Is there an obligation to run the campaign within its DSP account ?
Yes !. Not that I am aware of....
PBU, but discuss it with Simon.
Is he insisting specifically on having the media-costs and detailed costs of its campaigns ?
Yes, he is. No or Not specifically.
Go for Xaxis.
Did he received a presentation over Xaxis and the products ?
Yes. No, not yet.
That means something is not clear enough for him. Check with Simon to organize a meeting with him. If it cannot be done before the start, then go for PBU this time..
Do we have enough time for a 1h meeting before the start ?
Too short. Yes, that might be possible.
Let's present them Xaxis and suggest a test campaign.
Go for PBU for this campaign, but let's present them Xaxis.
Is he open to test Xaxis ? or against Xaxis ?
i think there are some global discussion. No, he does not want to hear about it. Yes, he's open.
