About FLYR’s product
Cirrus™, our Revenue Operating System, is deployed by major commercial airlines both internationally and domestically. Cirrus leverages an extensive data- and deep learning infrastructure that was built from the ground up to solve airlines’ most complex commercial challenges.
Founder Alex Mans started FLYR in 2013, initially with the intent to remove inefficiencies in airline pricing for travelers. Since then, we've shifted focus to address the forecasting and pricing problems at the core of major airlines, and we have built a team with a wide range of experiences in enterprise technology, aviation, and entrepreneurship. We are a dynamic and fast-growing travel tech start-up headquartered in the SoMa neighborhood in San Francisco with a European development hub in Krakow, Poland.
Impact of COVID-19
While the effects of COVID-19 on commercial aviation (our primary client base) have been widely publicized, demand from airlines around the globe has exceeded all expectations. On the back of incredible outperformance compared to legacy incumbents in our space, we are on track for an exceptionally strong 2021 and beyond. While the road to travel recovery isn’t easy, you won't find any other industry as dedicated to continuous improvement and reinvention.
Our Commitment to Fairness
At FLYR, we are proud to be an equal opportunity workplace and embrace a commitment to have our teams better reflect the world around us as we scale the business.
