Me too. If anyone has good experiences that would be great.

@Runfun - who are you using now. My G account manager gave me access to set up DFP but I dont have a clue what I am doing!

It wouldn't be nice if someone of my current header bidding partner reads this lol. So I'm looking for other options just in case things change or I want another partnership.

Hope someone comes along with some possibilities.

I need a network like now because I can't link my Adsense account without an Adx or header bidding network.

You do not need to "link" your AdSense account. I have been using DFP showing only AdSense since I started a few month ago. DFP shows that I am earning, but the AdSense reports are not transparent, but as far I can tell I am being paid for the DFP impressions.

That said, for recommendations, I came across Unified Ad Marketplace which is Amazon's header biding solution. It looks interesting. It is invite only, you can request an invite on their website. I haven't used them so I can't recommend them but given that is owned by Amazon suggests that it must be a serious company. I requested an invite, I am waiting to hear back.

I was invited by Amazon I think early in 2018 and they began setting it up for me, got halfway and then told me that their process only works if your DFP is in USD currency. So beware if any of you are outside of the US and have your DFP in another currency, it won't work. They did say that they are looking to roll out non-US currency support later in 2018.

Thanks for the tip. Just to ask you again, my DFP will be in UK pounds so does that mean I cannot use US providers? What about a prebid solution would that work?

No, this isn't a problem at all. We set-up header bidding for a lot of publishers who have non USD Ad Manager accounts. We plug in demand that trades in various currencies. In our case we also offer access to AdX. In our case that trades in GBP whatever currency the Ad Manager account uses and doesn't cause a problem at all. (We're UK based ourselves, so have probably encountered this situation more than most, but it is pretty straight forward. We also use prebid).

Going back to the original question: There are companies like us who set-up header-bidding and also bring demand from our relationships with networks/exchanges. We also add additional demand through exchange bidding where the publishers set-up allows. There are quite a few companies out there offering this, but results and service do vary a lot. If you are looking for AdX demand as well I would recommend looking for a partner that is part of the Google Certified Publisher Partner programme so that you also get the additional support route into Google, and the assurance that nothing will be done that will jeopardise your relationship with Google (who are after-all by far the biggest demand source). Most work on revenue share basis only and you'll make more after revenue share than you would be likely to on your own unless you can put significant resource into doing it yourself.
