75% drop in CPA. 9x spend scale.

Those are the numbers Hannah Parvaz and her agency, Aperture, hit after making Luma their production layer. But the real story isn't the output—it's the infrastructure.

Aperture built an OS around a living record of every brief, hypothesis, and campaign result for every client. Think of it as a new production system:

The Intelligence Layer: Handles the heavy lifting of volume and variation, powered by a living record of past briefs, creative hypotheses, and previous work.

The Human Gate: Expert creative directors guide new hypotheses and provide the critical pass on quality and craft.

The Loop: Performance data feeds right back in, so every iteration learns from what actually worked.

Workflows compound campaign over campaign, and Luma handles the scale so Aperture can focus entirely on their craft. The real question for agencies isn't which model to use—it's what production system is being building around them.
