PAMM is essentially you investing in other traders. They take a small cut, but only off profits.

PAMM stands for Percentage Allocation Money Management. Many people mistakenly take this for the well-known PMAM (Personal Multi Account Manager).
Both are intended for use by more experienced traders. They are excellent tools for pro traders who are willing to manage other people's money, but one can also use this solution for one's own capital.
Although they have some similarities, PAMM has more options. The feature that makes the difference is that with this solution, a trader who manages other people's funds can pool all the funds together and trade with a larger position size, consequently improving the portfolio's performance. The tool automatically sorts out the profit share according to each person's share in the account size.
There are other interesting features, but in brief, this is what you need to know about PAMM

PMAM stands for Personal Multi Account Manager. As the name suggests, it is a platform from which a trader can manage multiple trading accounts. Let me make it clear how it can be used and by whom, through an example.
You probably have stumbled upon some advertisements from people that offer account management services. You create an account, deposit funds and let them do the trading for you. Of course, they will keep a certain percentage of the profits made as their service fee or whatever you want to call it.
Well, what happens on the other side is that the person most likely uses PMAM. How does it work? Simple. He has created a mother account, which is most likely his primary trading account. Then he can add multiple trading accounts that will mirror the trades from the mother account.
I hope I made it clear to you through this example.
