Clickadu has been running since 2014 out of Prague and has grown into one of the larger dedicated pop networks, claiming upward of 6 billion daily impressions across 240-plus geos. For adult buyers the draw is direct publisher inventory - the network works with 15,000-plus sites and prices traffic on CPM, SmartCPM, or SmartCPA models, which makes budget control straightforward whether you are running a test or scaling a winning funnel. Anti-fraud filtering is built in, and account managers are reachable without enterprise minimums.

The self-serve interface is polished but the sheer volume of targeting knobs takes an afternoon to learn. Start with SmartCPM to let the system find efficient placements before locking in manual bids.
