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."

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Al Danto, Rice University

Al Danto is a senior lecturer in entrepreneurship at Rice University. He mentors undergraduate and graduate students at Rice and through the university's Liu Idea Lab for Innovation and Entrepreneurship (Lillie). He's also involved in the Houston Entrepreneurs Organization and Rice Veterans' Business Battle.

"[Mentoring] is very rewarding and fulfilling," Danto says. "[It] helps to me to pay back full circle over the incredible mentors I have had."

Eric Rubenstein, New Climate Ventures

Eric Rubenstein is managing partner at New Climate Ventures. He mentors startups through the clean energy-focused early-stage VC firm and also through the Breakthrough Energy Fellowship, Activate, Greentown Labs and Yale Ventures. Rubenstein has worked with numerous startups and Innovation Awards finalists, including Solidec, Rheom Materials, Bairitone Health, Pattern Materials and many others.

"Being a mentor is an important part of an innovation ecosystem," Rubenstein says. "Seeing founders succeed is rewarding, particularly if what they are building will meaningfully contribute to society. It is a way to give back that also builds community, as mentorship often involves introducing founders to other mentors, to potential investors and to potential customers. Just like the adage 'it takes a village' is used in reference to raising a child, the same adage applies to building a startup. That’s why we say 'let’s build.' Let’s build is inclusive because we do it together, as a community, even if the founders need to execute on a daily basis to make their vision a reality."

Jeremy Pitts, Activate

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston in 2024. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Mentorship to me is all about selflessly supporting a person," Pitts says. "The person comes first--if you're not supporting the person, then their business needs don't matter. I'm there not to answer questions for people, but to help them gain the confidence and the capability to solve problems on their own. I am successful when my mentees are successful and happy, regardless of what their personal definition of success might look like."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard. He founded Startup Circle Houston and co-hosts Cybersecurity Circle, which both meet regularly at The Ion. He participates in Mercury Fund Day and has also mentored through Impact Hub Houston. He's worked with founders of FlowCare, Unytag, STEAM OnDemand, Lokum and many other early-stage startups.

"I compare being a mentor for startup founders to the Montessori method. ... Mentoring should not involve telling a founder what to do," Alapat says. "I see it as a founder whisperer approach that seeks to challenge the founder to think through their journey through different lenses and go on a journey of self-discovery while discovering the true market pain they are seeking to solve. The cherry on top is that the mentor gains as much as the mentee, so learning is happening for both. Ultimately, the meter of achievement with mentoring is seeing visible progress with the maturity of the founder and the degree of traction for their startup."

Kyle Judah, Rice University's Liu Idea Lab for Innovation & Entrepreneurship

Kyle Judah is the executive director of Lilie, where he mentors pre-seed student startups. He also mentors through organizations like TEX-E, Greentown Labs, Activate and previously with MassChallenge. Some of the startups he's mentored include Helix Earth Technologies, Tierra Climate, Solidec, HexaSpec, SteerBio and many others.

"[Being a mentor] means helping to ensure that the most people possible have the best shot possible at making their company a successful reality," Judah says. "It means, at its root, opening the aperture for what is possible for people, by believing in them before anyone else even understands what their ambitions are. Because belief is the most infectious thing in the world. And before digging into the work in the trenches, most times founders need to kickstart their journey by having someone from the outside believe in them, when there's no real evidence to support that belief. So I guess, mentorship is a pure form of entrepreneurial faith."

Rachel Bickham, Bickham Services Unlimited LLC

Rachel Bickham is CEO of Bickham Services Unlimited, through which she mentors founders across a range of business stages and industries. She founded the organization in 2017. Bickham also mentors through The Affirmed Entrepreneur, a mentorship platform that she also launched. In 2024, she also began mentoring through the Goldman Sachs One Million Black Women: Black in Business program. Some of the startups she has worked with included Elaine Transportation, Nakira's World and NP Skills Made Easy, among others.

"Being a mentor means helping someone see what is possible while being honest about what it will take to get there," Bickham says. "It is not about giving generic advice or telling entrepreneurs what they want to hear. Sometimes mentorship means offering encouragement, and sometimes it means asking difficult questions that help someone avoid an expensive mistake. In both situations, my responsibility is to listen, share what I have learned, and help the entrepreneur make an informed decision. ... Being a mentor also means opening doors when I can—making introductions, inviting entrepreneurs into rooms they may not have entered on their own, and helping them build relationships that can change the direction of their businesses. It also means holding them accountable for what they said they wanted to accomplish. I do not measure successful mentorship by how often someone returns to me for an answer. I measure it by whether they become more confident, more strategic, and better equipped to make decisions on their own."
