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."
