An artificial intelligence startup targeting air travel has raised $34 million in a funding round led by Andreessen Horowitz to more aggressively pursue deals with the US Department of Defense.

Air Space Intelligence Inc. has long sold its tools — which have been described as Waze for air travel — to commercial carriers including Alaska Airlines. The startup’s marquee product, called Flyways, can help flight dispatchers pick routes for planes, taking into account factors like flight traffic, weather and airport conditions.
