Episode notes
Inevitable Commoditization of Infrastructure
- Infrastructure in programmatic ad tech is destined to be commoditized, reducing margins over time.
- Market consolidation will drive fewer, more efficient players serving both publishers and buyers.
Rejecting Traffic Arbitrage Publishers
- Index Exchange rejected 'made for advertising' publishers due to traffic arbitrage and dubious content.
- This stance differentiates Index as accountable to supply quality, pushing standards higher in the industry.
Enable Innovation Above Infrastructure
- Drive adoption by enabling companies to add value on top of your infrastructure rather than trying to be the sole optimizer.
- Focus on scale and efficiency while letting partners innovate on curation and outcomes.
