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."

Houston startup with next-gen farming tech calls for crowdfunding as it plans to grow

seeing green

Whether it’s on Mars or at the kitchen table, entrepreneur Bart Womack wants to change what and how you eat.

But the CEO and founder of next-generation farming startup Eden Grow Systems is seeking crowdfunders to help feed the venture.

The company evokes images of a garden paradise on earth. But the idea behind the Houston-based NASA spinoff came from a more pragmatic view of the world. Womack’s company sells indoor food towers, self-contained, modular plant growth systems built on years of research by NASA scientists looking for the best way to feed astronauts in space.

The company has launched a $1.24 million regulated crowdfunding campaign to raise the money it needs to scale and expand manufacturing outside the current location in Washington state.

Additionally, the U.S. Air Force recently chose Eden as a food source for the U.S. Space Force base on remote Ascension Island, in the Atlantic Ocean, Womack tells InnovationMap. Another project with Space Center Houston is also in the works.

“We want to be the government and DOD contractor for these kind of next-generation farming systems,” he says.

The Houston-based company includes former NASA scientists, like recent hire Dr. L. Marshall Porterfield, of Purdue University, as an innovation advisor.

Womack, a former digital marketer, Houston public channel show host, night club owner and entertainment entrepreneur, left those ventures in 2012, after the birth of his first child. While taking a year to study trends research, in 2014, what he read intrigued and alarmed him.

“I’ll never forget, I came across a report from Chase Manhattan Bank….of the top 10 disruptive investment sectors, over the next decade,” he says. “At the very top of the list was food.”

His conclusions on the fragility of the world’s food supply system, due to overpopulation, and scarcer land, led him to launch Eden in 2017, funded by venture capital firm SpaceFund, Womack, his family, friends and angel investors.

Womack believes “black swan” events will only increase, disrupting the food supply system and further jeopardizing food supplies.

“We’re going to enter a period of hyper novelty in history,” Womack says.. "The system we’ve built for the last 100 years, the super optimized system, is going to begin to break apart."

To avert a centralized food production outcome, operated by corporate giants like Amazon or Walmart, Womack’s vision offers a decentralized alternative, leaving it in local hands.

With $2 million put into the company so far and a half million-dollars in sales last year, Womack argues that Eden has achieved much and can make food independence within reach for everyday families.

The company commercialized NASA technology to fill what it viewed as “a huge gap within the controlled…agricultural space.”

The tower is the building block of a modular, automated and vertical indoor plant growth system, with calibrated misting, fans, and LED lighting, controlled by an app.

The company website touts the towers as an easy way to grow plants like lettuce, carrots, tomatoes, and potatoes, with little water, no soil, and lots of air, without the expense and work of cultivating an earth-based garden.

For those who want to eat more than greens, the towers provide a way to breed fish and shrimp in an aquaponic version, recycling fish waste as plant fertilizer.

However, big plans come with big costs. The towers range in price from $5,000 to $7,000, although payment plans for those who qualify make it affordable.

Eden has sold around 100 of their towers so far, to a variety of customers. But rising costs and shipping delays have led to a a three-month backlog.

The manufacturing and shipping associated with larger installations means that even if the company made a million-dollar sale, delivery of the product would take a year.

“One of the hardest things…as a start-up, the last couple of years, is trying to narrow down exactly where the biggest payback is,” Womack says. “There is the lower hanging fruit, of small sales to individual buyers, but there’s the larger fruit of institutional buyers. But they can take months and years to convert into an actual buyer.”

Customers include several universities, including Texas A&M University and Prairie View A&M University, and talks are underway with other large academic institutions.

For now, attracting investors so the company can reach its funding goal poses the biggest challenge.

“Texas investors are very, very hard-nosed, and they’re not like West Coast investors. They want to understand exactly how they’re going to get their money back, and exactly how quickly,” he says.

Womack says the crowdfunding round would allow the company to expand manufacturing operations into Houston, deliver product faster, and invest in advertising.

“When we complete this round, and become completely self sufficient, we’re planning on moving to a $25 million valuation,” Womack says. “We can show, given money, we can scale the company.”

The city of Nassau Bay, next to NASA’s Johnson Space Center, has purchased towers and plans to purchase more, not for the production of food, but to grow ornamental flowers.

Womack says that city officials there found that it’s cheaper to grow the decorative plants themselves, rather than buying them.

The towers are adaptable, and can grow not only food but cannabis and other plants, and if buyers want to use them other purposes, that adds to the product’s appeal, Womack says.

Eden has also sold some towers to Harris County Precinct 2 and the city of Houston, as part of a project he says will turn food deserts throughout the area into “food prosperity zones.”

“Our goal is to be the farming equivalent of Boeing,” Womack says.

Houston-based, NASA-founded cleantech startup closes $12M seed round

Fresh Funds

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.
