It’s not easy to be a standout at South by Southwest, especially during SXSW Interactive, which is the subsection of the festival that focuses on new media, technology and entrepreneurship.

But it’s even more difficult to win at SXSW Pitch, the competition for startups and entrepreneurs that showcases innovative new technology to a panel of industry experts, high-profile media professionals, venture capital investor, and angel investors.

Tempest Droneworx, a Houston-based company that provides real-time intelligence collected through drones, robots and sensors, did just that in March, taking home the Best Speed Pitch award. It was also named a finalist and alternate in the full SXSW Pitch competition. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine.

Tempest CEO and founder Ty Audronis says his company won based on its merits and the impact it’s making and will make on the world. Audronis founded the company after his hometown of Paradise, California, was destroyed by a wildfire in 2018.

“(SXSW) was a huge moment for our team,” says Audronis, whose background is in science visualization, data visualization and visual effects for the movie industry. “This is about what everyone at Tempest Droneworx has created, and our mission to make sure that issues—like the one that befell Paradise, California, my hometown, and the inspiration for our Harbinger software—don’t become the full-blown (disasters)."

Audronis shares that the company is working to release an agriculture beta this summer and is raising a Tactical Funding Increase (TACFI) round through the AFWERX, the Department of the Air Force’s innovation arm.

Tempest’s Harbinger is impressing investors and clients alike, but what is it exactly and what does it do?

The best way to explain the solution is in how it’s redefining the agriculture space. Tempest has deployed the product at Grand Farm in North Dakota, an agtech operation that seeks to promote sustainable, climate-resilient farming using applied technology.

“We decided to go down the road of agriculture,” Audronis says. “We're currently installed at the Grand Farm in North Dakota, which is a farm that is very closely tied to Microsoft. They do third-party verification of new soils and fertilizers, and we are helping them with visualizing the data that they're getting from their sensors.”

Additionally, Audronis and his co-founder and wife, Dana Abramovitz, spearhead a pilot program at Doubting Thomas Farms, an organic farm in Minnesota, where the company has installed 22 in-ground sensors that can measure volatile organic emissions.

To further optimize their solutions approach, Tempest Droneworx will also train artificial intelligence to look for overspray from neighboring non-organic farms. This will help maintain organic certification and reduce insurance claims for lost crops.

“This will save Doubting Thomas Farms and other organic farms a boatload of cash,” Audronis says.

During an exclusive tour with InnovationMap, Audronis pulled up a live feed of sensors buried around the Minnesota farm up on the conference room display. The feed did, in fact, look like a video game, with the sensors giving real-time data about the farm’s temperature, moisture level, humidity, CO2 and nitrogen.

Harbinger will collect, extract and extrapolate all of the data and later provide a digital almanac for farmers to track the history of their crops.

As the office tour continued, Audronis pointed out the company’s expanding partnership with the U.S. Military.

As a retired U.S. Navy veteran with over two decades of experience designing, building and piloting drones, Audronis understands that Harbinger has multiple military applications that will ultimately save lives—a core tenet of his company’s mission.

The company has launched a robotic dog known as UBU, developed by Tempest partner Ghost Robotics, that enables faster, more accurate ground surveys for explosive devices. This task previously required multiple airmen and hours to complete, Audronis says.

With agriculture and military initiatives in progress and making an impact, Audronis hopes to one day bring his original vision for Tempest Droneworx and Harbinger full circle by getting the call to combat California’s next catastrophic wildfire.

“We're proving our technology in military and in agriculture right now,” Audronis says. “Eventually, I would like to still save some lives with wildfire. That's really the purpose of the company … Whether it's agriculture, smart cities, the bottom line is saving lives through real-time situational awareness."

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 drones to energy tech— recently making headlines in Houston innovation.


Madison Long, co-founder and CEO of Clutch

Houston-based creator economy platform Clutch — founded by CEO Madison Long and CTO Simone May — celebrated its nationwide launch earlier this month. The platform connects brands to its network of creators for reliable and authentic work — everything from social media management, video creation, video editing, content creation, graphic design projects, and more.

When the company first launched its beta in Houston, the platform (then called Campus Concierge) rolled out at three Houston-area universities: Texas Southern University, Rice University, and Prairie View A&M. The marketplace connected any students with a side hustle to anyone on campus who needed their services.

Long shares on this week's Houston Innovators Podcast that since that initial pilot, they learned they could be doing more for users.

"We recognized a bigger gap in the market," Long says. "Instead of just working with college-age students and finding them side hustles with one another, we pivoted last January to be able to help these young people get part-time, freelance, or remote work in the creator economy for businesses and emerging brands that are looking for these young minds to help with their digital marketing presence."

Ty Audronis, fueled by wanting to move the needle on wildfire prevention, wanted to upgrade existing processes with real-time, three-dimensional, multi-spectral mapping, which exactly where his company, Tempest Droneworx, comes in.

That software is called Harbinger. Audronis explains that the real-time management and visualization solution is viewable on practically any device, including mobile or augmented reality. The system uses a video game engine for viewing, but as Audronis puts it, “the magic happens” on the back end.

The company was just the two founders until five weeks ago, when Tempest’s size doubled, including a full-time developer. Once Tempest receives its SIBR check, the team will grow again to include more developers. They are currently looking for offices in the city. As Audronis says, Tempest Droneworx is “100-percent made in Houston.” Read more.

Greentown Labs named a new member to its C-suite. Juliana Garaizar, who originally joined Greentown as launch director ahead of the Houston opening in 2021, has been promoted from vice president of innovation to chief development and investment officer.

"I'm refocusing on the Greentown Labs level in a development role, which means fundraising for both locations and potentially new ones," Garaizar tells InnovationMap. "My role is not only development, but also investment. That's something I'm very glad to be pursuing with my investment hat. Access to capital is key for all our members, and I'm going to be in charge of refining and upgrading our investment program."

While she will also maintain her role as head of the Houston incubator, Greentown Houston is also hiring a general manager position to oversee day-to-day and internal operations of the hub. Garaizar says this role will take some of the internal-facing responsibilities off of her plate. Read more.

Growing Houston-based drone software company snags government contract

ready for liftoff

Ty Audronis quite literally grew up in Paradise. But the Northern California town was destroyed by wildfire in 2018, including Audronis’ childhood home.

“That’s why it’s called the Campfire Region,” says the founder, who explains that the flames were started by a spark off a 97-year-old transmission line.

But Audronis, who has literally written the book on designing purpose-built drones — actually, more than one — wasn’t going to sit back and let it happen again. Currently, wildfire prevention is limited to the “medieval technology” of using towers miles apart to check for smoke signals.

“By the time you see smoke signals, you’ve already got a big problem,” Audronis says.

His idea? To replace that system with real-time, three-dimensional, multi-spectral mapping, which exactly where his company, Tempest Droneworx, comes in.

When asked how he connected with co-founder Dana Abramowitz, Audronis admits that it was Match.com — the pair not only share duties at Tempest, they are engaged to be married. It was a 2021 pre-SXSW brainstorming session at their home that inspired the pair to start Tempest.

When Audronis mentioned his vision of drone battalions, where each is doing a specialized task, Abramowitz, a serial entrepreneur and founder who prefers to leave the spotlight to her partner, told him that he shouldn’t give the idea away at a conference, they should start a company. After all, Audronis is a pioneer in the drone industry.

“Since 1997, I’ve been building multicopters,” he says.

Besides publishing industry-standard tomes, he took his expertise to the film business. But despite its name, Tempest is a software company and does not make drones.

That software is called Harbinger. Audronis explains that the real-time management and visualization solution is viewable on practically any device, including mobile or augmented reality. The system uses a video game engine for viewing, but as Audronis puts it, “the magic happens” on the back end.

Harbinger is not just drone-agnostic, but can use crowd-sourced data as well as static sensors. With the example of wildfires in mind, battalions can swarm an affected area to inform officials, stopping a fire before it gets out of hand. But fires are far from Harbinger’s only intended use.

The civilian version of Harbinger will be available for sale at the end of 2023 or beginning of 2024. For military use, Navy vet Audronis says that the product just entered Technical Readiness Level (TRL) 5, which means that they are about 18 months away from a full demo. The latest news for Tempest is that earlier this month, it was awarded a “Direct to Phase II” SBIR (Government Small Business Innovation Research) contract with the United States Department of the Air Force.

Not bad for a company that was, until recently, fully bootstrapped. He credits his time with the Houston Founder Institute, from which he graduated last February, and for which he now mentors, with many of the connections he’s made, including SBIR Advisors, who helped handle the complex process of getting their SBIR contract.

And he and Abramowitz have no plans to end their collaborations now that they’re seeing growth.

“Our philosophy behind [our business] isn’t keeping our cards close to our vest,” says Audronis. “Any potential competitors, we want to become partners.”

The company was just the two founders until five weeks ago, when Tempest’s size doubled, including a full-time developer. Once Tempest receives its SIBR check, the team will grow again to include more developers. They are currently looking for offices in the city. As Audronis says, Tempest Droneworx is “100-percent made in Houston.” Paradise may have been lost, but with Harbinger soon to be available, such a disaster need never happen again.

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

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 23 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.

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.
