Fonolo

Fonolo is a startup with a different take on contacting big companies with large, complicated phone trees.  The company has written software to spider phone trees and create a web-based picker tool. 

Once you traverse the web-generated tree, Fonolo will dial that company, follow the path you set up and then wait on hold for you.  Once your call is connected, your callback number is dialed.

It’s still in closed beta, but very cool thus far.
