Last year, Optellum, based in the United Kingdom, opened its United States headquarters in Houston, and shortly after Jason Pesterfield joined to lead the team. On a recent Houston Innovators Podcast episode, Pesterfield explained it's just the start of the company's presence in Houston.

"We're really at the beginning of it," he says. "This is the epicenter of medicine within the United States. There's no bigger or better place for health care than Houston. It's great to be a part of that and to have access to those facilities and those world class physicians and care teams." Read more.

The Houston Energy Transition Initiative and the Center for Houston’s Future have teamed up with the Mission Possible Partnership to lead the city of Houston through the accelerated development of a regional clean industrial hub geared at decarbonization of the industrial sector, including petrochemicals, cement plants, heavy transportation, and more.

The two-year project is focused on development and deployment of clean energy projects — such as "low-carbon hydrogen, carbon capture, use and storage, electrification of industrial processes, and the production and use of low carbon fuels," according to a press release.

“There is no geography in the world better positioned to support the transition to and integration of abundant, low-carbon energy solutions than Houston," says Jane Stricker, executive director and senior vice president of HETI, in the release. "As the Energy Transition Capital of the World, Houston is leveraging its energy leadership to accelerate global solutions for a low-carbon future. This partnership with MPP is a critical component in the region’s efforts to develop and deploy technologies, policies and strategies for broad decarbonization." Read more.

In a guest column for InnovationMap, Michael Lee, CEO of Octopus Energy, called for tech innovators to change lanes to focus on the climatetech industry.

"We used to say, 'every company will become a tech company.' We’re now moving towards a world where 'every company is a climate company,'" Lee writes. "And that is creating opportunities throughout the economy for people to contribute their skills and support their families while building something that actually matters." Read more.

Houston innovator gears up for commercialization for AI-driven lung cancer diagnostic tool

HOUSTON INNOVATORS PODCAST EPISODE 164

When a United Kingdom-based, artificial intelligence-driven lung cancer detection tool opened its United States headquarters in Houston, the company tasked Jason Pesterfield with the role of CEO to oversee international expansion and commercialization strategy. Pesterfield, who's based out of the Texas Medical Center's Innovation Institute, is familiar with the job he's been hired to do — that's because he's done it before.

After spending almost two decades at medical technology company, Stryker, Pesterfield joined St. Louis-based Veran Medical Technologies, a company also focused on lung cancer detection, and grew the business over 8 years years to a $30 million-plus annual revenue company before it was acquired by Olympus Corp. in 2020.

After assisting with the transition, he was approached by U.K.-based Optellum's Founder Timor Kadir about taking the reins of Optellum last year to again help scale the early stage digital health company.

"I'm not a computer scientist or an algorithm guy, but I do have experience in commercialization, leading teams, building culture, acquire great talent, working with my team to build a great strategy, and working with investors to make sure we're in a good financial position," Pesterfield says on the Houston Innovators Podcast.

Optellum was founded in 2016, and first entered the Houston market by way of the TMC's accelerator program and its BioBridge with the U.K. The company's technology is an AI platform that helps practitioners diagnose and treat early-stage lung cancer. The software uses natural language processing to scan medical reports of nodules in the lungs to give health care providers more information on cancer diagnostics — an analysis that takes just seconds.

"It's like having a hundred thousand sets of eyes looking over a physician's shoulder," Pesterfield says.

In September, the company raised a $14 million series A round of funding, and Pesterfield explains how that funding is being deployed to focus on growing teams within sales, B2B support, and its research and development pipeline.

He explains on the show that Optellum is just getting started with its relationship within the Houston innovation ecosystem. Pesterfield says Optellum is even on the path to securing its first Houston-based customer.

"We're really at the beginning of it," he says. "This is the epicenter of medicine within the United States. There's no bigger or better place for health care than Houston. It's great to be a part of that and to have access to those facilities and those world class physicians and care teams."

Pesterfield share more on Optellum's future on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Optellum, a medical software startup based in the United Kingdom and has its United States HQ in Houston, has appointed Jason Pesterfield as CEO to lead growth in the U.S. clinical market. Optellum AI-based software enhances early lung cancer diagnosis and therapy with its medical device software platform, Virtual Nodule Clinic.

Optellum was founded by Václav Potěšil, Lyndsey Pickup, Timor Kadir, Professor Sir Mike Brady, and Jérôme Declerck.

"It took us almost a year to find the right successor who shares our vision and has the right expertise to take Optellum on to the next stage of growth," says Potěšil in a news release. "I am really excited to work with Jason, to make Optellum's platform available to every clinician in the USA and around the world, and to help them diagnose their lung cancer patients as early as possible. With Jason on board, I can focus on advancing Optellum's vision to transform early lung cancer therapy through partnerships that harness the power of AI software combined with molecular diagnostics, robotics and interventional devices, and drugs."

Fresh off its $98 million series B, Cart.com has named its first chief revenue officer. Randy Ray is tasked with driving sales growth across the company. He has over 15 years of sales and operations experience and was previously senior vice president at supply-chain solution provider High Jump.

"I've worked with the world's biggest retail and SaaS brands, and I've seen the need for a unified Ecommerce-as-a-Service hub to create operational efficiencies and unlock scalable success," Ray says in a press release. "I'm a firm believer in the Cart.com mission to drive success for online brands, and I'm looking forward to tripling our sales organization and building out a world-class revenue infrastructure as we take the company global over the next 6 to 9 months."

Houston company partners on AI-powered medical support for space missions

AI in space

Houston-based Aexa Aerospace has partnered with SpacePort Australia (SPA) to build medical AI solutions for space crews.

Known as The Hamilton Project, the collaboration aims to complete the training and refinement of a “deductive medical AI model” designed to aid and treat astronauts and space travellers. With limited to no real-time access to doctors on Earth during space missions, the project's goal is to create an AI model that would serve as a medical resource.

“‘The Hamilton Project’ is a sophisticated AI model, integrating academic and clinical knowledge in a unique way,” Aexa founder and CEO Feranando De La Peña Llaca said in a news release. “It is paving the way for future autonomous attending.”

The project is named after NASA flight surgeon Dr. Douglas Hamilton, who participated in 50 missions.

SPA, an independent research organization, will bring its practical medical knowledge and clinical experience to The Hamilton Project, which builds on Australia’s rural and remote medical training programs. SPA founder Dr. Gabrielle Caswell brings 20 years of remote medicine experience that SPA believes will help address the issues that could be encountered in space.

“Rural general practitioners in Australia practice ‘pre-cradle to grave’ medicine, including areas considered sub-specialities in most western countries: OBYN, paediatrics, trauma management, anaesthetics, general surgery, mental health and geriatrics,” Caswell added in the release. “This broad clinical skill set encompasses all stages and phases of human life. And importantly practitioners are also trained in the management of severe trauma. "It is anticipated that doctors and medical staff will become embedded into missions, and all these skills will be required over time, to create successful space economic zones.”

Aexa Aerospace’s previous work includes developing holographic medical devices that have been trialled on the International Space Station. Read more here.

Houston residents rank economy as biggest problem, new Kinder survey shows

by the numbers

The region’s economy tops the list of concerns of Houston-area residents surveyed by Rice University’s Kinder Institute for Urban Research.

Respondents in the Kinder Houston Area Survey, which questioned nearly 9,000 residents of Harris, Fort Bend and Montgomery counties, cite the regional economy as the area’s “biggest problem.”

Shrinking confidence in job opportunities and growing household financial pressures fueled the grim economic outlook:

  • The share of residents rating job prospects as “good” or “excellent” fell by more than 25 percentage points, the sharpest single-year decline since the 1980s.
  • Seventy-nine percent of those earning less than $25,000 said they’d be unable to cover an unplanned $400 expense. That was up from 72 percent last year. In the $50,000-to-$99,999 category, the figure was 39 percent, up from 30 percent last year.
  • More than 20 percent of residents said their financial status was worse than it was 12 months earlier.

“These challenges were particularly notable among lower- and middle-earning households,” according to a report about the survey.

Dan Potter, co-director of the institute’s Houston Population Research Center, says the annual survey “provides community leaders and the public with a map of where we’ve been on key issues, where we are now, and what’s of looming importance. It allows everyone to work together toward a better future for our city and our region.”

Houston-based Oxy officially announces CEO transition, names successor

Team Transition

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
