Our Vision

We create innovative, customer-centric and cost-efficient solutions based on modern tech stack, close collaboration and deep knowledge of business processes.


Our History

We founded Airxelerate in Berlin in 2018. Our solutions are based on years of development work and more than a decade of expertise of the founding team in the travel tech sector. Until the founding of Airxelerate, Nina Sifi and her co-founders Kristian Herpel, Kai Prozeller and Timur Sahin were responsible, among other things, for managing all of Air Berlin's commercial systems.
With our Calisto products we overcome the technical boundaries between airlines and tourism and are a competence for data management and sales in tourist sales channels. With agile structures and modern tech stack, our cloud-based solutions reduce complexity and costs. Building on decades of expertise, we, as founders of the Berlin start-up, are breaking a new ground in the travel technology.
