Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite. Greentown Houston has supported 175 startups since its launch in 2021, with 45 joining in the last two years. Those startups include the likes of Hertha Metals, RepAir Carbon, Solidec, Eclipse Energy (formerly GoldH2) and many others.

Healthtech Accelerator (TMCi)

The Healthtech Accelerator, formerly TMCx, focuses on clinical partnerships to improve healthcare delivery and outcomes. Emerging digital health and medical device startups that join the accelerator are connected with a network of TMC hospitals and seasoned advisors that will prepare them for clinical validation, funding and deployment.

The Healthtech Accelerator is part of Texas Medical Center Innovation, which also offers the TMCi Accelerator for Cancer Therapeutics. The Healthtech Accelerator named its 19th, and latest, cohort of 11 companies last month.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with 24,000-plus members spanning 69 countries, making it one of the world’s largest communities for accelerating entrepreneurial solutions toward the United Nations' Sustainable Development Goals (SDGs).

Houston coworking concept expands with new location

coming soon

The Cannon has announced its latest coworking location, and it's not too far from where the company's original facility launched.

The Cannon Memorial is expected to open this spring in Two Memorial City Plaza (820 Gessner) within MetroNational's Memorial City, a 265-acre planned development in west Houston. The coworking concept will take up one floor with 21,960 square feet of space.

"We are delighted to unveil The Cannon Memorial as a pivotal addition to Houston's dynamic business landscape," Jon Lambert, CEO of The Cannon, says in a news release. "Our expansion into Two Memorial City Plaza aligns seamlessly with our mission to cultivate innovation, collaboration, and success within the business community. We eagerly anticipate welcoming entrepreneurs and professionals to experience the unparalleled environment we've created."

The new location is less than three miles from The Cannon West Houston (1334 Brittmoore Rd) and will feature:

38 private office spaces
accomodations for over 60 flex users
24/7 access for members
free covered parking in the attached garage

Sports tech festival coming to Houston this spring names 2 inaugural partners

game on

A sports-focused festival planning to premiere this spring has named two brand partnerships today.

Pokatok announced its teaming up with Beasley Esports and World Freestyle Football Association for the festival set to take place in downtown Houston on April 4 to 7, 2024.

“We’re building the world’s fair for sports which means showcasing as wide a variety of different sports as we can,” Lawson Gow, Pokatok co-founder, says in the news release, “and these two partners could not be more illustrative of the mix we are trying to achieve.”

Beasley Esports, which owns the Houston Outlaws, Team AXLE, and Juggernaut, will drive esports and gaming at the festival, as well as assist on programming, competitions, and more. The organization will also help coordinate activities — such as meet and greets and competitions — with esport professionals.

“I am most excited to see traditional sports and esports share the big stage — redefining the evolution in sports and technology and spotlighting all the excitement that lies ahead for sports enthusiasts — as it’s never been done before,” Lori Burgess, COO of Beasley ESport, says in the release.

The other newly announced partner, WFFA, will feature programming of its unique sport, freestyle football, which is defined in the release as a fusion of acrobatics, dance, music, and tricks with a football.

“The vibe and energy of what the Pokatok Festival will be, is perfectly in sync with the sport of Freestyle Football and what we do,” Dan Wood, co-founder of the WFFA, says in the release. “With the FIFA World Cup coming to Houston in 2026, it’s a great opportunity for everybody to already experience some other forms of Football related sporting entertainment.”

Pokatok was officially announced earlier this summer by its parent company Gow Companies, founded by Lawson Gow (who is the son of David Gow, InnovationMap's parent company's CEO). The festival will feature a sports tech expo, a film festival, speakers and panels, live music, pitch competitions, and more. The venue will be George R. Brown Convention Center, Discovery Green, and various nearby hotels. The full lineup of events has not yet been released, but interested parties can opt in for pre-sale information online.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.
