We would all like to think, "If I build it they will come." But this is not necessarily true. 100 years ago, if you build a better mouse trap investors would beat a path to your doorsteps. But not now. What you need to do is mount a two prong marketing campaign aimed your target user audience or clients and also at your investors. Use language like, "Select Investors invited to Inquire." Not the exact words, but you get the point. Don't beg if you have a MVP.

Best of Luck,
