Clickadu is a global ad-tech platform founded in October 2014 in Prague, Czech Republic. Starting as a popunder-focused network, it has expanded into a multi-format self-serve platform delivering over 6 billion daily impressions across 150+ countries. The company connects advertisers and publishers through display, video, native, and push advertising formats, leveraging AI-driven ad rotation and machine learning-based fraud filtration. Clickadu's mission is to provide high-quality traffic solutions with transparent statistics and 24/7 support. With a decade of operational history, the company has introduced six distinct ad formats, proprietary tools like IP capping and anti-adblock, and both a Publisher's SSP and Advertiser's SSP. It serves a global client base of media buyers, affiliate marketers, and website publishers. The company is registered as Clickadu s.r.o. in the Czech Republic and maintains its headquarters in Prague. Over 6 billion daily impressions, 3 billion unique monthly users, and partnerships with major affiliates like Zeydoo underscore its scale. Clickadu has bootstrapped its growth without external funding rounds, staying privately held.
Detailed Review
Company Overview
Clickadu positions itself as a reliable, high-volume ad network with a decade of operational history. Its strength lies in its diversified ad formats—banners (300x250, 300x100, 728x90), popunders, in-page push, video pre-roll (IAB VAST compliant), instant text message dialogs, and SKIM links—which allow advertisers to reach audiences across both web and mobile environments without relying solely on push notification subscriptions. The platform’s AI-based ad rotation (introduced in 2023) optimizes delivery for performance, while its fraud filtration system uses machine learning to minimize invalid traffic.
Business Model and Monetization
For publishers, Clickadu offers a straightforward monetization solution with high CPM rates, 100% fill rate on banners, and a variety of payment methods (more than five options). The self-serve interface provides real-time statistics and campaign automation. Advertisers benefit from fast moderation (often launching within minutes), IP capping, and the ability to target users across 150+ geos.
Market Position and User Feedback
User feedback on third-party review sites (e.g., Trustpilot, Business of Apps) tends to be positive, highlighting responsive support, consistent payouts, and transparent reporting. Some users note that the platform’s traffic quality can vary by vertical and geo, but the company’s long-term partnerships with major affiliates (e.g., Zeydoo) suggest strong retention and trust.
Recent Developments and Innovation
Clickadu’s history of steady innovation—from launching its first SSP in 2016 to introducing in-page push in 2020 and AI rotation in 2023—demonstrates a commitment to staying competitive in a crowded ad-tech space. However, as a private company, detailed financials and client concentration remain undisclosed. The company has not publicly reported any external funding rounds, suggesting bootstrapped growth.
Conclusion
Overall, Clickadu is a solid middle-tier ad network suitable for performance marketers and publishers seeking reliable, high-volume traffic across multiple formats. Its decade of operational track record and active product roadmap make it a dependable partner in the programmatic advertising ecosystem.
