The process of collecting a large pool of investors, each contributing or investing a small amount of dollars for a highly focused project is referred to as crowdfunding. The crowd is financing the project or goal. This is very similar to how large non-profits address significant events worldwide. A good example is the American Red Cross addressing disaster relief in the aftermath of a major natural tragedy.
Non-recourse debt is a form of loans whereby the lender relies on the value of the collateral and no other party in case of default on the loan. This is not a common type of loan in the business world due to the volatility of most assets. In general, non-recourse loans are only used in very low risk capital needs situations such as real estate or the purchase of financial instruments (bonds and annuities).
