Jigsaw

Have you seen Jigsaw?

Jigsaw is an online database for the trading of virtual "business cards". They have an extensive database of contact information within thousands of companies across multiple veriticals including, in all probability, yours.

There are two models for membership: Pay, and Play.

You can either "pay"for access to the information stored in Jigsaw's base, or you can "play" the system by earning redeemable points which you can use to purchase information. You can earn points by updating and/or correcting faulty data, by referring friends to sign up and create accounts on Jigsaw, or by adding information to the database that isn't already there.

It's a nice resource to use in conjunction with a resource that gives you names and titles only, because you can then use Jigsaw to look up more specific contact information.
