In two months, a couple Houston companies will be packing their bags and headed for Austin, where they will pitch their startups at the 11th annual SXSW Pitch event. SXSW announced the 50 finalists on Wednesday.

A total of six Texas companies — two from Houston and four from Austin — will be presenting to a live audience and panel of judges at the March 9 to 10 competition. There are 10 categories, each with one winner, as well as an overall "Best of Show" winner.

Houston-based Fluidity Technologies will be presenting as its drone controller, FT Aviator, has been named a finalist in the Hyper-Connected Communities category. Fluidity is lead by CEO Scott Parazynski, a former NASA astronaut, pilot, and physician. The FT Aviator has the potential to revolutionize drone technology. The joystick-like controller is based off movement in space, Parazynski says, and is less prone to user error by someone not as well trained in drone operation.

"I've flown aircraft and spacecraft," Parazynski says in an InnovationMap article about the company. "But none allowed for the precision of motion I was looking for. None prevented unintended motion."

The other Houston company selected as a finalist is Zibrio SmartScale, which is in the Health and Wearable category. The company is all about balance. Its product, a smart scale that tracks balance, aims to reduce dangers that come with poor balance — injuries, deaths, and costs from falls. Katharine Forth leads the company as CEO and founder. The company was a member of TMCx's 2015 medical devices cohort.

SXSW's competition this year has expanded to include new categories and has seen an increase in startups.

"We have seen a 42 percent rise in applicants coming out of last year's event, and we couldn't be more thrilled to see such an impressive increase in the value of SXSW Pitch among the tech industry's most innovative startups," says SXSW Pitch Event Producer Chris Valentine in the release. "In addition to the creation of the new AI and blockchain categories, we've also expanded our advisory board to highlight geographic, gender, and racial inclusion – accelerating our desire to represent the world's most innovative and successful leaders in all areas of technology."

It's not just in the finalists that Houston is represented — two advisers are from the Bayou City. Mariam Jacob, of Allergy and Asthma Clinics of Houston, will be a pre-event coach, and Gabriella Rowe, CEO of Station Houston, will be an on-site coach.

3 Houston innovators to know this week

Who's Who

This week starts in one year and ends in the next, and InnovationMap has three inspiring entrepreneurs to lead you into 2019. All three are behind Houston startups that are planning for big growth in the upcoming year. So, read their stories and get familiar with their names and faces — they aren't going anywhere.

Ben Johnson, founder and CEO of Apartment Butler

Ben Johnson has his own master plan. He'd work as an oil and gas banker for a bit, establish himself, get his MBA, and then, when he was in his 40s, would start his own company. He wasn't wrong about his future as an entrepreneur, but he was off by the timeline.

Johnson started Apartment Butler a few years ago when he saw how apartment communities had the potential to provide streamlined access to resident elected services — such as cleaning or pet care. At the same time, apartment communities across the U.S. were looking to beef up their amenities. Now, Apartment Butler is expanding to its third and fourth markets early next year and is looking to provide more services to its users.

Scott Parazynski, CEO of Fluidity Technologies

There are Renaissance men and then there's Scott Parazynski. He's has spent 57 days in space, trained as a trauma surgeon, and climbed Mount Everest as a team physician for the Discovery Channel. His latest conquest is designing a drone controller based on movement in space. The device, called the FT Aviator, allows for one-handed piloting of drones and has the potential to affect the way unmanned vehicles are piloted across industries. As the CEO of Fluidity Technologies, he has big plans for what one-handed drone operation can do.

David Grimes, CEO and co-founder of Snap Diligence

Hell hath no fury like a businessman scorned. When a business partner ended up being a shady miscreant, David Grimes realized there wasn't a digital vetting tool where you can evaluate a potential associate. After thinking on the idea for a while, Grimes found a co-founder and a way to create an algorithm that can take public information and run it against a person. The company he created is called Snap Diligence.

Now, the tool has morphed into something else that's been unexpectedly in demand. Snap Diligence can find business connections through your already-established network of associates. It's this new feature the company is looking to expand in 2019.

Ben Johnson thought consolidating resident services for household chores — like doing the dishes and walking the dog — could be done more efficiently. So, he created Houston-based Apartment Butler in 2016 to do just that.

"I started thinking a lot about apartment industry," Johnson, who is the founder and CEO, says. "I just saw the industry as a whole is one that hadn't been really disrupted yet — the technology was dated." Read the full story here.

Houston-based company's device is revolutionizing drone technology across industries

Unmanned with one hand

It's not enough that Scott Parazynski has spent 57 days, 15 hours and 34 minutes in space. Nor is the fact that he's trained as a trauma surgeon. Not even climbing Mount Everest as a team physician for the Discovery Channel could satisfy one of Earth's most talent-blessed residents. Now Parazynski is on course to change multiple industries with his latest invention.

Not surprisingly, the member of the US Astronaut Hall of Fame based his design on movement in space. He wanted to approximate the movement of simultaneously shifting from one place to another, but also changing the body's orientation. In zero gravity, it takes precision and planning, Parazynski says, to do that in the most efficient way possible.

As a member of the Houston Methodist Research Institute, his goal was to create a joystick-like device "that would revolutionize surgical robotics." That is still a target for the technology, but with his own Houston-based company, Fluidity Technologies, Parazynski is first releasing the device as a drone controller known as FT Aviator.

"Mostly because it's an enormously growing marketplace and the barriers are a lot less," he admits.

That's not to say Parazynski is anything less than a world-class expert on the subject of flight.

"I've flown aircraft and spacecraft," says Parazynski. "But none allowed for the precision of motion I was looking for. None prevented unintended motion."

Lifelong passion
He himself has had toy drones for as long as they've been available and purchased his first "serious drones" three or four years ago, around the same time he conceived of FT Aviator.

When he started to research other drone controllers, he realized that most current models aren't too different from relics from the 1930s on display at the Smithsonian.

"There has been zero innovation in flight control," he says.

As opposed to the two-handed controllers that recall 1990s video game systems, FT Aviator only requires the attention of the pilot's dominant hand. This is especially useful to those using drone cameras. Instead of complex machinations that often require multiple launches, the user can simply make adjustments to the camera with his or her other hand.

"It does this incredibly intuitive motion with a drone or computer game or virtual augmented reality," Parazynski says, listing other potential uses for the technology.

It's FT Aviator's natural movement that will one day make Fluidity's core technology a groundbreaker in surgical robotics. Since the da Vinci surgical robot's 2000 FDA approval, the machine has created controversy. In the hands of a well-trained surgeon, it substantially reduces healing time. But there is no approval process for doctors to use it, so disasters in the hands of untrained practitioners have made the news.

By using the simpler mechanism of Parazynski's technology, the learning curve for robotic surgery is far less steep.

"What we want to do is make it so someone with less training can enjoy the same outcomes," Parazynski explains.

Cross-industry innovation
Ideally, one day a doctor in Houston will be able to operate remotely on a patient across the globe. Thanks to the device's tactile feedback, it's a realistic goal.

But Parazynski foresees "dozens of applications" for his invention, which will begin shipping in February. Sandia National Laboratories in New Mexico has already engaged Fluidity, just one on a list of about 50 businesses and government institutions interested to work with the company when it comes onto the marketplace.

"But any good startup will tell you it's about focus," the entrepreneur admits.

That means that for now, he and his team have his eye specifically on controlling drones. Within two weeks of launching a Kickstarter this fall for the business, Fluidity doubled its goal. The FT Aviator has been named a 2019 Innovation Award Honoree at the 2019 Consumer Electronics Show. But Parazynski says he owes much of his success to Houston, his home of a quarter century.

Fluidity is based out of a WeWork coworking space.

"I think it's a really exciting place to have a tech startup" Parazynski says. "It's not yet to the scale of Silicon Valley or even Austin but certainly the innovation that's taking place here warrants a major tech hub."

And thanks to Parazynski's work, that day may be coming sooner rather than later.

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

  • 1. Memphis, Tennessee
  • 2. Houston, Texas
  • 3. St. Louis, Missouri
  • 4. San Francisco, California
  • 5. Kansas City, Missouri
  • 6. Albuquerque, New Mexico
  • 7. Oakland, California
  • 8. Nashville, Tennessee
  • 9. Philadelphia, Pennsylvania
  • 10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

  • Fort Worth ranked No. 22
  • Austin ranked No. 26
  • San Antonio ranked No. 54
  • Dallas ranked No. 73
