Before Don Frieden started his company, gas stations hadn't innovated their payment technology since 1997. He knew that needed to change.

P97, founded in 2012, exists to use innovative technologies to simplify and energize daily journeys, Frieden explains on the Houston Innovators Podcast.

"We think about daily journeys from the time we leave home in the morning and when we get back at the end of the day — whether it's tolling, parking, buying fuel, fast food restaurants, it's all a part of your daily journeys, and our goal is to make things a little bit simpler each day," Frieden says on the show.

The fast-growing company — which has nearly 200 employees, most of whom work from Houston — has raised over $100 million in venture funding, according to Crunchbase, most recently closing a $40 million series C round earlier this year. This funding has supported P97 as its expanded its technology, even expanding outside of gas station payments and into other sectors, like consumer packaged goods, mobile app development, and alternative fuel sources.

Part of what P97 is focused on too is adapting new technologies, including biometrics, and applying them to the payments world. Voice-enabled payments is something in particular that Frieden is working on.

"One of the things we’re most excited about is voice enable payments through our partnership with Amazon's Alexa," he explains. "The landscape of payments at gas stations underwent this next revolution, and we're using cutting-edge speech recognition and artificial intelligence to allow drivers to pay for fuel just using their voice.

"It makes the process faster and more efficient, and is completely hands-free," he continues, explaining that biometrics are also safer compared to card transactions. "From this time I say, 'Alexa, buy gas,' six seconds later, the gas would be turned on and any loyalty rewards I have would be applied, all from the comfort of my car."

Frieden shares more about the future of P97, payments, and the energy industry as it intersects with P97 — including the future of alternative fuels — on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.
