What are foreign bid managers for Facebook?

Question

Facebook

What kind of bid managers are there whose companies are not based in Russia/CIS?
Interested in foreign bid managers following the example of elama/aitarget.
The key parameter for choosing is to work on agent accounts in FB, so that I would be advertising from the accounts that we will be given, and not from those that we set up ourselves (as in elama where accounts do not need to be created, but they are issued by the bid manager himself)
