The Ion Smart and Resilient Cities Accelerator has named the five companies participating in its latest cohort, which starts next week.

Launched in 2019, the programing for the accelerator and its member companies focus on addressing the needs and challenges the city of Houston and other major metros are facing — including climate change. The five selected companies will start the 12-week program next week with a goal of securing a pilot with the city.

"We're thrilled to kick-off Cohort 3," says Christine Galib, senior director of programs at The Ion, in a news release. "The ISRCA remains a core asset in The Ion's Programs portfolio, since it enables recurring collisions, connections, and collaborations among startups, stakeholders, and subject-matter experts."

The selected startups are:

  • Phase Filter/Kinetic Synergies: The university-born startup has created an automatically changing air filter that works with existing HVAC systems to lower cost and energy use as well as eliminate the annoying chore.
  • Frakktal: In an effort to create a circular economy, Frakktal repurposes and reuses discarded polymer materials from the greater Gulf Coast region to also use in the same region.
  • Moonshot Compost: The company collects food waste from Houston residents and businesses via curbside pickup and drop-off while also collects and provides data on each pickup.
  • Teratonix: Using radio frequency (RF) electromagnetic from radio /TV broadcast, cell phone tower, wifi routers, and more, Teratonix provides solutions to generate electricity.
  • Smart Watts:The company taps into smart meter sensors to enable a personalized energy monitoring dashboard that provides users with data to make better energy use decisions.

"The ISRCA Cohort 3 will highlight companies that focus on making sure Houston is here for generations to come," says Courtney Cogdill, program manager for The Accelerator Hub at The Ion, in the release. "By activating the Houston innovation ecosystem and showcasing Houston's talent, Cohort 3 will spotlight Houston as a city committed to sustainability."

The previous cohorts of the program focused on resilience and mobility in Cohort 1 and cleantech for Cohort 2.

"As the world-at-large expands their mobility with social distancing restrictions lifted, it's important cities and businesses review their sustainability practices and carbon footprint and continue to improve upon the progress that's been made," says Jan E. Odegard, interim executive director of The Ion, in the release. "The Ion is excited to empower entrepreneurs who will play a critical role in improving sustainability. With Houston and our diverse and innovative industries as a backdrop, The Ion is prepared to address the challenges sustainability will face in a post COVID-19 world."

The program will be housed in The Ion, a 266,000-square-foot mixed-use structure, which is expected to open within the next few months, along with the organization's other accelerator programs.

Former NASA astronaut, official joins Venus Aerospace board

astronaut appointment

Retired Air Force colonel and former NASA astronaut Pamela Melroy, who previously served as deputy administrator of NASA, recently joined the board of directors at Houston-based Venus Aerospace.

Venus Aerospace, a startup founded in 2020, develops rocket engine technology, including rotating rocket detonation engines for hypersonic flights. These engines promise higher power, greater fuel efficiency and lower emissions than conventional rocket engines or jet engines, according to the Interesting Engineering website. The global rocket propulsion market is expected to grow from $9.5 billion in 2025 to $29.9 billion by 2034, according to a forecast by ResearchAndMarkets.com.

“Advanced rocket propulsion has been of interest to me for over a decade, and Venus Aerospace’s recent achievements in demonstrating the stability of rotating detonation rocket engines represent a significant development,” says Melroy, who left NASA earlier this year and is now a self-employed consultant living in Arlington, Virginia.

Melroy, a member of the United States Astronaut Hall of Fame, has built an illustrious career in the aerospace sector. Aside from being a NASA official, she was:

  • One of only two female astronauts to command a space shuttle mission
  • Deputy program manager of Orion space exploration initiatives at aerospace and defense contractor Lockheed Martin
  • Senior technical adviser and director of field operations for the Federal Aviation Administration’s Office of Commercial Space Transportation, where she came up with the first safety guidelines for commercial human spaceflight
  • Deputy director of the Tactical Technology Office at the Defense Advanced Research Projects Agency (DARPA).
  • An adviser for the establishment of the Australian Space Agency

Venus Aerospace said in a news release that as a leader at three federal agencies, “Melroy shaped America’s strategy in space, accelerated commercial space partnerships, and deepened space exploration.”

Sassie Duggleby, co-founder and CEO of Venus Aerospace, called Melroy “a preeminent leader in the world of aerospace.”

In May, Venus Aerospace completed the inaugural test flight of its rotating detonation rocket engine. The startup, whose headquarters is at the Houston Spaceport, says it’s the only company in the world that has manufactured a flight-proven, high-thrust rotating detonation rocket engine.

On the horizon for Venus Aerospace is production of Stargazer M4, a high-speed aircraft capable of two-hour global travel.

Venus Aerospace’s investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. The startup also gets support from the Air Force Research Laboratory (AFWERX), the Air Force, NASA and DARPA.

Jordan Blashek, co-founder and managing partner of America’s Frontier Fund, which backs startups creating breakthrough technologies, said his firm’s investment in Venus Aerospace “underscores our focus on supporting American companies that are revolutionizing industries of the future.”

“With recent hypersonic advancements from China and Russia, safeguarding American innovation and securing our industrial base has never been more urgent,” Blashek added. “Venus Aerospace is poised to redefine hypersonic flight and ensure America’s continued leadership in aerospace innovation.”

Since its founding, Venus Aerospace has raised $78.3 million in investments, according to PitchBook data.
