kerri Smith and Matt Peña, provides the cohort with programming, networking, and mentorship from six executives in residence — Nathan Ball, Fatimah Bello, Michael Egan, Michael Evans, Stephen Sims, and Deanna Zhang.

Since the Clean Energy Accelerator launched in 2021, the program has supported 29 ventures that have gone on to raise over $75 million in funding, identified and launched pilots, and created jobs, According to Rice, many of these companies relocated to Houston.

Class 3, which has already raised $23.3 million in funding, hails from four countries and seven states and are addressing a range of energy solutions — from advanced materials, carbon management/capture, energy storage, hydrogen, solar energy, wind energy, and more. They were selected by a screening committee consisting of more than 50 industry experts, investors, energy leaders, and entrepreneurs.

The third class, as announced by Rice Alliance, is as follows:

  • Ayrton Energy, based in Alberta, Canada, provides hydrogen storage technology that improves hydrogen transport logistics for distributed energy applications.
  • Headquartered in Massachusetts, Carbix transforms atmospheric carbon dioxide emissions into building materials using proprietary reactor technology.
  • Houston-based CryoDesalination lowers the carbon footprint and cost of removing salts and heavy metals from water and industrial effluents.
  • Digital Carbon Bank, based in Alberta, Canada, provides a carbon solution tailored for the energy industry.
  • Chandler, Arizona-based EarthEn provides compressed carbon dioxide-based energy storage and artificial intelligence solutions allowing grid owners/operators to be completely renewable.
  • H Quest Vanguard, from Pittsburgh, provides green hydrogen at a five to 10 times lower cost to users of natural gas to decarbonize industrial heat.
  • Calgary, Alberta-based Highwood Emissions Management's SaaS platform allows oil and gas companies to understand their emissions and develop robust plans to reduce them.
  • Icarus RT, from San Diego, California, improves photovoltaic efficiency while enabling useful heat energy storage.
  • Los Altos, California-based Khepra has developed a chemical manufacturing platform for the low-cost, sustainable production of agrochemicals.
  • Binghamton, New York-based Natrion’s electrolyte is a drop-in solid-state battery component that can be rapidly implemented into existing batteries.
  • Oceanways, based in London, provides low-cost, flexible and scalable zero-emission underwater "virtual pipelines" to energy producers.
  • Relyion Energy, from Santa Clara, California, is developing battery usage and intelligence solutions with deeper data and insights for retired electric vehicle batteries.
  • Massachusetts-based Triton Anchor provides a more cost-effective anchoring solution for offshore clean energy with minimal environmental impact.
  • TROES, from Markham, Ontario, provides a 4-in-1 microgrid solution with integrated hardware and software for a streamlined energy storage experience.
  • Mexico City-based Tycho Solutions supports clean energy project developers by saving time and money during the critical project-siting process.

Houston experts shine spotlight on impact investing following angel network expansion

calling for impact

Houston innovators called for existing and potential investors to focus on impact investing — for the improvement of both society and your bottom line.

SWAN Impact Network, which announced its expansion into Houston earlier last month, is an investment organization that prioritizes funding mission driven startups and educating angels on how to analyze impact investment companies. The organization hosted a launch event and panel at the Ion last week to discuss the process and goals of impact investing and highlighted their own success stories as angel investors. The panelists included Bob Bridge, Kerri Smith, and Emily Reiser, who were moderated by Grace Rodriguez, executive director of Impact Hub Houston.

Emily Reiser, associate director of the Texas Medical Center’s innovation team, said impact investing, though focused on improving people’s lives through innovations, should still rely on typical business models and return profiles.

“It’s not charity investment, it’s investing with an eye towards how that investment is going to also return to the greater society as well as back to your pockets,” Reiser says.

As there was a mix of prospective angel investors and entrepreneurs in attendance at the event, Reiser encouraged the founders to have formal business plans in place before meeting with investors, from setting up customer feedback systems to budgeting estimates.

“In the impact space you’ll get some great enthusiasm from people who want to join your mission to save lives, or change the world, or save the planet but make sure you do all the rest of the work behind that to build out the rest of your business model, figure out how you’re going to sell, get it optioned, and on the market,” Reiser says.

Bob Bridge, the founder and executive director of SWAN, stressed the importance of examining long term consequences of impact-driven startups. Bridge illustrated the importance of doing research into how these startups could unintentionally harm communities before investing in them by discussing the well known shoe manufacturer TOMS, whose business model revolved around matching each pair of purchased shoes by donating a pair to people in developing countries, putting local manufacturers out of business.

“These companies are often just now entering the market place so they can’t measure their actual impact results yet because they’re not delivering services or products yet,” Bridge says. “We look for them to have some sort of data to give us a clue if what they’re doing is going to work … convince us there is efficacy to what you are doing and that your impact solution is competitive.”

Bridge also adds there is no concrete definition of impact investing because every society has different needs to be met through creative solutions, from developing more robust technology to encouraging the hiring of underrepresented minority groups. When making decisions over which companies to invest in, Bridge says he also prioritizes startup teams that are collaborative and transparent.

“We don’t invest in Steve Jobs' kind of personalities … We want people who are always learning from their customers, competitors, and employees,” he explains.

Kerri Smith, executive director of the Rice Alliance Clean Energy Accelerator program, says her team readies their emerging startups to tackle meetings with investors by asking them to quantify the impact of their technology on users.

“We’re seeing a lot of investors as well as boards of directors requiring companies to be more responsive to those kinds of things,” Smith says. “We try to prepare the startups in ways that will make them more ready to answer questions about the impact that they’re having societally as well as financially.”

Houston university granted $1.2M to expand STEM-focused initiative

science support

Rice University is receiving a five-year $1.2 million grant from the National Science Foundation to expand a program that helps faculty members, researchers, and doctoral students commercialize STEM-oriented technology.

Rice is one of the founding partners of the science foundation’s Southwest I-Corps Node. Rice and the two other founding partners are sharing a $15 million grant to help add five universities to the program.

Rice, Texas A&M University, and the University of Texas established the Southwest node in 2014. The five schools forming a new hub within the node are the University of Texas at San Antonio, the University of Texas at El Paso, Oklahoma State University, New Mexico State University, and Louisiana State University.

The foundation’s I-Corp program not only boosts STEM-related technologies developed at universities, but it also provides $50,000 grants for STEM-based faculty members and doctoral students to participate in a six-week training program to help researchers bring technologies from the lab to the marketplace. Over 1,000 startups have been formed after completing the I-Corps program; they have raised more than $750 million in funding.

Kerri Smith, associate managing director of the Rice Alliance, leads the university’s I-Corps program, along with Kaz Karwowski, executive director of the Rice Center for Engineering Leadership, and Jessica Fleenor, a Rice Alliance I-Corps teaching assistant and I-Corps program manager.

“Thanks to the Rice Alliance’s more than two decades of leadership, Rice has built an entrepreneurial culture on campus, served as a founding member of the I-Corps program, and provided entrepreneurial education to hundreds of faculty and students,” says Reginald DesRoches, president of Rice.

Rice has received more than $3.1 million in National Science Foundation grants for the I-Corps program, plus about $1.3 million as part of the I-Corps node. Rice faculty members and researchers have received more than $600,000 in I-Corps grants.

Previous I-Corps participants at Rice include:

  • Volumetric Biotechnologies, a startup founded by Jordan Miller, an assistant professor of bioengineering assistant professor, and based on Miller’s 3D organ-printing technology. Volumetric was acquired last year by 3D Systems for up to $400 million.
  • SPLAY (formerly Arovia), which completed the I-Corps program in 2015. Through two Kickstarter campaigns, the company has successfully raised money for its high-definition, portable, large-scale computer display technology.

As the managing director for the Rice Alliance for Entrepreneurship and Technology's Clean Energy Accelerator, Kerri Smith is focused not only on the program's cohorts but on supporting the Houston cleantech ecosystem as a whole. CEA works with Greentown Houston, which is just next door to the program's home at The Ion, and the Greater Houston Partnership's Houston Energy Transition Initiative.

"Rice Alliance has a strong history of demonstrating collaboration with a number of organizations," Smith says. "I think one of the primary benefits that we have in these collaborative opportunities is to ensure that we are collectively building a capable and diverse pipeline of talent to solve for these problems and provide them with access to experiencing all of the benefits of our ecosystem."

Smith shares more about what she's looking for in the second cohort of CEA on a recent Houston Innovators Podcast episode, as well as what she sees as Houston's role in the energy transition. Click here to read more and stream the episode.

A national startup accelerator has announced its fifth local cohort, which includes five Houston companies participating in the spring 2022 class, and the new leader that will oversee the program. Muriel Foster is the newly named director of gBETA Houston, which is designed to help guide early-stage startups find early customer traction, connect with mentors, and more.

“The five companies selected for the Spring 2022 cohort tackle unique problems that have propelled them to create a business that solves the issues they once faced," Foster says in a news release. "From public speaking, apparel comfort, and food delivery from underrepresented restaurant owners, these founders have found their niche and are ready to continue to make an enormous impact on the Houston ecosystem."

A Houston native, she has her master’s in public administration from Texas Southern University and a bachelor’s in marketing from Oklahoma State University. Her background includes work in the nonprofit sector and international business consulting in Cape Town, South Africa, and she's worked within programming at organizations such as MassChallenge, BLCK VC, and now gener8tor.

Cleantech accelerator leader looks forward to new cohort and making an impact on Houston's energy transition

HOUSTON INNOVATORS PODCAST EPISODE 134

Kerri Smith knows accelerators. Through her over 18 years at Rice Alliance, she's been responsible for overseeing several and was on the founding leadership team of Houston's first energy tech startup accelerator, SURGE. After years of focusing you accelerating Rice University's student-focused program, Owl Spark, she's transitioned back into the energy tech space.

"I've worked with many types of founders. There's not one unique characteristic that everyone has," Smith says on the Houston Innovators Podcast. "Our goal is to help move them along and help them move the needle. At the end of the day, we want them to have a good experience and to meet their goals and objectives."

The Rice Alliance's Clean Energy Accelerator launched last summer with its inaugural cohort of 12 cleantech startups, which represented energy sectors from solar and wind innovations to hydrogen, geothermal, and more. Smith says the startups represented a wide range of stages and were from all over — only two companies were from Houston originally. The out-of-town companies were able to make critical partnerships in town and set up a presence and a home here.

"We were able to build a family-like culture among our group, and that was something that was wildly appreciative," Smith, who serves as executive director of the program, says.

Applications for Class 2 of CEA are open until May 31. While the program will offer the same access to mentorship and opportunities, the program will change slightly. CEA will focus on seed and series A-stage companies and will be a hybrid program. Throughout the 10 weeks, which begins in the fall instead of the summer this year, founders will visit Houston three times at the beginning, middle, and the end of the accelerator. Each startup will receive a grant to cover the expenses of the equity-free program.

CEA is just one part of a greater ecosystem of innovation under the umbrella of Rice University, which includes the Rice Alliance for Technology and Entrepreneurship, the Liu Idea Lab for Innovation and Entrepreneurship, The Ion Houston, Owl Spark, and more. All these entities also play into the greater Houston area's innovation ecosystem.

"Rice Alliance has a strong history of demonstrating collaboration with a number of organizations," Smith says. "I think one of the primary benefits that we have in these collaborative opportunities is to ensure that we are collectively building a capable and diverse pipeline of talent to solve for these problems and provide them with access to experiencing all of the benefits of our ecosystem."

With CEA specifically, some of these collaborations include working with Greentown Houston, which is just next door to the program's home at The Ion, and the Greater Houston Partnership's Houston Energy Transition Initiative.

"We're a cog in the wheel. We do really well with that. We play well with others – in ways that the founder has a good experience and can benefit," Smith says.

Smith shares more about what she's looking for in the second cohort of CEA on the podcast episode, as well as what she sees as Houston's role in the energy transition. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

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 two local innovators, as well as one honorary Houstonian, across industries — energy, manufacturing, and more — recently making headlines in Houston innovation.

Juliana Garaizar has a new role within Greentown Labs. She's lead the local team as launch director, and now is taking a new role now that Greentown Houston has opened its doors. Garaizar recently discussed with InnovationMap why now is the perfect time for Greentown to premiere in Houston.

"I think that if Greentown had happened one year before or even one year later, it wouldn't be the right time. I really believe that our main partners are transitioning themselves — Shell, Chevron, and many others are announcing how they are transitioning," she says. "And now they look at Greentown as an execution partner more than anything. Before, it was a nice initiative for them to get involved in. Now, they are really thinking about us much more strategically." Click here to read more.

Electronics manufacturer and MacroFab, run by CEO Misha Govshteyn, much like the rest of the business world, was not immune to the effects of the pandemic. But as some business returned last summer, Govshteyn says MacroFab bounced back in a big way.

"In a lot of ways, the concepts we've been talking about actually crystalized during the pandemic. For a lot of people, it was theoretically that supply chain resiliency is important," Govshteyn says on this week's episode of the Houston Innovators Podcast. "Single sourcing from a country halfway around the world might not be the best solution. ... When you have all your eggs in one basket, sooner or later you're going to have a break in your supply chain. And we've seen nothing but breaks in supply chains for the last five years."

New Texas Stock Exchange officially begins trading in Dallas

Welcome to Y'all Street

Two-step aside, New York Stock Exchange and Nasdaq. The Dallas-based Texas Stock Exchange, nicknamed Y’all Street, just kicked off live trading with five stocks — and lots of Lone Star ambition.

“The Texas Stock Exchange aims to revitalize competition for [stock] issuers, establish the premier venue for listings, and create a world-class trading platform for all market participants,” the exchange says in a fact sheet.

The exchange — whose Texas-influenced nickname is a nod to New York City’s Wall Street — has collected at least $275 million in investments. The roughly 90 financial backers of TXSE include Bank of America, BlackRock, Charles Schwab, Citadel Securities, Dell Family Office, Fortress, Goldman Sachs, and JPMorgan Chase.

Representatives of TXSE couldn’t be reached for comment. On its website, the exchange calls itself “the most well-capitalized equities exchange to ever be approved” by the U.S. Securities and Exchange Commission (SEC).

Not to be outdone, NYSE has launched Dallas-based NYSE Texas and Nasdaq has expanded its presence in Dallas.

Y’all Street adds to Dallas-Fort Worth’s rising status as a major hub for financial services, with The Wall Street Journal naming North Texas the country’s second biggest financial hub after New York City.

“A homegrown national exchange means more jobs, more investment, and more growth opportunities for businesses and communities across the Lone Star State,” Gabriela von zur Muehlen, senior vice president and chief policy officer at the Texas Association of Business, told The Texas Tribune.

Bulent Temel, an associate professor of practice in economics at the University of Texas at San Antonio, told Texas Standard that TXSE “is going to boost the credibility of the Texas economy.”

Texas’ estimated gross domestic product (GDP), a yardstick for the size of an economy, climbed to a record-setting $2.9 trillion in 2025, making it the state with the second highest GDP after California. DFW’s estimated GDP in 2023 stood at $744.6 billion, eclipsing the GDP of many countries.

“The center of gravity for American capitalism is now headquartered in the Boom Belt,” Abbott proclaimed in April, referring to an 11-state region (including Texas) in the South and Southeast that’s seeing tremendous economic and population growth. “The Texas Stock Exchange is the natural extension of that capitalism. It ensures that capital markets will reflect the quadrant that is driving American growth.”

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.

Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.
