You are asking one question and inferring another. Do you want to know if it is possible to raise that amount on a crowdsourced site or are you asking for the best crowdsourcing site for your fundraising?

In short, yes. It is entirely possible to raise that level of funding without a VC and on crowdsourced platforms.

You obviously need to know the differences between "general public" crowdsourced audiences and professional VCs; they are looking for different returns. The casual crowdfunder is generally looking for something tangible (that is why sites like Kickstarter work so well) as well as a financial incentive.

VCs are looking for a return on their investment.

The casual crowdfunder is more likely to be sold on the idea of getting in on the ground floor and being part of something bigger than their usual life.

If you can clearly identify what problem your product is solving, and who will benefit, you can build your incentives around complementary frustrations and painpoints.

If your product is an accounting application for small business, for example, find partner services that also help small businesses.

If you have other questions, or I wasn't specific enough in some areas, please book a call with a couple of times that work for you and we can dig deeper.

To your succes,
