While being renown as the energy capital of the world, Houston doesn't have an active oil and gas-focused accelerator program for the various startups rising in the energy industry. That is, until now.

Houston-based BBL Ventures, an early stage capital fund for energy startups, has announced BBL Labs, a new accelerator is based in Station Houston. BBLL is accepting applications for its inaugural cohort by February 22.

"BBLV looks forward to engaging in this partnership to drive entrepreneurial innovation focused on identified challenges and technology gaps in the global energy and natural resources industry," says Patrick Lewis, managing partner at BBLVentures, in a release.

BBLL will use BBLV's data on what the oil and gas industry needs from new tech startups as well as its connections to big energy companies to better connect the dots within the accelerator program.

Historically, tech startups focused on oil and gas solutions have a lot of trouble finding funding and validation in the industry — for a few reasons, Lewis says. On one hand, there's a disconnect between oil and gas companies and the startups that have solutions to industry problems, and on the other, the VC funds aren't there.

"Energy tech is a grossly underfunded industry. Venture capitalists hate it — the hyper cyclical industry, extremely long sales cycles, slow adopters — but that creates opportunities," Lewis says.

So what BBL's venture arm has done is flip the script on this way energy startups and big oil companies have traditionally functioned. Currently, it's up to the energy startups to tell large energy companies why their company or industry needs new technology to solve a problem. But what BBL has realized with it's venture arm is that it's much more efficient if the industry figures out its greatest technology needs and then looks for companies solving that problem. To do that, BBL's Innovation Navigator Software acts as a tool for energy employees to identify pain points.

"We've built software that's meant to be used pervasively across the organization — from the drilling engineer out in the field to the global office manager to the CTO," Lewis says.

These employees can log their daily pain points in the system, categorize them, and flag their priority. BBL takes that information, develop a reverse pitch, and market it to the startup ecosystem globally to identify companies that are addressing the problems of these energy employees.

BBL will use this proprietary pain point data to drive the new accelerator to produce a cohort of 10 startups creating technology that oil and gas companies have already indicated they need. Each cohort will go through six months of programing located in Station Houston. The two entities will collaborate on resources including lab space, investment, advisory services, mentorship, and more.

"Station Houston exists to support startups and with BBL Labs now inside our four walls, we can offer the Houston startup community access to even more resources and support," says Station CEO Gabriella Rowe. "At the same time, our 130 mentors are ready to roll up their sleeves and help these businesses get off the ground and start making an impact."

Canadian startup fresh off $7 million seed funding raise picks Houston for U.S. expansion

Energy Tech

Houston's established reputation as the energy capital of the world combined with burgeoning tech scene has made the city attractive for a growing oil and gas company with roots in Canada.

Validere is an oil and gas company focused on using real-time data and both artificial and human intelligence insights to improve its clients' quality, trading, and logistics. The company's technology enhances the ability of oil and gas traders to make informed decisions, which currently are made based off unreliable product quality data. Annually, $2 trillion of product moves around the oil and gas industry, and Validere uses the Internet of Things to improve the current standard of decision making.

"It's like if you'd go to the grocery store to buy milk not knowing if it's 1 percent, 2 percent, or cream," co-founder Nouman Ahmad says about how companies are currently making oil and gas trading decisions.

In October, Validere concluded its seed funding round with $7 million. Among Validere supporters are several Silicon Valley power players, such as Sallyport Investments, Y Combinator, Real Ventures, Moment Ventures, and ZhenFund. The funds, in part, will help the company expand into the United States market.

"The goal in 2019 is to be at the same stage — in terms of customer success — in the U.S. market as we were at the end of 2018 in the Canadian market," Ahmad says.

The company has seen great success in Canada, and some of its existing clients have business in the Houston area already, Ahmad says.

With the increased focus on Houston comes a growing office. Currently, Ahmad leads the efforts in town with one other staffer, however, operations won't be a skeleton crew for too much longer. Ahmad says he is "aggressively hiring" in the Bayou City, which will be a key office for them as they grow across the country.

"As we think about the long-term future of the business, Houston is one of the most important markets for us going forward," Ahmad says.

Houston has been a welcoming community to the Canadian transplant, who says he spends most of his time here now. Both the startup and tech scenes in Houston have been valuable resources to the company — as has the energy industry's potential clients.

"Houston market is very receptive and ready for innovative companies that are solving problems for them," Ahmad says.

The company was founded in 2015 at Harvard by entrepreneurs who saw the potential for better transparency in the oil and gas industry. Validere's other co-founder and CTO, Ian Burgess, first had the idea for the technology after an accident happened in Canada; a train carrying crude oil derailed and blew up a small town killing 45 people.

"The industry largely bases important operational decisions on poor quality data," Burgess says in a release. "Our platform not only informs product quality reliably and in real time, but it also uses AI to help oil and gas companies optimize product movement."

Houston tech company aims to make campuses more secure with tracking device

Can't pass this up

There's an only public service announcement from the 1960s that asks, "It's 10:00 p.m., do you know where your children are?" The idea behind it was to encourage parents to ensure their children's safety, by encouraging them to be home before what was then the youth curfew in several states.

"Do you know where your visitors are right now?" asks the SafePass website, providing an answer: "You do if you have SafePass."

The visitor management system is the brainchild of Ronald Huff, who initially envisioned the system as a hall pass for students. The electronic pass would monitor students in real time, if they left class to go to the nurse or the restroom, meaning adults would be able to find them in the event of an emergency. But as Huff and his business partners proceeded through product development, they realized SafePass had a stronger lure as a system that could manage visitors across several platforms – business, schools, and secure environments.

The system works like this: companies issue a SafePass visitor badge to visitors, contractors or others who are temporarily on the grounds of their facilities. The badge records signal strengths from WiFi routers set up around the facility and tracks where the visitor is in real time.

"Visitors don't know a facility as well as the people who work there every day do," said Huff. "If there's smoke or a fire, they might get lost. So, SafePass helps provide a record of where they are, meaning that people can find them if there's an emergency or an evacuation."

SafePass is also reusable. The electronic badge is designed to be used over and over again, unlike common printed paper badges that visitors stick on.

"We're 100 percent eco-friendly," said Huff.

He and his partners built the demo for the product at the end of 2017 and began shopping it at trade shows. The reaction was immediate, with multiple companies wanting to take on the system. SafePass is about to launch a pilot phase with some Fortune 100 companies, and has plans to expand soon beyond that.

Companies can currently email their floor plans to SafePass, which creates routes within the floor plans, fixing geolocations. Then the signal strength from WiFi routers is digitally mapped within the building using an Android app. This allows the electronic badge to know where a guest is as he or she is traveling throughout a given facility.

"I think most people know that cell phones record almost everything we do," said Huff, explaining that SafePass isn't designed to infringe on personal privacy. "This isn't a Big Brother situation. Above all else, we're concerned about the safety of both people who are visiting a facility and those who work there every day."

Huff said SafePass can also help companies with safety and security compliance. For instance, oil and gas companies are audited by third parties on how secure their facilities are. SafePass' technology helps them not only score higher on an audit, but actually keep their facilities secure.

"A product like ours solves so many different problems," he said.

After nearly two and half years of development, Huff said he's excited about what's to come.

"This is really my baby," he said of the company. "And it's been such a blessing to work with this team of developers and programmers and sales people. We've got a great team and great clients. This is a dream come true."

SafePass has made a splash on the Houston digital innovation scene and was even named one of the most promising startups at the recent Texas Digital Summit.

Houston electronics manufacturing company gears up for growth

On the line

It takes an unnecessarily long time for electronic devices to get from idea to reality — and much of that is due to inefficiency in manufacturing. Just getting a prototype together takes weeks of back and forth between the engineer and the manufacturer.

"The business model for contract manufacturing hadn't changed in 30 years," Chris Church says. "It was phone calls, emails, going out and playing golf, going to lunch, and negotiating everything endlessly."

Houston-based MacroFab is addressing these antiquated and outdated ways of manufacturing and changing the way electronics manufacturing is done. For its revolutionary work, the company has consistently seen its revenue at least double — sometimes tripling or quadrupling — every year, and projects to at least triple in 2019.

Addressing an underserved market
Church — who has a background in hardware development, specifically within robotics — created MacroFab in 2013 and launched the platform in 2015. Misha Govshteyn joined the board in 2014 and became CEO last summer. The duo co-founded cloud-based security-as-a-service company, Alert Logic, in Houston in 2002.

Using its custom software, MacroFab enables customers to upload their designs through the website, where they can then receive projected timeline and pricing information from the get go. The company has its own manufacturing area in its office for prototypes and small orders, but its network of large manufacturers is a key part of the MacroFab's growth equation.

The company has about 20 manufacturing plants as partners that can pick up manufacturing jobs from MacroFab customers when the plant has space on its lines up for grabs. Rather than let available capacity go to waste, these plants can easily pick up the design and materials to start production.

"It's not dissimilar to what Uber is doing with cars — there's a lot of people with cars that could give you a ride if they knew you were out there," Govshteyn says. "It's that matchmaking function is essentially what we're doing with our customers."

The manufacturing partners benefit from jobs they otherwise wouldn't have, and the MacroFab customers get access to a plant that they didn't have to do the legwork to find. Govshteyn says a he's heard horror stories from people who had orders that were unceremoniously dropped by a manufacturer because another one of its clients just placed a large order.

"That shouldn't happen. If a factory gets too busy, it should be easy enough to take that job and move it somewhere else," Govshteyn says. "But, right now, there's not a way to do that."

Using cloud technology, the MacroFab platform can easily share the design and translate it to any given factory, Church says. They also have a technology that combine smaller orders together so there's no wasted resources, which brings down the cost for the customer.

While usually a company might have to find a new manufacturer as they scale up and start making larger orders, MacroFab customers don't have to start from scratch to find a new plant that can take their order — MacroFab will do the matchmaking for them.

"We've created and are continuing to build a marketplace for excess manufacturing capacity," Church says.

MacroFab owns the customer experience and the sales aspect — ensuring a more positive and consistent experience — while the manufacturers can just take the jobs and go.

Scaling up
The manufacturing marketplace is a newer focus for MacroFab — the company just launched it in beta this year — and is a big proponent of the company's growth. Before, the company was limited to what it could produce in its own factory taking on prototype and small orders. Now, with access to the manufacturers, the company has served 1,700 customers, building 500,000 units for about 4,000 different products. Those figures, Church says, are scaling up so rapidly as they expand to new partners.

"This is the first quarter where more gets produced outside of our factory than inside of it," Govshteyn says. "By this time in Q1, 75 percent of our revenue will [come from outside manufacturing plants.]"

Since manufacturing plants haven't historically collaborated, Govshteyn says the reception from manufacturers has been "cautiously optimistic." But then they realize they are getting customers for free — all they have to do is meet the requirements and deliver on time, he says.

"It's great for them to see that their factory is only half used, but then they can fill it up with jobs from MacroFab," Govshteyn says.

Houston has been a great city for MacroFab with its port manufacturing and logistics, two things Govshteyn says MacroFab is focusing on.

"At the end of the day, we're a manufacturing company, and I think we'll dabble in logistics," he says. "There's a lot worse places to start a logistics-heavy company."

Houston company has sight set on AR solutions for industrial construction

Visual aid

When Lori-Lee Emshey got her first oil and gas construction job in Australia, she was carrying around a backpack full of papers.

"I was really shocked at how much work they were doing with such little technology," Emshey says. "I thought, 'there's so much room for innovation here.'"

She realized that it wasn't just that site or the company she was working for — this was a problem across the industry. So, she came up with a solution. Houston-based Future Sight AR is an augmented reality technology to more efficient work on industrial construction sites. Workers can use a smart device in the field, point it at a problem on site, log the issue, and see the steps needed to fix it.

Constructing a company
Emshey realized the potential for a company in January 2016. Since then, she's partnered up with her co-founders, Sofia Lazaro and Veena Somareddy, attended accelerators and conferences across the country, completed a proof of concept, until finally incorporated this year.

It was a well-paced start for the company because they got to prove time and time again there was a need for the company. Emshey says she never wanted to start a company just to start a company. They worked tirelessly at the beginning to ensure there was no one out there already doing this in the way they were doing it.

"I feel like a lot of entrepreneurs now become an entrepreneur because it's trendy and cool, and you want to put it in your Instagram bio," she says. "The three of us aren't like that. We did this because we had to. It wasn't going to get done another way, and we couldn't let this giant opportunity float on by."

Once they got a firm footing, one of the challenges they faced was communicating the company's market need and how the technology works to individuals outside the industry. For Emshey, this was particularly annoying.

"I came from a journalism background, and it's storytelling," she says. "I thought, 'I should be able to do this.'"

Something eventually just clicked, and Emshey stopped seeing confused faces in response to her presentation, and she started seeing more head nodding. However, another challenge she says she occasionally faces is how she looks.

"It is tough. I'm pitching this industrial construction startup, and I show up and I'm a 5-foot-5 blond woman," she says. "And some people don't care, and some people would prefer I looked a different way."

Foreseeing the company's future
Raising capital has been the latest focus for Future Sight AR. Aside from some grants and accelerator money, the company hasn't raised much. They've only just started meeting with investors and have a plan to launch a round of fundraising next year. Emshey also says they are looking to partner with three companies to conduct a few pilots early next year.

It's a great time in technology for Future Sight AR as more and more people are using AR and virtual reality. People use AR or VR often — in SnapChat filters or through Pokemon Go!

Emshey says she thinks VR will grow first in gaming, while AR will take off through enterprise.

"Unlike VR when you're completely immersed, in AR, you're seeing your actual environment and one of the places you have to do that is at work," Emshey says.

Whether it's through being acquired or growing the company on its own, Emshey says she wants Future Sight AR to evolve the industry as a whole.

"If we could permanently change the way that we build projects — oil and gas or another industry — and move it toward something more efficient, safer, more productive, and a better experience for workers, and accomplish that in a permanent way in a permanent way, then we're successful," she says. "We really built this for me — I was the worker out in the field trying to do things, and it was unnecessarily difficult."

4 financial concerns to keep in mind when launching a startup

Must be the money

You have been working on a new creative technology idea for months, an idea that will solve a problem or make a current process even better. Your innovative idea is ready for the next step, and you, in turn, are prepared to begin your tech startup. Building a company can be stressful and exhausting, but also exhilarating and rewarding. As you begin your product launch, keep these financial tips in mind when starting out.

Consider your funding
Determine how much funding you can use from your personal accounts to jumpstart your business. By investing some of your own money into your company, you show good faith in your business plan and product. This method is appealing to investors because it shows you have a long-term commitment to the company. Next, determine how much you will need from other sources and what those other sources should be. Potential options of funding in addition to traditional bank loans are venture capitalists, angel investors, government grants, and support from business incubators.

Determine your budget
An essential step of starting up is concluding how much funding you need to get started. Establishing a realistic budget is crucial. It can make the difference between having a successful business or joining the 50 percent of small businesses that fail in the first four years. The hiring of employees, leasing office space or lab space, purchasing office equipment, paying for insurance (health and liability) and providing yourself a salary are all items that need to be included in your budget.

Unanticipated extra costs occur from time to time, so overestimate your expenses. Underestimating expenses can sink your startup. Ensure your business is solvent by preparing your budget for more. Additionally, keep in mind different types of expenses, and budget accordingly. For example, you may have one-time costs and on-going costs or fixed costs and variable costs.

Cash flow
According to a U.S. Bank Study, 82 percent of businesses that fail do so because of cash flow problems. Managing your cash flow is crucial to success. Without positive cash flow, you are not able to pay your employees, rent, or taxes. Having profits does not necessarily mean you have positive cash flow. Keep ongoing cash flow work sheets to ensure you have the cash you need to continue on a successful path.

Managing for life
As mentioned earlier, make sure you pay yourself something. It does not have to be a big salary in the beginning, but you need to eat. Additionally, you need to save for emergencies. An old rule of thumb states that an emergency fund should consist of three to six months' worth of expenses. As a result, an emergency fund can make the months where business is slow, or between projects, more sustainable.

Meanwhile, it is a good idea to separate your personal and business banking accounts. Doing so will allow you to stay more organized and help tracking and managing expenses easier. Additionally, separate accounts may be beneficial when paying taxes. Consult a tax professional for additional guidance on taxes. Finally, do not forget to save for your retirement. While it is important to focus on your new business, do not neglect to take care of your personal financial health.

With proper planning and continued financial monitoring, starting your own tech business can be done well and bring years of career satisfaction.

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. 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.
