There are several ways for a Houston startup to make an exit — it could IPO, receive massive private equity funding, or even get acquired. It wasn't always in the plan for Robert Kester to have his startup take the acquisition route, but he saw a huge opportunity to get the technology he had worked on for a decade into the field — and he took it.

Kester co-founded Rebellion Photonics in 2010. A doctoral candidate at Rice University at the time, Kester had an idea for scaling a sensor technology that can detect chemicals. The developed device could be used to automate the process and improve safety on oil and gas sites.

"When we first got going, it was an idea on a napkin. We had no idea if it could work or not," Kester says on this week's episode of the Houston Innovators Podcast. "So getting those first pilots from companies like BP — some of these major companies believing in us and deploying the technology. We grew it to a point where we'd shown value, and we were scaling the solution."

Kester says he initially saw this application benefitting onsite safety, but it quickly evolved into being a key took to promoting sustainability in a world where climate change is increasingly on everyone's mind. The company started considering a way to get its technology to scale — and fast. In 2019, Rebellion exited in an acquisition by Honeywell.

"For us it just made sense that we could team up with Honeywell and figure out how we could scale this thing globally and quickly, so that we could help be a solution for climate change," Kester continues.

Now, as president and general manager at Honeywell Rebellion, Kester still oversees his technology and, with the support of Honeywell, is able to see it be deployed at a quick pace.

Amid the pandemic, he was even able to make a pivot with his technology. Recognizing the importance of temperature reading as an early indicator of COVID-19, Kester and his team worked to develop ThermoRebellion, a temperature scanning technology that was implemented in airports — like JFK and Boston's Logan Airport — to screen travelers.

"I think the latest statistic I heard is that we've scanned over a million passengers coming in and out of the country," Kester says. "For me, I get a lot of satisfaction out of the fact that we're working on important issues in trying to keep the country safe."

Kester shares more about what he's focused on at Honeywell Rebellion on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Tech giant warms up to temperature monitoring system created by Houston startup

temp tech

A Houston startup's temperature monitoring system originally developed for oil and gas facilities is being used to help companies safely get their employees back into work.

The ThermoRebellion temperature software uses technology from Houston-based Rebellion Photonics, which Honeywell acquired in December of last year. The technology uses infrared imaging technology and artificial intelligence to quickly conduct non-invasive screenings of people before they enter offices, banks, airports, as businesses begin to reopen.

Robert Kester, Rebellion Photonics founder and Honeywell president and general manager, says the ongoing health crisis called for a reimagining of the AI-driven oil and gas technology, which is used to quickly detect leaks by using a real-time monitoring platform that provides automated notifications.

"The key component is our software powered by artificial intelligence," Kester tells InnovationMap. "Our imaging systems leverage a decade of experience in the most advanced imaging technologies for gas leak detection, fire detection, and intrusion monitoring applications. The system features uncooled high-resolution FPA infrared sensors allowing for each pixel to be assessed for temperature."

As states begin to lift stay-at-home orders, a return to a new normal is expected, as people begin to go back to the workplace and have to spend time in commercial buildings surrounded by others. In Houston's Memorial Hermann Hospital, temperature scanners by Austin-based Athena Security have already been installed, minimizing contact and reducing foot traffic congestion in entrances.

"Experts believe temperature checks can become more common in public spaces," says Kester. "Our system works allows for social distancing as people don't have to queue closely. Imagine an airport, for example, it wouldn't be feasible to have passengers wait in additional long lines for temperature screening."

The ThermoRebellion system can scan individuals in groups for effective screening at a wide range of sites and venues, instantly providing temperature results in an non-invasive manner, to keep employees and customers safe from introducing and spreading coronavirus.

"It's important for people to get back to work safely, whether that's an office building or a factory, or taking a flight to meet a customer," says Kester.

Honeywell is moving the technology to its piloting phase, racing against the clock to meet the demand as businesses open for business. The system, according to Kester, is intuitive and easy to use, implementing audible and visual alarms to alert if a person has elevated body temperature. Plus, it can also be easily deployed to different access points.

The fast-tracked product couldn't have been done without the team of designers and engineers who quickly pivoted from gas imaging to body temperature solutions. The team is already recruiting potential users who are interested in implementing the system in their facilities.

By Kester's and his team's estimates, the ThermoRebllion system will be ready to deploy as early as June.

"It's going to be difficult for people to go back to busy locations without knowing that companies are taking proactive steps to protect its patrons or employees," says Kester. "We're excited to be part of the set of solutions that can help improve safety."

Texas universities develop innovative open-source platform for cell analysis

picture this

What do labs do when faced with large amounts of imaging data? Powerful cloud computing systems have long been the answer to that question, but a new riposte comes from SPACe.

That’s the name of a new open-source image analysis platform designed by researchers at Baylor College of Medicine, Texas A&M University and the University of Houston.

SPACe, or Swift Phenotypic Analysis of Cells, was created to be used on standard computers that even small labs can access, meaning cellular analysis using images produced through cell painting has a lower barrier to entry than ever before.

“The pharmaceutical industry has been accustomed to simplifying complex data into single metrics. This platform allows us to shift away from that approach and instead capture the full diversity of cellular responses, providing richer, more informative data that can reveal new avenues for drug development,” Michael Mancini, professor of molecular and cellular biology and director of the Gulf Coast Consortium Center for Advanced Microscopy and Image Informatics co-located at Baylor College of Medicine and TAMU Institute for Bioscience and Technology.

SPACe is not only accessible because of its less substantial computational needs. Because the platform is open-source, it’s available to anyone who needs it. And it can be used by academic and pharmaceutical researchers alike.

“The platform allows for the identification of non-toxic effects of drugs, such as alterations in cell shape or effects on specific organelles, which are often overlooked by traditional assays that focus largely on cell viability,” says Fabio Stossi, currently a senior scientist with St. Jude Children’s Research Hospital, the lead author who was at Baylor during the development of SPACe.

The platform is a better means than ever of analyzing thousands of individual cells through automated imaging platforms, thereby better capturing the variability of biological processes. Through that, SPACe allows scientists an enhanced understanding of the interactions between drugs and cells, and does it on standard computers, translating to scientists performing large-scale drug screenings with greater ease.

"This tool could be a game-changer in how we understand cellular biology and discover new drugs. By capturing the full complexity of cellular responses, we are opening new doors for drug discovery that go beyond toxicity,” says Stossi.

And the fact that it’s open-source allows scientists to access SPACe for free right now. Researchers interested in using the platform can access it through Github at github.com/dlabate/SPACe. This early version could already make waves in research, but the team also plans to continually improve their product with the help of collaborations with other institutions.

Texas ranks among the 5 best states to start a business in 2025

Best for Biz

As one of the largest states in the U.S., it's no surprise Texas is big on business and entrepreneurship. Now the state is earning new praise among WalletHub's 2025 list of "Best & Worst States to Start a Business."

The Lone Star State claimed the No. 4 spot in the report's rankings, proving that Texas is in a much better business shape than it was last year when it earned No. 8 in WalletHub's annual report.

The study compared all 50 states across 25 metrics to determine the best places to start, grow, and find success with a new business. Factors that were considered include the number of startups per capita, job growth rates, financing accessibility measures, labor costs and corporate tax rates.

The three states to outperform Texas in the 2025 report are Florida (No. 1), Georgia (No. 2), and Utah (No. 3). Idaho rounded out the top five.

Across the study's three main categories, Texas performed the best in the "business environment" category, earning No. 1 nationally. This section compares the states based on five-year business survival rates, average business revenues growth and more.

Texas ranked No. 12 in the nationwide comparison of "access to resources" – which covers working age population growth, venture investment amounts per capita and other means – and earned a fair No. 34 in the report's "business costs" ranking.

But Texas can still do better with its business friendliness to reclaim a top-three overall ranking, which the state last earned in 2023.

WalletHub analyst Chip Lupo said in the report that it is imperative for potential new business owners to establish their enterprise in a place that can maximize their ability to succeed.

"Around half of all new businesses don’t survive five years, so the idea of becoming a business owner can be daunting, especially with the current high cost of living," Lupo said. "The best states have low corporate tax rates, strong economies, an abundance of reliable workers, easy access to financing and affordable real estate. On top of that, you’ll need to make sure you start in a place with an engaged customer base, if you’re operating locally."

Houston has also proven to be at the top of the destination list for entrepreneurs who are looking for their next venture.

The top 10 best states to start a new business in 2025 are:

  • No. 1 – Florida
  • No. 2 – Georgia
  • No. 3 – Utah
  • No. 4 – Texas
  • No. 5 – Idaho
  • No. 6 – Oklahoma
  • No. 7 – Nevada
  • No. 8 – Colorado
  • No. 9 – Arizona
  • No. 10 – Kentucky
