A matrix scheme (also known as a matrix sale or site, and as a hellevator, escavator or ladder scheme) is a business model involving the exchange of money for a certain product with a side bonus of being added to a waiting list for a product of greater value than the amount given. Matrix schemes are also sometimes considered similar to Ponzi or pyramid schemes. They have been called "unsustainable" by the United Kingdom's Office of Fair Trading. A matrix scheme is also an example of an 'exploding queue' in queueing theory.
The first known matrix scheme is widely believed to be EZExpo.com, which started the popularity of matrix schemes in 2002. By 2003 more than 200 matrix schemes were in operation, including one which had the same owner as the payment processor Stormpay (TymGlobal). Subsequently, both TymGlobal and Stormpay were accused of running an illegal Ponzi scheme. Stormpay later claimed to be independent of TymGlobal, and they stopped accepting matrix schemes as customers. Although many have since ceased trading, some schemes are still known to be operating worldwide. The payment processor, Stormpay, is no longer trading.
The operation of matrix schemes varies, though they often operate similar to pyramid or Ponzi schemes. Some of the former participants of these schemes consider them to be a form of confidence trick, although others are happy with their purchase. To move upward in the list, a person must wait for new members to join or refer a certain number of people to the list. This is accomplished through purchasing a token product of marginal value: usually e-books, cell phone boosters, screen savers, or other software CDs/DVDs. When a pre-defined number of people have purchased the token product, the person currently at the top of the list receives their reward item, and the next person in the list moves to the top. The rewards for those at the top of the matrix list are usually high-demand consumer electronics, such as portable digital audio players, high-definition television sets, laptop computers, and cellular phones. Reaching the point on the list where one receives the expensive goods is termed "cycling".
In many cases, the token product alone could not be reasonably sold for the price listed, and as such legal experts claim that, regardless of what is said, the real product being sold is the "reward" in question in those situations. In these cases, the operator could be charged with running a gambling game or failing to supply ordered products. Steven A. Richards, a lawyer who represents multi-level marketing (MLM) companies for Grimes & Reese in Idaho Falls, Idaho, has stated that often there are no clear legal tests for Ponzi schemes. But if the product sold has no value or very little value, and consumers wouldn't buy it without the attached gift, the scheme probably runs afoul of federal and state laws.
