The Ion in Midtown has some new tenants taking up residence in its 90 percent-leased building.

Occidental Petroleum Corporation, Fathom Fund, and Activate are the latest additions to the Ion, according to a news release from Rice University and the Rice Real Estate Company, which own and operate the 16-acre Ion District where the Ion is located. With the additions, the building has just 10 percent left up for grabs.

“As the Ion continues to attract leading companies and organizations across industries, it’s clear that our vision of creating a dynamic and collaborative environment for innovation is resonating,” Ken Jett, president of the Rice Real Estate Company and vice president of facilities and capital planning at Rice, says in the release. “We are proud to set the standard for how the workplace can evolve to foster the commercialization and growth of transformative technologies that enhance quality of life in our community and beyond.”

Oxy, which was named a corporate partner of the Ion last year, now has nearly 6,500 square feet on the fourth floor. The build out process is slated to be completed by early 2025.

While Oxy represents the corporate side of innovation, the other two additions have their own roles in the innovation arena. Houston-based Fathom Fund, which launched its $100 million fund earlier this year, is targeting deep-tech venture opportunities and is led by Managing Partners Paul Sheng and Eric Bielke.

Founded in Berkeley, California, Activate, which announced its expansion into Houston in 2023, has officially named its local office in the Ion. The hardtech-focused incubator program recently named its inaugural cohort and opened applications for the 2025 program.

Other recent joiners to the Ion includes Kongsberg Digital, Artemis Energy Partners, CES Renewables, and Eleox.

“The partnerships we’ve forged are vital to shaping the Ion into a vibrant ecosystem for startups, where collaborative innovation is not only driving local economic growth but also positioning Houston as a global leader in the energy transition,” Paul Cherukuri, chief innovation officer at Rice University, says. “With our team leading the programming and activation across the Ion district, we are creating companies that harness cutting-edge technology for the benefit of society—advancing solutions that contribute to social good while addressing the most pressing challenges of our time. This powerful network is redefining Houston’s role in the future of energy, technology, and social impact.”

$100M Houston VC fund launches to back technical founders

show me the money

A new venture capital fund has launched with an initial $100 million mission of supporting founders with innovative critical infrastructure solutions.

Fathom Fund, which is looking to build out a portfolio of advanced computing, material science, climate resilience, and aerospace startups, announced they've launched with an initial close of over $100 million. The fund is founded by longtime investors Managing Partners Paul Sheng and Eric Bielke.

"We believe recent technological advances have accelerated the pace of scientific discovery, increasing the pool of technology companies that can produce venture-scale returns," Sheng says in a news release.

According to the fund, it hopes to bridge the gap for early stage capital for physical innovations and "moonshot" projects.

“What’s lacking in venture is rigorous technical diligence at the early stages and a playbook to scale these innovations at the pace necessary to lead industries," Bielke adds. "With this launch, we are looking forward to supporting founders with some of the most disruptive and novel ideas.”

The founder duo will bring each of the career expertise to their future portfolio companies. Sheng spent decades at McKinsey & Co and was the firm's head of the Global Energy & Materials practice. Bielke is a former director at Temasek’s Emerging Technologies Fund.

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.
