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.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
