Switching from a gas-powered car to an electric one can be a big change, but a Houston-based company has made things a lot easier for its customers.

Octopus Electric Vehicles US, a spinout of United Kingdom-based retail energy provider Octopus Energy, matches its users with their perfect EV lease and sets them up with smart electricity technology for at-home charging.

"We do a couple of really unique things that are not only first of its kind but really innovative," Octopus EV's US Co-Lead Chris George says on the Houston Innovators Podcast, pointing out specifically Octopus Energy's Intelligent Octopus, a smart feature for customers that automates energy usage to lower cost.

"We launched an Intelligent Octopus for EVs service. Instead of operating in a very narrow window — overnight — it operates dynamically," he continues. Read more.

The James P. Allison Institute at The University of Texas MD Anderson Cancer Center scored a $5 million gift at its second annual symposium.

On behalf of Mayor John Whitmire, Oct. 10, 2024 was named “James P. Allison Institute Day,” and it was also the day that the TMC3 Collaborative Building in the Texas Medical Center’s Helix Park greeted 900 attendees for the scientific symposium, entitled “Immunotherapy in Space and Time: The Tumor Microenvironment.”

“Spatial biology is a rapidly expanding field that offers tremendous new insights into immunobiology that were not possible just a few short years ago. Understanding how immune cells interact with their neighbors and with tumor cells in space and time will enable us to bring forward new strategies to improve immunotherapy outcomes,” says James P. Allison. “We are proud to host this annual symposium to advance the field, and we are extremely grateful for the support of the Wintermann Foundation to make new breakthroughs possible.” Read more.

From advice to observations, these five quotes overheard at SXSW proves Houston had some great spokespeople at the 2019 SXSW Interactive festival. Photos courtesy

Overheard: 5 powerful quotes from Houstonians speaking at SXSW

Eavesdropping in Austin

Houston had no shortage of representatives at the 2019 SXSW Interactive festival, which took place March 8 to 12 in Austin. Several sat on panels, lead mixers, or even starred in a movie for the film track of the conference.

I had the pleasure of sitting in on a great deal of these events featuring the best and the brightest of Houston's innovation stars, but I realize most did not. To catch you up and rid you of your fear of missing out, check out these five overheard quotes from the fest.

"I think it's so important to find your focus and know what to say no to, because you can't do it all. Elizabeth [Gore] and I have a monthly 'meeting of no' where we literally check off things off our plate that we need to stop doing because we just don't have enough time. It's probably one of our most valuable hours."

— Carolyn Rodz, co-founded Alice with Elizabeth Gore. Alice co-hosted a series of panels at the Bumble Hive. She was asked, during the investment-focused panel, about focusing on B-to-B vs. B-to-C as a startup. Alice and Bumble just recently announced a partnership.

"We're trying to awaken the sleeping giant — a really huge city with lots of money, trying to infiltrate and activate huge family offices and rally people behind the goal of building a vibrant startup community. We've got a long way to go in terms of attracting VC talent — we're still behind Austin and Dallas."

— Lawson Gow, founder and CEO of The Cannon, at the Austinpreneur podcast recording of "The Texas Startup Manifesto" episode. He was asked about what he's been trying to accomplish at The Cannon. Gow is the son of InnovationMap's parent company's CEO.

"We've got all the basic tools, and we know what the main issues are. There's still a lot to do, but we need to be smart and do fact-based and mechanism-based combinations."

— James Allison, chair of Immunology and executive director of the Immunotherapy Platform at MD Anderson Cancer Center. At his panel, "Making the Fight Against Cancer Even More Personal," he was asked about the current status of immunotherapy research.

“Have very specific questions. I hate the ‘can I pick your brain’ request. If you want advice on something, ask me that specifically. And, show up at everything. … It’s not about what network you have, but how many networks you can get into.”

— Grace Rodriguez, CEO and executive director of Impact Hub Houston. On the "Equitable Growth Ecosystems for Entrepreneurs" panel, she was asked about how an entrepreneur might try to grow their network and mentorship.

"Houston is an incredibly industrial town. We have more Fortune 500 companies here than anywhere other than New York — most of them in the world of the dirty and dangerous. We don't have a lot of scooter companies."

— Gabriella Rowe, CEO of Station Houston. She was asked while on her panel, "Startup Funding: From Apprenticeships to Professions," about bootstrapping as a startup. Read more about this discussion here.

Film about Nobel Prize-winning Houston scientist premieres at SXSW

Now showing

For most of his career, James Allison has been a cancer research wildcatter fighting an oftentimes lonely battle for the advancement of immunotherapy. The medical community has historically been skeptical of the science, but nonetheless Allison dedicated his life to developing a better treatment to the disease that has claimed so many lives — including his mother's.

Last year, Allison, the chair of Immunology and executive director of the Immunotherapy Platform at MD Anderson, won the 2018 Nobel Prize in medicine, and Breakthrough, a film about Allison's progression from early researcher to Nobel Prize recipient, premiered on March 9 at the 2019 SXSW Interactive festival.

But despite the Nobel Prize and the new film both validating the science to the public, Allison says there's a lot more work to be done in immunotherapy. Allison, his colleague, Padmanee Sharma, and the filmmaker for Breakthrough, Bill Haney, hosted a discussion at SXSW about the future of immunotherapy.

"It's a time of considerable optimism — and we're just at the beginning," says Allison.

The film focuses on the man behind the science — a 70-year-old, harmonica-playing researcher from small-town Alice, Texas. It's both an ode to Allison's career and a thought-provoking take on all the work left to be done in the industry.

Immunotherapy is the process of targeting one's immune system's T-cells, infection-fighting white blood cells, to attack cancer cells. Sharma, a fellow MD Anderson oncology expert and clinician, says their work has received clinical approvals for treating Melanoma, kidney cancer, lung cancer, and bladder cancer. The scientists are now focused on expanding that treatment to other cancer types and building upon the established platform they've created, while also making sure nothing comes in the way of the facts of the science.

"It really requires that we dedicate ourselves to the basic science, understanding it and educating people about it, so we don't allow the facts and science get muddied by things that are political or nonfactual," Sharma says.

In a lot of ways, this is what Breakthrough has been able to do — communicate the facts on a platform where anyone can understand the science.

"We have a revolution on our hands, and thankfully we have people like Bill who can really tell the story well, because maybe as a scientist and a clinician, we're not always equally talented on telling the story to laypeople," Sharma says.

Moving forward, Allison says he's focused on finding out why the treatment fails in some instances, and he's determined to progress immunotherapy's success rate from the 20 to 40 percent rate he says he sees it at now to 100 percent.

"We've got all the basic tools, and we know what the main issues are," Allison says. "There's still a lot to do, but we need to be smart and do fact-based and mechanism-based combinations."

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
