HopStop, a service that lets users map out the quickest subway route between two points in a city, has raised unspecified angel funding from a group of investors that includes Yaron Galai, founder of Quigo. The NY-based says it has passed 1.5 million pageviews a month (at least a few of which are my own). It’s not clear what the funding will go towards, other than the vague accelerating growth. In addition to the basic web service, HopStop offers mobile and voice access, as well as a service that allows businesses to offer directions on their own sites. Release.
