A new Houston company has launched to provide a new platform of resources for entrepreneurs powered by artificial intelligence, and the new business already has its first partner.

The Cannon, a coworking community with locations across Houston, and nstAI, a newly launched suite of services for founders, announced a new partnership.

“The opportunity for The Cannon to partner with nstAI to bring a value-driven service offering to growth stage startup organizations is huge for our community. We are constantly looking for areas where we can support every startup, no matter where they are in their journey,” Jon Lambert, The Cannon’s CEO, says in a statement. “The nstAI offering, delivered through The Cannon's platform, will bring tremendous value to emerging companies who are in perhaps the most critical stage of their journey, garnering true market presence and customer share.”

Founded by seasoned entrepreneurs, nstAI's support is targeted aid startup founders during the early phases of business development, including securing non-dilutive funding, creating pitch decks and other materials, as well as making meaningful connections with mentors and potential customers.

"The journey from post-Seed funding to Series B funding is often one of the most challenging phases for founders," John Cooper, a founding partner at nstAI, adds. "We've designed nstAI to be a trusted resource in that process, offering hands-on guidance, leveraging AI-powered tools, and providing access to an unmatched global network of experts and investors."

The nstAI platform will be integrated into The Cannon's digital platform, Cannon Connect, for its members.

"nstAI is more than just a service provider; we're a community of successful entrepreneurs dedicated to supporting each other's growth and success," Mark Voytek, founding partner at nstAI, says in the release.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a podcast with the CEO of a community-focused coworking space, a professor joining a major health care research project, and a guest columnist with advice on navigating the energy transition.

For the past five years as CEO, Jon Lambert has faced some challenges leading The Cannon — from navigating a global pandemic to the subsequent evolved real estate market. But now, the coworking and community building company is poised for even more growth — especially with its ninth location opening up this month — thanks to its community-driven mission.

The Cannon Memorial opens its doors on Monday, May 13, with a week of free coworking and events. And while the new space, developed in partnership with MetroNational, is open for leasing, Lambert says on the Houston Innovators Podcast the first and foremost, The Cannon is a community.

"The Cannon wasn't created as a real estate play — we got into coworking because as we started supporting the community and asking the question of, 'what can we do for you?,' one of the highlights was, 'hey, we need space to work,'" he says on the show. "For us, we were going to provide space because that's one of the key needs of this community.

"Our measurement of success is not the buildings we have or the occupancy even — it's what's the success of the companies that are part of the community," he continues. Click here to read more.

As senior vice president of Enchanted Rock, a Houston-based provider of microgrid technology, Ken Cowan has seen how energy resilience has emerged as a key strategy for businesses across industries, as he writes in a guest column for InnovationMap.

"Executives must recognize the strategic imperative of investing in resilient energy infrastructure like microgrid systems, which can provide a competitive advantage against organizations that do not have similar measures in place," he writes. "In doing so, they can navigate uncertainty with confidence, set their business up for future success, and emerge stronger and more resilient than ever before."

In the piece, he explores the value proposition and other benefits to making these changes. Click here to read more.

An engineering project at the University of Houston has been selected to join a $10 million effort to bring biopharmaceutical manufacturing into the future. The National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL) chose the lab of Richard Willson, Huffington-Woestemeyer Professor of chemical and biomolecular engineering at UH, as one of eight development projects that it will fund.

Willson and his team are working to develop a mix-and-read antibody measurement system that uses fluorescent materials to determine the amount of antibody present in a sample. The funding for this project is $200,000. This is the first grant UH has received from NIIMBL.

“In the course of the manufacturing processes, it's important to know the concentration of antibody in your sample and this measurement needs to be made many times in a typical manufacturing process,” said Willson in a press release. In the realm of fluorescents, he is also working to pioneer the use of glow sticks to detect biothreats for the U.S. Navy. His discoveries include a fluorescent material that emits one color of light when excited with another color of light. Click here to read more.

How this community-focused coworking concept plans to continue growth around Houston and beyond

HOUSTON INNOVATORS PODCAST EPISODE 235

For the past five years as CEO, Jon Lambert has faced some challenges leading The Cannon — from navigating a global pandemic to the subsequent evolved real estate market. But now, the coworking and community building company is poised for even more growth — especially with its ninth location opening up this month — thanks to its community-driven mission.

The Cannon Memorial opens its doors on Monday, May 13, with a week of free coworking and events. And while the new space, developed in partnership with MetroNational, is open for leasing, Lambert says on the Houston Innovators Podcast the first and foremost, The Cannon is a community.

"The Cannon wasn't created as a real estate play — we got into coworking because as we started supporting the community and asking the question of, 'what can we do for you?,' one of the highlights was, 'hey, we need space to work,'" he says on the show. "For us, we were going to provide space because that's one of the key needs of this community.

"Our measurement of success is not the buildings we have or the occupancy even — it's what's the success of the companies that are part of the community," he continues.


Lambert shares more about The Cannon's community-focused growth by giving Fulshear as an example. The new community west of Houston isn't currently working on developing a coworking facility yet, but from a programming and digital perspective, The Cannon has established a presence.

"The first phase of the project is to just mobilize the startup and early-stage business community in Fulshear and see what kind of energy and vibe we can create there and connect them to The Cannon's resources and community," Lambert says. "That's our big-picture vision. We can build a new node of community — through a new real estate opportunity, economic development or university relationship — that's beneficial in itself, but that node gets connected to everything else."

With a recent acquisition, The Cannon has further grown its ability to engage its communities digitally. In February, Village Insights, a community management platform, was acquired by The Cannon, onboarding its core employees and further integrating the platform it was already using.

When it comes to its next expansion, The Cannon has a lot of opportunity both around and beyond Houston, Lambert says.

"Any direction is an opportunity and possibility," he says. "I would project that by the end of the year, we'll probably be having another conversation about what The Cannon's doing in other cities as well — for the benefit of The Cannon Community in Houston."

  • Friday, May 17: Cowboy Breakfast (9 to 10 am)

"As we open the doors to our next innovation focused workspace, we couldn't be more thrilled to share this moment with our community," says Jon Lambert, CEO of The Cannon. "This week marks not just the inauguration of a new physical space, but the realization of a shared vision and the culmination of an exceptional partnership with our partners at MetroNational. More than just a space, The Cannon Memorial will be an environment where innovation thrives.”

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

27 Houston companies make Fortune 500 for 2026, led by energy giants

Houston HQs

Editor's note: This article has been updated to correct the number of companies based in the Dallas-Fort Worth area.

Houston is a giant among U.S. hubs for corporate headquarters.

The 2026 Fortune 500 lists 27 companies based in the Houston area, with many energy companies claiming top spots. Houston ties with Chicago for the second-most Fortune 500 headquarters, preceded only by New York City (53). Dallas-Fort Worth is home to 24 Fortune 500 headquarters.

Texas leads the nation for Fortune 500 headquarters (57), with California in the No. 2 spot and New York at No. 3.

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

The 2026 Fortune 500 ranks the largest U.S. corporations based on revenue in fiscal year 2025.

Here’s a rundown of the 27 Fortune 500 companies based in the Houston area.

  • No. 9 ExxonMobil
  • No. 21 Chevron
  • No. 29 Phillips 66
  • No.55 Sysco

  • No. 435 CenterPoint Energy
  • No. 438 APA
  • No. 440 Comfort Systems USA
  • No. 455 NOV
  • No. 488 KBR
  • No. 496 Coterra Energy. Oklahoma City, Oklahoma-based Devon Energy and Houston-based Coterra Energy merged in early May, with the combined company retaining the Devon Energy name and the Houston headquarters.

The Greater Houston Partnership notes the Houston area soon will welcome its 28th Fortune 500 company. Expand Energy (formerly Chesapeake Energy), appearing at No. 362 on the 2026 list, says it’s moving its headquarters from Oklahoma City to Spring this year.

As the natural gas producer prepares to relocate to Texas, it’s hunting for a new leader. Nick Dell’Osso stepped down as president and CEO earlier this year. Board Chairman Michael Wichterich is interim president and CEO.

Dell’Osso became president and CEO of Oklahoma City-based Gulfport Energy effective May 28.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.
