If possible, meet your prospects in person. Go to industry events, shows, etc. Have a 20 sec pitch NAILED. Practice it incessantly on friends and family--anyone should be able to "get it" no matter how technical the product. Tailor it to their needs, not features. Make your goal to get an actual meeting with someone. Prepare a very short written "pitch" presentation. Make it look good. Rinse and repeat. As others said, let rejection fuel--not discourage--you.
