2. Stalk and awe.
Some potential customers will always be totally out of your reach but might make incredible early adopters. I like to employ my signature "Stalk and Awe" campaign. First, I stalk these people -- not the kind of stalking that’s an unwanted, obsessive intrusion on someone’s personal space that can lead to arrest.
Find anyone who might have a connection to the person you want to meet and ask for an introductory email or a warm up call. The harder this person is to reach, the more recommendations you'll need. Next, send a letter of introduction and follow up with a call. Locate opportunities to attend events where the person will be so you can “run” into them (networking and business events only). I'm not suggesting crashing a wedding or joining the person's gym.
If you're able to arrange a meeting, now awe this person. Do research on potential problems in his or her business. Spend the first half of the meeting asking questions to locate possible pain points for that person and try to offer something of value independent of your business. Then if you bring enough value to the table and awe this person, he or she will be a lot more interested in you and your company.
