How much traffic do you drive per month? There are exchanges / SSPs that would do an integration with you but that is going to require scale.
Pretty much any SSP is going to ask you for a minimum of pageurl or app-level data in order to prevent fraud on their end.
I'm sure you already know, but you are going to take a big hit on eCPMs as a lot of advertiser money is connected to behavioral segments (and thus cookie / device id data).
Is your site general focused or do you have a specific niche? Some specific niches (eg targeting programmers) will be able to pull in significantly more through direct sponsorships and/or ad networks specializing in your vertical.
