The issue facing the company is that unless you go whole hog and get listed on an exchange, and thus provide a prospectus to everybody and his brother so that you can sell a share here and a share there - you face the problem that you can only sell to qualified investors who can sign up to qualify as sufficiently financially stable and knowledgeable to take a hit and not complain later to securities authorities etc. In general terms if you can sign up for 100 k or so then it is worth the legal fees for the required declarations and non disclosure agreements etc which are necessary. Thus the number of 100 k has been discussed.
