Several organizations — from tech startups to a nonprofit — have moved into the Ion recently to either relocate or expand their presence in Houston.

The Ion District announced new tenants today, bringing the total space leased to 86 percent, according to a news release. The recent additions to the Ion include:

  • Carbon Clean announced its new United States HQ last month. The startup’s technology has captured nearly two million tons of carbon dioxide at almost 50 sites around the world.
  • Cognite is a Norwegian software company for asset-heavy industries that turns industrial data into customer value.
  • OpenStax, a Houston-based nonprofit, is publishing openly licensed college textbooks that are free online and low cost in print.
  • Synopic is a California-based startup that's building next-gen depth-enabled cameras to improve visualization and decision making during medical procedures.
  • Houston-based Motif Neurotech, a medical equipment manufacturing startup, is working to develop minimally invasive electronic solutions for mental health.
  • RedSwan CRE, founded in Houston, is a crowdfunding-style investment platform and marketplace of tokenized commercial real estate.
  • Nauticus Robotics, a marine robotics hardtech and software company, recently went public.
  • Rice University’s Office of Innovation and its Nexus Lab, which is under construction and designed for prototyping and scaling-up technologies, is increasing its presence in the Ion.
  • Also noteworthy is the expanded office of Ara Partners, which first moved into the Ion last year. The Houston-based, global private equity firm is focused on investing in carbon decentralization technology.
  • Dallas-headquartered flexible workspace provider Common Desk announced that it would expand its space by nearly 50 percent at the Ion last December.

“Welcoming this amazing lineup of new tenants, across the breadth of sectors they represent, demonstrates that the Ion is the place to be and do business in Houston,” says Jan E. Odegard, executive director of the Ion, in the news release. “By continuing to fill our space with new innovators across all these different offerings, from all around the globe, we’ve become the home for collisions that will create solutions to the biggest problems facing our world today.

"We pride ourselves on advancing the diverse knowledge, teams, technologies, and products that will propel our world forward. Our inspiring new tenants will do just that,” he continues.

The Ion's grand opening took place just about a year ago, and existing tenants include Chevron, Microsoft, (Schlumberger) SLB Innovation Factori, Houston Methodist. The growing Ion District is home to more than 300 businesses, including corporates, small businesses, startups, and restaurants.

“The Ion continues to see leasing demand from companies that understand the value of a creative and active work environment,” says Bryson Grover, investment manager of real estate development at Rice Management Co. “Companies are choosing Ion District because it offers more than just a solution for space needs. Workers are given the opportunity to experience a sense of community that brings together like-minded individuals and those with different perspectives.”

3 alumni-founded startups claim cash prizes at Rice University pitch competition

winner, winner

Three startups founded by Rice University graduates have won investment prizes at an annual pitch competition.

The annual H. Albert Napier Rice Launch Challenge, or NRLC, welcomed a panel of judges to hear from six alumni-founded startups in the finals last week. The prizes on the line totaled $65,000 in equity-free funding. The event, which is separate from the student version of the competition, is hosted by Rice’s Liu Idea Lab for Innovation and Entrepreneurship.

The big winner of the 2022 competition was Rhythio Medical, a preventative heart arrhythmias treatment startup. The company won first place, which included $30,000 in equity-free funding, as well as the Audience Choice Award that came with $1,500.

Taking second place, Synopic, which facilitates faster and more accurate surgical procedures through improved endoscopic vision technology, won $20,000 in equity-free funding. Lastly, Green Room, a platform that streamlines taxes and payments for touring artists, clinched third place and $15,000.

The event, named for Rice professor emeritus and entrepreneurship program founder H. Albert Napier, was sponsored by Mercury Fund, T-Minus Solutions and Chevron Technology Ventures. This year's finalists were selected by judges made up of Rice alumni. Three judges — Danielle Conkling, director at Silicon Valley Bank, Paul Manwell, senior director at Google, and Joanna Nathan, manager of new ventures at Johnson & Johnson — listened to and evaluated each company's five-minute pitch and followed up with questions.

Rhythio Medical was founded by CEO Kunal Shah, class of 2022, and Savannah Esteve, who also serves as head of product. The technology includes a surgically injected wire that makes an irregular heart work like a healthy one. It works alongside a traditional implantable cardioverter defibrillator, however, the wire but works to prevent arrhythmias, while ICDs treat arrhythmias with a painful shock to the patient’s heart. The company lists the Texas Heart Institute and the University of Texas at Austin as its research partners.

2 Houston suburbs rank among 10 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.
