We setup a presentation that included 8 different individual businesses (total headcount in the meeting/presentation was about 20); My business partner knew some of these folks and invited them to hear our offer. The others, we emailed - not framed as a sale but to check out our technology and provide feedback.

After the presentation, we had 2 businesses ready to cut us a check and 3 that later signed and the others provided us valuable feedback and references.
