Which platform can I raise funding on for a medical portal where you can upload your medical documents and make medical reports?

It's not foolish, but it's going to be extremely hard to pull it off. I would consider starting with a beta program so you can have some paid clients to pay for the company's expenses. After you have some traction, you can raise a seed round.

After shepherding 300 equity crowdfunding raises through our platform I'd say all of them have a higher valuation. Reason is it is the entrepreneur that is calling the shots. It is the entrepreneurs offer on their terms on an equity crowdfunding platform. Once you get outside investors involved shaping the deal the valuation will most certainly go down. Agreed it may then be more realistic as everyone believes their company is more valuable than it is. My advice? Treat early investors fairly. Money is the lubricant to get your idea into reality. Give them a fair share of the business and they will reinvest when need be.

I'd need to understand a bit more about your business, but I suspect one answer is to work toward getting an accounts receivable-based credit line. Amazon is a good company that pays it's bills. Lenders will either loan against the Amazon receivables or buy them from you at a discount. This approach is expensive but if cash flow is your issue, worth exploring.

Apps are difficult to fund on IndieGoGo as few are successful, and we rarely take them on as clients. Websites like http://appsfunder.com/ are made for that very reason, but again, difficult to build enough of a following willing to pay top dollar for an app that could very well be free, already existing in the marketplace. A site that is gaining more traction you may want to look into would be http://appsplit.com/. Again, Appsplit Is Crowdfunding For Apps specifically.

As someone who has founded and fundraised for a social venture, I can tell you that the fundraiser must be the CEO or President. Fundraising for a non-profit is all about building a relationship with your donor base, and the donation is often as much because the donor likes the person & people as much as they like the work being done by the Foundation. One of the most difficult paradoxes of raising for a non-profit web platform is that the more someone becomes excited by the potential of the platform, the more that they would prefer to invest cash for equity than simply donate and looking back on it, I think that would have simplified things for my social enterprise and would have been able to attract far more capital. The other avenue that you can explore is to build in tipping or crowdfunding for your operation directly into the online experience but that will only be a viable source of funds with significant traffic and thus, the operating capital required to grow the business requires proactive outreach to supporters. Happy to speak with you about this in more detail in a call.
