Attentional operates at the intersection of brand credibility and customer acquisition. We provide the performance marketing infrastructure that connects premium publishers and high-growth brands.
Our Origin Story
The next chapter for publisher monetization.
Attentional was founded on the belief that there was a better way for advertisers and publishers to work together in the age of performance marketing. After more than a decade leading the global advertising business at Condé Nast, Craig Kostelic saw firsthand how publishers created immense value for advertisers, yet an increasing share of advertising dollars flowed to platforms instead of the brands that built the trust and credibility that influenced the purchasing decisions. At the same time, performance marketers were under constant pressure to find more efficient customer acquisition channels.
Bryan Schindelheim and Timothy Tan came from the opposite side of the ecosystem, with deep experience in performance marketing, customer acquisition, and building products around emerging digital platforms. They understood how performance advertisers buy media, how they measure success, and how difficult it was to scale trusted acquisition channels without adding operational complexity. Together with Craig, they recognized an opportunity to connect these two worlds. By combining the trust and influence of premium publisher brands with the buying workflows and technology performance marketers already use, they created Attentional - a marketplace that connects advertisers with trusted publisher partnerships across every major performance channel while unlocking a new, scalable revenue stream for publishers.
The vision was simple: make buying through publishers as seamless, measurable, and performance-driven as buying directly on the platforms themselves.
Respect the Equity
Publishers spend decades earning audience trust. Every product we build must protect that hard-won integrity as the ultimate asset.
Demand Performance
Vague impressions aren't enough. We design systems that deliver measurable business outcomes, proving value at every scale.
Complete Control
No black boxes. Buyers run media through their accounts; publishers approve every single campaign before it goes live.
