About

SkyCrunch (SkyCrunch.com) builds trip-planning and cost-intelligence software for business aviation. When flight crews plans a route, they need to know what fuel and ground handling will cost at each possible stop. This information is scattered across hundreds of fuel suppliers and FBOs (Fixed Base Operators, the companies that handle aircraft on the ground), most of whom still quote by email. We aggregate this information, normalize it, and put it on a map so an operator can compare stops in seconds instead of hours.

We're a small team moving at a fast pace. What we need now is someone to own the layer between the aviation world and the software: getting the pricing data in, understanding what it actually means, and turning that understanding into things we can build.
