The OpenX alternative for event directories
OpenX is a programmatic supply-side platform for large publishers. For event directories selling to venues, event services, and local brands, DirectoryAdServer is a directory-first ad server with sponsored listings, ad-buy packages, and flat-fee pricing that lets you keep every dollar of ad revenue.
The gap
Why OpenX isn't built for event directories
OpenX is an auction-based exchange built for programmatic scale — it is the opposite of selling a handful of placements directly to local sponsors, and it takes a share of the demand it brokers.
Event directories sell in short bursts around event dates, so they need time-boxed campaigns and packages that map to sponsorship tiers rather than always-on banners. A directory serving event-goers and attendees needs to sell time-boxed sponsored placements tied to event dates — and OpenX runs on revenue share on auctioned programmatic demand, which works against a directory selling placements directly to venues, event services, and local brands.
The fit
