Blockboard helps iconic American brand Eight O’Clock Coffee achieve a significant increase in incremental sales and ROAS compared to other CTV partners.

272% ROAS vs. 0% ROAS with other CTV partners

The Challenge

An iconic American coffee brand, founded in 1859 and renowned for its creative marketing (e.g., the famous steaming cup Times Square billboard of the 1930s), was looking for new ways to innovate with advertising to compete in an increasingly crowded category.

Blockboard's Approach

Blockboard implemented rigorous, blockchain-enabled, pre- and post-bid verification to ensure a 100% human audience, targeting high-profile geolocations with precision across premium streaming CTV. Verified viewers who watched 96% of the ad were retargeted, with Nielsen sales data used to verify the actual sales lift generated by Blockboard versus the two largest CTV platforms.

The Results

Blockboard helped the client reimagine its media strategy with precision-targeted CTV. Using pre- and post-bid blockchain verification, Blockboard ensured ads only reached a 100% human audience and retargeted high-intent viewers to maximize impact. Nielsen-verified results showed a 272% increase in ROI—far outperforming two of the industry’s largest CTV platforms, which delivered zero measurable lift.
