Our team

We love technology—especially when it makes people’s lives easier. The Blackbox is backed by founders with more than 20 years of aviation experience. Whether at the airport or working directly with aircraft, we know the processes—and the weak points. That’s why we created a tool that picks up where others stop: with your suitcase.

Our own need drove us.
