Carson, you indicated that it is difficult in this community to find genuine principals who are ready for investors. Likewise, it is difficult for the principals of a small business who
are ready for outside funding to find genuine investors here.
In my experience, the process never begins with sending a detailed business plan to a
gmail address. (Genuine business owners might assume that rather than being a qualified investor, you are merely collecting business plans to adapt to non-US markets for resale or implementation. I'm not saying that's the case with you -- only suggesting that many business owners would see your request as jumping directly to a "third date" level of intimacy without having had the first two yet.)
The first thing a genuine investor normally wants is evidence of "traction" -- something that shows the business is poised to take off. Unfortunately, business owners who hit this site are not very good at that. They make posts asking for money, but fail to provide a potential investor or lender with any reason whatsoever to give it to them. That's "their bad."
The second thing a genuine investor wants is to really get to know the principal -- to determine if this person has the competence and commitment to grow the company. And the principal wants to get to know the investors -- to determine if they are really qualified to fund the deal and if everyone can work together.
Provided the first two "dates" work out, then things get serious (detailed business plans, due diligence, term sheets, etc.).
My suggestion to business owners seeking investors here would be to include profile information and post your "elevator pitch" so you can provide some traction. My suggestion to investors like yourself would be to provide profile information and respond to good posts by offering information about your own background and qualifications, and requesting the same from the business owner so you can get acquainted and "size each other up." If you decide to move forward from there, then you can get into the business details.
A final suggestion for legitimate lenders and investors: When someone posts, "I have no assets, bad credit, I'm $15K in debt, was just released from prison and can't find a job -- so I need $300,000 to start my own business . . ." ignore it. Anyone who posts a response that says something like, "Contact me, I can help you get the funding you need" is not going to be seen by the
genuine business owners on this site as a legitimate lender or investor.
I hope this info helps legitimate investors and serious business owners connect -- because, as you noted, it isn't always easy. Best wishes.
