About Caravelo
Caravelo is a travel-tech company with a global team and roots in Barcelona that specializes in subscriptions. We make travel better and more accessible by enabling our clients to offer better products and helping them to become more profitable and more stable businesses.
Our team has been growing over the past few years and at the moment we are a team of 50 people working mostly from our HQ in Barcelona. If you’d like to be part of our growth journey, read on. 
Our platform is based on a SaaS architecture in a cloud environment on Amazon AWS. The domain of our subscription platform for travelers uniquely combines two different domains: the financial domain (Fintech) and the travel domain (Travel Tech).
