The Creative Velocity Gap: Why Ad Variant Throughput Now Sets Agency Margin

Ad platforms have automated bidding, targeting, and creative testing by default, so the remaining human-controlled lever is how many on-brand variants an agency can ship per week. Creative ads generation turns that lever into a throughput problem: teams that produce 50 tested variants where competitors produce 5 learn faster and defend retainer value with evidence instead of opinion. The risk is homogenized output, because undifferentiated AI creative erodes the differentiation clients actually pay for.
