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, co-founder of Tempest Droneworks

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.

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.”

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
