Participate in royalty-based venture financing. In traditional venture financing, an investor buys a stake in a company to provide growth capital to its founders. This investor is then entitled to a percentage of the gains experienced when a company is bought or has an initial public offering. However, there is another kind of venture financing where an investor can invest start-up capital in exchange for regular royalty payments that are based on the company's revenue. This doesn't give the investor any ownership in the company, but does guarantee regular payouts (assuming the company survives).
Some people define passive income as money you earn while sitting on a beach sipping a good drink. But don't let the word "passive" mislead you, because there is usually a lot of upfront work involved. Passive or residual income is money you earn while not being actively involved after an initial investment of time and/or money. Some methods require you to have some cash to spend initially, while other ideas don't require any spending at all. Here are some suggestions on how you too can generate passive income.
Decide to invest in dividend stocks. Dividend stocks pay out a portion of the company's profits to shareholders. These dividends are paid at regular intervals, so they produce a regular income stream. Investors who hold a large amount of this type of stock are known as "income investors" because they prioritize regular dividends over stock value growth.[1]
