Sisel is an MLM primarily in the health and drink mix niche.
Although Sisel is not the oldest company, only being founded in 2006 by Tom Mower Sr., it is among the most recognizable of many direct marketing companies.
The strange name that is pronounced sizzle is actually an acronym to remember what the company stands for, science, innovation, success, energy, and longevity. The company prides itself on producing innovative products and distributing those products through sellers in over 40 countries worldwide.
Sisel has been around for just over a decade without any real negatives being brought to the company, so they are obviously doing something right. But whether or not that will help you make money is the real issue at hand.
