A Houston tech company working on an engine to enable hypersonic flights has reported its latest milestone.

Venus Aerospace announced that it's successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with Defense Advanced Research Projects Agency, or DARPA.

The RDRE engine Venus is working on is uniquely designed and a first in the field. It has an additional 15 percent efficiency over traditional rocket engines.

"As we continue to push towards our ultimate mission of high-speed global flight, this is an important technical milestone for having a flight-ready engine," Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in the news release. "I'm incredibly proud of our team as they continue to push forward on this world-changing technology."

The test results are a big win, as the RDRE had previously only been tested in a short-duration capacity. DARPA is just one of several U.S. Government agencies that has contracts with Venus.

"The successful test is a testament to our team's dedication and expertise. We're building something special here at Venus, in large part because we have the right people and the right partners," Sassie Duggleby, CEO and co-founder of Venus Aerospace, adds. "I can't say enough about our collaboration with DARPA and the role they played in helping us make this leap forward."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sassie in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. Sassie joined the Houston Innovators Podcast a year ago to explain her company's mission of "home for dinner."

A Houston startup is celebrating its nationwide launch of its flagship product that coats roofs to reduce energy waste.

NanoTech's Nano Shield Cool Roof Coat is a unique product that can be added onto roofs to reduce energy waste on buildings. Co-founder and CEO Mike Francis and Chief Commercial Officer Carrie Horazeck joined the Houston Innovators Podcast to share more details about the product.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues. Continue reading.


Episode 181 - Gearing up for high-speed global travel - Sassie Duggleby of Venus Aerospace

Sarah "Sassie" Duggleby is on a mission to get people home in time for dinner — whether they are traveling around the world or working for her business. That's why she founded Venus Aerospace, which is developing hypersonic space planes. It's also why she relocated the company from the West Coast to Houston.

"We knew we had to find a location where we could test our engine and still be home for dinner," Duggleby says on this week's episode of the Houston Innovators Podcast. "Our company vision is 'home for dinner.' We want to fly you across the globe and have you home for dinner. And, if you work for us, we want you home for dinner."

Venus's technology enables this revolutionary travel through its supersonic combustion engine — more akin to a rocket's engine than an airplane's — that allows for travel at a higher elevation, she explains on the show. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally. And, as Duggleby explains, the engine can go further with the same amount of fuel, so it's a more sustainable way of traveling too. Continue reading.


Episode 182 - Stopping neurodegenerative diseases in their tracks - Howard Berman of Coya Therapeutics

When Howard Berman sought out renowned Houston Methodist researcher and neurologist Dr. Stanley Appel, he was looking for treatment for his father, who was suffering from dementia. He wasn't looking for a job, but Dr. Appel had other ideas and asked Berman to meet with him.

"I was interested in what I could do for my dad," Berman says on the Houston Innovators Podcast, explaining how he took the meeting with Dr. Appel, who then presented him with some of his research. "By slide five my jaw had hit the ground.

"He had shown that he could stop the progression in one of his early trials of ALS," Berman says.

Not too long after that meeting, Berman, who founded digital health platform imaware, joined Dr. Appel to lead commercialization of Coya Therapeutics, a biotech startup that raised over $20 million in venture funding before going public a few months ago. Continue reading.

Ramanan Krishnamoorti has had a varied career in academia, from an engineering professor to nanotech research. While he never made the transition from researcher to entrepreneur, he managed to snag a CEO title at the university about a decade ago: Chief energy officer.

Since then his role has expanded to include advancing UH's innovation of all kinds — from health tech to the arts — as vice president of energy and innovation at UH. In his role, he oversees the UH Technology Bridge, a lab and coworking space for tenants just a short drive away from UH's main campus, as well as future plans, like a new central campus hub for innovation that's in its early stages of development.

"What we really need at the university today is to bring innovation — which tech transfer is a piece of — and connect that to real-world challenges to deliver what the world needs, which is talented folks delivering new innovative, entrepreneurial, or intrapreneurial programs," Krishnamoorti says on this week's episode of the Houston Innovators Podcast.

Innovation isn't always tinkering with tech or programming software, although serial entrepreneur Erik Ibarra knows that world well. Sometimes it's about rethinking how a community improves and develops without doing the residents a disservice.

That's why Ibarra started Magnolia Fund, a mission-driven investment fund dedicated to enriching the East End community and preserving the neighborhood's culture and history. Ibarra, who has lived in the area the majority of his life, says on the Houston Innovators Podcast, that he's looking to turn residents into investors.

"Our investors from the neighborhood, today they walk around and look at their house and say, 'I own that,' and that's great," Ibarra says. "In the future, our investors should be able to say that, and then point to a building and say, 'I own a portion of that building too. And I helped that small business over there.'"

Anshumali Shrivastava's career has evolved alongside the rise of artificial intelligence. Now, he believes his company represents the future of the industry's widespread implementation.

Shrivastava, who's also a professor at Rice University, founded ThirdAI, pronounced "third eye," in 2021 to democratize artificial intelligence through software innovations. As Shrivastava explains on the Houston Innovators Podcast, AI processes have historically been run on larger, less accessible computing hardware. ThirdAI's tools are able to run on a regular central processing unit, or CPU, rather than the more powerful graphics processing unit, or GPU.

"We focus on the problems that people are facing in the current AI ecosystem," Shrivastava says on the podcast. "Right now, if you are to build some of the large-language models and (linear programming) models, you need a lot of computing power, dedicated engineers to move it, and, even if you are using fully managed services, it's costly and there are a lot of privacy implications because you have to move data around."

Houston startup with hypersonic engine tech adds new investor

it's rocket science

A Houston-based company that's developing an engine that'll enable one-hour global transportation has announced its latest investor.

Venus Aerospace released the news that Silicon Valley venture capital firm, Airbus Ventures, has joined its team of investors. The supersonic combustion engine technology — more akin to a rocket's engine than an airplane's — is revolutionary because allows for travel at a higher elevation. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally.

“Venus has developed the world’s first liquid-propellant rotating detonation rocket engine (RDRE) with a double-digit percentage increase in efficiency over standard regular engines, making the hypersonic economy possible,” says Sassie Duggleby, CEO and co-founder of Venus, in a news release. “We’re delighted to bring Airbus Ventures into the Venus family and look forward to growing our collaboration as we harness the future of hypersonic flight.”

Duggleby founded Venus Aerospace with her husband and CTO Andrew in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. That round, led by Prime Movers Lab, is being used to fund tech development and initial flight testing for building its Mach 9 hypersonic drone and Mach 9 spacecraft. Venus did not disclose how much their newest investor has contributed.

“In the world of RDREs, their pioneering approach — designing, building, and demonstrating the first liquid, storable-propellant fueled rotating detonation rocket engine — unlocks advanced aircraft capabilities and opens new vistas on our whole planetary system,” says Airbus Ventures Managing Partner Thomas d’Halluin in the release. “Venus’ compact, low mass, high efficiency engine capability will have an immediate impact on lunar and martian landers, space mobility and logistics, and deep space mission proposals.

"Here on Earth today, we will see unprecedented performance gains for drones of all kinds, and more practical and faster-than-anticipated opportunities for ultra-high-speed passenger and cargo rocket plane flights,” he continues.

Venus, which as has contracts with NASA and US Defense Agencies, has plans to test its technology this summer at its headquarters in the Houston Spaceport.

“With the strong support of Airbus Ventures now joining our investor syndicate, our next round will let Venus take the final step from lab to prototype as we fly our drone to Mach 3 under RDRE power," says Andrew Duggleby, in the release. “This will include long-duration engine runs this summer at Spaceport Houston, as well as the design, build, and flight of our drone with the broader Venus team and our incredible partners.”

Houston aerospace startup secures $20M series A investment round

money moves

A year after raising $3 million in seed funding, a Space City startup has closed its high-flying series A round to the tune of $20 million.

Venus Aerospace, which is working on a zero-carbon emission spaceplane that will enable one-hour global travel, closed its series A funding round led by Wyoming-based Prime Movers Lab. The firm has a few dozen breakthrough scientific companies in its portfolio, including another Houston-based, space-focused startup, Axiom Space. The round also saw participation from previous investors: Draper Associates, Boost, Saturn 5, Seraph Group, Cantos, The Helm & Tamarack Global.

Venus Aerospace was founded by Sarah "Sassie" and Andrew Duggleby, who serve as the company's CEO and CTO, respectively, in 2020 in California. The Texas A&M University alumni later moved the business into its current facilities in the Houston Spaceport.

"The U.S. is in the middle of a global race for hypersonic technology, and the breakthroughs being developed by Sassie, Andrew, and their team have numerous civilian and defense applications," says Prime Movers Lab General Partner Brandon Simmons in a news release. "Venus hit critical engine tests, vehicle design, and growth milestones that make me tremendously excited about the future of American hypersonic flight."

According to the release, the company will use the fresh funding on enhancing its three main technologies: a next-generation rocket engine, aircraft shape, and leading-edge cooling system, which allows for the Venus spaceplane to take off from existing spaceports.

"These recent advances in technology finally enable a spaceplane, a vehicle long imagined, but only now possible," says Andrew Duggleby in the release. "We will use this round of funding to get into flight testing and engine testing at Spaceport Houston. Bringing this technology forward into systems, drones and ultimately spaceplanes, it will take both new space veterans and bright new minds to solve. We've gone from impossible to hard, and this investment will allow us to knock down the next few steps."

The past year has represented significant growth for Venus, with developing contracts with the government and building out the company's team — and the company still has eight positions listed on its website. After building out and testing its technology, Venus also started a ground test campaign at Spaceport Houston.

"We are excited to continue our partnership with Prime Movers Lab and our other great investors. In the past year, with our initial funding, we have scaled from 3 people to 40. These are the world's best rocket scientists, engineers, and operators," says Sassie Duggleby in the release. "With this funding, we will continue to push forward toward our next technical milestones, hire great people, and scale our organization. We are excited to continue engineering the future of high-speed aviation."

Overheard: Houston's top energy transition founders explain their biggest challenges

Houston Innovation Awards

From finding funding to navigating the pace of traditional oil and gas company tech adoption, energy transition companies face their fair share of challenges.

This year's Houston Innovation Awards finalists in the Energy Transition category explained what their biggest challenge has been and how they've overcome it. See what they said below, and make sure to secure your tickets to the Nov. 14 event to see which of these finalists win the award.

"The evolving nature of the energy industry presents opportunities to solve some of our industry's greatest challenges. At Amperon we help optimize grid reliability and stability with the power of AI demand forecasting."

Sean Kelly, CEO of Amperon, an AI platform powering the smart grid of the future

"The biggest challenge in leading an energy transition-focused startup has been balancing the urgency for sustainable solutions with the slow pace of change in traditional industries like oil and gas. Many companies are cautious about adopting new technologies, especially when it comes to integrating sustainability initiatives. We overcame this by positioning our solutions not just as environmentally friendly, but as tools that improve safety, efficiency, and cost savings. By aligning our value proposition with their operational goals and demonstrating real, measurable benefits, we were able to gain traction and drive adoption in industries that are traditionally resistant to change."

— Dianna Liu, CEO of ARIXTechnologies, an integrated robotics and data analytics company that delivers inspection services through its robotics platforms

"Scaling up production of hard tech is a major challenge. Thankfully, we recruited top-notch talent with experience in technology scale-up and chemical processes. In addition, we've begun building partnerships with some of the world's largest chemical manufacturers in our space who are excited to be a part of our journey and could rapidly accelerate our go to market strategy. We have significant demand for our product as early as 2025, so partnering with these companies to scale-up will bring our technology to market years ahead of doing it alone."

— Matthew Dawson, CEO of Elementium Materials, a battery technology with liquid electrolyte solutions

"Our pyrolysis reactor is a proprietary design that was developed during Covid. We ran simulations to prove that it works, but it was not easy to test it in a pilot facility, let alone scaling it up. We managed ... to run our pilot plant studies, while working with them remotely. We proved that our reactor worked and produced high quality products. Later, we built our own pilot plant R&D facility to continue running tests and optimizing the process. Then, there was the challenge of scaling it up to commercial size. ... We put together a task force of four different companies to come together to design and build this complex reactor in record time."

— Vibhu Sharma, CEO of InnoVentRenewables, a startup with proprietary continuous pyrolysis technology that converts waste tires, plastics, and biomass into valuable fuels and chemicals

"Energy storage and geothermal power generation are capital-intensive infrastructure projects, requiring investors with a deep commitment and the patience in terms of years to allow the technology to be developed and proven in the field. One challenge is finding that niche of investors with the vision to join our journey. We have succeeded in raising our $30 million series A with these types of investors, whom we’re confident will continue the journey as we scale."

— Cindy Taff, CEO of SageGeosystems, an energy company focused on developing and deploying advanced geothermal technologies to provide reliable power and sustainable energy storage solutions regardless of geography

"The biggest challenge we've faced has been to bring together massive independent power producers on one side who are investing hundreds of millions of dollars into grid infrastructure with multi- national tech giants on the other that don't have experience working much with energy storage. As a startup with only four employees, gaining credibility with these players was critical. We overcame this hurdle by becoming the preeminent thought leader on storage emissions, through publishing white papers, discussing the issues on podcasts, and (more)."

— Emma Konet, CTO of TierraClimate, a software provider that helps grid-scale batteries reduce carbon emissions
