Interestingness

I got some feedback to my last post (and feel free to post comments, this is a blog after all) and have been doing some further research. Some new companies that strike me as ‘interesting’, because they have a novel product or a novel approach to the market or both include:

Obopay - a mobile payments system that people might actually use
Shozu - upload pictures from your cameraphone to your blog or favorite photo-sharing site, not the web site of your mobile operator
Admob - an advertising network for mobile phones that borrows from Google and Overture instead of Doubleclick
Musicgremlin - a music player that isn’t tethered to a PC or to your mobile operator

Obviously these are all consumer-facing companies. Any other suggestions? Right now I am interested in companies with innovative products and/or strategies, not new ringtone download sites, new games publishers, or - least of all - new names for old companies.
