I came across this neat tool that helps to set up meetings with colleagues or friends avoiding the endless e-mail exchanges or SMSs until you finally find a common day and time to meet for dinner, drink or whatever.
The founder would probably think it is more than a "tool" and I am sure he will find like-minded VCs who will fund his business. If not, it should be easy for him to do a very early sale to one of the many collaboration or social network sites.
I used this tool and it works nicely. Some improvements are necessary, such as more online calendar (Web 2.0) supports, but with just $37k self-financing lots has been achieved. Try it out and see if you like it too!
