They sell make up. They call their reps ambassadors. Susie Ma won The Apprentice in 2011 and set up her Tropic business with Lord Alan Sugar, with him sharing the business 50/50 with Susie.
They don’t have an income statement but they do have this-

Let’s see if we can work out the average income. We can assume that a few people started in 2011 and the numbers grew year on year. We can also assume that a lot of people joined and then left. Let’s try and cancel these facts out and assume there were, on average, 8000 people from the beginning and no one left the scheme. In reality, the number of total reps, past and present, would be more so we are being generous.
If there were 8000 reps and they earned £13 million between them, each one will have earned £1,625 in total. If you break this down to a yearly amount, it is £232.
Roughly then, each rep will have earned on average £232 a year, less expenses. Even if these figures are wrong by a factor of 4, this would still be a very poor earning potential.

There is no information on their website about how much it costs to join. A rep in a webchat stated in 2011 that it costs £120 to join"
